ajax传递参数 springmvc怎么接收

$("#test2").on("click",function(){

var id =1

var username="fangxin"

$.post("/mvc/client1/test2",{id:id,username:username,birthday:new Date()})

})；

Spring后台接收

@RequestMapping("/test2")

@ResponseBody

public void test2(User user){

System.out.println(user.getId())

System.out.println(user.getUsername())

System.out.println(user.getBirthday())

}

var codes=[1,2,3]//定义数组

$.ajax({

type: "POST", //用POST方式传输

dataType: "json", //数据格式:JSON

url: ..., //目标地址

traditional: true,

data: {

codes:codes,

},

error: function (XMLHttpRequest, textStatus, errorThrown) {...},

success: function (msg){...}

})

注意traditional: true不能少，

后台String[] codes接收参数，然后遍历取值，

for(int m=0m<codes.lengthm++){

String code=codes[m]

...

}
