java读取properties文件的方法

java 没用spring时 读取properties文件的方法：

 

public static void main(String[] args)  throws Exception{Properties pro = new Properties();/*InputStream is=new FileInputStream("src/config/test.properties");pro.load(is);is.close();String sid = pro.getProperty("sex");System.out.println(sid);pro.setProperty("tt", "vvtest2");pro.store(new FileOutputStream(new File("src/config/test.properties")), "test");*/pro.load(new FileReader(new File("src/config/test.properties")));System.out.println(pro.getProperty("mingzi"));pro.setProperty("zhan", "测试写入2");pro.store(new FileWriter(new File("src/config/test.properties")), "tt comment");}
