java.net.SocketException: Software caused connection abort: recv failed 異常分析

關鍵字: recv failed

java.net.SocketException: Software caused connection abort: recv failed

at java.net.SocketInputStream.read(SocketInputStream.java:182)

客戶機<－－>伺服器,之間是由一個socket 長串連來通訊，用戶端有一個接收線程在while(true){..}迴圈裡不停地從InputStream流中讀資料，客戶機每隔幾秒鐘發一次心跳包，如果連續未收到心跳包的次數已達到規定的次數，客戶機認為此鏈路異常，將socket關閉，那麼伺服器會拋出java.net.SocketException: Connection reset by peer異常，然後分配給此socket串連的線程退出，那麼用戶端在while(true){..}迴圈,讀取流時便會發java.net.SocketException:
Software caused connection abort: recv failed異常。
