1、spring容器自带连接池 28C/^4
RlyF#X#7{
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> ZwB<
{?
<property name="driverClassName"> D3$PvX[f
<value>com.mysql.jdbc.Driver</value>
@D^y<7(
</property> @bOhnd#W
<property name="url"> EA|*|o4)
<value>jdbc:mysql://127.0.0.1:3306/test</value> &Vg+n0
</property> iUFS1SN \

<property name="password"> RmY5/IYR|:

</property> 'U.)f@L#w
</bean> O;9u1,%w

2、项目中创建连接池(一般利用开源项目) 21bvSK

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> f)l:^/WP+
<property name="driverClassName"> 8s-y+M@.
<value>com.mysql.jdbc.Driver</value> msM

<property name="password"> D)U

</property> UBzX%:A
</bean> Z,)4(#b =
jOa .h
3、应用服务器创建数据源,项目中通过jndi访问,以tomcat为例 ^=.R#zrc
D+P(
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> F{0Z
<property name="jndiName"> BaZ$p O^
<value>java:comp/env/jdbc/TestDB</value> x^Q:U1
</property> aY}:9qBice
</bean> )=;GQ*<8Zs
Wf/r@/q
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 f_Ma~'3

配置错误会报javax.naming.NameNotFoundException: Name jdbc is not bound in this Context异常
