直接用Google搜索，发现库jar文件位于您的web应用程序文件夹（webcontent / lib）中，该文件夹与apache服务器servlet容器lib文件不匹配。 如果您将任何tomcat jar文件复制到您的Web应用程序文件夹中，只需删除它们，因为它已经存在于tomcat服务器库中。

绝对是带有编译代码的库文件错误匹配以及容器有什么..

删除你的应用程序并取出你添加到tomcat lib文件夹中的所有jar文件。你的库文件中的一个与Tomcat库文件不兼容。一旦显示tomcat主页，添加你的应用程序并继续库文件一个接一个..

您需要将tomcat jasper jar添加到类路径中 http://grepcode.com/snapshot/repo1.maven.org/maven2/org.apache.tomcat/tomcat-jasper/7.0.55/
我遇到了同样的问题但是使用嵌入式tomcat并通过在pom文件中添加以下依赖来修复它
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
