为HTTPSURLConnection设置TLS协议

我需要对使用TLS协议连接的F5机器起作用 . 为此，我构建了一个使用HTTPsURLConnection对象的类 .

m_httpsConnection = (HttpsURLConnection) m_url.openConnection();

然后，我下载了F5证书文件，使用JDK keytool创建密钥库，并使用它来尝试设置连接以使用TLS协议：

InputStream in = new FileInputStream(new File("c:/temp/F5keystore"));
        KeyStore ks = KeyStore.getInstance(KeyStore.getDefaultType());
        ks.load(in, "changeit".toCharArray());
        in.close();

        TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
        tmf.init(ks);
        X509TrustManager defaultTrustManager = (X509TrustManager)tmf.getTrustManagers()[0];
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, new TrustManager[] {defaultTrustManager}, null);
        SSLSocketFactory sslSocketFactory = context.getSocketFactory();

        ((HttpsURLConnection) m_httpsConnection).setSSLSocketFactory(sslSocketFactory);

（我饶了你们的捕获......）

代码似乎正在迅速传递，但当我这样做时：

OutputStream os = m_httpsConnection.getOutputStream();

我明白了......

“javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException： unable to find valid certification path to requested target ”

现在，我在c：\ temp下有文件F5keystore文件，那为什么不找到它呢？

这真的是将TLS设置为连接的正确方法吗？现在我在打开连接后这样做，虽然我可能认为它应该在连接打开之前 . 但是，连接仍然是空的...
