按照最初的寫法，在登陸完畢后彈出聊天界面后會卡死，原因是當(dāng)時登陸界面和聊天界面都是使用的主線程，我的代碼沒有寫其他線程，無法多線程運行，因此在彈出聊天界面時線程不夠用了，就卡在了監(jiān)聽線程里，因為在監(jiān)聽線程中再有新的監(jiān)聽就會被卡住。后將啟動服務(wù)器和客戶端的部分改為線程，就解決了此問題。改善后的代碼簡練和清晰了很多，更方便大家參考，代碼如下：
登陸界面的實現(xiàn)
登陸界面主要使用了JFrame，以及相關(guān)的一些組件，并且在界面中加上監(jiān)聽

在登陸完畢后，需要跳轉(zhuǎn)到聊天界面，這里采用的方法是通過一個flag標(biāo)志來判斷是否登陸完畢，當(dāng)?shù)顷懲戤吅螅瑫?chuàng)建新的聊天界面，并且登陸頁面會被關(guān)閉
依然是雙端通信，假定一端為客戶端，一端為服務(wù)端，其實兩端都可為用戶。
聊天界面運行圖
先登陸Alice的賬號 密碼為123456
登陸成功后顯示ok，并等待連接
再登陸冷丁的賬號，密碼為123456
當(dāng)lding賬號登陸成功后完成連接，這時候會彈出兩個新的JFram窗口，為聊天見面
隨后可以發(fā)送消息，消息可以實時顯示時間，并顯示用戶名
一方發(fā)送的消息會在另一方的窗口上實時顯示出來
