启动雄猫时获取 NoSuchMethodError

Question

我已经查看了所有其他建议更新我的pom中的Maven依赖项的答案.xml并确保我的lib文件夹中没有任何旧版本的spring-core，但是我已经这样做了，但我仍然收到错误。我将在下面提供我的pom.xml，web.xml和调度程序配置.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：

任何帮助，不胜感激。

Answer 1

根本原因：如异常所述，org.springframework.util.ReflectionUtils中没有accessConstructor((。这种方法从Spring v5开始就存在。查看pom.xml，也许某些依赖项正在使用小于5的Spring版本

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 => 最有可能的是，您会看到两个版本。然后你应该排除任何小于v5的Spring依赖项。
