J2EE_实验报告7_Spring的IOC

J2EE实验报告实验内容1功能描述1.1、掌握Spring框架的建立步骤；1.2、掌握Spring的Ioc注入方式：传值注入和构造注入；1.3、掌握Spring的静态工厂注入方式；1.4、掌握Spring的实例工厂注入方式。

2实验步骤2.1 搭建Spring 框架(0) 新建web project项目，项目名称自定义（我取名为EX_Ioc）；(1) 将spring需要的jar包拷贝到______下；（2）在src下新建applicationContext.xml文件<?xml version="1.0"encoding="UTF-8"?><beansxmlns="/schema/beans"xmlns:xsi="/2001/XMLSchema-instance"xmlns:p="/schema/p"xmlns:aop="/schema/aop"xsi:schemaLocation="/schema/bean s/schema/beans/spring-beans-3.0.xsd/schema/aop/schema/aop/spring-aop-3.0.xs d"></beans>2.2 注入普通类及属性（1）在src下新增包.xmut.first，在该包下新建类Person.java：Person.javapackage .xmut.first;public class Person {private String name;public void sayHello(){System.out.println("hello, i am " + name);}//省略get set 方法}（2）在applicationContext.xml文件中添加配置<!-- frist 配置简单类及属性 --><bean id="person"class="____"><property name="____"value="xmut"></property> </bean>（3）编写测试代码在src下新增包.xmut.test，在该包下新建类MyTest.java：package .xmut.test;import org.springframework.context.ApplicationContext;importorg.springframework.context.support.ClassPathXmlApplicationCon text;import .xmut.HelloSpring.app.frist.Person;public class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("______.xml");Person person = (______) apc.getBean("______");person.sayHello();}}（4）运行测试代码，查看结果。

2.3 配置类及使用bean--传值注入（1）在src下新增包.xmut.second，在该包下新建接口IPerson.java、IAxe.java和类Chinese.java、American.java、SteelAxe.java、Stone.javaIPerson.javapackage .xmut.second;public interface IPerson {public void userAxe();}IAxe.javapackage .xmut.second;public interface IAxe {public void chop();}Chinese.javapackage .xmut.second;public class Chinese implements IPerson {private IAxe axe;public void useAxe() {axe.chop();}}American.javapackage .xmut.second;public class American implements IPerson {private IAxe axe;public void useAxe() {axe.chop();}}SteelAxe.javapackage .xmut.second;public class SteelAxe implements IAxe {public void chop() {System.out.println("steelAxe is quick");}StoneAxe.javapackage .xmut.second;public class StoneAxe implements IAxe {public void chop() {System.out.println("stoneAxe is slow");}}（2）在applicationContext.xml文件中添加配置<!-- second 配置类及使用bean --><bean id="stoneAxe"class="________"></bean><bean id="steelAxe"class="________"></bean><bean id="chinese"class="________"><property name="axe"ref="________"></property> </bean><bean id="american"class="________"><property name="axe"ref="stoneAxe"></property> </bean>（3）编写测试代码修改类MyTest.java：package .xmut.test;import org.springframework.context.ApplicationContext;importorg.springframework.context.support.ClassPathXmlApplicationCon text;public class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("______.xml");//second 配置类及使用beanChinese chinese = (Chinese) apc.getBean("____");eAxe();American american = (American) apc.getBean("____");eAxe();}}（4）运行测试代码，查看结果。

2.3 配置类及使用bean--构造注入（1）在包.xmut.second下，新建类 France.javaFrance.javapackage .xmut.second;public class France implements IPerson {private IAxe axe;private IAxe axe2;private String name;public France() {}public France(IAxe axe,IAxe axe2,String name) { this.axe = axe;this.axe2 = axe2; = name;}public void useAxe() {axe.chop();axe2.chop();System.out.println(name);}}（2）在applicationContext.xml文件中添加配置<bean id="france"class="______"><constructor-arg ref="____"></constructor-arg><constructor-arg ref="____"></constructor-arg><constructor-arg value="____"></constructor-arg> </bean>（3）编写测试代码修改类MyTest.java：package .xmut.test;import org.springframework.context.ApplicationContext;importorg.springframework.context.support.ClassPathXmlApplicationCon text;public class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("______.xml");//构造注入France france = (France) apc.getBean("_____");eAxe();}}（4）运行测试代码，查看结果。

2.4 静态工厂注入（1）在src下新增包.xmut.third，在该包下新建类Dog.java、Cat.java、Factory.java和接口IBeing.javaIBeing.javapackage .xmut.third;public interface IBeing {public void ___________;}Dog.javapackage .xmut.third;public interface Dog implements IBeing {private String name;public void sayHello(){System.out.println("Hello,i am dog!My name is:"+name);}}Cat.javapackage .xmut.third;public interface Cat implements IBeing {private String name;public void sayHello(){System.out.println("Hello,i am cat!My name is:"+name);}}Factory.javapackage .xmut.third;public class Factory {public static IBeing getBeing(String type){if(type.equalsIgnoreCase("____")){return new Dog();}else {return new Cat();}}}（2）在applicationContext.xml文件中添加配置<!-- 静态工厂生成bean --><bean id="dog"class="____"factory-method="getBeing"> <constructor-arg value="dog"></constructor-arg><property name="name"value="____"></property> </bean><bean id="cat"class="____"factory-method="getBeing"> <constructor-arg value="cat"></constructor-arg><property name="name"value="____"></property> </bean>（3）编写测试代码修改类MyTest.java：package .xmut.test;import org.springframework.context.ApplicationContext;importorg.springframework.context.support.ClassPathXmlApplicationCon text;public class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("______.xml");//静态工厂生成beanDog dog = (Dog) apc.getBean("____");dog.sayHello();Cat cat = (Cat) apc.getBean("____");cat.sayHello();}}（4）运行测试代码，查看结果。
