내 게시물 요청은 저지에서 500 내부 서버 오류를 반환합니다.

Question

저지에서 데이터를 게시하려고하지만 모든 오류가 500 번 발생합니다. 내 GET 요청은 모두 정상적으로 작동합니다.

아래는 나의 클라이언트 코드입니다.

package main; 

import com.sun.jersey.api.client.Client; 
import com.sun.jersey.api.client.ClientResponse; 
import com.sun.jersey.api.client.WebResource; 
import com.sun.jersey.api.client.filter.HTTPBasicAuthFilter; 

public class MainClass { 

    public static void main(String[] args) { 


     try { 
      Client client = Client.create(); 
      client.addFilter(new HTTPBasicAuthFilter("admin", "admin")); 
      WebResource webResource = client 
       .resource("http://localhost:7307/mysite/rest_service/postdataclass/postData"); 

      String input = "{\"name\":\"Violent Soho\",\"last\":\"Jesus Stole My Girlfriend\"}"; 

      ClientResponse response = webResource.type("application/json") 
       .post(ClientResponse.class, input); 

      if (response.getStatus() != 200) { 
       throw new RuntimeException("Failed : HTTP error code : " 
        + response.getStatus()); 
      } 

      System.out.println("Output from Server .... \n"); 
      String output = response.getEntity(String.class); 
      System.out.println(output); 
     } catch (Exception e) { 
      // TODO: handle exception 
      e.printStackTrace(); 
     } 

    } 

} 

그리고 여기에 내가 POST 요청을 할 때 아래는 서버 로그 내 다른 클래스

package service.utils; 

import javax.ws.rs.Consumes; 
import javax.ws.rs.GET; 
import javax.ws.rs.POST; 
import javax.ws.rs.Path; 
import javax.ws.rs.PathParam; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 
import javax.ws.rs.core.Response; 
import beans.AASample; 

@Path("postdataclass") 
public class PostSample { 

    @GET 
    @Path("/sayHell") 
    public Response sayHell() { 

     return Response.status(Response.Status.OK).entity("Hell").build(); 
    } 

    @POST 
    @Path("/postData") 
    @Consumes(MediaType.APPLICATION_JSON) 
    public Response postData(AASample sample) { 

     return Response.status(Response.Status.OK).entity("Profile " + sample.toString()).build(); 
    } 

} 

그리고 내 AAClass

package beans; 

public class AASample { 
    private String name; 
    private String last; 
    public AASample(String name, String last) { 
     super(); 
     this.name = name; 
     this.last = last; 
    } 
    public AASample() { 
     super(); 
    } 
    public String getName() { 
     return name; 
    } 
    public void setName(String name) { 
     this.name = name; 
    } 
    public String getLast() { 
     return last; 
    } 
    public void setLast(String last) { 
     this.last = last; 
    } 
    @Override 
    public String toString() { 
     return "AASample [name=" + name + ", last=" + last + "]"; 
    } 



} 

입니다.

Answer 1

내 데이터를 수동으로 json 개체로 변환했습니다.

@POST 
@Path("/postData") 
@Consumes(MediaType.APPLICATION_JSON) 
public Response postData(String sample) { 

    AASample object = StringToObjectConverter.getObject(sample); 
    if(object != null){ 
     return Response.status(Response.Status.OK).entity("Object " + object.toString()).build(); 
    }else{ 
     return Response.status(Response.Status.OK).entity("We Failed Decoding :" + sample +":").build(); 
    } 

} 

StringToObjectConverter 클래스

package main 
import java.io.IOException; 

import org.codehaus.jackson.JsonGenerationException; 
import org.codehaus.jackson.map.JsonMappingException; 
import org.codehaus.jackson.map.ObjectMapper; 

import beans.AASample; 

public class StringToObjectConverter { 


    public static AASample getObject(String postedData) { 
     AASample aaSample = null; 
     ObjectMapper mapper = new ObjectMapper(); 
     try { 
      aaSample = mapper.readValue(postedData, AASample.class); 
     } catch (JsonGenerationException e) { 
      aaSample = null; 
     } catch (JsonMappingException e) { 
      aaSample = null; 
     } catch (IOException e) { 
      aaSample = null; 
     } 
     return aaSample; 
    } 


}
