Question

我正在使用IntelliJ中的spring初始化程序插件创建一个简单的项目我得到以下异常

Exception in thread "main" java.lang.NoClassDefFoundError: org/springframework/context/ApplicationEvent

at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
... 6 more

Process finished with exit code 1

版本有问题还是我错过了什么？我使用的是jdk1.8.0_121，spring 4.3.7-RELEASE和spring-boot 1.5.2 IntelliJ 2017.1所有64位

请注意，intelliJ Spring会自动生成pom.xml文件，所以我不认为依赖项存在问题。但无论如何这里是我的pom.xml文件。
