myBatis-config.xml文件

通过package, 可以直接指定package的名字， mybatis会自动扫描你指定包下面的javabean,并且默认设置一个别名，**默认的名字为非限定类名来作为它的别名。**

## 编写Dao以及实现 ##

接口

package zhongfucheng.dao;import zhongfucheng.entity.Dept;/** * Created by ozc on 2017/8/8. */public interface DeptDao {    Dept selectDept(Integer deptId);    int insertDept(Dept dept);}
    
    import zhongfucheng.entity.Dept;
    
    /** * Created by ozc on 2017/8/8. */
    
    public interface DeptDao {
        
        Dept selectDept(Integer deptId);
        int insertDept(Dept dept);
    }

实现：

package zhongfucheng.dao.impl;import org.mybatis.spring.SqlSessionTemplate;import org.springframework.stereotype.Repository;import zhongfucheng.entity.Dept;import javax.annotation.Resource;/** * Created by ozc on 2017/8/8. */@Repository("deptDao")public class DeptDaoImpl implements zhongfucheng.dao.DeptDao {    @Resource    private SqlSessionTemplate sqlSessionTemplate;    /**     * 根据部门编号查询部门信息     * @param deptId 部门编号     * @return 部门信息     */    @Override    public Dept selectDept(Integer deptId){        Dept dept=    sqlSessionTemplate.selectOne("zhongfucheng.entity.DeptMapper.selectDept", deptId);        return dept;    }    /**     * 添加部门信息     * @param dept 部门信息     * @return 添加成功的记录数     */    @Override    public int insertDept(Dept dept){        System.out.println("------dao.dept:"+dept);        return sqlSessionTemplate.insert("zhongfucheng.entity.DeptMapper.insertDept", dept);    }}
    
    import org.mybatis.spring.SqlSessionTemplate;
    import org.springframework.stereotype.Repository;
    import zhongfucheng.entity.Dept;
    
    import javax.annotation.Resource;
    
    /** * Created by ozc on 2017/8/8. */
    @Repository("deptDao")
    public class DeptDaoImpl implements zhongfucheng.dao.DeptDao {
        
    
        @Resource
        private SqlSessionTemplate sqlSessionTemplate;
    
        /**     * 根据部门编号查询部门信息     * @param deptId 部门编号     * @return 部门信息     */
        @Override
        public Dept selectDept(Integer deptId){
        
            Dept dept=    sqlSessionTemplate.selectOne("zhongfucheng.entity.DeptMapper.selectDept", deptId);
            return dept;
        }
        /**     * 添加部门信息     * @param dept 部门信息     * @return 添加成功的记录数     */
        @Override
        public int insertDept(Dept dept){
        
            System.out.println("------dao.dept:"+dept);
            return sqlSessionTemplate.insert("zhongfucheng.entity.DeptMapper.insertDept", dept);
        }
    }

## 编写Action ##

package zhongfucheng.action;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import zhongfucheng.dao.impl.DeptDaoImpl;import zhongfucheng.entity.Dept;import javax.annotation.Resource;/** * Created by ozc on 2017/8/8. */@Controller@RequestMapping(value="/dept")public class DeptAction {    @Resource    private DeptDaoImpl deptDao;    @RequestMapping(value="/insert")    public String insert(Dept dept){        System.out.println("---action.dept:"+dept);        deptDao.insertDept(dept);        return "forward:/jsp/main.jsp";    }}
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import zhongfucheng.dao.impl.DeptDaoImpl;
    import zhongfucheng.entity.Dept;
    
    import javax.annotation.Resource;
    
    /** * Created by ozc on 2017/8/8. */
    @Controller
    @RequestMapping(value="/dept")
    public class DeptAction {
        
        @Resource
        private DeptDaoImpl deptDao;
    
        @RequestMapping(value="/insert")
        public String insert(Dept dept){
        
    
            System.out.println("---action.dept:"+dept);
            deptDao.insertDept(dept);
            return "forward:/jsp/main.jsp";
        }
    }

## 测试SSI整合 ##

index.jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><html><head></head><body>    <form action="dept/insert.action" method="post">        名称：<input type="text"   name="deptName"><br>         地址：<input type="text" name="deptAddress"><br>        <input type="submit" value="ok">    </form></body></html>
    <html>
    <head>
    </head>
    <body>
        <form action="dept/insert.action" method="post">
            名称：<input type="text"   name="deptName"><br> 
            地址：<input type="text" name="deptAddress"><br>
            <input type="submit" value="ok">
        </form>
    </body>
    </html>

main.jsp页面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><html><head></head><body> this is main jsp</body></html>
    <html>
    <head>
    </head>
    <body>
     this is main jsp
    </body>
    </html>

# 优化 #

如果想要Spring与Mybatis更加完美地结合，**其实我们的Dao并不需要写实现，直接写接口和映射文件就行了，这样一来，我们就可以舍弃DaoImpl了**。

在Spring配置文件中加入以下的代码：

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="sqlSessionFactory" ref="sqlSessionFactory" />                <property name="basePackage" value="zhongfucheng.dao" />    </bean>
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            <property name="sqlSessionFactory" ref="sqlSessionFactory" />
    
            
            <property name="basePackage" value="zhongfucheng.dao" />
        </bean>

我们的映射文件中把命名空间写成是Dao的全路径

//Dao的全路径，那么Spring就会自动帮我们创建对象，注入进去<mapper namespace="zhongfucheng.dao.DeptDao">    <resultMap type="Dept" id="deptResultMap">        <id property="deptId" column="dept_id" />        <result property="deptName" column="dept_name" />        <result property="deptAddress" column="dept_address" />    </resultMap>        <select id="selectDept" parameterType="Integer" resultMap="deptResultMap">                select * from dept where dept_id=#{deptID}    </select>    <insert id="insertDept" parameterType="Dept">        insert into dept(dept_name,dept_address) values(#{deptName},#{deptAddress});    </insert></mapper><mapper namespace="zhongfucheng.dao.DeptDao">
        <resultMap type="Dept" id="deptResultMap">
            <id property="deptId" column="dept_id" />
            <result property="deptName" column="dept_name" />
            <result property="deptAddress" column="dept_address" />
        </resultMap>
    
        
        <select id="selectDept" parameterType="Integer" resultMap="deptResultMap">
            
            select * from dept where dept_id=#{deptID}
        </select>
    
        <insert id="insertDept" parameterType="Dept">
            insert into dept(dept_name,dept_address) values(#{deptName},#{deptAddress});
        </insert>
    
    </mapper>

**在配置工厂的时候，我们可以配置mapperLocations属性，这样一来，我们就不用在Mybatis中逐个加载配置文件了。**

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource" />                <property name="configLocation" value="classpath:myBatis-config.xml" />                        <property name="mapperLocations" value="classpath:zhongfucheng/dao/*.xml"/>    </bean>
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource" />
            
            <property name="configLocation" value="classpath:myBatis-config.xml" />
    
            
            
            <property name="mapperLocations" value="classpath:zhongfucheng/dao/*.xml"/>
        </bean>
