java - "unable to find valid certification path to requested target"，但是浏览器说没问题

Question

我正在开发一个 Java 应用程序，它连接到 https://ut.eurodw.eu/ 上公开的 SOAP 服务。 (欧洲数据仓库的测试环境)。我正在使用我的开发机器，最近使用 Windows 8.1 重新格式化。今天，我尝试从我的程序中通过 SOAP 向他们发送创建请求并收到此错误:

点击我上面的链接可以看到，这不是自签名证书，而是由 GoDaddy 公共(public) CA 发布，我的 Firefox 浏览器可以识别。我的 Java 版本是 1.7.0_60-b19。修改代码以允许不安全的 SSL 连接将是一个坏主意。

我想确保 eurodw 的证书在信任库中。我该如何检查？以及如何导入新证书？

PS 我目前无法在部署最终应用程序的服务器上进行测试:我只能使用我自己的 Tomcat 安装。

Answer 1

可以在以下 keystore 中找到不同的证书:

%JAVA_HOME%/jre/lib/security/cacerts

如果您想列出受信任的证书:

keytool -list -keystore %JAVA_HOME%/jre/lib/security/cacerts

密码是可选的。

如果要添加条目:

首先，导出要导入的证书，假设它是 c:\cert.crt。最好的方法是使用firefox，右键点击URL中的锁图，点击几下，就有了导出功能。

然后输入:

keytool -import -alias my-cert -file c:\cert.crt -keystore %JAVA_HOME%/jre/lib/security/cacerts

默认密码为:changeit

别名是用户定义的标签，明智地选择它，记住如果有一天你需要它，它是什么。

有了这一切，您应该能够信任证书并让一切恢复正常。
