sun.security.validator.ValidatorException：PKIX路径构建失败：sun.security.provider.certpath.SunCertPathBuilderException：无法找到

Question

我真的很沮丧地解决了以下错误。我正在使用RestTemplate API运行junit测试用例，该API调用POST运行在8443

上的org.springframework.web.client.ResourceAccessException: I/O error on POST request for **"https://localhost:8443/google-rest/student?**":sun.security.validator.ValidatorException: PKIX path building

keytool -import -alias student_rsa -file D:\student_rsa.der -keystore

根据其他链接，我做了以下事项：

Illegal option:  Files\Java\jdk1.8.0_45\jre\lib\security\cacerts
keytool -importcert [OPTION]...

Imports a certificate or a certificate chain

Options:

 -noprompt                       do not prompt
 -trustcacerts                   trust certificates from cacerts

Use "keytool -help" for all available commands

我看到上面的命令执行出现以下错误： -

mv A/file B/

Answer 1

您需要在运行单元测试的JVM服务器上安装证书。为此，您需要先下载Web服务证书。

您可以从任何浏览器下载它（右键单击搜索栏中的证书图标，然后在详细信息选项卡中，单击复制到文件）

然后运行keytool命令（注意你需要添加包含下载的证书路径的-file参数）

keytool -import -alias student_rsa -keystore C:\Program Files\Java\jdk1.8.0_45\jre\lib\security\cacerts -file YourCertificate.cer

您还需要检查JUnit是否使用相同的jdk安装路径，因为它通常使用jre安装路径

This link帮助我解决了这个问题。

我希望这对你有用
