Spring_mvc 客户端采用ajax请求向服务器端传递json数据，利用@requestbody实现集合映射。
后端采用@requestbody String可以正常接收，但@requestbody List<实体类>出现错误，前端抓包出现 http 415错误，
前端代码：
<script>
//发送ajax请求
var userList = new Array();
userList.push({username:"zhangsan","age":18});
userList.push({username:"lisi",age:28});
$.ajax({
type:"POST",
url:"${pageContext.request.contextPath}/user/quick5",
data:JSON.stringify(userList),
contentType:"application/json;charset=utf-8"
});
</script>
前端抓包情况：
后端代码：
@RequestMapping(value="/quick5")
@ResponseBody
public void save5(@RequestBody List<User> list) throws IOException {
System.out.println(list.toString());
return;
}
User类：
public class User {
@JsonProperty(value="username" )
private String username;
@JsonProperty(value="age" )
private int age;
public User(){}
public User(String username,int age){
this.username = username;
this.age = age;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String toString() {
return "User{" +
"username='" + username + '\'' +
", age=" + age +
'}';
}
}
已测试点：加了Jackson依赖包；spring-mvc加了 mvc:default-servlet-handler/；前端请求的数据是json类型
