Spring接收List泛型对象参数

 前端

参数必须是数组累着

传入data时，转换 JSON.stringify(testList)

headers必须有属性

Accept': 'application/json',

'Content-Type': 'application/json'

var testList=[];
var user={};
user.id=1;
user.name='jack';
testList.push(user);
var user2={};
user2.id=2;
user2.name='tom';
testList.push(user2);
$.ajax({// headers必须添加，否则会报415错误headers: {'Accept': 'application/json','Content-Type': 'application/json'},type: 'POST',dataType: "json", //表示返回值类型，不必须data: JSON.stringify(testList),url: '/test/postList',success: function(){alert('success');}});

 后台

参数前面必须有注解 @RequestBody

@RequestMapping("/postList")@ResponseBodypublic String postList(@RequestBody List<TestL> testL){System.out.println(testL);return null;}

public class TestL {private Integer id;private String name;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}
}
