无法在REST/JERSEY中调用@DELETE Web服务 [英] Not able to invoke an @DELETE web service in REST/JERSEY

问题描述

我正在使用Jersey框架(JAX-RS实现)来构建RESTful Web服务.

I am using Jersey Framework (JAX-RS implementation) for building RESTful Web Services.

我无法使用@DELETE REST方法，因为当我尝试调用它时会抛出异常.以下@DELETE方法用于删除Employee:

I'm not able to use the @DELETE REST method, since its throwing an exception when I try to invoke it.The following @DELETE method is used to delete an Employee:

@Path("/employees")
public class EmpResource {

@DELETE
@Consumes(MediaType.APPLICATION_JSON)
public Response deleteEmployee(JAXBElement<String> r) throws ClassNotFoundException, SQLException {

    String name = r.getValue();
    String response = DAOaccess.deleteEmp(name);
    return Response.noContent().build();    

}

我正在使用以下代码块来调用服务:

And I'm using the following block of code to invoke the service:

Client client = Client.create();
WebResource webResource = client.resource("http://localhost:8080/RestApp/sample/employees");
String input = "{\"name\":\"John\"}";
ClientResponse response = webResource.type(MediaType.APPLICATION_JSON).delete(ClientResponse.class,input);

运行客户端时，它将引发以下异常:

When I run my client, it throws the following exception:

Exception in thread "main" com.sun.jersey.api.client.ClientHandlerException: java.net.ProtocolException: HTTP method DELETE doesn't support output
at com.sun.jersey.client.urlconnection.URLConnectionClientHandler.handle(URLConnectionClientHandler.java:151)
at com.sun.jersey.api.client.Client.handle(Client.java:648)
at com.sun.jersey.api.client.WebResource.handle(WebResource.java:680)
at com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74)
at com.sun.jersey.api.client.WebResource$Builder.delete(WebResource.java:599)

如果有人可以指导我解决问题，那就太好了

It would be great if someone could guide me on how to resolve it?

推荐答案

对我来说，它有助于从客户端上的delete()方法中删除输入参数

For me it helped to remove input parameter from delete() method on client

ClientResponse response = webResource.type(MediaType.APPLICATION_JSON).delete(ClientResponse.class);

并通过@pathParam发送:

and send it over @pathParam instead:

public String delete(@PathParam("input") String input){...}
