1.导入jar包，见附件，整体架构见附件。

2.配置web.xml

    <!--站点名-->
    <display-name>mvc</display-name>

    <!--指定spring配置文件-->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:application-context.xml</param-value>
    </context-param>

jdbc.validationQuery =select 1 from alyssa_student
jdbc.testOnBorrow =true
jdbc.testWhileIdle =true

6.编写mybatis.xml

<mapper namespace="com.nwsuaf.ssp.domain">

    <resultMap type="com.nanjing.test.domain.Student" id="studentResult">
        <result property="id" column="id"/>
        <result property="name" column="name_alyssa"/>
        <result property="birth" column="birth_alyssa"/>
        <result property="score" column="score_alyssa"/>
    </resultMap>

    <select id="selectAllStudent" resultMap="studentResult">
        select *
        from alyssa_student
    </select>

    <insert id="insertStudent" parameterType="student">
        insert into alyssa_student(name_alyssa,birth_alyssa,score_alyssa)
        values (#{name},#{birth},#{score})
    </insert>

    <update id="updateStudent" parameterType="student">
        update alyssa_student set name_alyssa=#{name},
        birth_alyssa=#{birth},score_alyssa=#{score}
    </update>
</mapper>

8.编写controller类

package com.nanjing.test.action;

import com.nanjing.test.domain.Student;
import com.nanjing.test.service.StudentService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

import java.util.HashMap;
import java.util.List;
import java.util.Map;

@Controller
public class StudentController {
    @Autowired
    private StudentService studentService;

    @RequestMapping(value = "/student/showlist")
    public ModelAndView showlist() {
        List<Student> studentList = studentService.selectAllStudent();
        Map map = new HashMap();
        map.put("studentList", studentList);
        return new ModelAndView("student_list", map);
    }

    @RequestMapping(value = "/student/saveStudent")
    public String saveStudent(Student student) {
        studentService.insertStudent(student);
        return "redirect:/student/showlist";
    }

}

9.编写实体student类

package com.nanjing.test.domain;

public class Student {
    private int id;
    private String name;
    private String birth;
    private String score;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getBirth() {
        return birth;
    }

    public void setBirth(String birth) {
        this.birth = birth;
    }

    public String getScore() {
        return score;
    }

    public void setScore(String score) {
        this.score = score;
    }
}

10.编写StudentDao接口

package com.nanjing.test.dao;

import com.nanjing.test.domain.Student;
import java.util.List;

public interface StudentDao {
    public List<Student> selectAllStudent();

    public void insertStudent(Student student);

    public void updateStudent(Student student);
}

11.编写studentDaoImpl实现类

package com.nanjing.test.dao;

import com.nanjing.test.domain.Student;
import org.mybatis.spring.SqlSessionTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;

import java.util.List;

@Repository
public class StudentDaoImpl implements StudentDao{
    @Autowired
    private SqlSessionTemplate sqlSessionTemplate;


    public List<Student> selectAllStudent() {
        return sqlSessionTemplate.selectList("selectAllStudent");
    }

    public void insertStudent(Student student) {
        sqlSessionTemplate.insert("insertStudent", student);
    }

    public void updateStudent(Student student) {
        sqlSessionTemplate.update("updateStudent", student);
    }
}

12.编写StudentService接口

package com.nanjing.test.service;

import com.nanjing.test.domain.Student;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public interface StudentService {
    public List<Student> selectAllStudent();

    public void insertStudent(Student student);

    public void updateStudent(Student student);
}

13.编写StudentServiceImpl实现类

import java.util.List;

@Service
public class StudentServiceImpl implements StudentService {

    @Autowired
    private StudentDao studentDao;

    public List<Student> selectAllStudent() {
        return studentDao.selectAllStudent();
    }

    public void insertStudent(Student student) {
        studentDao.insertStudent(student);
    }

    public void updateStudent(Student student) {
        studentDao.updateStudent(student);
    }
}

7.编写student_list.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>

    <title>学生列表</title>
</head>
<body>
<form action="${pageContext.request.contextPath}/student/saveStudent" method="post">

        <tr>
            <td><input type="submit" value="提交"></td>
        </tr>
    </table>
</form>

</br>
<table>
    <tr>
        <th>姓名</th>
        <th>生日</th>
        <th>分数</th>
    </tr>
    <c:forEach items="${studentList}" var="student" varStatus="status">
