用IDEA创建Servlet
选择Use module compile output path,将Output path和Test output path都选择为刚才创建的classes路径下，然后点击下方的Apply
同时配置Tomcat，Run -> Edit Configuration -> 点击左上角“+”号 -> “Tomcat Server” -> “Local”
在"Name"处输入服务名，点击"Application server"后面的"Configure…"，弹出Tomcat Server窗口，选择本地安装的Tomcat目录，点击 Apply -> OK
import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; /** * @author ZhouYanXiang */ public class Servlet1 extends HttpServlet { @Override protected void doGet(HttpServletRequest request, HttpServletResponse response) { System.out.println("----调用doGet()方法----"); } @Override protected void doPost(HttpServletRequest request, HttpServletResponse response) { System.out.println("----调用doPost()方法----"); //调用doGet方法 doGet(request,response); } }
