ibatis
spring配置ibatis的jdbc方式和proxool連接池方式，以sqlserver2005為例，驅動為sqljdbc.jar
jdbc.properties中內容如下
jdbc.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
jdbc.url=jdbc\:sqlserver\://localhost\:1433; DatabaseName\=IBATIS
jdbc.username=sa
jdbc.password=123456
1 直接用jdbc方式（這種方式適合開發階段，發布的程序強烈要求用連接池），代碼如下，這個都知道，沒什么可說的

SqlMapConfig.xml內容如下：
<!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
"http://www.ibatis.com/dtd/sql-map-config-2.dtd">
<sqlMapConfig>
<sqlMap resource="com/mydomain/data/Account.xml"/>
</sqlMapConfig>
2 用proxool連接池方式，只有datasource發生變化，其他的無變動
需要加入proxool.jar
<bean id="dataSource" class="org.logicalcobwebs.proxool.ProxoolDataSource" destroy-method="close">
<property name="alias" value="test"></property>
<property name="delegateProperties">
<value>user=${jdbc.username},password=${jdbc.password}</value>
</property>
<property name="user" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="driver" value="${jdbc.driverClassName}"/>
<property name="driverUrl" value="${jdbc.url}"/>
<property name="houseKeepingTestSql" value="select CURRENT_DATE"></property>
<!--此處繼續增加proxool屬性，詳細見proxool文檔-->
</bean>
此處說明一下：屬性中的user和password不起任何作用，需要用delegateProperties方式寫一下，否則會報錯誤，如下
org.springframework.transaction.CannotCreateTransactionException: Could not open JDBC Connection for transaction; nested exception is com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user ''. The user is not associated with a trusted SQL Server connection.
但是user和password還不能被去掉。
除了上面的用delegateProperties之外，還可以將用戶名和密碼直接寫在url后面。
proxool屬性的說明，在這里寫的比較詳細

3 c3p0方式
需要加入c3p0.jar
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
<property name="driverClass">
<value>${jdbc.driverClassName}</value>
</property>
<property name="jdbcUrl">
<value>${jdbc.url}</value>
</property>
<property name="user">
<value>${jdbc.username}</value>
</property>
<property name="password">
<value>${jdbc.password}</value>
</property>
<!--此處繼續增加c3p0
屬性-->
</bean>
