**错误解决**  
`pom.xml`两个依赖servlet-api、jsp需要限定作用域，在dependency标签中加上 `<scope>provided</scope>`

<dependency>
                <groupId>javax.servlet</groupId>
                <artifactId>javax.servlet-api</artifactId>
                <version>3.1.0</version>
                <scope>provided</scope>
            </dependency>
    
            <dependency>
                <groupId>org.glassfish.web</groupId>
                <artifactId>javax.servlet.jsp</artifactId>
                <version>2.2.2</version>
                <scope>provided</scope>
            </dependency>

**如果还未解决**  
可能是web.xml问题，这个只要好好检查一下代码就可以解决，网上大部分都是这个的问题。

servlet-mapping中的配置问题

<url-pattern>/</url-pattern>

**最后**  
可能导入的jar包存在兼容问题。  
主要在`servlet-api`这个包, 或者`jsp`这个包。
