通过一个map替换字符串中指定的字符变量方法

package com.test;




import java.util.HashMap;

import java.util.Map;




public class StringFormat {




	public static String format(String input, Map<String, String> map) {

		// 遍历map,用value替换掉key

		for (Map.Entry<String, String> entry : map.entrySet()) {

			input = input.replace(entry.getKey(), entry.getValue());

		}

		return input;

	}




	public static void main(String[] args) {

		Map<String, String> map = new HashMap<String, String>();

		map.put("$1", "value1");

		map.put("$2", "value2");

		map.put("$3", "value3");

		System.out.println("结果:" + StringFormat.format("$1$2$3", map));

		// 结果:value1value2value3

	}
