Java替换第一个和最后一个字符串

1、测试类

package com.jeff.json; 
 
import com.alibaba.fastjson.JSONObject; 
 
public class JsonDemo1 {
   
     
 
	public static void main(String[] args) {
   
     
		String ret = "\"{\"success\":true,\"msg\":\"success\",\"data\":{}}\""; 
		System.out.println(ret); 
		if (ret.startsWith("\"")) {
   
     
			ret = replaceFirst(ret, "\"", ""); 
			System.out.println("去除前引号：" + ret); 
		} 
		if (ret.endsWith("\"")) {
   
     
			ret = replaceLast(ret, "\"", ""); 
			System.out.println("去除后引号：" + ret); 
		} 
		JSONObject result = JSONObject.parseObject(ret); 
		System.out.println(result); 
	} 
 
	private static String replaceFirst(String ret, String strToReplace, String replaceWithThis) {
   
     
 
		return ret.replaceFirst(strToReplace, replaceWithThis); 
	} 
 
	public static String replaceLast(String text, String strToReplace, String replaceWithThis) {
   
     
		return text.replaceFirst("(?s)" + strToReplace + "(?!.*?" + strToReplace + ")", replaceWithThis); 
	} 
 
} 
 

2、控制台
