我看网上很多人都这样写 但我反复试了几次 死活不行 麻烦大家帮忙看看
我的是spring mvc3.1.3

代码如下
java
@RequestMapping(value = "testRequestBody.do", method = RequestMethod.POST) public void testRequestBody(@RequestBody List<UserVO> users) throws UnsupportedEncodingException { System.out.println("in here"); System.out.println(users.size()); System.out.println("end"); }
用户对象类
public class UserVO { private String name; private String pwd; public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPwd() { return pwd; } public void setPwd(String pwd) { this.pwd = pwd; } public UserVO() { } public UserVO(String name, String pwd) { this.name = name; this.pwd = pwd; } }

javascript
var users = JSON.stringify([ {name: "user1", pwd: "123"}, {name: "user2", pwd: "123"} ]); alert(users); $.ajax({ type: "post", // 请求方式 url: "testRequestBody.do", //url地址 data:users, //数据 contentType: "application/json", dataType: "json", success: function (response, ifo) { alert("success"); }, error: function () { alert("error"); } })

chrome 后台错误 Failed to load resource: the server responded with a status of 415 (Unsupported Media Type)

问题补充：@RequestBody List<UserVO> users 如果将这里去掉
则可以成功访问到方法 说明ajax是能访问服务器的
只是在转换对象的时候出错了  但应该怎么写呢？
