Java 我的maven webapp项目在tomcat7上成功启动，但tomcat8失败，为什么？

严重: 子容器在启动期间失败

重新启动tomcat，然后重新发布应用程序。如果它再次出现。查看您的tomcat，看看是否缺少

commons-digester3-3.2.jar

这个jar

如果缺少jar，那么您的应用程序就是maven web应用程序。将这些行添加到

pom.xml

中

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

最后，推荐使用Tomcat7
