Spring中常见数据源的配置参数
一共分为直接连接、连接池、jndi绑定三种
1、直接连接
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://127.0.0.1:3306/test</value>
</property>
<property name="username">
<value>admin</value>
</property>
<property name="password">
<value/>
</property>
</bean>
2、连接池
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>jdbc:mysql://127.0.0.1:3306/test</value>
</property>
<property name="username">
<value>admin</value>
</property>
<property name="password">
<value/>
</property>
</bean>
3 jndi,以tomcat为例
<bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName">
<value>java:comp/env/jdbc/TestDB</value>
</property>
</bean>
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
配置错误会报javax.naming.NameNotFoundException: Name jdbc is not bound in this Context异常
