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 MP$9W)

1、spring容器自带连接池 ayrCLv

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> $HP<C>^Z8
<property name="driverClassName"> VRD:PVz
<value>com.mysql.jdbc.Driver</value> ]La~Bh6;m
</property> fzjAP7 y
<property name="url"> lky5%H

2、项目中创建连接池(一般利用开源项目) 0F9p'_C

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> si#1sdR
<property name="driverClassName"> raJv$P

3、应用服务器创建数据源,项目中通过jndi访问,以tomcat为例 #83pitcc
q!AcMd\
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> p mUG`8SY
<property name="jndiName"> vbEO pYCS
<value>java:comp/env/jdbc/TestDB</value> T!Nv
</property> jJyS^*.X
</bean> )8%m|v#W
nd~O*-uYg
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 S#*aB2ZS

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