【问题标题】：Getting NoSuchMethodError while starting tomcat启动tomcat时出现NoSuchMethodError
【发布时间】：2020-02-10 21:49:37
【问题描述】：

我已经查看了建议在我的 pom.xml 中更新 Maven 依赖项并确保我的 lib 文件夹中没有任何旧版本的 spring-core 的所有其他答案，但我已经这样做了我仍然收到错误消息。我将在下面提供我的 pom.xml、web.xml 和 dispatcher-config.xml。

该项目编译得很好，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

对此的任何帮助表示赞赏。

【问题讨论】：

为什么要添加所有的 Spring Boot 依赖项？以及所有spring框架依赖项？您要么使用 spring boot 依赖项，它们将引入传递依赖项，要么只使用 spring 框架依赖项。

标签： spring maven

【解决方案1】：

根本原因：正如提到的异常，org.springframework.util.ReflectionUtils 中没有 accessConstructor()。这种方法自 Spring v5 以来就存在。查看 pom.xml，可能有些依赖使用的 Spring 版本小于 5

解决方案：要查找此类依赖项，您应该运行“mvn dependency:tree”命令并搜索与“org.springframework.util”相关的内容。 ..' => 很可能你会看到两个版本。然后你应该排除任何低于 v5 的 Spring 依赖项。
