我正在构建springboot应用程序，但在启动应用程序时，它抛出了以下异常。我正在通过ServletContextInitializer bean配置ServletContext。任何帮助或输入将不胜感激。

我正在创建ServletContextInitializer bean，并在onStartup方法中创建AnnotationConfigWebApplicationContext。
因此，我错过了为这个WebApplicationContext设置ServletContext，这给我造成了巨大的破坏。
所以最后为这个AnnotationConfigWebApplicationContext对象设置setServletContext（servletContext），我就解决了我的问题。

在我的案例中，错误是由Intellij Idea中Gradle项目中的冗余
/out和/build文件夹引起的。IntelliJ Idea提供了两种构建和运行Gradle项目的方法。通过IntelliJ内部编译和运行-或者通过将构建和执行委托给Gradle。
它们中的每一个都为编译的类创建自己的输出文件夹。
IntelliJ -
/outGradle -/build当您切换构建运行的方式（从Gradle到IntelliJ，反之亦然）时，另一个的输出文件夹仍然存在-导致类路径上存在重复的类。
不幸的是，这两个文件夹都在IntelliJ的类路径上：sample folder structure in IntelliJ
对我来说，运行Gradle
clean或删除所有/out文件夹就可以了。下面是一个Gradle任务，用于删除整个项目树中的
/out文件夹（如果是多项目）：
