IntelliJ IDEA 2017版 spring-boot 拦截器的操作三种方式

一、注解方式

 @WebServlet(urlPatterns = "/myServlet")
 public class MyServlet extends HttpServlet {

     // 访问方式: http://localhost:8080/demo/myServlet

     private static final long serialVersionUID = -7864798058212193346L;

     @Override
     protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
         response.getWriter().print("My Servlet Hello World!!!");
         response.getWriter().flush();
         response.getWriter().close();
     }

     @Override
     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
         this.doGet(request, response);
     }
 }

二、配置Bean+@Controller

 public class HeServlet extends HttpServlet {

     private static final long serialVersionUID = 9040678112053909135L;

     @Override
     protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
         response.getWriter().print("He Servlet Hello World!!!");
         response.getWriter().flush();
         response.getWriter().close();
     }

     @Override
     protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
         this.doGet(request, response);
     }

 }

三、配置Bean+@Configuration
