共分spring容器自带连接池、项目中创建连接池、服务器创建连接池三种 _Jy7` 4B.

1、spring容器自带连接池 ^M{,{bG
h PL]B_<
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> e2f+Fv
9
<property name="driverClassName"> q3AqU?f
<value>com.mysql.jdbc.Driver</value> Aa=:AkrH
</property> [Ur\^wS
<property name="url"> s$).Z(6

2、项目中创建连接池(一般利用开源项目) wqhktgG

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> "|h%Uy?XY
<property name="driverClassName"> ^cm]
[9
<value>com.mysql.jdbc.Driver</value> TG%B:^Yz!
</property> x2rAB5r6
<property name="url"> L.Qz29\
<value>jdbc:mysql://127.0.0.1:3306/test</value> n:,mo} ?X

<property name="password"> 3''Sx8p

3、应用服务器创建数据源,项目中通过jndi访问,以tomcat为例 BDTL5N
Mf1(4F
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> x@t?7 o\&
<property name="jndiName"> _y@].G
<value>java:comp/env/jdbc/TestDB</value> 1z?}'&:
</property> )th[fUC(
</bean> +!/ATR%Uci
qhEv6Yxfw6
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 Nc;O)K!FH

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