Bucket是Redisson 的基本数据结构，类似于Java的Map。
可以用来存储任意类型的对象。
2. getList()方法：用于获取分布式列表。
分布式列表类似于Java的List，支持插入、删除、遍历等操作。
3. getSet()方法：用于获取分布式集合。
分布式集合类似于Java的Set，支持添加、删除、判断元素是否存在等操作。
4. getMap()方法：用于获取分布式映射。
分布式映射类似于Java的Map，支持添加、删除、查询等操作。
5. getSortedSet()方法：用于获取分布式有序集合。
分布式有序集合类似于Java的SortedSet，支持按照指定的排序规则插入和查询元素。
二、执行分布式操作1. execute()方法：用于执行一个分布式操作。
可以将实现了RCallable 接口的Lambda表达式传递给execute()方法，然后在Redis服务器上执行。
2. getExecutorService()方法：用于获取分布式ExecutorService对象。
可以用它来提交任务，并在Redis服务器上执行。
支持异步和反应式编程模型。
3. getRemoteService()方法：用于获取分布式服务对象。
一个由于springboot自动配置所产生的问题的解决
⼀个由于springboot⾃动配置所产⽣的问题的解决 由于我的项⽬⾥⾯需要使⽤到solr,我做了⼀下solr和springboot的整合,结果启动项⽬的时候,就报错了...报错的信息的第⼀⾏提⽰如下:org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'solrClient' defined in class path resource [org/springframework/boot/autoconfigure/solr/SolrAutoConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException:Failed to instantiate [org.apache.solr.client.solrj.SolrClient]:Factory method 'solrClient' threw exception;nested exception is ng.NoSuchMethodError: org.apache.solr.client.solrj.impl.HttpClientUtil.createClient(Lorg/apache/solr/common/params/SolrParams;)Lorg/apache/http/impl/client/CloseableHttpClient; 我的和solr相关的pom坐标如下: <!-- solr --><dependency><groupId>org.apache.solr</groupId><artifactId>solr-solrj</artifactId></dependency> 我的SolrClient相关的配置如下：@Configurationpublic class SolrConfig {@Beanpublic HttpSolrClient solr() throws MalformedURLException {HttpSolrClient server=new HttpSolrClient("http://192.168.200.130:8080/solr");return server;}} 我当时就郁闷了,因为实际上我启动的这个项⽬并没有使⽤到solr..和solr相关的类在另外⼀个应⽤⾥⾯,只是这两个应⽤都是⼀个⽗模块下⾯的⼦模块,⽽所有的坐标我声明在⽗模块⾥⾯.因此,我第⼀时间想到的是可能会存在jar包的冲突,因此我做了很多尝试例如使⽤spring-data-solr坐标,或者springboot-starter-solr的坐标,结果发现都没有⽤,后来我跟进断点后,⼀步步跟着源码⾛,发现在应⽤启动的时候,springboot就给我创建了⼀个HttpSolrClient，⽽这个错误就是在springboot创建HttpSolrClient的时候报错的.说是找不到⽅法..不过,考虑到我也不需要去使⽤springboot的⾃动创建HttpSolrClient特性,毕竟SolrClient我们⾃⼰创建了并且放到了spring容器中了..因此我们必须要禁⽤springboot和solr相关的⾃动配置.在⽹上经过⼀番查找后,最终我通过在App启动类上指定禁⽌相应的⾃动配置类(根据报错的信息,就是SolrAutoConfiguration这个类)解决了这个问题.如下:@SpringBootApplication(exclude=SolrAutoConfiguration.class)@ImportResource(locations="classpath:conf/dubbo.xml")public class App extends SpringBootServletInitializer {@Overrideprotected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {return builder.sources(App.class);}public static void main(String[] args) {SpringApplication.run(App.class, args);}} 这个问题实际上也告诉我们,springboot的⾃动配置有时候也不是万能的,⾯对具体的情境,如果需要禁⽤某些配置,就在启动类上的@SpringBootApplication的exclude属性指定需要排除的⾃动配置类即可.。

java interceptorregistry 实现原理
java interceptorregistry 实现原理Java作为一种广泛应用于企业级开发的编程语言，其拦截器（Interceptor）机制在框架设计和应用中起到了重要作用。
本文将详细介绍Java InterceptorRegistry的实现原理，并通过具体案例分析，给出应用场景和实际应用建议。
1.Java Interceptor简介在Java中，Interceptor（拦截器）是一种AOP（面向切面编程）的实现方式。
它允许开发者在不修改源代码的情况下，对程序流程进行横向切面处理，实现代码的横切关注点（如日志、安全、性能监控等）。
InterceptorRegistry（拦截器注册表）则是用于管理和注册拦截器的容器，它允许开发者轻松地配置和启用拦截器。
2.InterceptorRegistry实现原理InterceptorRegistry的实现主要依赖于Java的两大框架：Spring和AspectJ。
在Spring中，拦截器通过@Bean注解进行注册，然后被注入到InterceptorRegistry实例中。
而在AspectJ中，拦截器的注册则依赖于AspectJ的动态代理机制。
具体来说，InterceptorRegistry的实现原理可以分为以下几个步骤：（1）创建拦截器实例：开发者根据需求创建特定的拦截器类，实现intercept 方法。
（2）注册拦截器：将拦截器注册到InterceptorRegistry实例中。
在Spring中，可以通过@Bean注解实现；在AspectJ中，可以通过@Aspect注解并配合@Before、@After等注解实现。
（3）启用拦截器：在应用启动时，InterceptorRegistry会加载所有注册的拦截器，并将其启用。
（4）拦截请求：当请求到达目标方法时，InterceptorRegistry会根据配置和优先级顺序，依次调用拦截器。
如果某个拦截器返回了True，则继续调用下一个拦截器；如果返回了False，则终止拦截器链。

They use the term "rationality" in the traditionaleconomic sense that assume that consumers behave rationally when they (1)______ carefully consider all alternatives and choose those that give them the greatestutility (i.e. satisfaction) in a marketed context. The term "rationality" (2)______ implies that the consumer selects goods based on totally objective criteria,such as size, weight, price, and so on. "Emotional" motives imply theselection of goods according to impersonal or subjective criteria--the desire for (3)______ individuality, pride, fear, affection or status.The assumption underlying this distinction is that subjective oremotional criteria do not maximize satisfaction; therefore, it is reasonable to (4)______ assume that consumers always attempt to select alternatives that, in theirview, serve to minimize satisfaction. Obviously, the assessment of satisfaction (5)______is a very personal process, based on the individual's own needs as wellas on past behavior, social, and learning experiences. What may appear as (6)______ irrational to an outside observer may be perfect rational within the context (7)______of the consumer's own psychological field. If behavior did not appear rationalto the person who undertakes at the time that it is undertaken, obviously (8)______he or she would not do it. Therefore the distinction between rational andemotional motives does not appear to be warranted.Some researchers go so far as to suggest that emphasis of "needs" (9)______ obscures the rational, or conscious, nature of most consumer motivation. Theyclaim that consumers act consciously to maximize their gains and minimizetheir losses; that they act on not from subconscious drives but from rational (10)______ preferences.IV. Reading comprehension (30%)A. Multiple ChoicePassage 1RUSSIA’S N EW REVOLUTION IN CONSERV A TIONWhen naturalist Sergei Smirenski set out to create Russia’s first private nature reserve since the Bolshevik revolution, he knew that the greatest obstacle would be overcoming bureaucratic resistance.The Moscow State University professor has charted a steep uphill course through a variety of foes, from local wildlife service officials who covet his funding to government officials who saw move value in development than conservation. But with incredible dedication, and the support of a wide range of international donors from Japan to the United States, the Murovyovka Nature Park has finally come into being.Founded at a small ceremony last summer, the private reserve covers 11,000 acres of pristine wetlands along the banks of the Amur River in the Russia Far East. Here, amid forests and marshes encompassing a variety of microhabitats, nest some of the world’s rarest birds—tall, elegant cranes whose numbers are counted in the mere hundreds.The creation of the park marks a new approach to nature conservation in Russia, one that combines traditional methods of protection with an attempt to adapt to the changing economic and political circumstances of the new Russia.“There must be a thousand ways to save a wetland. It is time fo r vision and risk, and also hard practicality,” wrote Jim Harris, deputy director of the International Crane Foundation, a Wisconsin-based organization dedicated to the study and preservation of cranes, which has been a major supporter of the Murovyovka project.Dr. Smirenski’s vision has been eminently down to earth. At every step, he has tried to involve local officials, businessmen and collective farms in the project, giving them a practical, economic stake in its success. And with international support, he is trying to introduce new methods of organize farming that will be more compatible with preserving the wetlands.1. The Murovyovka Nature Reserve came into being because of[A] Russian government officials. [B] the International Crane Foundation.[C] the determination of one man. [D] an unrealistic dream.2. If one “charts a steep uphill course” (paragraph 2), one[A] expects an arduous journey. [B] maps out a mountain trip.[C] assumes that life will be uneventful. [D] sets himself a difficult goal.3. The preserved “pristine wetlands” mentioned in paragraph 3 are[A] unspoiled. [B] precious. [C] immaculate. [D] uncontaminated.4. The passage states that the Nature Reserve is[A] an arid, uninhabited area. [B] the only reserve in Russia.[C] home to many different birds. [D] economically beneficial to local inhabitants.5. The passage implies that the preservation of wetlands[A] can only be accomplished with traditional methods.[B] requires imagination, daring and pragmatism.[C] is usually a popular concern of politicians.[D] limits an area’s development.Passage 2THE PEARL OF ORR’S ISLANDChapter IVThe sea lay like an unbroken mirror all around the pine-girl, lonely shores of Orr’s Island. Tall, kingly spruces wore their regal crowns of cones high in air, sparkling with diamonds of clear exuded gum; vast old hemlocks of primeval growth stood darkling in their forest shadows, their branches hung with long hoary moss; while feathery larches, turned to brilliant gold by autumn frosts, lighted up the darker shadows of the evergreens. It was one of those hazy, calm, dissolving days of Indian summer, when everything is so quiet that the faintest kiss of the wave on the beach can be heard, and white clouds seem to faint into the bluer of the sky, and soft swathing bands of violet vapor make all earth look dreamy, and give to the sharp, clear-cut outlines of the northern landscape all those mysteries of light and shade which impart such tenderness to Italian scenery.The funeral was over,—the tread of many feet, bearing the heavy burden of two broken lives, had been to the lonely graveyard, and had come back again, —each footstep lighter and more unconstrained as each one went his way from the great old tragedy of Death to the common cheerful walks of Life.The solemn black clock stood swaying with its eternal “tick-tock, tick-tock,” in the kitchen of the brown house on Orr’s Island. There was there that sense of a stillness that can be felt, —such as settles down on a dwelling when any of its inmates have passed through its doors for the last time, to go whence they shall not return. The best room was shut up and darkened, with only so much light as could fall through a little heart-shaped hole in the window-shutter,—for except on solemn visits, or prayer-meetings, or weddings, or funerals, that room formed no part of the daily family scenery.The kitchen was clean and ample, with a great open fireplace and wide stone hearth, and oven on one side, and rows of old-fashioned splint-bottomed chairs against the wall. A table scoured to snowy whiteness, and a little work-stand whereon lay the Bible, the Missionary Herald, and the Weekly Christian Mirror, before named, formed the principal furniture. One feature, however, must not be forgotten,—a great sea-chest, which had been the companion of Zephaniah through all the countries of the earth. Old, and battered, and unsightly it looked, yet report said that there was good store within of that which men for the most part respect more than anything else; and, indeed, it proved often when a deed of grace was to be done—when a woman was suddenly made a widow in a coast gale, or a fishing-smack was run down in the fogs off the banks, leaving in some neighboring cottage a family of orphans,—in all such cases, the opening of this sea-chest was an event of good men to the bereaved; for Zephaniah had a large heart and a large hand, and was apt to take it out full of silver dollars when once it went in. So the ark of the covenant could not have been looked on with more reverence than the neighbors usually showed to Captain Pennel’s sea-chest.6. Stowe describes Orr’s Island in a manner.[A] emotionally appealing, imaginative [B] rational, logically precise[C] factually detailed, objective [D] vague, uncertain7. According to the passage, the “best room”[A] has its many windows boarded up.[B] has had the furniture removed.[C] is used only on formal and ceremonious occasions.[D] is the busiest room in the house.8. From the description of the kitchen we can infer that the house belongs to people who[A] never have guests. [B] like modern appliances.[C] are probably religious. [D] dislike housework.9. The passage implies that[A] few people attended the funeral. [B] fishing is a secure vocation.[C] the island is densely populated. [D] the house belonged to the deceased.10. From the description of Zephaniah we can tell that he[A] was physically a very big man. [B] preferred the lonely life of a sailor.[C] always stayed at home. [D] was frugal and saved a lot of money.B. Read the following passage and answer the questions. Your answers should be given in English. Be brief and straight to the point. (20%)Small Kicks in SuperlandI often go to the supermarket for the pure fun of it, and I suspect a lot of people do too. The supermarket fills some of the same needs the neighborhood saloon used to satisfy. There you can mix with neighbors when you are lonely, or feeling claustrophobic (患幽闭恐怖症的) with family, or when you simply feel the urge to get out and be part of the busy, interesting world.As in the old neighborhood saloon, something is being sold, and this helps clothe the visit inwholesome material purpose. The national character tends to fear acts performed solely for pleasure; even our sexual hedonists（享乐主义者）usually justify themselves with the thought that they are doing a higher duty to social reform or mental hygiene.It is hard to define the precise pleasures of the supermarket. Unlike the saloon, it does not hold out promise of drugged senses of commonly considered basic to pleasure.There is, to be sure, the brilliant color of the fruit-and-vegetable department to lift the spirit out of gray January’s wearies, provided you do not look at the prices.There are fantastic riches of pointless variety to make the mind delight in the excess that is America. In my neighborhood supermarket, for example, there are twenty or thirty yards of nothing but paper towels of varying colors, patterns and thicknesses.What an amazing country that can make it so hard for a man to choose among things designed for the purpose of being thrown away!The people, however, are the real lure. As in the traditional saloon, there are many who seem determined to leave nothing for anybody else. These people prowl the aisles with carts overflowing with excesses of consumption. Twenty pounds of red meat, back-breaking cartons of powdered soap, onions wrapped lovingly in molded plastic, peanut butter by the hundredweight, cake mixes, sugar, oils, whole pineapples, wheels of cheese, candied watermelon rind, preserved camel humps from Persia…Groaning and sweating, they pile their tonnage up to the checker, see it packaged in a forest’s worth of paper bags and, the whole now reassembled as a tower of bags pyramided on another cart, they stagger off to their cars, drained of their wealth but filled with pride in their awesome capacity of consumption.At times, seeing such a customer trying to buy up the whole supermarket, one is tempted to say, “Come now, my good woman, you’ve had enough for the day.” Unfortunately, the ambience（气氛）of supermarkets does not encourage verbal exchanges. In this it is inferior to the saloon.Urban people, of course, are terribly scared nowadays. They may yearn for society, but it is risky to go around talking to strangers for a lot of reasons, one being that people are so accustomed not to have many human contacts that they are afraid they may find out they really prefer life that way.Whatever the reason, they go to the supermarket to be with people, but not to talk with people. The rule seems to be, you can look but you can’t speak. Ah, well most days there is a good bit to see. The other day in my own supermarket, for example, there was a woman who was sneakily （鬼鬼祟祟地）lifting the cardboard lids on Sara Lee frozen coffee cakes and peeking under, eyeball to coffee cake, to see if---what?Could she have misplaced something? Did she suspect that the contents were not as advertised? Whatever her purposes, she didn’t buy.Another woman was kneading（捏）a long package of white bread with her fingertips, rather like a doctor going over an abdomen for a cry of pain that might confirm appendicitis (阑尾炎). I had seen those silly women in the television commercial squeeze toilet paper, and so was prepared for almost anything, but this medical examination of the bread was startling.The woman, incidentally, did not buy. She left the store without a single purchase. This may have been because she looked at the “express checkout” line, saw that it would take forty-five minutes to pay for her bread and decided bread was not worth the wait.I suspect that woman who left empty-handed never intended to buy. I think she had simply become lonely sitting alone in her flat, or had begun to feel claustrophobic perhaps with her family, and had decided to go out to the supermarket and knead a loaf of white bread for the pure fun of feeling herself part of the great busy world.1.

(15%)I am honored and humbled to stand here, where so many of America's leaders have come before me, and so many will follow.We have a place, all of us, in a long story-a story we continue, but whose end we will not see. It is the story of a new world that became a friend and liberator of the old, a story of a slave-holding society that became a servant of freedom, the story of a power that went into the world to protect but not possess, to defend but not to conquer. It is the American story-a story of flawed and fallible people, united across the generations by grand and enduring ideals.The grandest of these ideals is an unfolding American promise that everyone belongs, that everyonedeserves a chance, that no insignificant person was ever born.Americans are called to enact this promise in our lives and in our laws. And though our nation has sometimes halted, and sometimes delayed, we must follow no other course.Through much of the last century, America's faith in freedom and democracy was a rock in a raging sea. Now it is a seed upon the wind, taking root in many nations.Our democratic faith is more than the creed of our country, it is the inborn hope of our humanity, an ideal we carry but do not own, a trust we bear and pass along. And even after nearly 225 years, we have a long way yet to travel.VI. Translate the underlined part of the following passage into English. (15%) 对于心的境界，我所能够给出的最高赞语就是：丰富的单纯。

在使⽤Flink1.11的时候写了个本地Test 运⾏的时候发现报错了，具体如下Exception in thread "main" ng.IllegalStateException: No ExecutorFactory found to execute the application.at org.apache.flink.core.execution.DefaultExecutorServiceLoader.getExecutorFactory(DefaultExecutorServiceLoader.java:84)at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.executeAsync(StreamExecutionEnvironment.java:1801) at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.java:1711)at org.apache.flink.streaming.api.environment.LocalStreamEnvironment.execute(LocalStreamEnvironment.java:74)at org.apache.flink.streaming.api.environment.StreamExecutionEnvironment.execute(StreamExecutionEnvironment.java:1697)at com.bigdata.testKafkaUpsert.main(testKafkaUpsert.java:54)查看Flink1.11 release⽂档发现Reversed dependency from flink-streaming-java to flink-client (FLINK-15090)Starting from Flink 1.11.0, the flink-streaming-java module does not have a dependency on flink-clients anymore.If your project was depending on this transitive dependency you now have to add flink-clients as an explicit dependency.从Flink 1.11.0 开始flink-streaming-java不再依赖flink-client需要单独引⽤，那么增加相应依赖即可解决<dependency><groupId>org.apache.flink</groupId><artifactId>flink-clients_${scala.binary.version}</artifactId><version>${flink.version}</version><scope>provided</scope></dependency>参考⽂档。
QuartzScheduler当任务中出现异常时的处理策略（JobExecutionExc。。。
QuartzScheduler当任务中出现异常时的处理策略（JobExecutionExc。
Quartz当JOB中出现异常时的处理策略正常情况下，如果当⼀个任务(job)的⽅法中出现异常时，Scheduler引擎不会处理这个异常，这个任务还是会按照触发器设定的时间正常触发！但是Scheduler引擎为我们提供了⼀个异常(JobExecutionExceptions),当任务出现异常时，我们将异常转换为JobExecutionExceptions异常抛出，从⽽可以控制调度引擎的操作。
⼀、⽴即重新执⾏该任务当任务中出现异常时，我们捕获它，然后转换为JobExecutionExceptions异常抛出，同时可以控制调度引擎⽴即重新执⾏这个任务(注意红⾊代码)。
try {int zero = 0;int calculation = 4815 / zero;}catch (Exception e) {_("--- Error in job!");JobExecutionException e2 =new JobExecutionException(e);// this job will refire immediatelye2.refireImmediately();throw e2;}⼆、取消所有与这个任务关联的触发器try {int zero = 0;int calculation = 4815 / zero;}catch (Exception e) {_("--- Error in job!");JobExecutionException e2 =new JobExecutionException(e);// Quartz will automatically unschedule// all triggers associated with this job// so that it does not run againe2.setUnscheduleAllTriggers(true);throw e2;}。
