我正在编写代码以使用Java HttpsURLConnection连接到http服务器。服务器位于代理服务器后面。请在下面找到我使用的代码：
private void setSSLProperties() {
if (isSSLRequired()) {
if (true) {
System.out.println(this.getArgument("KEY_STORE", true));
System.out.println(this.getArgument("KEY_PASS", true));
System.out.println(this.getTrustStoreType());
}
System.setProperty("https.protocols", "TLSv1");
System.setProperty("javax.net.debug", "all");
System.setProperty("javax.net.ssl.trustStore",
this.getArgument("KEY_STORE", true));
System.setProperty("javax.net.ssl.trustStorePassword",
this.getArgument("KEY_PASS", true));
System.setProperty("javax.net.ssl.trustStoreType",
this.getTrustStoreType());
HttpsURLConnection.setFollowRedirects(true);
}
}
private void setProxyProperties() {
if (this.isProxyRequired()) {
if (this.isSSLRequired()) {
System.setProperty("https.proxyHost", this.getProxyHost());
System.setProperty("https.proxyPort", this.getProxyPort() + "");
} else {
System.setProperty("http.proxyHost", this.getProxyHost());
System.setProperty("http.proxyPort", this.getProxyPort() + "");
}
}
}
private URLConnection getConnection(Document inputDocument)
throws IOException {
URLConnection conn = null;
String urlstring = this.getUrl(inputDocument);
if (true) {
System.out.println("URL: " + urlstring);
}
URL url = new URL(urlstring);
this.setProxyProperties();
if (this.isSSLRequired()) {
this.setSSLProperties();
conn = (HttpsURLConnection) url.openConnection();
((HttpsURLConnection) conn).setRequestMethod("GET");
conn.setRequestProperty("User-Agent", "Mozilla/5.0");
} else {
conn = (HttpURLConnection) url.openConnection();
((HttpURLConnection) conn).setRequestMethod("GET");
conn.setRequestProperty("User-Agent", "Mozilla/5.0");
}
conn.setDoOutput(false);
conn.setDoInput(true);
conn.setUseCaches(false);
return conn;
}
private String getContent(URLConnection conn) throws IOException {
if (this.isSSLRequired()) {
System.out.println("Response Code: " + ((HttpsURLConnection)conn).getResponseCode());
} else {
System.out.println("Response Code: " + ((HttpURLConnection)conn).getResponseCode());
}
InputStreamReader isr = new InputStreamReader(conn.getInputStream());
BufferedReader br = new BufferedReader(isr);
String responseString = "";
String responseLine = null;
while ((responseLine = br.readLine()) != null) {
responseString = responseString + responseLine;
}
return responseString;
}
我在行
中收到以下错误InputStreamReader isr = new InputStreamReader(conn.getInputStream());
at conn.getInputStream（）;
请在下面找到错误和SSL日志：

我真的很感激如果有人可以建议我为什么会发生这种错误。由于我没有从客户端关闭连接，为什么连接被终止。
JDK版本：1.6
答案 0 :(得分：1)
我能够通过将Java升级到Java SE 8来解决这个问题。问题的原因是服务器期望SSL协议，如果TLSv1.1在Java 1.6中不可用，客户端正在使用它。更新到Java 8并使用https.protocol系统变量指定协议后，错误得到解决。
