Spring最簡單構建一個后台{msg:"登錄成功",code:200,data:null}

一、簡介

{msg:"登錄成功",code:200,data:null}

二、兩種請求

如果嚴格msg code data也帶""

@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\":\"登錄成功\",\"code\":200,\"data\":null\"}";
        String msg="{msg:"+"\"登錄成功\""+","+"code:200"+","+"data:"+"null}";
        return msg;
    }
}
