运行main方法时,我收到了ClassNotFoundException。 Spring依赖项是通过Maven添加的,这些依赖项在编译时解析。有很多类似的问题,但是当代码打包为jar并在eclipse之外执行时,每个人似乎都遇到了问题。当我在eclipse中运行它时,我实际上遇到了这个问题。
这是pom文件

栈跟踪
java.lang.NoClassDefFoundError: org / springframework / context / ApplicationContext引起: 抛出java.lang.ClassNotFoundException: org.springframework.context.ApplicationContext at java.net.URLClassLoader $ 1.run(URLClassLoader.java:200)at java.security.AccessController.doPrivileged(Native Method)at java.net.URLClassLoader.findClass(URLClassLoader.java:188)at java.lang.ClassLoader.loadClass(ClassLoader.java:307)at sun.misc.Launcher $ AppClassLoader.loadClass(Launcher.java:301)at at java.lang.ClassLoader.loadClass(ClassLoader.java:252)at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) 线程“main”中的异常
这是什么问题?谢谢!
答案 0 :(得分:1)
你需要spring-context依赖 快乐的编码
答案 1 :(得分:0)
如果没有堆栈跟踪,我们只能猜测,但是弹出给我的第一件事就是你将它用于springId的groupId:com.my.repo
。那应该是org.springframework
。
我不确定这是怎么编译的。
