我们有一个带有spring web应用程序的tomcat。 我们有很多junit测试。
当我们将记录器值设置为“DEBUG”时，我们会遇到大量以下错误：

任何想法为什么？
答案 0 :(得分：2)
它刚好发生在我身上。
在我的情况下，我从TestNG到JUnit（唉）所有的项目测试类开始
我在迁移它们时保留了一些java testNG文件，在JUnit下逐个编译，但它们不再编译（我已经删除了maven依赖项）。
(AnnotationAttributesReadingVisitor.java:184).visitEnd() - Failed to class-load type while reading annotation metadata. etc
java.lang.ClassNotFoundException: BeforeClass
删除最后一个testNG文件后 还有一个清洁的日食“MAVEN” - ＆gt; “更新项目......它消失了。
虽然它没有解释你的情况，但这个场景可以为你带来光明！
你有使用Junit的旧版测试类缺少正确的Junit jar来编译......

堆栈跟踪说明了一切：
java.lang.ClassNotFoundException: org.junit.After
jUnit或jUnit的正确版本不在类路径上。
