java - 错误 : java. lang.NoSuchMethodError : org/springframework/asm/ClassVisitor. (I)V

Question

我的 POM 中有这两个依赖项，我认为这是造成此问题的原因，但我尝试了许多不同的方法和更新的版本，但没有任何效果。有人可以帮忙吗？POM.XML

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-aop</artifactId>
        <version>4.2.0.RELEASE</version>
    </dependency>

     <dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib</artifactId>
        <version>2.2</version>
    </dependency>      

Answer 1

问题的解决方案

1. 管理依赖项时似乎存在 JAR 冲突。
2. 在 Spring 4.2.0 中，ClassVisitor 类已包含在 Spring-core-4.2.0.RELEASE.jar 中，请参见下图。因此，不需要包含我在您的依赖项中找到的 spring-asm-3.1.3.RELEASE.jar 。
3. 始终建议使用 Bill of Materials当您使用Spring 3.2.X及以上版本时。
4. 请从依赖项中删除 CGLIB 代理，因为当您使用 Spring 3.2.X version 时不再需要它。以上。请参阅 spring-framework 文档。

5. 最后你的 POM 应该如下所示。谦虚地请求您忽略 hibernate 和 slf4j 依赖项。
