部署在Tomcat8上的Spring Boot MVC应用程序war文件因java.lang.TypeNotPresentException而失败

Question

我用Spring Boot编写了一个REST API,并将其打包为WAR文件.我将WAR复制到Tomcat 8的webapps文件夹并启动了tomcat服务.当服务器启动时,它会抛出一些由以下原因引起的异常:

java.lang.TypeNotPresentException:输入org.springframework.test.context.ContextConfiguration不存在

我解决了这个问题并发现如果我将webapp的lib和lib提供的文件夹上的JAR文件移动到Tomcat8/lib文件夹,则不会抛出任何异常并且API按预期工作.我不知道是什么导致了这个问题.我对他pom.xml的范围有一些依赖关系provided.也许他们给我带来了问题.

这是我的pom:

看看maven docs - 依赖机制

尝试删除提供的范围!它们将在您的战争中在WEB-INF/lib目录中提供.
