带有jlink的SSLHandshakeException创建的运行时

Question

我有一个dropwizard应用程序，可以在标准JRE上正常运行。

我尝试使用jlink创建一个运行时，该运行时小得多：

/Library/Java/JavaVirtualMachines/jdk-11.jdk/Contents/Home/bin/jlink --no-header-files --no-man-pages --compress=2 --strip-debug --add-modules java.base,java.compiler,java.desktop,java.instrument,java.logging,java.management,java.naming,java.scripting,java.security.jgss,java.sql,java.xml,jdk.attach,jdk.jdi,jdk.management,jdk.unsupported --output jre

如果我使用创建的jlink运行时来运行它，则会引发连接到redis的错误（它的前面有通道）。

jlink是否遗漏了一些加密算法？

Answer 1

正如评论中提到的那样

嗯 如果我添加jdk.crypto.ec，则可以正常工作-为什么jdeps会遗漏一个，如果那个遗漏，还会有其他遗漏吗？

将jdk.crypto.ec添加到模块列表中可以解决此问题。

Answer 2

还可以将--bind-services（服务提供者模块中的链接及其依赖项）添加到 jlink 命令。但根据我的经验，这将使结果运行时间更大。但至少这是一个选项，可以快速找出观察到的问题是否是由于缺少 Service 实现造成的。

Answer 3

添加requires jdk.crypto.ec;到 module-info.java 中为我解决了这个问题。
