在spring mvc 傳遞簡單物件時候，是比較簡單的，

但是，在傳遞List 等，集合時，初學者，可能有點麻煩，

上面是我，解決各種問題．所需啊喲的blg

其中，前兩篇，可以解決大部問題，

最後，一篇，可以解決，全部問題

，接下來，我描述下我的問題

這是我car 物件的屬性，其中有兩個　SET  集合

https://gitee.com/echo_yi/cars/blob/master/src/main/java/com/org/cars/domain/Car.java

對於這個問題，前段採用ｊｓｏｎ　傳輸，但是，注意格式

jQuery("form").serialize(); //"username=&password="    String
jQuery("form").serializeArray(); //[{name:"username",value:""},{name:"password",value:""}]  shuzu
jQuery("form").serializeObject(); //{username:"",password:""}  
JSON.stringify(jsondata)

$.toJSON(customerArray), 

要理解，每一種的狀態，之前，我直接就是直接序列　　serialize（），導致出錯

這是我的　ｊｓ

$(document).ready(function(){
    submitUserList_3();
function submitUserList_3() {
        var car ={ "id" : 1, "name" : "2018款 730Li 領先型 M運動套裝", "price" : 28.88, "brand" : "賓士", "model" : "7系", "mileage" : 11.4, "vehicleOfAge"

$.ajax({
            url: "/twoone",
type: "POST",
contentType : 'application/json;charset=utf-8', //設定請求頭資訊
dataType:"json",
//data: JSON.stringify(customerArray),    //將Json物件序列化成Json字串，JSON.stringify()原生態方法
// data: $.toJSON(customerArray),            //將Json物件序列化成Json字串，toJSON()需要引用jquery.json.min.js
            // data:$("#put").serialize(),
            // data:"model="+ddd,
data:JSON.stringify(car),
success: function(data){
                console.log(data);
console.log($("#put").serialize());
console.log(JSON.stringify(car));
},
error: function(res){
                // alert(res.responseText);
console.log(res.responseText);
}
        });
}

});

其中，對於car 物件的資料，我是採用，先從後臺輸出一個＠Responsbody car,

直接運用　谷歌的postman 獲取資料，

然後放在js 裡面(因為對js 不熟，只好採用簡單的方法)

這是我的controller

    @PostMapping(value="/twoone",produces = MediaType.APPLICATION_JSON_VALUE)
//    @Time
//    @RequestMapping(value = "/twoone")
@ResponseBody
public Car u(@RequestBody Car car){
        System.out.println("-----------------");
System.out.println(car.getName());
//        return carRepository.findOne(1);
return car;
}

特別是

@PostMapping(value="/twoone",produces = MediaType.APPLICATION_JSON_VALUE)

宣告檔案，這個特別重要

，問題，解決

建議看下orgjson
