我试图用
Java代码从安全(即SSL)网页上读取.
我正在尝试使用URLConnection(java.net)和Apache的HTTPClient.
在这两种情况下,当我发出请求时,我得到以下异常：
javax.net.ssl.SSLHandshakeException:

PKIX path validation failed:
java.security.cert.CertPathValidatorException:

请注意,我已经成功地建立了非ssl连接,但是不同的主机.
我也可以使用浏览器查看此页面 – 证书在那里正确验证.
我是否需要以某种方式更改证书的顺序,因为它们是从服务器检索的？
是否有一些我缺少的配置？
提前致谢,
利奥尔
我进一步挖掘,答案在于我需要将必要的证书导入JVM使用的密钥库来验证SSL.
密钥存储区是jre中用于运行程序的jre / lib / security文件夹下的“cacerts”文件.
我手动导出了网站的证书 – 所有这些证书.
然后我使用Sun提供的’keytool’实用程序将其导入我的默认密钥库.请注意,您必须以正确的顺序导入它们.
然后我把新的密钥库而不是JRE的密钥库 – 它起作用了.
我想将证书直接导入JRE的密钥库会更好,但该工具要求我输入一个我不知道的密码.
我相信还有一种方法可以更轻松地对此进行编程,但还没有找到它.我很乐意得到一些指针(JSSE中的TrustManager类？).
最后,一些功劳.这篇帖子：http://javaishdiscoveries.blogspot.com/2009/02/battle-with-cacerts-and-https.html帮我指出了正确的方向.
