Error: java.lang.NoSuchMethodError: org/springframework/asm/ClassVisitor.<init>(I)V
我的 POM 中有这两个依赖项，我认为这是造成这个问题的原因，但我尝试了许多不同的方法和更新版本，但对我没有任何作用。有人可以帮忙吗？

问题的解决方案
- 管理您的依赖项时似乎存在 JAR 冲突。
- 在Spring 4.2.0中，ClassVisitor class已经包含在Spring-core-4.2.0.RELEASE.jar中，请看下图。因此，无需包含我在您的依赖项中找到的 spring-asm-3.1.3.RELEASE.jar 。
- 在使用Spring3.2.X及以上版本时，始终建议使用Bill of Materials。
- 请从依赖项中删除 CGLIB 代理，因为当您使用 Spring 3.2.X version 及更高版本时不再需要它。请参考 spring-framework 文档。
最后你的POM应该像下面这样。谦虚地请求您忽略 hibernate 和 slf4j 依赖项。
