Jersey Method not allowed 405
提问by Ritesh
I am new to the rest services. I am trying to create a service that accepts json string from a client. I am getting 405 error when I am calling this service using JQuery. Below is the Java code for ws:
我是其他服务的新手。我正在尝试创建一个接受来自客户端的 json 字符串的服务。使用 JQuery 调用此服务时出现 405 错误。下面是 ws 的 Java 代码：
@POST
@Path("logevent")
@Consumes(MediaType.APPLICATION_JSON)
public boolean logEvent(String obj)
{
System.out.println(obj);
return true;
}
and
和
@Path("getdata")
@GET
public String getData()
{
return "Hello";
}
and jQuery code for posting the JSON is:
用于发布 JSON 的 jQuery 代码是：
var json ="{\"userName\":\"testtest\"}";
var json_data = JSON.stringify(json);
$.ajax({
type: "POST",
url: "http://localhost:8080/log/log/logevent",
// The key needs to match your method's input parameter (case-sensitive).
data: json_data,
contentType: "application/json",
dataType: "json",
success: function(data){alert(data);},
failure: function(errMsg) {
alert(errMsg);
}
What is going wrong? The post is not working, however when I hit the get using the URL http://<serverip>/log/log/getdataI get the response.
出了什么问题？该帖子不起作用，但是当我使用 URL 点击 get 时，http://<serverip>/log/log/getdata我得到了响应。

JSON MessageBodyReaders are able to unmarshal JSON stream into a JAXB bean (or POJO) but not into a String. Create a JAXB bean like:
JSONMessageBodyReader能够将 JSON 流解组为 JAXB bean（或 POJO），但不能解组为 String。创建一个 JAXB bean，如：
@XmlRootElement
public class User {
private String userName;
public String getUserName() {
return userName;
}
public void setUserName(final String userName) {
this.userName = userName;
}
}
and change your POSTresource method to:
并将您的POST资源方法更改为：
@POST
@Path("logevent")
@Consumes(MediaType.APPLICATION_JSON)
public boolean logEvent(User obj) {}

First be sure that the path is /log/log/logevent
首先确定路径是 /log/log/logevent
Then try changing the request/reponse type:
然后尝试更改请求/响应类型：
You should use application/json;charset=UTF-8(W3C XHR spec), moreover your webservice doesn't respond with JSON but ouptut a boolean, maybe you should change the response type.
您应该使用application/json;charset=UTF-8（W3C XHR 规范），而且您的网络服务不响应 JSON 而是输出一个布尔值，也许您应该更改响应类型。
For example with UTF-8:
例如使用 UTF-8：
JAX-RS
JAX-RS
@Consumes("application/json;charset=UTF-8")
jQuery
jQuery
contentType:"application/json;charset=UTF-8"
