用阿里的fastJson.jar进行list转成json字符串

package com.zcwSpringBoot.zcw.controller;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONArray;
import com.zcwSpringBoot.zcw.entiy.User;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.util.ArrayList;
import java.util.List;

/**
 * @author zhaocunwei
 * @ClassName: ListTOJSONController
 * @Description: TODO
 * @date 2019/11/13 11:24
 */
@RestController
public class ListTOJSONController {
    @RequestMapping("/listToJson")
    public String getListToJson(){

        User user = new User();
        user.setAge(10);
        user.setName("测试");
        user.setId(1);
        List<User> userList = new ArrayList<>();
        userList.add(user);
        return JSON.toJSON(userList).toString();
    }
}

测试结果：
