**这个整合,只是最基本的整合,并且是xml配置文件的方式之一,即其中的mybatis是采用非mapper接口的方式。(第二遍采用mapper接口方式;第三遍采用注解的方式;第四篇采用注解基于maven的方式),记录在这里,以免下次忘记时留作备用。
===================================================================================================**
一,整体结构
二,所需jar包:
实质上并不需要全部导入,这里为了方便就全部导入啦。
(1)spring4全部jar包
(2)mybatis全部jar包
(3)mybatis-spring.jar整合需要这个包,现在spring官方已经不提供整合的jar,所以需要另外下载mybatis官方提供的整合jar。
(4)这里使用数据源dbcp.jar,依赖pool.jar,因此也需要导进来。以及数据库连接驱动jar也需要。
三,整合spring,springmvc和mybatis配置

mybatis Mapper的配置文件:

<select id="queryStudentList" resultMap="studentResultMapper">

四,java源码
———-bean
package com.mapc.bean;
/**
* POJO
* @author DC
*
*/
public class Student {
/**
* 学号
*/
private String id;
/**
* 姓名
*/
private String name;
/**
* 年龄
*/
private int age;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
@Override
public String toString() {
return "Student [id=" + id + ", name=" + name + ", age=" + age + "]";
}
}
———-dao以及dao.impl
package com.mapc.dao;
import java.util.List;
import com.mapc.bean.Student;
/**
* 持久层接口
* @author DC
*
*/
public interface StudentDao {
/**
* 查询所有学生
*/
List<Student> queryStudentList();
}
package com.mapc.dao.impl;
import java.util.List;
import org.apache.ibatis.session.SqlSession;
import org.mybatis.spring.SqlSessionTemplate;
import com.mapc.bean.Student;
import com.mapc.dao.StudentDao;
/**
* 持久层具体实现类之一
* @author DC
*
*/
public class StudentDaoImpl implements StudentDao {
private SqlSessionTemplate sqlSessionTemplate;
public void setSqlSession(SqlSessionTemplate sqlSessionTemplate) {
this.sqlSessionTemplate = sqlSessionTemplate;
}
@Override
public List<Student> queryStudentList() {
return sqlSessionTemplate.selectList("Student.queryStudentList");
}
}
————service和service.impl
package com.mapc.service;
import java.util.List;
import com.mapc.bean.Student;
import com.mapc.dao.StudentDao;
/**
* 学生相关的业务接口
* @author DC
*
*/
public interface StudentService {
/**
* 查询学生信息的业务接口方法
*/
public List<Student> queryStudentList();
}
package com.mapc.service.impl;
import java.util.List;
import com.mapc.bean.Student;
import com.mapc.dao.StudentDao;
import com.mapc.service.StudentService;
/**
* 学生业务的具体实现类
* @author DC
*
*/
public class StudentServiceImpl implements StudentService {
/**
* 注入StudentDao
*/
private StudentDao studentDao;
public void setStudentDao(StudentDao studentDao) {
this.studentDao = studentDao;
}
@Override
public List<Student> queryStudentList() {
return studentDao.queryStudentList();
}
}
——–controller页面处理器
package com.mapc.controller;
import java.util.List;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
import com.mapc.bean.Student;
import com.mapc.service.StudentService;
/**
* 学生控制类
* @author DC
*
*/
public class StudentController implements Controller {
/**
* 注入学生业务类
*/
private StudentService studentService;
public void setStudentService(StudentService studentService) {
this.studentService = studentService;
}
@Override
public ModelAndView handleRequest(HttpServletRequest req,
HttpServletResponse resp) throws Exception {
ModelAndView mv=new ModelAndView();
List<Student> list=studentService.queryStudentList();
mv.addObject("studentList",list);
System.out.println("----------------:"+list.toString());
mv.setViewName("showStudentList");
return mv;
}
}
五,数据表
六,运行测试(利用别的测试手段也得)
菜鸟首次整合,虽然很简单,在第一次整合的时候还是出现各种难以预料的错误的。为了更加清晰这里面的情况,整合了第二次,还是实践能够验证整理。多实践,多思考,谨记!
spring,springmvc,mybatis基本整合(一)--xml文件配置方式(1)
