读写properties配置文件时带上注释

Java使用jdk自带的类操作properties配置文件，特别是更改文件后会把注释全部删掉，再读时会不知道配置是什么意思，下面这个类是我自己写的不删除注释操作properties的类。

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileOutputStream;

import java.io.IOException;

import java.io.InputStream;

import java.io.OutputStreamWriter;

import java.io.Reader;

import java.io.Writer;

import java.util.Date;

import java.util.HashMap;

import java.util.Iterator;

import java.util.LinkedHashMap;

import java.util.Map;

import java.util.Properties;

import java.util.Set;

/**

* 读取Properties配置文件，同时读出注释。注释在jdk源方法的LineReader中忽略，

*

* 此处改造LineReader,并添加存放的变量map

*

* 同时新加了getPropertyAndComment(key)方法，返回的字符串：如果有注释则为:值#注释，如果无注释，则为:值

*

* 写入Properties方法是直接从网上下载的方法
