我有一个基于spring framework 3的maven webapp，当我maven-jetty-plugin通过运行命令在jetty上运行应用程序时mvn -e clean jetty:run，它运行正常，但是当我tomcat-maven-plugin通过运行命令在tomcat上运行它时，mvn -e clean tomcat:run它给了我以下异常：

以下是我在web.xml配置中配置过滤器的方式：

<!-- Filters -->
<filter>
    <filter-name>sitemesh</filter-name>
    <filter-class>com.opensymphony.sitemesh.webapp.SiteMeshFilter</filter-class>
</filter>
<filter>
    <filter-name>methodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>sitemesh</filter-name>
    <url-pattern>/*</url-pattern>
    <dispatcher>REQUEST</dispatcher>
</filter-mapping>
<filter-mapping>
    <filter-name>methodFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

有人可以帮助我理解为什么会出现此错误并帮助我解决它吗？

谢谢。

  1. 先看第一个confluence servlet插件，ClassCastException问题
<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>servlet-api</artifactId>
   <version>2.5</version>
   <scope>provided</scope>
</dependency>

请注意

<scope>provided</scope>

然后你需要检查依赖树，排除其他 servlet-api
