重新启动tomcat，然后重新发布您的应用。如果再来一次。看看你的tomcat，看看这个jar是否遗漏了commons-digester3-3.2.jar。

你的应用程序是一个maven web应用程序，如果那个jar丢失了。在pom.xml。

中添加这些行

<dependency>
    <groupId>commons-digester</groupId>
    <artifactId>commons-digester</artifactId>
    <version>2.1</version>
</dependency>

最后，建议使用Tomcat 7.

我的maven webapp项目在tomcat7上成功启动但是tomcat8失败了，为什么？
