1.准备
这段时间学习了Spring和Mybatis的知识，我们知道持久层的 mapper,dao都需要spring进行管理， 需要spring通过单例的方式管理SqlSessionFactory，spring和mybatis整合生成代理对象使用sqlsessionFactory创建sqlsession；练习全部jar （Spring+Mybatis+Spring-mybatis整合包）下载 ：
http://download.csdn.net/detail/lablenet/9385114
demo数据准备 ：
(1) 创建一个客户表 ：
[sql] view plain copy print?--客户表
CREATE TABLE F_CLIENT(
ID NUMBER(12) PRIMARY KEY,--用户编号
USERNAME VARCHAR2(20) NOT NULL,--用户姓名
CLIENT_CERTIFICATE_NO VARCHAR2(20) NOT NULL UNIQUE,--证件号码
BORN_DATE DATE,--出生日期
FAMILY_REGISTER_ADDRESS VARCHAR2(200),--家庭住址
NOW_ADDRESS VARCHAR2(200) NOT NULL,--现在住址
CONTACT_MODE VARCHAR2(50) NOT NULL,--联系方式
URGENCY_CONTACT_MODE VARCHAR2(50) NOT NULL,--紧急联系方式
CREATE_DATE DATE NOT NULL--创建时间
);
--客户表CREATE TABLE F_CLIENT( ID NUMBER(12) PRIMARY KEY,--用户编号 USERNAME VARCHAR2(20) NOT NULL,--用户姓名 CLIENT_CERTIFICATE_NO VARCHAR2(20) NOT NULL UNIQUE,--证件号码 BORN_DATE DATE,--出生日期 FAMILY_REGISTER_ADDRESS VARCHAR2(200),--家庭住址 NOW_ADDRESS VARCHAR2(200) NOT NULL,--现在住址 CONTACT_MODE VARCHAR2(50) NOT NULL,--联系方式 URGENCY_CONTACT_MODE VARCHAR2(50) NOT NULL,--紧急联系方式 CREATE_DATE DATE NOT NULL--创建时间);
(2) 初始化数据 ：
[sql] view plain copy print?insert into f_client(id,username,client_certificate_no,born_date,family_register_address,now_address,contact_mode,urgency_contact_mode,create_date) values (14,
'yuan','311209070127',to_date('1993-03-12','yyyy-mm-dd'),'河南省焦作市','河南省河南理工大学','150000000','110',sysdate);
insert into f_client(id,username,client_certificate_no,born_date,family_register_address,now_address,contact_mode,urgency_contact_mode,create_date) values(
15,'yang','311209070126',to_date('1993-04-12','yyyy-mm-dd'),'河南温县','河南理工大学','3987321','110',sysdate);
insert into f_client values(
16,'yang','311209070129',to_date('1997-04-12','yyyy-mm-dd'),'河南新乡','河南理工大学','3987321','110',sysdate);
insert into f_client(id,username,client_certificate_no,born_date,family_register_address,now_address,contact_mode,urgency_contact_mode,create_date) values (14,'yuan','311209070127',to_date('1993-03-12','yyyy-mm-dd'),'河南省焦作市','河南省河南理工大学','150000000','110',sysdate);insert into f_client(id,username,client_certificate_no,born_date,family_register_address,now_address,contact_mode,urgency_contact_mode,create_date) values( 15,'yang','311209070126',to_date('1993-04-12','yyyy-mm-dd'),'河南温县','河南理工大学','3987321','110',sysdate); insert into f_client values( 16,'yang','311209070129',to_date('1997-04-12','yyyy-mm-dd'),'河南新乡','河南理工大学','3987321','110',sysdate);(3) 客户表 po

整合图解 ：
下面我们使用一个例子来说明 ：
场景描述 ： 通过客户id查询客户信息 ；
（1）dao层
dao接口[java] view plain copy print?public interface ClientDao {
FClient findClientById(int id);
}
public interface ClientDao { FClient findClientById(int id);}dao接口实现 :
注意 ： 在这里我们让dao实现接口继承SqlSessionDaoSupport (在spring-mybatis整合包中 org.mybatis.spring.support.SqlSessionDaoSupport)，则在dao接口实现中不需要sqlsessionFactory属性了；就不用了在注入sqlSessionFactory了；
[java] view plain copy print?public class ClinetDapimpl extends SqlSessionDaoSupport implements ClientDao {
/*
* 原始的sqlSessionFactory的注入方式
* private SqlSessionFactory sqlSessionFactory;
public ClinetDapimpl(SqlSessionFactory sqlSessionFactory) {
super();
this.sqlSessionFactory = sqlSessionFactory;
}*/
@Override
public FClient findClientById(int id) {
SqlSession session = this.getSqlSession();
FClient client = (FClient) session.selectOne("cn.labelnet.dao.ClientDao.findClientById",id);
return client;
}
}
public class ClinetDapimpl extends SqlSessionDaoSupport implements ClientDao { /* * 原始的sqlSessionFactory的注入方式 * private SqlSessionFactory sqlSessionFactory; public ClinetDapimpl(SqlSessionFactory sqlSessionFactory) { super(); this.sqlSessionFactory = sqlSessionFactory; }*/ @Override public FClient findClientById(int id) { SqlSession session = this.getSqlSession(); FClient client = (FClient) session.selectOne("cn.labelnet.dao.ClientDao.findClientById",id); return client; } }（2）Clientmap.xml
操作数据库；[html] view plain copy print?<?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">
<mapper namespace="cn.labelnet.dao.ClientDao">
<select id="findClientById" parameterType="int" resultType="cn.labelnet.po.FClient">
select * from f_client where id=#{value}
</select>
</mapper>
<?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"> <mapper namespace="cn.labelnet.dao.ClientDao"> <select id="findClientById" parameterType="int" resultType="cn.labelnet.po.FClient"> select * from f_client where id=#{value} </select></mapper>（3）SqlMapConfig.xml
在之前的练习中，我们在这里加载数据源，但是在整合中我们将数据源加载交给了spring的ApplicationContext.xml[html] view plain copy print?<?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="cn/lablenet/dao/sqlmap/ClientMap.xml"/>
<!-- 加载mapper映射文件 -->
<!-- <mapper resource="cn/labelnet/mapper/ClientMapper.xml" /> -->
</mappers>
</configuration>
<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration> <mappers> <mapper resource="cn/lablenet/dao/sqlmap/ClientMap.xml"/> <!-- 加载mapper映射文件 --> <!-- <mapper resource="cn/labelnet/mapper/ClientMapper.xml" /> --> </mappers> </configuration>
（4）ApplicationContext.xml
注意 ：1）数据源加载用的是 org.apache.commons.dbcp.BasicDataSource ；2）配置sqlsessionFactory 用的是 org.mybatis.spring.SqlSessionFactoryBean ；
3）配置dao的接口实现，为其注入sqlSessionFactory ；

整合图解 ：
示例 ：上面的场景不变，采用上面的场景实现
（1）Mapper.xml实现
[html] view plain copy print?<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE mapper

（4）Applicationcontext.xml
注意 ：1）数据源加载用的是 org.apache.commons.dbcp.BasicDataSource ；2）配置sqlsessionFactory 用的是 org.mybatis.spring.SqlSessionFactoryBean ；
3）通过MapperFactoryBean 实现 创建代理对象用的是 org.mybatis.spring.mapper.MapperFactoryBean

再此陷入纠结中；开始的时候，自己的spring , mybatis ,spring-mybatis的整合包是自己这里复制哪里粘贴的，导致很多重复包，经过使用上面的全部整合包，解决了；
还有一个问题 ：
问题 ： mapper多的话，需要配置多个mapper
解决：mapper批量扫描，从mapper包中扫描出mapper接口，自动创建mapper对象
4.Mapper代理整合 bean扫描实现
整合图解 ：
1） bean配置
Mapper.xml 和 mapper.java一样，在这里就只配置下ApplicationContext.xml文件

（2） 重点是 ：
[html] view plain copy print?<!-- mapper批量扫描：
从mapper包中扫描出mapper接口，自动创建代理对象 并且在spring容器中注册；
遵循规范：将mapper.java和mapper.xml映射文件名称保持一致，且在一个目录中，

<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!-- 扫描的包名 -->

<!-- mapper批量扫描： 从mapper包中扫描出mapper接口，自动创建代理对象 并且在spring容器中注册； 遵循规范：将mapper.java和mapper.xml映射文件名称保持一致，且在一个目录中， 自动扫描出来的mapper的bean的 id为mapper类名首字母小写；--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 扫描的包名 --> <property name="basePackage" value="cn.labelnet.mapper"></property> <!-- Sqlsession --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> </bean>
注意几点 ：
1）扫描bean不需要 设置ID ，使用的时候是扫描出来的mapper的类名且首字母小写； 2）扫描bean使用的是 org.mybatis.spring.mapper.MapperScannerConfigurer；
3）配置SqlSessionFactory的时候使用 ：value为sqlSessionFactory的bean的id ;
