なぜJerseyTestは400 Bad Requestを返す代わりにConstraintViolationExceptionをスローしますか？

Question

Jerseyバージョン2.23.2を使用しており、JerseyTestを使用して検証が失敗した場合の応答をテストする方法を理解できません。何らかの理由で、ConstraintViolationExceptionがProcessingExceptionにラップされ、400 Bad Requestが返されます。私はProcessingExceptionがスローされたことを確認するためにテストを修正することができましたが、本当にレスポンスをテストしたいと思います。 GrizzlyでJerseyTestを使わずにHelloResourceを実行すると、適切な400リクエストレスポンスが得られます。どのようにbadRequestResponse()テストを修正するための任意のアイデア？

javax.ws.rs.ProcessingException: 
Exception Description: Constraints violated on marshalled bean: 
example.BadRequestTest$Hello@456abb66 
-->Violated constraint on property name: "Name is a required field.". 
Internal Exception: javax.validation.ConstraintViolationException

Answer 1

これは、クライアント側の問題がある：

package example; 

import org.glassfish.jersey.server.ResourceConfig; 
import org.glassfish.jersey.server.ServerProperties; 
import org.glassfish.jersey.test.JerseyTest; 
import org.junit.Test; 

import javax.validation.Valid; 
import javax.validation.constraints.NotNull; 
import javax.ws.rs.POST; 
import javax.ws.rs.Path; 
import javax.ws.rs.client.Entity; 
import javax.ws.rs.core.Application; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 
import javax.xml.bind.annotation.XmlAccessType; 
import javax.xml.bind.annotation.XmlAccessorType; 

import static org.junit.Assert.assertEquals; 

public class BadRequestTest extends JerseyTest { 
    @XmlAccessorType(XmlAccessType.FIELD) 
    public static class Hello { 
     @NotNull(message = "Name is a required field.") 
     private final String name; 

     private Hello() { 
      this(null); 
     } 

     public Hello(String name) { 
      this.name = name; 
     } 

     public String getName() { 
      return name; 
     } 
    } 

    @Path("hello") 
    public static class HelloResource { 
     @POST 
     public String sayHelloToMe(@Valid Hello hello) { 
      return "Hello " + hello.getName() + "!"; 
     } 
    } 

    @Override 
    protected Application configure() { 
     return new ResourceConfig(HelloResource.class).property(ServerProperties.BV_SEND_ERROR_IN_RESPONSE, true); 
    } 

    /** Test OK Response. This Works!*/ 
    @Test 
    public void okResponse() { 
     Response response = target("hello") 
       .request(MediaType.TEXT_PLAIN) 
       .post(Entity.json(new Hello("Tiny Tim"))); 

     assertEquals(Response.Status.OK.getStatusCode(), response.getStatus()); 
     assertEquals("Hello Tiny Tim!", response.readEntity(String.class)); 
    } 

    /** Test Bad Request Response. This Fails! */ 
    @Test 
    public void badRequestResponse() { 
     Response response = target("hello") 
       .request(MediaType.TEXT_PLAIN) 
       .post(Entity.json(new Hello(null))); 

     assertEquals(Response.Status.BAD_REQUEST.getStatusCode(), response.getStatus()); 
    } 
} 

は、ここで私は取得しています例外です。 MOXyはデフォルトでBeanの検証を行います。したがって、クライアントでBeanの検証を取得しています。したがって、クライアントでエラーが発生しているため、リクエストは処理されません。文字列を送信するだけでこれをテストできます。

Entity.json("{}") 

エラーを取り除く必要があります。しかし、コメントで述べたようにBeanを使用する場合は、MOXyを使用してクライアント上でBeanの検証を無効にする必要があります

@Override 
protected void configureClient(final ClientConfig config) { 
    super.configureClient(config); 
    config.register(new MoxyJsonConfig() 
      .property(MarshallerProperties.BEAN_VALIDATION_MODE, 
         BeanValidationMode.NONE).resolver()); 
}
