Question

我需要关闭连接，但我得到了这个

.mdf

这是我的套接字代码：

2016-10-28 10:46:07.624:WARN:oeji.nio:handle failed
java.lang.NullPointerException: ssl == null

我无法理解该错误的原因是什么以及如何解决？我查看了jetty docs并在这里查看了一些帖子，但没有发现任何关于该特定错误的信息

Answer 1

您必须停止WebSocketClient。

试试这个：

public void stop(){
 try {
     webSocketClient.stop();
 } catch (Throwable t) {
     t.printStackTrace();//this not called
 }
}

或

public void stop(){
 try {
     webSocketClient.stop();
     connection.close();
 } catch (Throwable t) {
     t.printStackTrace();//this not called
 }
}
