各位好，我想請教一個java 1.6 vs 1.8的問題我目前有一支程式要跟主機用SSL溝通，丟一些資料底下是我連線，收送的部分我在jre1.6環境下跑不用disconnect，只要socket建通，直接write and read 不管送收幾次都可以但是只要環境切到1.8下,第一次執行收送是成功的，但只要在馬上執行一次同樣動作主機那邊似乎就收到他們解碼不出來的東西，所以沒有回應我我client就會timeout 我疑惑的是 "socket建立起來，第一次收送，成功正常，但socket沒有斷，只是再第二次送資料，結果就是主機收到解不出來的東西" 不知道有沒有人可以給我一點方向去查問題呢感謝回答 //connect public boolean connect() { logger.info("Start"); TrustManager[] trustManager = null; SSLContext context = null; try { trustManager = new TrustManager [] { (TrustManager) new MyX509TrustManager(CAFilePath,clentCertPath) }; context = SSLContext.getInstance("SSL"); context.init(null, trustManager, null); SocketFactory sf = context.getSocketFactory(); sslSocket = (SSLSocket) sf.createSocket(mUrl, mPort); sslSocket.setSoTimeout(10*1000);//timeout 10 sec } catch (NoSuchAlgorithmException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (KeyManagementException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e1) { // TODO Auto-generated catch block e1.printStackTrace(); logger.error(e1.getMessage()); } if(sslSocket==null) return false; logger.info("sslSocket OK"); logger.info("end"); return true; } //收送 public String sendRequest(String req){ try { if (sslSocket == null) { //throw new IOException(ICMASResponse.scErr_NoConnection); logger.error("SSL Socket NoConnection"); return null; //throw new IOException("SSL Socket NoConnection"); } OutputStream out= sslSocket.getOutputStream(); InputStream in = sslSocket.getInputStream(); out.write(req.getBytes("UTF-8")); out.flush(); String resp = null; int len = in.read(mBuffer); if (len > 0) { resp = new String(Arrays.copyOf(mBuffer, len), "UTF-8"); } logger.info("resp:"+resp); //out.close(); //!!Note: close() means closeSocket //in.close(); //!!Note: close() means closeSocket return resp; } catch(IOException e) { logger.error(e.getMessage()); e.printStackTrace(); return null; } } // main public static void main(String args[]) { logger.info("AP Start"); SSL ssl = null; Properties logp = new Properties(); try { logp.load(SSL_Test.class.getClassLoader(). getResourceAsStream("log4j.properties")); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } try { String req = "<1100>000</1100><1200>999</1200>"; String resp = null; ssl = new SSL("192.168.1.23", 7000, null, null); if(!ssl.connect()) { logger.info("connect fail"); return; } //no.1 resp = ssl.sendRequest(req); logger.info("1st resp:"+resp); //no.2 resp = ssl.sendRequest(req); logger.info("2nd resp:"+resp); //no.3 resp = ssl.sendRequest(req); logger.info("3th resp:"+resp); } catch (Exception e) { logger.error(e.getMessage()); e.printStackTrace(); } finally{ ssl.disconnect(); } } -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 223.143.163.206 ※ 文章網址: https://www.ptt.cc/bbs/java/M.1427340868.A.403.html
