springmvc 接受json參數的坑

 

構造json數據時候js對象中的值 一定要用 "" 雙引號，不能用單引號，因為轉成字符串后，到后台進行解析時，因為java認為單引號是單字符 ，轉不成對應的字符串，所以會報錯！

如下正確：

function insertByEntity() {
        var url = "/tuser/insertByEntity";
        var entity = {
            nickname: "nickname",
            realname: "realname",
            username: "username",
            userpass: "userpass",
            age: "age",
            sex: "sex",
            tel: "tle"
        };
        $.ajax(url, {
            type: 'POST',
            dataType: 'json',
            data: JSON.stringify(entity),
            beforeSend: function (xhr) {
                xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
            },
            success: function (data) {
                console.log(data);
            }
        });
    }

 

后台接收

@RequestMapping(value = "insertByEntity",
            method = RequestMethod.POST,
            consumes = MediaType.APPLICATION_JSON_UTF8_VALUE, //application/json;charset=UTF-8
produces = MediaType.APPLICATION_JSON_UTF8_VALUE) public RetJson insert(@RequestBody TUser entity) {}

application/json;charset=UTF-8
