我正在开始使用 Spring Boot。我正在做example Hello World application from the official getting started page 。当我得到我的 HelloController 的时候和我的Application我想用 ./gradlew build && java -jar build/libs/gs-spring-boot-0.1.0.jar 运行它，我得到了异常

我猜是because module java.annotation does not export javax.annotation.security to unnamed module @0x2f1f99d1 ，事实上，我试图在 Java 11 上运行它，这意味着应该采取一些措施让模块互相看到，但到底是什么？
设置sourceCompatibility和targetCompatibility至11 (与指南中的 1.8 相反)在 build.gradle 中没有帮助。将类路径设置为 "org.springframework.boot:spring-boot-gradle-plugin:2.1.0.RELEASE" 也没有.
我还缺少什么？
最佳答案
首先，您可以使用 VM arg
--add-exports java.annotation/javax.annotation.security=ALL-UNNAMED
但为了 future ，您实际上应该研究类 org.apache.catalina.startup.WebAnnotationSet 的实现至于为什么它要从java.annotation访问类模块javax.annotation.security.DeclareRoles .
在模块系统中，可以查看原因org.apache.catalina.startup.WebAnnotationSet正在解析到类路径中，因为如果它位于模块路径中，您就不会看到该错误。也许某些直接/传递引入它的依赖项没有放置在模块路径上。
关于java - 在 Java 11 上运行 Spring Boot "Hello World"？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53573297/
