Spring中常見(jiàn)數(shù)據(jù)源的配置參數(shù)

一共分為直接連接、連接池、jndi綁定三種

1、直接連接

<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、連接池

<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為例

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

注意每種容器的jndi寫法不同，所以java:comp/env/jdbc/TestDB為其全稱，但在配置jndi時(shí)可能會(huì)是其中一部分，如tomcat配置jdbc/TestDB

配置錯(cuò)誤會(huì)報(bào)javax.naming.NameNotFoundException: Name jdbc is not bound in this Context異常
