org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException：找不到媒體的MessageBodyWriter

即使我在maven中添加了媒體moxy，我得到了org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException。我正在使用tomcat 8.5，我仍然不知道爲什麼我得到這個異常。我正在嘗試使用@valid註釋來驗證實體。org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException：找不到媒體的MessageBodyWriter

這是我的異常映射

import java.util.ArrayList; 
import java.util.List; 

import javax.validation.ConstraintViolation; 
import javax.validation.ConstraintViolationException; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 
import javax.ws.rs.ext.ExceptionMapper; 
import javax.ws.rs.ext.Provider; 

import com.seriesonline.app.seriestv.models.Errors; 

@Provider 
public class BeanValidationExceptionMapper implements ExceptionMapper<ConstraintViolationException> { 

    @Override 
    public Response toResponse(ConstraintViolationException ex) { 
     System.out.println("*** BeanValidationExceptionMapper ***"); 
     List<Errors> errors = new ArrayList<>(); 

     for (ConstraintViolation<?> cv : ex.getConstraintViolations()) { 
      Errors error = new Errors(); 
      error.setDescription("Description"); 
      error.setErrorMessage(cv.getMessage()); 
      error.setStatusCode(400); 
      errors.add(error); 
     } 

     return Response.status(400).entity(errors).type(MediaType.APPLICATION_JSON).build();// Response.status(400).entity(errors).type(MediaType.APPLICATION_JSON).build(); 
    } 

}

Maven的

     <dependency> 
      <groupId>org.glassfish.jersey.media</groupId>

感謝大家的時間......我希望我能解決這個問題。

固定的，這似乎是一種錯誤或類似的東西嗎？它有點像是如果它不能解析一個ArrayList到JSON，嗯，如果它是錯誤對象，只是一個對象，它工作正常，但問題出現時，它是一個對象的數組列表，它看起來像實體（對象）方法無法將實體解析爲JSON，所以我只是... Gson gson = new Gson（）; \t \t \t \t String JSON = gson.toJson（errors）; \t \t \t \t System.out.println（JSON）; \t \t return Response.status（400）.entity（JSON）.type（MediaType.APPLICATION_JSON）.build（）; –

隨着媒體MOXY ...

GenericEntity <List<MyClass>> g = new GenericEntity <List<MyClass>>(myList){};... return Response.status(400).entity(g).type(MediaType.APPLICATION‌_‌JSON).build();
