有什么建议吗？

不确定你现在是否已经解决了。大多数情况下这个问题是由于依赖项中的版本tomcat jar文件不正确。

我今天遇到了类似的问题，我采取了解决问题的方法：

在“IntelliJ IDEA”maven项目窗口中，有一个“Show Dependencis”按钮，单击它。
搜索“servlet”，找出所有未执行的servlet jar，将其排除。

pom.xml会自动添加以下行

<exclusions>
    <exclusion>
        <artifactId>servlet-api-2.5</artifactId>
        <groupId>org.mortbay.jetty</groupId>
    </exclusion>
</exclusions>

你也可以mvn dependency:tree获取列表，并找出不正确的tomcat依赖性。使用IDE会更快。
