现象

日志发生以下异常

- INTERNAL: Connection closed after GOAWAY. HTTP/2 error code: INTERNAL_ERROR, debug data: Stream 5 sent too many headers EOS: false
- INTERNAL: Invalid protobuf byte sequence
		While parsing a protocol message, the input ended unexpectedly in the middle of a field.  This could mean either that the input has been truncated or that an embedded message misreported its own length.
		iii. Protocol message contained an invalid tag (zero).

异常原因及解决方案:

原因

多线程同时向stream的observer句柄写数据，造成数据异常。

解决方案

observer加一个包装类，推送消息时使用包装类的推送方法，推送方法内加锁，使数据流能够顺序发送。类似于:

 public static class ObserverWrapper {
   
   
        @Getter
        private final String account;
        @Getter
        private final StreamObserver<Response> observer
