java JDK8>JDK10:PKIX路径生成失败：SunCertPathBuilderException:找不到请求目标的有效证书路径

Question

问题

• 我有一个SpringBoot应用程序，使用一个名为Launchdarkly的应用程序，它利用okhttp
• 我正在从JRE 8迁移到JRE 10，对其他资源的调用可以工作，但在使用okhttp进行的调用中失败

编辑：这可能发生在任何具有与我们的应用程序使用的证书链类似的证书链的应用程序上

javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

例外情况

错误发生在该线程中

设置

• 使用jlink并选择模块来构建小型JRE
  • 使用Docker安装在https://dev.to/gimlet2/dockerizing-java-10-spring-boot-app-3b4c
  • 当前应用程序在Docker中的JRE8上运行（相同的基本图像）
• 我只有JAVA_HOME集。。。不确定我们还需要什么

Java 10版本详细信息

使用上述方法安装

root@e0776fd790e7:/runtime# ls -la /etc/ssl/certs/java/cacerts
-rw-r--r-- 1 root root 177280 Oct 29 16:29 /etc/ssl/certs/java/cacerts
root@e0776fd790e7:/runtime# java -version
openjdk version "10" 2018-03-20
OpenJDK Runtime Environment 18.3 (build 10+46)
OpenJDK 64-Bit Server VM 18.3 (build 10+46, mixed mode)

密钥库已设置

Java10密钥库可以看到它

root@17000659d1ec:/runtime# keytool -cacerts -list
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 80 entries

如https://dzone.com/articles/openjdk-10-now-includes-root-ca-certificates所述

尝试

• 我想知道你能帮上什么忙
  • 来自Unable to find valid certification path to requested target - error even after cert imported
• 试图从java 8调用cacerts到java 10

• Tried to symlink or copy cacerts from JRE dir to /etc/ssl/certs/java/cacerts WORKS! ALONG WITH COPYING FROM JDK 8

• 已尝试设置-Djavax.net.ssl.trustStore=/opt/jdk-minimal/jre/lib/security/cacerts

编辑：查看我的答案

Answer 1

从JDK 8迁移到JDK 10时的解决方案

• 证书真的不一样
  • JDK 10有80个，而JDK 8有151个
• JDK 10最近被添加到certs
  • https://dzone.com/articles/openjdk-10-now-includes-root-ca-certificates
  • http://openjdk.java.net/jeps/319

JDK 10

root@c339504909345:/opt/jdk-minimal/jre/lib/security #  keytool -cacerts -list
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 80 entries

JDK 8

root@c39596768075:/usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts #  keytool -cacerts -list
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 151 entries

修复的步骤

我还没有检查哪个证书链不受信任，但服务器的URL证书是有效的。。。JDK 10中的cacerts有一条链从今天起就断了。我可以断言，因为从https://download.java.net/java/GA/jdk10/10/binaries/openjdk-10_linux-x64_bin.tar.gz下载的内容被安装在一个全新的Docker映像中

• 我删除了JDK 10证书，并将其替换为JDK 8
• 因为我正在构建Docker图像，所以我可以使用多阶段构建快速实现这一点
  • 我正在使用jlink作为/opt/jdk/bin/jlink \ module-path /opt/jdk/jmods...构建一个最小的JRE

下面是不同的路径和命令序列

# Java 8
COPY  from=marcellodesales-springboot-builder-jdk8 /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts /etc/ssl/certs/java/cacerts

# Java 10
RUN rm -f /opt/jdk-minimal/jre/lib/security/cacerts
RUN ln -s /etc/ssl/certs/java/cacerts /opt/jdk-minimal/jre/lib/security/cacerts
