Eclipse报错The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

新建Maven后，Eclipse报错：The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path.

解决办法如下：

1 打开Maven中央仓库

2 搜索框输入servlet进行搜索

3 选择第一个结果：Java Servlet API

4 查看某个版本依赖

5 在Maven项目pom.xml中添加该依赖

<!-- https://mvnrepository.com/artifact/javax.servlet/javax.servlet-api -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>4.0.1</version>
    <scope>provided</scope>
</dependency>
