spring配置ibatis的jdbc方式和proxool、c3p0连接池方式

spring配置ibatis的jdbc方式和proxool连接池方式，以sqlserver2005为例，驱动为sqljdbc.jar
jdbc.properties中内容如下

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（这种方式适合开发阶段，发布的程序强烈要求用连接池），代码如下，这个都知道，没什么可说的

 </ context:component-scan >
 < context:property-placeholder location ="classpath:jdbc.properties" />
 < bean id ="dataSource"

 </ bean >

 < bean id ="sqlMapClient" class ="org.springframework.orm.ibatis.SqlMapClientFactoryBean" >
 < property name ="configLocation" value ="classpath:com/mydomain/data/SqlMapConfig.xml" />
 < property name ="dataSource" ref ="dataSource" />
 </ bean >
 
 < bean id ="txManager" class ="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
 < property name ="dataSource" ref ="dataSource" />
 </ bean >
 < aop:config >

 < tx:method name ="add*" propagation ="REQUIRED" isolation ="REPEATABLE_READ" />
 < tx:method name ="delete*" propagation ="REQUIRED" isolation ="REPEATABLE_READ" />
 </ tx:attributes >
 </ tx:advice >
</ beans >

SqlMapConfig.xml内容如下：

<! 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连接池方式，只有datasource发生变化，其他的无变动
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 >
 <!--

此处继续增加proxool属性，详细见proxool文档-->
</ bean >

此处说明一下：属性中的user和password不起任何作用，需要用delegateProperties方式写一下，否则会报错误，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还不能被去掉。

除了上面的用delegateProperties之外，还可以将用户名和密码直接写在url后面。

proxool属性的说明，在这里写的比较详细

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 >
 <!--

此处继续增加c3p0 属性-->
</ bean >
