1、spring容器自带连接池 >t_h/:JZ)
" 2~L
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> _70Z1_;
<property name="driverClassName"> @V&c=8)8
<value>com.mysql.jdbc.Driver</value> FS)"MDs
</property> *

2、项目中创建连接池(一般利用开源项目) eaAGlEW6J
[{$%9lm
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> Bd]k]v+
<property name="driverClassName"> /%mT2
<value>com.mysql.jdbc.Driver</value> ;1HzY\d%<
</property> ]rG/?1'^i

3、应用服务器创建数据源,项目中通过jndi访问,以tomcat为例 z2>LjM)
#
[!De|,u(^
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> 57~y 7/ 0
<property name="jndiName"> ZTibF'\5N
<value>java:comp/env/jdbc/TestDB</value> D4b-Y[/"
</property> VV{>Kq+&,v
</bean> RA!q)/+
/5<= m:
注意每种容器的jndi写法不同,所以java:comp/env/jdbc/TestDB为其全称,但在配置jndi时可能会是其中一部分,如tomcat配置jdbc/TestDB 8t3m$<7
<.mH-Y5i
配置错误会报javax.naming.NameNotFoundException: Name jdbc is not bound in this Context异常
