Spring最简单构建一个后台{msg:"登录成功",code:200,data:null}

一、简介

{msg:"登录成功",code:200,data:null}

二、两种请求

如果严格msg code data也带""

@RestController
@RequestMapping("/acountmanage")
public class UserCRUDController {

    /**
     * args:http://10.9.240.9:8088/api/admin/users?realname=&page=1&rows=1
     * @return
     */
    @ResponseBody
    @CrossOrigin
    @RequestMapping("/users")
    public String adminUsers(){
        //return ""{"msg":"登录成功","code":200,"data":null"}";
        String msg="{msg:"+""登录成功""+","+"code:200"+","+"data:"+"null}";
        return msg;
    }
}
