Jersey:如何注册一个省略了一些子类的 ExceptionMapper？

Question

我如何注册一个包罗万象的 ExceptionMapper<Exception>确实如此 不是 拦截 WebApplicationException哪个 Jersey 提供特殊处理？

更新 :我提交了此功能请求:http://java.net/jira/browse/JERSEY-1607

Answer 1

我最终注册了一个 ExceptionMapper:

import com.google.inject.Singleton;
import com.sun.jersey.api.container.MappableContainerException;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;

/**

 */
@Provider
@Singleton
public class RuntimeExceptionMapper implements ExceptionMapper<RuntimeException>
{
    @Override
    public Response toResponse(RuntimeException e)
    {
        if (e instanceof WebApplicationException)
        {
            // WORKAROUND: Attempt to mirror Jersey's built-in behavior.
            // @see http://java.net/jira/browse/JERSEY-1607
            WebApplicationException webApplicationException = (WebApplicationException) e;
            return webApplicationException.getResponse();
        }
        // Jetty generates a log entry whenever an exception is thrown. If we don't register an
        // ExceptionMapper, Jersey will log the exception a second time.
        throw new MappableContainerException(e);
    }
}
