搭建基于springmvc，ibatis的工程实现读写分离，配置分离
实现读写分离：
1.spring配置如下：spring-dataResource.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 主数据源 -->
<bean id="myDataSourceMaster" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean>
<!--从数据源-->
<bean id="myDataSourceSlave" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="${jdbc.driverClassName}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean> <bean id="sqlMapClientReader" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="classpath:sql-map-config.xml" />
<property name="dataSource" ref="myDataSourceSlave" />
</bean> <bean id="sqlMapClientWriter" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
<property name="configLocation" value="classpath:sql-map-config.xml" />
<property name="dataSource" ref="myDataSourceMaster" />
</bean> <!-- 操作数据库的基类 -->
<bean id="ibatisBaseDao" class="com.zzcm.ad.common.dao.impl.IbatisBaseDaoImpl">
<property name="ibatisDaoReader">
<bean id="ibatisDaoReader" class="com.zzcm.ad.common.dao.impl.IbatisDaoReaderImpl"></bean>
</property>
<property name="ibatisDaoWriter">
<bean id="ibatisDaoWriter" class="com.zzcm.ad.common.dao.impl.IbatisDaoWriterImpl"/>
</property>
</bean>
</beans>
2.将此配置文件加载到主配置文件 spring-applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- Root Context: defines shared resources visible to all other web components -->
<!-- 加载属性文件 -->
<bean id="propertyConfig" class="com.zzcm.ad.util.spring.PropertyAnnotationPlaceholderConfigurer">
<property name="locations">
<list>
<value>file:${global_config_path}/4gad/jdbc.properties</value>
<value>file:${global_config_path}/4gad/support.properties</value>
</list>
</property>
</bean> <import resource="spring/spring-dataResources.xml"/>
<context:component-scan base-package="com.zzcm.ad"/> <!-- 添加注解驱动 -->
<mvc:annotation-driven/>
<!-- 允许对静态资源文件的访问 -->
<mvc:default-servlet-handler/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
</beans>
3.基本思想：
将读写数据库操作包装到一个基本操作类中，这样子对外操作就是一个基本操作类
因此如下：
基本操作接口：IbatisBaseDao
package com.zzcm.ad.common.dao;
public interface IbatisBaseDao extends IbatisDaoReader,IbatisDaoWriter{
}
读操作接口：IbatisDaoReader
package com.zzcm.ad.common.dao;
import java.util.List;
import java.util.Map;
public interface IbatisDaoReader{
/**
* 根据statementName查询，返回对象
* @param statementName
* @return
*/
public abstract <T> T queryForObject(String statementName);
/**
* 根据statementName，参数obj查询，返回对象
* @param statementName
* @param obj
* @return
*/
public abstract <T> T queryForObject(String statementName, Object obj);
/**
* 根据statementName查询，返回对象集合List
* @param statementName
* @return
*/
public abstract <T> List<T> queryForList(String statementName);
/**
* 根据statementName，参数obj查询,返回对象集合List
* @param statementName
* @param obj
* @return
*/
public abstract <T> List<T> queryForList(String statementName, Object obj);
/**
* 根据statementName，参数obj,返回Map key值查询，返回Map
* @param statementName
* @param obj
* @param keyProperty
* @return
*/
public abstract <T> Map queryForMap(String statementName,Object obj, String keyProperty);
/**
* 根据statementName、参数obj、返回Map key值、返回map value查询，返回Map
* @param statementName
* @param obj
* @param keyProperty
* @param valueProperty
* @return
*/
public abstract <T> Map queryForMap(String statementName,Object obj, String keyProperty,String valueProperty);
}
写操作接口：IbatisDaoWriter
package com.zzcm.ad.common.dao;
import com.zzcm.ad.common.exception.JdbcException;
public interface IbatisDaoWriter{
/**
* 保存一个实体对象
* @param statementName
* @param entity
* @return
* @throws JdbcException
*/
public abstract Integer save(String statementName,Object obj) throws JdbcException;
/**
* 保存
* @param statementName
* @return
* @throws JdbcException
*/
public abstract Integer save(String statementName) throws JdbcException;
/**
* 更新一个实体对象
* @param statementName
* @param entity
* @return
* @throws JdbcException
*/
public abstract int update(String statementName,Object obj) throws JdbcException;
/**
* 更新
* @param statementName
* @param entity
* @return
* @throws JdbcException
*/
public abstract int update(String statementName) throws JdbcException;
/**
* 按照条件删除记录
* @param statementName
* @param paramObj
* @return
* @throws JdbcException
*/
public abstract int delete(String statementName,Object obj) throws JdbcException;
/**
* 按照条件删除记录
* @param statementName
* @return
* @throws JdbcException
*/
public abstract int delete(String statementName) throws JdbcException; }

对外提供的类就是IbatisBaseDaoImpl
配置分离的工程：
jdbc.properties
#数据库连接的方式，请根据你的项目中现有的情况配置
jdbc.driverClassName=com.mysql.jdbc.Driver #数据连接URL，请根据你的项目中现有的情况配置
jdbc.url=jdbc:mysql://idctest.mysql.xxx.com:3306/zzsupport #数据库连接的用户名，请根据你的项目中现有的情况配置
jdbc.username=zzmanager #数据库连接的密码（带“.encrypt”与否都可以，但是带“.encrypt”的密码必须加密），请根据你的项目中现有的情况配置
#jdbc.password.encrypt=2dUGTjehnpU.
jdbc.password=iadMOB-2013@0622)
support.properties
#开发环境
upload.path=D:/apache-tomcat-6.0.30/webapps/zzupload-main
upload.url=http://192.168.0.88:8080/zzupload-main
