Question

我在客户端使用smack api建立与openfire的连接。能够生成成功的连接并且可以聊天。但是在聊了一段时间之后我得到了以下异常。

通过对相关帖子的几个答案，但在我的方案中没有找到此异常的实际原因。我使用以下代码与openfire建立连接：

try { XMPPTCPConnectionConfiguration config = XMPPTCPConnectionConfiguration.builder()
                    .setUsernameAndPassword(userName+Constants.openFireIP, password)
                    .setServiceName("182.**.***.**")
                    .setHost("182.**.***.**")
                    .setPort(5222)
                    .setResource("/Smack")
                    .build();
            connecton = new XMPPTCPConnection(config);
            System.out.println("connecton ######## "+connecton);
            makeConnectionAvailable();
        }
        catch(Exception e){
            System.out.println("Exception "+e.getMessage());
            e.printStackTrace();
        } 


public void makeConnectionAvailable(){
    try{
        if(!connecton.isConnected()){
            connecton.connect();
            connecton.login();
            connecton.addConnectionListener(connectionListener);
        }else if(!connecton.isAuthenticated()){
            connecton.login();
        }
}

catch (Exception e){
        e.printStackTrace();
    }

}

由于此连接已终止并丢失传入的聊天消息，直到我再次建立连接。如果有人解决这类问题，请告诉我。

AbstractXMPPConnection：连接因错误而关闭：java.net.SocketException：recvfrom failed：ECONNRESET（由对等方重置连接）
