Question

有没有办法在500错误的情况下获取REST WS PUT请求中收到的原始JSON对象？

这是我的WS界面：

public interface VehicleConnectedMileageApi {
    public Response updateConnectedVehiclemileage(@ApiParam(value = "vehicle" ,required=true ) Vehicle vehicle)
  throws NotFoundException;
}

在我的application-context xml文件中，我使用以下命令来定义WS：

<!-- For VehicleConnectedMileage  -->
<jaxrs:server id="VehicleConnectedMileageREST" address="/mileageManagement">
    <jaxrs:serviceBeans>
        <ref bean="VehicleConnectedMileageApiImpl" />
    </jaxrs:serviceBeans>

    <jaxrs:providers>
        <bean class="com.europcar.gwy.fleet.utils.error.RuntimeExceptionMapperHandler" />
        <bean class="com.europcar.gwy.fleet.utils.error.MappingDataExceptionMapper" />
        <bean id="jacksonObjectMapperProvider" class="com.europcar.gwy.fleet.utils.providers.JacksonObjectMapperProvider" />
        <bean id="dateParameterConverterProvider" class="com.europcar.gwy.fleet.utils.providers.DateParamConverterProvider" />
        <bean id="jacksonProvider" class="org.codehaus.jackson.jaxrs.JacksonJsonProvider" />
    </jaxrs:providers>

</jaxrs:server>

但是在上面的那些提供者和映射器中，无法访问第一次收到的Vehicle对象。

这是使用的RuntimeExceptionMapper的一个示例：

@Provider
public class RuntimeExceptionMapperHandler implements ExceptionMapper<Exception>{

/** The invalid Data id. */
private String INTERNAL_SERVER_ERROR_ID = ""; // TODO which error Id

private String INTERNAL_SERVER_ERROR_MSG = ""; // TODO which error message
/** The invalid data or content  desc. */
private String INTERNAL_SERVER_ERROR_DESC = "An error has occurred during the processing of your request"; // TODO which error desc

/* (non-Javadoc)
 * @see javax.ws.rs.ext.ExceptionMapper#toResponse(java.lang.Throwable)
 */
@SuppressWarnings("unchecked")
@Override
public Response toResponse(Exception pEx) {
    return ErrorResponseBuilder.prepareInternalServerErrorRequestResponse(INTERNAL_SERVER_ERROR_ID, INTERNAL_SERVER_ERROR_DESC,INTERNAL_SERVER_ERROR_MSG).build();
}
}

但在这里，没有办法让车辆首先收到

请帮忙！

您可以创建一个简单的ContainerRequestFilter并包含在您的提供商中。在过滤方法中，您可以获得请求。

import javax.ws.rs.container.ContainerRequestContext;
import javax.ws.rs.container.ContainerRequestFilter;
import javax.ws.rs.ext.Provider;

@Provider
public class RequestInterceptor implements ContainerRequestFilter
{
    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException
    {       
        System.out.println("Filter executed.");
    }
}

如果REST WS中出现500 HTTP错误，则检索原始JSON请求
