### 解决方法一 ###

加上标签 `<scope>provided</scope>`

<dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>
    
            <version>3.1.0</version>
    
            <scope>provided</scope>
        </dependency>

网上大多这样说，原因还可能是

<dependency>
                <groupId>javax</groupId>
                <artifactId>javaee-api</artifactId>
                <version>7.0</version>
                
            </dependency>

也需要加上provided  
如果你的还报这个错，请找找别的jar包的servlet的冲突。jar包冲突可以删掉或者按照上述操作都可以

这里指向代码中的某一行，代码原因导致的，遇到这个问题需要具体情况具体分析，看看详细的报错，别一味百度。
