Spring Boot中JSON參數傳遞,后台實體接受問題

1、json參數為json字符串

var data = {
    name: '超管不是11',
    password: '123456'
};
$.ajax({
    type:"post",
    url: url,
    data: JSON.stringify(data),//這里格式為JSON字符串
    dataType: 'json',//返回數據類型
    contentType:"application/json;charset=utf-8",//這里注明傳遞參數類型為JSON字符串
    success: function (rs) {
        console.log(rs);
    }
});

@RequestMapping(value = "/login")
//后台需要加上@RequestBody 
public Result login(@RequestBody User user){
    System.out.println(user);
    return ResultUtil.success(ResultEnum.SUCCESS, null);
}

2、JSON參數為JSON對象

var data = {
    name: '超管不是11',
    password: '123456'
};
$.ajax({
    type:"post",
    url: url,
    data: {
        name: '超管不是11',//或者 "name": "xxx"
        password: '123456'//     "password": "xxx"
    },//這里格式為JSON對象
    dataType: 'json',//返回數據類型
    //contentType:"application/json;charset=utf-8",//這里需要注釋掉
    success: function (rs) {
        console.log(rs);
    }
});

@RequestMapping(value = "/login")
//public Result login(@RequestBody User user){
//    System.out.println(user);
//    return ResultUtil.success(ResultEnum.SUCCESS, null);
//}
//后台需要去掉@RequestBody, 必須去掉
public Result login(User user){
    System.out.println(user);
    return ResultUtil.success(ResultEnum.SUCCESS, null);
}
