无法自省类 org.springframework.boot.web.servlet.support.SpringBootServletInitializer 上的注释方法

Question

我有一个问题。当我尝试调试我的 springboot 应用程序时出现此错误，但出现以下错误

org.springframework.beans.factory.BeanDefinitionStoreException: Failed to parse configuration class [com.app.myapp.MyappApplication]; nested exception is java.lang.IllegalStateException:Failed to introspect annotated methods on class org.springframework.boot.web.servlet.support.SpringBootServletInitializer

我的

可能是什么问题？

Answer 1

只有无效缓存对我没有帮助。请在 pom.xml 中检查您的 tomcat 的范围。有时范围是“提供”的，这就是它不编译类并抛出此错误的原因：

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-tomcat</artifactId>
        <!--<scope>provided</scope>-->
    </dependency>

如果您在这里评论任何范围，请确保您重新启动系统，如果需要，也使索引缓存无效。这对我有用。

Answer 2

我的问题是通过使缓存无效并重新启动我的 IDE 来解决的

谢谢

Answer 3

我尝试了这篇文章中提供的两种解决方案：使缓存无效并删除了依赖范围。

在我删除范围（“提供”）后它对我有用。

请不要忘记在删除范围后重新加载 Maven 项目。
