xxl-job执行java任务报错： unable to find valid certification path to requested target

1、错误：xxl-job调用https接口显示证书验证失败

?

1 2	[错误信息：sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target] 2023-10-20 15:51:41 [com.xxl.job.core.thread.JobThread#run]-[164]-[Thread-4289]

2、问题是java的ssl证书不能自动引入。

3、处理：手动导入ca.pem证书到java

?

1 2 3 4 5 6 7 8 9 10

服务器上手动导入ca.pem find / -name cacerts keytool -import -alias clientkey -file ca.pem -keystore /java/jdk1.8.0_11/jre/lib/security/cacerts -trustcacerts 密码：changeit 输入：yes   --注释： 输入以下命令 keytool -import -aliias [证书名字] -keystore [cacerts路径] -file [证书地址] 即可。   keytool -import -alias clientkey -file C:\ssl\xxx.pem -keystore D:\jdks\1.8\jre\lib\security\cacerts -trustcacerts

4、重新启动java服务，再次执行任务成功
