1.声明式开发：

web.xml:


     
         
      
       lmj
          
              
       
        MyServlet
               
       
        com.lmj.MyServlet
           
          
              
       
        MyServlet
               
       
        /hello
           
          
              
       
        index.jsp

MyServlet

public class MyServlet extends HttpServlet {    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {          response.getWriter().write("hello world");    }    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {         this.doPost(request,response);    }}

pom.xml中添加javax.servlet依赖：


     
         
      
       4.0.0
          
      
       com
          
      
       servletTest
          
      
       1.0-SNAPSHOT
      
          
           
               
        
         javax.servlet
                
        
         servlet-api
                
        
         3.0-alpha-1
                
        
         provided

2.注解式开发：

web.xml：

MyServlet：

@WebServlet(name = "myServlet", urlPatterns = "/lmj")public class MyServlet extends HttpServlet {    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {          response.getWriter().write("hello world");    }    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {         this.doPost(request,response);    }}
