spring,springmvc,mybatis基本整合（一）--xml文件配置方式(1)

**这个整合。仅仅是最主要的整合，而且是xml配置文件的方式之中的一个，即当中的mybatis是採用非mapper接口的方式。（第二遍採用mapper接口方式。第三遍採用注解的方式；第四篇採用注解基于maven的方式）。记录在这里，以免下次忘记时留作备用。

===================================================================================================**

一。总体结构





二，所需jar包：

实质上并不须要所有导入，这里为了方便就所有导入啦。

（1）spring4所有jar包

（2）mybatis所有jar包

（3）mybatis-spring.jar整合须要这个包，如今spring官方已经不提供整合的jar，所以须要另外下载mybatis官方提供的整合jar。

（4）这里使用数据源dbcp.jar,依赖pool.jar,因此也须要导进来。

以及数据库连接驱动jar也须要。

三，整合spring。springmvc和mybatis配置

mybatis配置文件Configuration.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

  <mappers>
    <mapper resource="com/mapc/conf/mybatisconf/Student.xml"/>
  </mappers>

</configuration>

mybatis Mapper的配置文件：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE mapper
    PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

        <id column="ID" jdbcType="VARCHAR" property="id"/>
        <result column="NAME" jdbcType="VARCHAR" property="name"/>
        <result column="AGE" jdbcType="INTEGER" property="age"/>
    </resultMap>
    <select id="queryStudentList" resultMap="studentResultMapper">
        select ID,NAME,AGE from STUDENT
    </select>
</mapper>

四，java源代码

———-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;
/**
 * 持久层详细实现类之中的一个
 * @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;
/**
 * 学生业务的详细实现类
 * @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。执行測试（利用别的測试手段也得）

菜鸟首次整合，尽管非常easy，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，还是实践可以验证整理。

多实践，多思考，谨记！
