Add a SPRINGMVC configuration file

Under Resources/spring file, create a new Springmvc.xml file

Springmvc.xml

The SSM framework has been built, and the following tests are mybatis for reverse engineering.

Production of PO, mapper related documents, look at the picture.

How to generate by MyBatis reverse engineering, see links. Subsequent updates

Test class MyBatis Framework test

Create the package com.flyme.service below Src/test/java, where you create the Courseserviceimpltest test class to test the MyBatis framework for success.

Courseserviceimpltest.java

package com.flyme.service;import com.flyme.po.Course;import org.junit.Before;import org.junit.Test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class CourseServiceImplTest {    private ApplicationContext applicationContext;    @Before    public void setUp() throws Exception {        applicationContext = new ClassPathXmlApplicationContext(new String[]{"spring/applicationContext-dao.xml",                "spring/applicationContext-service.xml"});    }    @Test    public void findById() throws Exception {        CourseService courseService = (CourseService) applicationContext.getBean("courseServiceImpl");        Course course = courseService.findById(1);        System.out.println(course.toString());    }}

Run the FindByID () method, which appears to prove the success of the build

SPRINGMVC Framework Test Admincontroller.java

Create Admincontroller.java under the Src/main/java,com.flyme.controller package to measure the success of the SPRINGMVC framework.

package com.flyme.controller;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;@WebServlet("/myController")public class AdminController extends HttpServlet {    @Override    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {        doPost(req, resp);    }    @Override    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {        String name = req.getParameter("name");        req.setAttribute("name", name);        System.out.println(name);        req.getRequestDispatcher("index.jsp").forward(req, resp);    }}

idex.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>

Run the project

Configure Tomcat

Finally select OK, you can.

Browser input http://localhost:8010/(because I changed the port number, flexible application)

Input: "I Am"
