我是使用JAX-RS和学习RESTFul的新手。仅当我从JAX-RS客户端应用程序请求时,我才面临问题。从post插件可以正常工作。但是,当我用“ application / xml”更改@Consumes(“ myformat / xml”)时,它就会起作用。下面是代码。
MessageBodyReader:
package com.memorynotfound.jaxrs.chunked;
import java.io.IOException;
import java.io.InputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.Consumes;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyReader;
import javax.ws.rs.ext.Provider;
@Provider
@Consumes("myformat/xml")
public class UserMessageBodyReader implements MessageBodyReader<User> {
public boolean isReadable(Class<?> arg0, Type arg1, Annotation[] arg2, MediaType arg3) {
if (arg0.equals(User.class))
return true;
else
return false;
}
public User readFrom(Class<User> arg0, Type arg1, Annotation[] arg2, MediaType arg3,
MultivaluedMap<String, String> arg4, InputStream arg5) throws IOException, WebApplicationException {
return new User(1, "Jphn Doe");
}
}
资源:
package com.memorynotfound.jaxrs.chunked;
import javax.ws.rs.Consumes;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
@Path("/users")
public class UserResource {
@POST
@Consumes("myformat/xml")
public User getUser(User user) {
return user;
}
}
客户代码:
package com.restfulexample.client.messagebodyreader;
import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
public class MessageBodyReader {
public static void main(String[] args) {
Client client = ClientBuilder.newClient();
User user = new User(1, "Jphn Doe");
User postedUser = client.target("http://localhost:9090/message-body-reader/api/users").request("myformat/xml")
.post(Entity.xml(user), User.class);
System.out.println(postedUser.getId() + " " + postedUser.getName());
}
}
答案 0 :(得分:0)
使用以下代码找到了解决方案...
客户端客户端= ClientBuilder.newClient()。register(UserMessageBodyReader.class) .register(UserMessageBodyWriter.class);
我们必须向客户端注册MessageBodyReader和Writer。
