Properties 转换成Map

对于Properties 转换成Map 的问题:

第一时间想到的肯定有以下:
1.  迭代出来  再 put 到 map 中去;
2. commons 是否有工具类 ;
可是 由于 Properties  实现了Map 接口,  所以有最最简单的 ,强制转换:
package com.feilong.example.util;

import java.util.Properties;
import java.util.Map;
import java.util.HashMap;
import java.util.Set; public class PropertiesToMap {
public static void main(String[] args) { Properties properties = new Properties(); properties.setProperty("StrictHostKeyChecking", "no");
properties.setProperty("app.version", "1.0"); // Create a new HashMap and pass an instance of Properties. Properties
// is an implementation of a Map which keys and values stored as in a string.
Map<String, String> map = new HashMap<String, String>((Map) properties); // Get the entry set of the Map and print it out. Set propertySet = map.entrySet();
for (Object o : propertySet) {
Map.Entry entry = (Map.Entry) o;
System.out.printf("%s = %s%n", entry.getKey(), entry.getValue());
}
}
}

对于**.properties文件中数据的读取感觉很好用。
