关键代码

<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
		<property name="jndiName">
			<value>java:comp/env/jdbc/ghdb</value>
		</property>
		<property name="resourceRef">
			<value>true</value>
		</property>
	</bean>

全局jndi配置

Tomcat7\conf\context.xml下新增如下代码

<Resource auth="Container" driverClassName="com.mysql.jdbc.Driver"
		logAbandoned="true" maxActive="20" maxIdle="10" maxWait="1000" name="jdbc/ghdb"
		password="root" removeAbandoned="true" removeAbandonedTimeout="60"
		type="javax.sql.DataSource"
		url="jdbc:mysql://127.0.0.1:3306/kdddb?generateSimpleParameterMetadata=true&characterEncoding=utf8&autoReconnect=true"
		useUnicode="true"
		username="root" />

注意

name="jdbc/ghdb"

和

<property name="jndiName">
			<value>java:comp/env/jdbc/ghdb</value>
		</property>
