取名为ServletTest（也可以自己自定义名字），点击create；

创建后如下：

右键项目，添加框架支持

找到Web Application，在前面打勾

![7f61b9fb99234700b78da49632b27414.png][]

点OK，之后就会出现一个web文件夹

![bc52f24e7c3640a8a96b825f5e81a6c1.png][]

右键WEB-INF，点new,创建一个Directory，命名为lib![ecc108b37a964fd89c2baf3cbbc05b2a.png][]

![a4c8ba2461d3490f9e6d13fb1adfcbb2.png][]

将servlet-api.jar文件（可以在tomcat的lib文件夹中找到）复制到这个路径下

![2ff7f873cd7845bd93acb34a72c73aa6.png][]

右键这个文件，添加到Library中![daba1a5fb06c45d1aafd816ca9ed164a.png][]

![a89521e5344a4d83952981cb6c54d153.png][]

![b9a5597f61814874bc2124a203c80fed.png][]

这样就可以了

在右上角找到这个配置tomcat![633430a1a88b4b938a4ef766660610a7.png][]

点击加号

![000f68fcce8e47fdb1ae146b345bdd94.png][]

找到Tomcat Server 里的Local

![cd99a8b96f2341d2a3d4ba69726e807d.png][]

在Configure找到你的Tomcat路径，（如果有跟我一样的提示，直接点右边的Fix就可以，然后再点Apply,点OK）然后点OK

![a7a7e9b9d342499b888a4fafabc644be.png][]

![9017500a3b4544b6996be2e18df081d2.png][]右键src,新建一个包，命名为Servlet

![a5607ac7b7154684acd225197c6c7c02.png][]

右键Servlet包，新建ServletTest类![64b1cdd337014eb1b28e1b4e926cd180.png][]

输入以下代码

package servlet;
    
    import javax.servlet.ServletConfig;
    import javax.servlet.ServletException;
    import javax.servlet.http.HttpServlet;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.io.IOException;
    import java.io.PrintWriter;
    
    public class ServletTest extends HttpServlet {
       
        private static final long serialVersionUID = 1L;
    
        @Override
        public void init(ServletConfig config) throws ServletException {
            super.init(config);
        }
    
        @Override
        public void service(HttpServletRequest request, HttpServletResponse response) throws IOException {
            response.setContentType("text/html;charset=utf-8");
            PrintWriter out=response.getWriter();
            out.println("<html><body>");
            out.println("第一个Servlet类");
            out.println("</body></html>");
        }
    }

点开web.xml,在<web-app>......</web-app>中间加入以下代码

<servlet>
            <servlet-name>ServletTest</servlet-name>
            <servlet-class>servlet.ServletTest</servlet-class>
        </servlet>
        <servlet-mapping>
            <servlet-name>ServletTest</servlet-name>
            <url-pattern>/servletTest</url-pattern>
        </servlet-mapping>

点击运行按钮，进入下面这个页面

![2407baef82a94ecab530b38f8bccbfeb.png][]

在网址后添加之前在web.xml中设置的

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

![e4d135bb6d39469eb316edb53d91e39c.png][]

现在就成功运行啦![926252edc81d4ab08cdf6d60a4b954ca.png][]
