1、检查jdk版本，删除编译的文件夹，clean tomcat服务器和project，重新进行编译，如果错误仍然抛出，则说明不是jdk版本的问题。

2、检查pom.xml中jar包引入的版本信息，删除多余无用的jar包。

3、检查jar包冲突：

        <dependency>
            <groupId>javax.servlet.jspgroupId>
            <artifactId>jsp-apiartifactId>
            <version>2.1version>
        dependency>

    该jar在tomcat中存在，如果在pom.xml中配置，则会引起jar包冲突，可删除该配置，如果是一般的web项目，删除项目中引入的这个jar包即可。
