Question

大家好，我在 tomcat 中部署应用程序时遇到以下错误。我在 eclipse 中配置了 tomcat，tomcat 版本为 8.5.3，java 版本为 1.8。

在我的目标war的lib文件夹中还包含我在pom中声明的所有jar。我尝试清理和清理tomcat的工作目录，但仍然遇到相同的错误。

我的web.xml如下

<servlet>
<servlet-name>spitter</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- if we want to use custom configuration file use init param attribute and set contextConfigLocation parameter to our 
custom file otherwise it will look forservletname-servlet.xml file in WEB-INF location -->
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spitter</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<!-- <filter>
<filter-name>spingSecurityFilterChain</filter-name>
<filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
</filter> -->
</web-app>

有人可以帮我解决这个问题吗？提前致谢

我有这个问题，我的 spring boot 项目也有一个依赖项，另一个 jar 库包含

<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>5.0.15.RELEASE</version>
</dependency>

虽然我的spring boot项目的版本是5.1.12.RELEASE，但我认为存在jar冲突问题。我将 spring-core 5.0.15.RELEASE 的版本升级到 5.1.12.RELEASE。 然后问题就解决了。

请确保所有版本的 jar 都匹配。
