1、spring容器自带连接池 ~n[xtWO0

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

2、项目中创建连接池(一般利用开源项目) f 1w~!O9

3、应用服务器创建数据源,项目中通过jndi访问,以tomcat为例 Ku\Y'ub

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> F)s{P Cl
<property name="jndiName"> ]%BWIqbr
<value>java:comp/env/jdbc/TestDB</value> dxZu2&gi
</property> S,<EEtXQ
</bean> DyeQJ7p
@J5Jpt*IE
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 uq,

x~GQV^(l3
配置错误会报javax.naming.NameNotFoundException: Name jdbc is not bound in this Context异常
