provider throw的所有异常在consumer端都会被包装为RpcException。
怎么能在consumer端重放provider发生的异常呢
这里是UnaryClientStream$UnaryClientTransportObserver#getThrowable
```
private Throwable getThrowable(Metadata metadata) {
if (null == metadata) {
return null;
}
// second get status detail
if
(!metadata.contains(TripleHeaderEnum.STATUS_DETAIL_KEY.getHeader())) {
return null;
}
final CharSequence raw =
metadata.get(TripleHeaderEnum.STATUS_DETAIL_KEY.getHeader());
byte[] statusDetailBin = TripleUtil.decodeASCIIByte(raw);
ClassLoader tccl =
Thread.currentThread().getContextClassLoader();
try {
final Status statusDetail =
TripleUtil.unpack(statusDetailBin, Status.class);
List<Any> detailList = statusDetail.getDetailsList();
Map<Class<?>, Object> classObjectMap =
TripleUtil.tranFromStatusDetails(detailList);
// get common exception from DebugInfo
DebugInfo debugInfo = (DebugInfo)
classObjectMap.get(DebugInfo.class);
if (debugInfo == null) {
return new RpcException(statusDetail.getCode(),
statusDetail.getMessage());
}
String msg =
ExceptionUtils.getStackFrameString(debugInfo.getStackEntriesList());
return new RpcException(statusDetail.getCode(), msg);
} finally {
ClassLoadUtil.switchContextLoader(tccl);
}
}
```
consumer处理异常时都会被包装为RpcException
