The reason: The project automatically servlet-api and Tomcat Servlet-api conflict,

Workaround:

To include the scope option in the Pom.xml file:

        <dependency>            <groupId>javax.servlet</groupId>            <artifactid>servlet-api</ artifactid>            <version>2.4</version>            <scope>provided</scope>        </ Dependency>
        <dependency>
<groupId>javax.servlet</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
<scope>provided</scope>
</dependency>
