一、文件样式：

二、config.default.properties中的内容：

weightpath=D:/harrypotter/xml/weight.xml<br /> dicpath=D:/harrypotter/xml/dictionary.xml<br /> dictionarypath=D:/harrypotter/cpv_dataset<br /> CHANGEPI=1<br /> CHANGEPN=1<br /> CHANGEPM=1<br /> CHANGEPIC=1<br /> CHANGEPIP=1<br /> name=zhujiadun 

三、操作代码

package com.taobao.jifeng.properties;<br /> import java.io.IOException;<br /> import java.io.InputStream;<br /> import java.util.Properties;<br /> public class TestProperties {<br /> public static void main(String[] args) {<br /> Properties properties = new Properties();<br /> InputStream is = null;<br /> is = TestProperties.class.getResourceAsStream("/com/taobao/jifeng/properties/config.default.properties");<br /> try {<br /> properties.load(is);<br /> String key = "name";<br /> System.out.println(TestProperties.getValue(properties, key));</p> <p> } catch (IOException e) {<br /> // TODO Auto-generated catch block<br /> e.printStackTrace();<br /> }<br /> }</p> <p> public static String getValue(Properties properties,String key)<br /> { </p> <p> if(properties.containsKey(key))<br /> {<br /> String value = properties.getProperty(key);<br /> return value;<br /> }<br /> else<br /> {<br /> return "";<br /> }<br /> }</p> <p> public static void clear(Properties properties)<br /> {<br /> properties.clear();<br /> } </p> <p> public static void setValue(Properties properties,String key,String value)<br /> {<br /> properties.setProperty(key,value);<br /> }<br /> }<br />  

四、输出结果：
