我正在尝试使用jdk版本1.6.0_29编写Java https客户端（使用HttpsURLConnection）。
然后，我将证书/wlserver_10.3/server/lib/CertGenCA.der导入到客户端的密钥库中。通过以下命令：
keytool-导入-alias测试-keystore“ D：\ Program Files \ Java \ jdk1.6.0_29 \ jre \ lib \ security \ cacerts”-文件CertGenCA.der
问题是我不断收到“线程“ main”中的异常” javax.net.ssl.SSLHandshakeException：握手期间远程主机关闭连接” SSL调试输出如下：

不确定如何解释所有这些信息
我的代码是从Eclipse和URL（JAX-WS）运行的，它位于LAB和solaris框中
我的测试客户端代码如下：
URL wsdlLocation = new URL("https://server.lab.ciso.com:8833/Impl/Service?wsdl");
System.setProperty("weblogic.security.SSL.ignoreHostnameVerification", "true");
System.setProperty("javax.net.ssl.trustStore", "D:\\Program Files\\Java\\jdk1.6.0_29\\jre\\lib\\security\\cacerts");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
System.setProperty("https.protocols", "SSLv3");
SSLSocketFactory sslsocketfactory = (SSLSocketFactory) SSLSocketFactory.getDefault();
HttpsURLConnection conn = null;
try {
conn = (HttpsURLConnection) wsdlLocation.openConnection();
conn.setSSLSocketFactory(sslsocketfactory);
conn.setDoOutput(true);
conn.setUseCaches(false);
conn.setRequestMethod("GET");
conn.setRequestProperty("Content-Type","application/Json");
conn.setDoInput(true);
conn.connect();
BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line;
while ( ((line = br.readLine()) != null)) {
if((line.indexOf("wsp:PolicyReference") == -1))
sb.append(line+"\n");
}
br.close();
System.out.println("Random code::"+sb.toString());
} finally {
if (conn != null) {
conn.disconnect();
}
}
最佳答案
首先，修改JDK安装的cacerts信任库是非常不好的做法，因为您会因为漏洞而使用当前每周大约发布一次的JDK更新来放松修改。
如果要使用修改后的Java信任库，请将其复制到项目中，然后从那里进行修改/使用。
您的代码的主要问题（我认为是）是使用以下调用将协议限制为SSLv3。
SSL3非常老，在某些情况下不安全，因此您应该使用TLS v1.0或更高版本。如果服务器限制为TLS（此处似乎是这种情况），则连接将失败。
因此，将System.setProperty("https.protocols", "SSLv3");更改为"SSLv3"或"TLSv1"（"TLSv1.1"仅受Java 7支持AFAIR）。
