我正在使用 RESTEASY 开发 Web 服务，以在遇到异常时设置响应状态代码。首先，我尝试了在本地运行良好的 resteasy 异常映射器。下面附上映射器代码。但是，当我将该 WS 上传到弹性 beantalk 时，总是返回 500（内部服务器错误）。
@Provider
public class LoadGridTileFailedExceptionMapper extends BaseExceptionMapper implements ExceptionMapper<LoadGridTileFailedException>
{
@Override
public Response toResponse(LoadGridTileFailedException e)
{
log(e.getMessage(), e);
return printMsg(e.getMessage(), DtmWebServiceReturnStatus.LOAD_GRID_TILE_FAILED_EXCEPTION_CODE);
}
}
然后我尝试抛出异常 WebApplicationException(ex, DtmWebServiceReturnStatus.LOAD_GRID_TILE_FAILED_EXCEPTION_CODE) 来绕过异常映射。结果是我得到了响应状态 498(LOAD_GRID_TILE_FAILED_EXCEPTION_CODE) 包裹在状态代码 500 中。
Apache Tomcat/7.0.27 - 错误报告
HTTP 状态 498 -

似乎弹性 beanstalk 包装了服务器端抛出的所有异常，状态码为 500？问题是如何绕过该功能并返回我设置的状态码作为响应？谢谢你。
更新
今天早上尝试更多请求，发现一些有趣的东西：
在弹性 beantalk 日志快照中获取正确的返回状态

但是在客户端，仍然有 500 :-(
printMsg 方法：
protected Response printMsg(String msg, int intStatus)
{
// Need this due to the Resteasy bug
ServiceDataCollector.processRequest(true);
ResponseBuilder builder = Response.status(intStatus);
builder.type("text/plain");
builder.entity("ERROR: " + msg);
Response rep = builder.build();
LOG.error(rep.getStatus() + ":" + rep.toString());
return rep;
