一、问题现象
之前一个项目使用Java请求客户提供的接口时，返回报错如下：

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: timestamp check failed

二、原因

java.security.cert.CertPathValidatorException: timestamp check failed 异常表明在验证证书链的过程中，时间戳检查未能通过。这通常与证书的有效期、系统时间或时间戳服务器的时间不一致有关。

‌系统时间不正确‌：如果系统时间与当前时间存在显著差异，那么证书的时间戳验证可能会失败，因为证书可能被视为已过期或尚未生效。

证书已过期‌：证书本身可能已经超过了其有效期。

时间戳服务器问题‌：如果证书包含时间戳，并且该时间戳是通过时间戳服务器生成的，那么时间戳服务器的时间错误或证书链中涉及的时间戳服务器不可信也可能导致此异常。

三、证书解决方法

把上面这段代码copy出来，什么都不要改（包括package名）；再在本地新建一个跟此类名相同的.java文件，将内容粘贴进去；然后进入命令行

1、编译：

javac InstallCert.java
2、运行

java InstallCert URL域名
（说明：java InstallCert 后面需要替换为自己对应Java请求出错的站点URL，不需要输入 https:// 信息，有的需要加上端口号）

在运行过程中，会看到以下信息：

at java.security.cert.CertPathBuilder.build(CertPathBuilder.java:194)
at sun.security.validator.PKIXValidator.doBuild(PKIXValidator.java:216)
... 13 more
Server sent 2 certificate(s):
1 Subject CN=ecc.fedora.redhat.com, O=example.com, C=US

md5 dd d1 a8 03 d7 6c 4b 11 a7 3d 74 28 89 d0 67 54

Enter certificate to add to trusted keystore or 'q' to quit: [1]
这个时候输入1，直接回车即可；然后会在相应的目录下生成一个名为 jssecacerts 的证书

将此证书复制到 $JAVA_HOME/jre/lib/security 目录下，liunx系统也可以
