JAVA读取properties文件

JAVA读取properties文件

test.properties

keykey=Oh.I get the value!

 测试类SuperPath.java

package com.test.superpath; 

import java.io.InputStream; 
import java.util.Properties; 

/**

*/ 
public class SuperPath { 

/** 
* 从配置文件取值 
* @param fileName 配置文件名 
* @return 从指定key得到的value 
*/ 
  public String getPara(String fileName) { 

     Properties prop = new Properties(); 
    try { 
      // ClassLoader cl = this.getClass().getClassLoader(); 
      // InputStream is = cl.getResourceAsStream(fileName); 
       InputStream is = this.getClass().getResourceAsStream(fileName); 
       prop.load(is); 
      if (is != null) 
         is.close(); 
     } catch (Exception e) { 
       System.out.println(e + "file " + fileName + " not found"); 
     } 
    /** 
     * 指定哪个key 
     */ 
    return prop.getProperty("keykey"); 
   } 

  public static void main(String[] args) { 
     SuperPath sp=new SuperPath(); 
     System.out.println(sp.getPara("test.properties")); 
   } 

}

 

输出结果:

Oh.I get the value!
