【问题描述】：

我想创建简单的 Spring MVC 项目。

我得到了：

上下文初始化失败 org.springframework.beans.factory.BeanCreationException：创建名为“org.springframework.validation.beanvalidation.LocalValidatorFactoryBean#0”的bean时出错：调用init方法失败；嵌套异常是 java.lang.LinkageError：加载程序约束违规：解析方法“org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory;”时当前类 org/slf4j/LoggerFactory 的类加载器（org/apache/catalina/loader/WebappClassLoader 的实例）和已解析类 org/ 的类加载器（org/apache/catalina/loader/StandardClassLoader 的实例） slf4j/impl/StaticLoggerBinder，LoggerFactory类型有不同的Class对象

我不明白为什么会这样。以及如何解决这个问题。

更新：

mvn -Dverbose dependency:tree之后的输出：

有什么建议吗？

【问题讨论】：

你有没有机会在多个地方都有 slg4j jar？
@almasshaikh 我误解了你的意思。
mvn -Dverbose dependency:tree 会告诉您在构建中是否有不同的 jar 可能会出现冲突版本。寻找日志罐子。
@bjoernhaeuser 我更新了问题。
@nazar_art 您使用的是哪个容器？似乎您的容器附带了其中一个日志 jar 的冲突版本。

【解决方案1】：

解决方案已清理 - Tomcat 上的 webapps 文件夹。

我删除了已部署的旧项目。现在它工作正常。

它对我的应用程序产生了一些奇怪的影响。
