5.编写jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.1.58:3306/test
jdbc.username=root
jdbc.password=123456
jdbc.maxActive = 20
jdbc.maxIdle =50
jdbc.minIdle=1
jdbc.initialSize =5
jdbc.maxWait =3000
jdbc.validationQuery =select 1 from alyssa_student
jdbc.testOnBorrow =true
jdbc.testWhileIdle =true
 
6.编写mybatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "mybatis-3-config.dtd">
<configuration>
<typeAliases>
<typeAlias alias="student" type="com.nanjing.test.domain.Student"/>
</typeAliases>
<mappers>
<mapper resource="/com/nanjing/test/sqlMapper/sqlMapper-student.xml"/>
</mappers>
</configuration>
 
7.编写sqlMapper-student.xml

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"D:\Idea_Projects\NUSSP\src\com\nwsuaf\ssp\sqlMapper\mybatis-3-mapper.dtd">
<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

package com.nanjing.test.service;
import com.nanjing.test.dao.StudentDao;
import com.nanjing.test.domain.Student;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
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" %>
<html>
<head>
<title>学生列表</title>
</head>
<body>
<form action="${pageContext.request.contextPath}/student/saveStudent" method="post">
<table>
<tr>
<td>姓名：</td>
<td><input name="name" type="text"></td>
</tr>
<tr>
<td>生日：</td>
<td><input name="birth" type="text"></td>
</tr>
<tr>
<td>分数：</td>
<td><input name="score" type="text"></td>
</tr>
<tr>
<td><input type="submit" value="提交"></td>
</tr>
</table>
</form>
</br>
<table>
<tr>
<th>姓名</th>
<th>生日</th>
<th>分数</th>
</tr>
<c:forEach items="${studentList}" var="student" varStatus="status">
<tr>
<td>${student.name}</td>
<td>${student.birth}</td>
<td>${student.score}</td>
</tr>
</c:forEach>
</table>
</body>
</html>
