我正在尝试使用 Java 11 中的 jlink 为 Spring Boot 应用程序创建最小化的 jre。我已经能够让它与完整的 Java 11 jre 一起运行，但是我得到了一个我很难破译的堆栈跟踪。我假设根本原因是某种依赖性冲突，因为它适用于完整的 jre 而不是子集。
我使用的是 spring-boot 1.5.19，目前包含的模块有:java.base、java.logging、java.instrument、java.sql、java.naming 和 java.desktop。
请告诉我我还可以提供哪些其他信息。谢谢!

最佳答案
本例中的简短答案是将“jdk.unsupported”模块添加到 Jlink 模块的参数列表中。
我基于这样的事实:我在尝试使用 JDK17 和 SpringBoot 项目构建自定义 JRE 时遇到了类似的问题(具有类似的 stackstrace)。这是堆栈溢出帖子帮助我解决了这个问题: NoSuchMethodException: springframework.boot.autoconfigure.http.HttpMessageConverters
关于java - 使用 JLink JRE 进行 Spring Boot，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55795538/
