ExceptionMapper在JerseyTest框架中不工作

我爲特定對象製作了RESTFUL-API，並使用javax.validation.Constraints進行了驗證，當我執行應用程序時，它按預期方式工作，並且ExceptionMapper類已正確執行，但當我嘗試使用自動化測試JerseyFramework不執行或處理ExceptionMapper。所以它適用於應用程序，但不是當我測試它時。ExceptionMapper在JerseyTest框架中不工作

主類，啓動應用

package com.carlos.zerga.server; 
public class App { 
    public static void main(String[] args) throws Exception { 

     AppResourceConfig config = new AppResourceConfig(); 
     ServletHolder jerseyServlet 
       = new ServletHolder(new ServletContainer(config)); 

     Server server = new Server(8081); 
     ServletContextHandler context 
       = new ServletContextHandler(server, "/"); 

     context.addServlet(jerseyServlet, "/*"); 

     server.start(); 
     server.join(); 
    } 
}

ResourceConfig爲App

package com.carlos.zerga.server; 
public class AppResourceConfig extends ResourceConfig{ 

    public AppResourceConfig() { 
     register(new PropertiesBinder()); 
     register(EntityValidationExceptionMapper.class); 
     packages(true,"com.carlos.zerga.properties"); 
    } 
}

ExceptionMapper爲ValidationExceptions

package com.carlos.zerga.properties.presentation.handler; 
@Provider 
public class EntityValidationExceptionMapper implements  
ExceptionMapper<BeanValidationException> { 

    public Response toResponse(BeanValidationException e) { 

     return Response.status(200). 
       type(MediaType.APPLICATION_JSON_TYPE). 
       entity(buildResponse((ConstraintViolationException) e.getInternalException())). 
       build(); 
    } 
    private ExceptionResponse buildResponse(ConstraintViolationException e) 
    { 
     ArrayList<String> messages = new ArrayList<String>(); 
     for(ConstraintViolation constraintViolation:e.getConstraintViolations()) 
     { 
      messages.add(constraintViolation.getMessage()); 
     } 
     return new ExceptionResponse(200, messages,e.getClass().getSimpleName()); 
    } 

}

種源類

package com.carlos.zerga.properties.presentation; 
@Path("property") 
public class PropertiesApiResource { 

    @POST 
    @Path("new") 
    @Consumes(MediaType.APPLICATION_JSON) 
    @Produces(MediaType.APPLICATION_JSON) 
    public Property createProperty(Property property) 
    { 
     return property; 
    } 
    //LOT OF OTHER ROUTES 
    ...... 
}

測試用例

package com.carlos.zerga.test.properties.presentation; 

@RunWith(DataProviderRunner.class) 
public class PropertiesApiResourceTest extends JerseyTest { 

    @Override 
    protected Application configure() { 

     return new ResourceConfig() 
      .register(new PropertiesBinder()) 
      .register(new EntityValidationExceptionMapper()) 
      .register(new ConstraintValidationException()) 
      .packages(true,"com.carlos.zerga.properties"); 
    } 
    //Here comes the error 
    @Test 
    @UseDataProvider("provideInvalidPropertiesPSR_PA") 
    public void testInValidPropertyCreation(Property property) 
    { 
     Response response=target("property/new").request(MediaType.APPLICATION_JSON).method("POST",Entity.json(property)); 
     assertEquals(response.getMediaType(),MediaType.APPLICATION_JSON_TYPE); 
     String exceptionResponse=response.readEntity(String.class); 
     System.out.print(exceptionResponse); 
    }

當我被郵遞員送它返回我什麼，我想：

{"errorCode":200,"errors":["Bathroom : Amount bathrooms can't be empty"],"errorDescription":"ConstraintViolationException"}

但是當我運行測試返回我：

如果在堆棧跟蹤仔細看，你會看到這個錯誤實際上發生在客戶端，甚至在請求到達服務器之前。原因是您使用的是使用JAXB的MOXy，並且默認情況下啓用了JAXB bean驗證。您可以在堆棧跟蹤中看到JAXBBeanValidator正在被調用，並且它發生在實體的客戶端編組上。

有幾個解決方案：

  • 配置莫西禁用Bean驗證
  • 不要使用莫西

配置莫西禁用Bean驗證

配置MOXy，你可以使用MoxyJsonConfig。您應該在服務器端實際執行此操作，以免在服務器上進行雙重驗證。 Jersey提供的bean驗證與MOXy提供的不同。

在Test.java

@Override 
public void configureClient(ClientConfig config) { 
    config.register(new MoxyJsonConfig().setFormattedOutput(true) 
      .property(MarshallerProperties.BEAN_VALIDATION_MODE, BeanValidationMode.NONE) 
      .resolver()); 
}

的configureClient方法是在JerseyTest，您可以覆蓋配置Client的方法。您也可以在服務器端註冊同樣的MoxyJsonConfig和ResourceConfig。

不要使用莫西

我的解決辦法是剛剛擺脫莫西，並用傑克遜來代替。只要改變以下依賴於傑克遜在它下面

<!-- remove this --> 
<dependency> 
    <groupId>org.glassfish.jersey.media</groupId> 
    <artifactId>jersey-media-moxy</artifactId> 
    <version>${jersey.version}</version> 
</dependency> 
<!-- use this --> 
<dependency> 
    <groupId>org.glassfish.jersey.media</groupId> 
    <artifactId>jersey-media-json-jackson</artifactId> 
    <version>${jersey.version}</version> 
</dependency>

，並添加@Valid標籤：

Resource.java

...... MORE ROUTES 
@POST 
@Path("new") 
@Consumes(MediaType.APPLICATION_JSON) 
@Produces(MediaType.APPLICATION_JSON) 
public Property createProperty(@Valid Property property){ 
    return property; 
} 
...... MORE ROUTES

你不會傑克遜有這個問題，因爲傑克遜沒有做任何bean驗證。除了這個問題，我個人的觀點是傑克遜無論如何都只是一個更好的JSON整體庫。

注：如果您關閉莫西驗證（無論是通過配置或通過使用傑克遜），你將不再追趕一輛BeanValidationException（這是一個莫西）類，而是可以直接抓到ConstraintViolationException 。
