Hi，
You can you @Context, example:
@Provider
public class ExceptionMapperSupport implements ExceptionMapper {
private static final Logger LOGGER = Logger
.getLogger(ExceptionMapperSupport.class);
private static final String CONTEXT_ATTRIBUTE = WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE;
@Context
private HttpServletRequest request;
@Context
private ServletContext servletContext;
/**
* 异常处理
*
* @param exception
* @return 异常处理后的Response对象
*/
public Response toResponse(Exception exception) {
String message = "Internal Server Error";
Status statusCode = Status.INTERNAL_SERVER_ERROR;
WebApplicationContext context = (WebApplicationContext) servletContext
.getAttribute(CONTEXT_ATTRIBUTE);
if (exception instanceof BaseException) {
BaseException baseException = (BaseException) exception;
String code = baseException.getCode();
Object[] args = baseException.getValues();
message = context.getMessage(code, args, exception.getMessage(),
request.getLocale());
} else if (exception instanceof NotFoundException) {
message = "Request Not Found";
statusCode = Status.NOT_FOUND;
} else if (exception instanceof WebApplicationException) {
//WebApplicationException类异常直接由对应的异常定义返回的消息
LOGGER.error(message, exception);
WebApplicationException webAppException = (WebApplicationException) exception;
return webAppException.getResponse();
} else {
message = context.getMessage(exception.getMessage(), null, message,
request.getLocale());
}
LOGGER.error(message, exception);
return Response.ok(message, MediaType.TEXT_PLAIN).status(statusCode)
.build();
}
}

Subject: [Jersey] ExceptionMapper and the request
Hi!
Is there anyway in an ExceptionMapper to get the original request? I was thinking that for an Accepts header of application/json I would return a JSON response but for an Accepts of text/html I would redirect to our main page. Any other way I might accomplish that?
Cheers,
Craig
