Question

我已经查看了所有其他答案，这些建议建议更新pom.xml中的Maven依赖项，并确保lib文件夹中没有任何旧版本的spring-core，但是我已经做到了而且仍然出现错误。我将在下面提供我的pom.xml，web.xml和dispatcher-config.xml。

项目编译正常，但是当我尝试在本地Tomcat服务器上运行它时，这是我得到的错误：

严重：ServletContainerInitializer处理期间出错

由以下原因引起：java.lang.NoSuchMethodError：org.springframework.util.ReflectionUtils.accessibleConstructor（Ljava / lang / Class; [Ljava / lang / Class;）Ljava / lang / reflect / Constructor;

在org.springframework.web.SpringServletContainerInitializer.onStartup（SpringServletContainerInitializer.java:155） ...另外8个

对此有任何帮助。

Answer 1

根本原因：作为例外，在org.springframework.util.ReflectionUtils中没有accessibleConstructor（）。从Spring v5开始就有这种方法。查看pom.xml，也许某些依赖项使用的Spring版本小于5

解决方案：要查找此类依赖项，应运行“ mvn依赖关系：树”命令，并搜索与“ org.springframework.util”相关的内容。 .. '=>很可能会看到两个版本。然后，您应该排除所有小于v5的Spring依赖项。
