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。

<?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">

applicationContext.xml

配置数据源，记得去掉myBatis-config.xml的数据源相关配置 
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
    <property name="driverClass" value="com.mysql.jdbc.Driver" />
    <property name="jdbcUrl"
              value="jdbc:mysql://localhost:3306/scm?useUnicode=true&amp;characterEncoding=UTF-8" />
    <property name="user" value="root" />
    <property name="password" value="root" />
</bean>
<!-- 配置session工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <property name="configLocation" value="classpath:myBatis-config.xml" />
    <!--配置扫描式加载SQL映射文件,记得去掉mybatis-config配置-->
<!--    <property name="mapperLocations" value="classpath:zhongfucheng/dao/*.xml"/>-->


</bean>

<!-- 配置事务管理器,管理数据源事务处理 -->
<bean id="transactionManager"
      class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource" />
</bean>
<!-- 配置事务通知 -->
<tx:advice id="advice" transaction-manager="transactionManager">
    <tx:attributes>
        <!-- 默认只处理运行时异常，可加rollback-for="Exception/Throwable"等处理所有异常或包括错误 -->
        <tx:method name="insert*" propagation="REQUIRED"
                   rollback-for="Exception" />
        <tx:method name="update*" propagation="REQUIRED"

        <tx:method name="*" propagation="SUPPORTS" />
    </tx:attributes>
</tx:advice>
<!-- 配置切面织入的范围,后边要把事务边界定在service层 -->
<aop:config>
    <aop:advisor advice-ref="advice"
                 pointcut="execution(* cn.itcast.scm.service.impl.*.*(..))" />
</aop:config>
<!-- 配置SessionTemplate，已封装了繁琐的数据操作 -->
<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
    <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory" />
</bean>

<!-- <context:component-scan base-package="*" /> -->


<!-- 自动扫描组件，要把controller去除，他们是在spring-mvc.xml中配置，如果不去除会影响事务管理。 -->
<context:component-scan base-package="cn.itcast">
    <context:exclude-filter type="annotation"
                            expression="org.springframework.stereotype.Controller" />
</context:component-scan>

<!-- 配置 转换器，对于在basePackage设置的包（包括子包）下的接口类，
如果接口类的全类名在Mapper.xml文件中和定义过命名空间一致，
 将被转换成spring的BEAN，在调用 
    的地方通过@Autowired方式将可以注入接口实例 -->

<!--

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

    &lt;!&ndash;这里包名留意要不要改&ndash;&gt;

编写实体及sql映射游戏文件
SQL脚本

drop database if exists mybatis;
create database mybatis CHARACTER SET UTF8;
use mybatis;

create table dept(

dept_id int primary key auto_increment,
dept_name varchar(50),
dept_address varchar(50)

);

insert into dept(dept_name,dept_address) values(‘研发部一部‘,‘广州‘);
insert into dept(dept_name,dept_address) values(‘研发部二部‘,‘广州‘);
insert into dept(dept_name,dept_address) values(‘研发部三部‘,‘深圳‘);
select * from dept;

实体：

package zhongfucheng.entity;

import java.io.Serializable;

public class Dept implements Serializable {

private Integer deptId;
private String deptName;
private String deptAddress;
public Integer getDeptId() {
    return deptId;
}
public void setDeptId(Integer deptId) {
    this.deptId = deptId;
}
public String getDeptName() {
    return deptName;
}
public void setDeptName(String deptName) {
    this.deptName = deptName;
}
public String getDeptAddress() {
    return deptAddress;
}
public void setDeptAddress(String deptAddress) {
    this.deptAddress = deptAddress;
}
@Override
public String toString() {
    return "Dept [deptId=" + deptId + ", deptName=" + deptName
            + ", deptAddress=" + deptAddress + "]";
}

}

映射文件

<?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">

<resultMap type="Dewww.cungun.compt" id="deptResultMap">
    <id property="deptId" column="dept_id" />
    <result property="deptName" column="dept_name" />
    <result property="deptAddress" column="dept_address" />
</resultMap>
<!-- id和命名空间用来定位SQL语句，parameterType表示参数的类型，resultMap返回类型 -->
<select id="selectDept" parameterType="Integer" resultMap="deptResultMap">
    <!--参数的写法#{deptID} -->
    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>
