1. Eclipse解决servlet.api缺失的方法参考此处

2. 通过配置pom.xml里依赖来添加servlet.api

在里面添加如下代码保存后错误立刻消失

 <dependencies>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.5</version>
        <scope>provided</scope>
    </dependency>
  </dependencies>

3. 运行Web工程

依赖范围参考此处
- 由于以依赖范围是provide,所以部署后Tomcat容器下并没有servlet

  • 依赖范围改为complied与其对比

The "javax.servlet.http.HttpServletRequest" class is part of the Java Servlet API, which is used for handling HTTP requests and responses in Java web applications. To resolve the issue of "HttpServletRequest not found", you need to make sure that you have included the necessary libraries in your project. Here are a few steps you can follow to resolve this issue: 1. Check your project dependencies: Make sure you have added the servlet API dependency in your project. If you are using a build tool like Maven, add the following dependency to your pom.xml file: ```xml <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>4.0.1</version> <scope>provided</scope> </dependency> ``` 2. Verify your Servlet container: Ensure that you are using a Servlet container that supports the Servlet API. Common examples include Apache Tomcat, Jetty, or GlassFish. Make sure the container is properly configured and running. 3. Clean and rebuild your project: Sometimes, IDEs may not properly recognize or import classes. Try cleaning and rebuilding your project to ensure that all dependencies are correctly resolved. 4. Import the required package: If you are using an IDE like Eclipse or IntelliJ, make sure to import the "HttpServletRequest" class by adding the following import statement at the top of your Java file: ```java import javax.servlet.http.HttpServletRequest; ``` By following these steps, you should be able to resolve the "HttpServletRequest not found" issue. If you continue to encounter any problems, please provide more details about your project setup and any error messages you are receiving.
