Question

我试图通过代理调用webservice方法，但我收到一条错误消息：“目标类的子资源没有jax-rs注释：org.jboss.resteasy.core.ServerResponse”

这是我的服务器类

@Path("/authorizationCheck")
public class AuthorizationRestService implements AuthorizationService  {

  @Override
    @Path("/webserviceTest")
    public Response webserviceTest(){
    TestDTO  x = new TestDTO();
    x.setFieldOne("ffff");
    x.setFieldTwo("gggg");
    Response res = Response.ok(x).build();
    return res;


    }
}

使用像这样的界面

@Path("/authorizationCheck")
public interface AuthorizationService {

    @POST
    @Path("/webserviceTest")
    public Response webserviceTest();
}

并将我的返回对象包装在响应中

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class TestDTO {

    private String fieldOne;

    private String fieldTwo;

    public String getFieldOne() {
        return fieldOne;
    }

    public void setFieldOne(String fieldOne) {
        this.fieldOne = fieldOne;
    }

    public String getFieldTwo() {
        return fieldTwo;
    }

    public void setFieldTwo(String fieldTwo) {
        this.fieldTwo = fieldTwo;
    }



}

最后是我的客户端类

@Stateful
@Scope(ScopeType.CONVERSATION)
@Name("authorizationCheckService")
public class AuthorizationCheckService {

    public void testWebservice(){
        RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
        AuthorizationService  proxy = 
                ProxyFactory.create(AuthorizationService.class,
                        ApplicationConfig.WORKFLOWSERVER_URL + "services/authorizationCheck/webserviceTest");
        Response response =   proxy.webserviceTest();
        return;



    }
}

我在这里做错了，任何帮助都将不胜感激。

Answer 1

您有两个带有webserviceTest（）的注释，它们是@POST和@Path。

在实现的类中重复使用over ridden方法中的注释。这意味着将@POST注释添加到webserviceTest（）方法。

它应该工作了！

这就是为什么它没有工作......没有适当的注释来实现类。 Why java classes do not inherit annotations from implemented interfaces?

Answer 2

您可以删除实现类和具体方法上的@Path注释，并仅注释您的接口，如下所示：

public class AuthorizationRestService implements AuthorizationService  {

    @Override
    public Response webserviceTest(){
        TestDTO  x = new TestDTO();
        x.setFieldOne("ffff");
        x.setFieldTwo("gggg");
        Response res = Response.ok(x).build();
        return res;
    }
}

注意：请勿忘记界面方法上的@Produces来定义您的MIME类型，例如MediaType.APPLICATION_XML

@Path("/authorizationCheck")
public interface AuthorizationService {

    @POST
    @Path("/webserviceTest")
    @Produces(MediaType.APPLICATION_XML)
    public Response webserviceTest();
}

Answer 3

我改变了这个

@Path("/authorizationCheck")
public class AuthorizationRestService implements AuthorizationService  {

@Override
@Path("/webserviceTest")
@POST
@Produces(MediaType.APPLICATION_XML)
public Response webserviceTest(){
TestDTO  x = new TestDTO();
x.setFieldOne("ffff");
x.setFieldTwo("gggg");
Response res = Response.ok(x).build();
return res;


}
}

我的测试客户端不同

public class CustomerResourceTest
{
@Test
public void testCustomerResource() throws Exception
{
   URL postUrl = new URL("http://localhost:9095/authorizationCheck/webserviceTest");
   HttpURLConnection   connection = (HttpURLConnection) postUrl.openConnection();
      connection.setRequestMethod("POST");
      System.out.println("Content-Type: " + connection.getContentType());

      BufferedReader reader = new BufferedReader(new
              InputStreamReader(connection.getInputStream()));

      String line = reader.readLine();
      while (line != null)
      {
         System.out.println(line);
         line = reader.readLine();
      }
      Assert.assertEquals(HttpURLConnection.HTTP_OK, connection.getResponseCode());
      connection.disconnect();

   return;
}
}

它产生了输出

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><testDTO><fieldOne>ffff</fieldOne><fieldTwo>gggg</fieldTwo></testDTO>

还必须添加以下依赖

<dependency>
        <groupId>javax.xml.bind</groupId>
        <artifactId>jaxb-api</artifactId>
        <version>2.2.11</version>
    </dependency>
    <dependency>
        <groupId>org.jboss.resteasy</groupId>
        <artifactId>resteasy-jaxb-provider</artifactId>
        <version>2.2.0.GA</version>
    </dependency>

尝试了你的代码。

public void testCustomerResource() throws Exception
{
   RegisterBuiltin.register(ResteasyProviderFactory.getInstance());
   AuthorizationService  proxy = 
           ProxyFactory.create(AuthorizationService.class,"http://localhost:9095/");
   ClientResponse response = (ClientResponse) proxy.webserviceTest();
   String str = (String)response.getEntity(String.class);
   System.out.println(str);
   return;
}

生成相同的输出

<?xml version="1.0" encoding="UTF-8" standalone="yes"?><testDTO><fieldOne>ffff</fieldOne><fieldTwo>gggg</fieldTwo></testDTO>

注意我是如何创建代理的。我只有基本网址**http://localhost:9095/**。我没有提到资源 authorizationCheck / webserviceTest 。这与您编码的方式不同。

目标类的子资源没有jax-rs注释
