更新:奇怪的是,只有当我使用Gradle构建jar时才会抛出此错误。 Maven生成的jar运行正常!所以我现在正在探索我的gradle构建脚本/ spring boot配置是否以及如何失败。
我有一个弹簧启动应用程序抛出以下错误

答案 0 :(得分:6)
我们(Spring Boot团队)曾几次见过这种问题。不幸的是,JVM的诊断程序非常糟糕。它试图告诉你的是它遇到了一个带有Class []属性的注释,它引用了一个不在类路径上的类。如果它告诉你缺少的课程是什么,那将是非常有帮助的。
我尝试使用上面的代码重新创建您的失败,但无法这样做。当您使用Maven时,请尝试查看unzip -l
的输出与Maven和Gradle构建的jar对比,看看您是否可以发现Gradle案例中缺少的内容。
答案 1 :(得分:0)
在sun.reflect.annotation.TypeNotPresentExceptionProxy.TypeNotPresentExceptionProxy(String,Throwable)中添加一个断点。 这将为您提供缺少的课程。
