java - 使用 tools.jar 作为依赖项使用 java -jar 运行 spring boot

Question

我正在尝试运行一个需要 tools.jar 作为依赖项的 springboot 应用程序，我运行了“mvn package spring-boot:run”，一切正常，但是在用“mvn package spring-boot:repackage”打包之后，使用 java -jar 运行生成的 boot.jar 会抛出以下错误

java -jar "site-0.1.0-spring-boot.jar" 
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/tools/attach/AttachNotSupportedException

没有 mvn 我应该如何运行它？我做错了什么？

Answer 1

重新打包的 jar(例如“fat”jar)中未添加系统范围依赖项。这就是为什么您的应用程序在开发(使用“本地”类路径)时运行良好，而在作为单独的包启动时却运行不佳的原因。

upcoming Spring Boot 1.4.0.RC1 release will support this feature :您将能够在您的 Maven 插件配置中设置 includeSystemScope 并且将包含任何系统范围的依赖项。请注意，重新打包 tools.jar 可能是一种气味，请参阅 this question
