異常查錯java.net.SocketException: Connection reset

　　用httpclient訪問后台接口報錯java.net.SocketException: Software caused connection abort: recv failed，百度了一圈都說是由於服務器端關閉了連接，說是因為長連接的問題，於是我就把httpclient的請求設置為短連接

HttpPost httpPost=new HttpPost(url);
        httpPost.setProtocolVersion(HttpVersion.HTTP_1_0);
        httpPost.addHeader(HTTP.CONN_DIRECTIVE, HTTP.CONN_CLOSE);

但是問題還是存在java.net.SocketException: Connection reset，后來想着是服務器端關閉了連接才想到代碼里用了多線程，公用的代碼沒有做同步，於是把httpclient公用方法加synchronized關鍵字，問題解決
