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
