您是否尝试调用closeConnection
或close
从属于容器或容器的 ThreadPool / Executor 的线程?
此外,一旦容器停止,所有会话也将停止。
变身@ClientEndpoint
close()
为...
public void close()
{
try
{
this.session.close();
}
catch (Exception e)
{
logger.trace("Exception occured while closing the connection",e);
}
}
并closeConnection()
简单地...
public closeConnection()
{
LifeCycle.stop(this.wc.getContainer());
System.exit(1);
}
可以在
https://github.com/joakime/javaxwebsocket-client-returncode找到一个工作示例
哪个有代码...
