解决 Protobuf 生成代码中 MissingOverride 错误

Yes, the error message is suggesting that you add the ' @Override' annotation to the 'getUserNameBytes' method in the 'SysFlightTicketOrBuilder' interface. The correct code should be:

@Override
public com.google.protobuf.ByteString getUserNameBytes();

Adding the ' @Override' annotation indicates that the method is intended to override a method from a superclass or interface.
