读取属性文件的方式

package com.yunda.test;

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

public class ReadProp {

public static void main(String []arg){
getPropertyByName2("messages.properties", "李四");
}

// 方法一：通过java.util.ResourceBundle读取资源属性文件
public static String getPropertyByName(String path, String name){
String result = "";

try {
// 方法一：通过java.util.ResourceBundle读取资源属性文件
result = java.util.ResourceBundle.getBundle(path).getString(name);
System.out.println("name:" + result);
} catch (Exception e) {
e.printStackTrace();
System.out.println("getPropertyByName error:" + name);
}
return result;
}

// 方法二：通过类加载目录getClassLoader()加载属性文件
public static String getPropertyByName2(String path, String name) {
String result = "";

// 方法二：通过类加载目录getClassLoader()加载属性文件
InputStream in = ReadProp.class.getClassLoader()
.getResourceAsStream(path);
// InputStream in =
// this.getClass().getClassLoader().getResourceAsStream("mailServer.properties");

// 注：Object.class.getResourceAsStream在action中调用报错，在普通java工程中可用
// InputStream in =
// Object.class.getResourceAsStream("/mailServer.properties");
Properties prop = new Properties();
try {
prop.load(in);
result = prop.getProperty(name).trim();
System.out.println("name:" + result);
} catch (IOException e) {
System.out.println("读取配置文件出错");
e.printStackTrace();
}
return result;
}
}
