<p>在tomcat中出現這個錯誤是因爲客戶端在發送請求後，還沒等服務器響應就斷開了鏈接，有多是由於網絡緣由，忽然網斷了，可是若是錯誤頻繁出現的話，可能就是服務端的問題了。</p>web
<p>tomcat中配置了一個鏈接超時時間connectionTimeout，若是在這個時間以後客戶端還未獲得服務器端的響應的話，就會主動斷開鏈接，這樣就會出現上述異常了，tomcat中默認的鏈接超時時間是20秒，咱們通常最好設置爲60秒，從而避免後臺程序處理時間長致使鏈接斷開。</p>apache
<p><strong>設置方法</strong> <br> 進入tomcat中conf目錄，打開server.xml文件，找到配置端口的地方</p>json
