我使用Grizzly Web套接字实现通过我的Java应用程序连接到Web套接字服务器。
@OnError
public void error(Session session, Throwable t) {
Log4Me.getLogger().debug("WebSocket Error {} on session {} ", session, t);
Log4Me.getLogger().error("Error on session {}, Exception:{}", session.getId(), t.getMessage());
}
@OnClose
public void closedConnection(Session session, CloseReason reason) {
Log4Me.getLogger().info("Session closed. session: {}, Reason {}", session, reason);
}
@OnMessage
public void onMessage(Session session, ByteBuffer message) {
}
@OnOpen
public void onOpen(Session session) {
}
大部分时间它按预期工作，但有时onError回调被解析。当我在删除@OnError注释后运行应用程序时，我得到一个异常：

它似乎试图调用我的类的方法但它失败了..但我不知道为什么它没有错误的情况...
有什么想法吗？
