spring 通过jndi配置一个或者多个数据源

META-INF目录下建一个context.xml文件

 <?xml version="1.0" encoding="UTF-8"?>
 <Context>
    <Resource name="jndiString_1" auth="Container"
             type="javax.sql.DataSource"
            maxActive="100"
            maxIdle="30"
            maxWait="10000"
            username="username"
            password="passwd"
            driverClassName="oracle.jdbc.OracleDriver"
            url="jdbc:oracle:thin:@192.168.1.88:1521:databaseName1"/>

    <Resource name="jndiString_2" auth="Container"
             type="javax.sql.DataSource"
            maxActive="100"
            maxIdle="30"
            maxWait="10000"
            username="username"
            password="passwd"
            driverClassName="oracle.jdbc.OracleDriver"
            url="jdbc:oracle:thin:@192.168.1.88:1521:databaseName2"/>


 </Context>

  上述jndiString 只是一个存在于容器中的标识字符,需要在下面spring配置中引用.


spring配置文件spring-core.xml中

    <bean id="jndiString_1" class="java.lang.String">
        <constructor-arg>
            <value>java:comp/env/jndiString_1</value>
        </constructor-arg>
    </bean>

    <bean id="jndiString_2" class="java.lang.String">
        <constructor-arg>
            <value>java:comp/env/jndiString_2</value>
        </constructor-arg>
    </bean>



    <bean id="dataSource1"
          class="org.springframework.jndi.JndiObjectFactoryBean"   
                         singleton="true">
        <property name="jndiName">
            <ref local="jndiString_1"/>
        </property>
    </bean> 

    <bean id="dataSource2"
          class="org.springframework.jndi.JndiObjectFactoryBean"   
                         singleton="true">
        <property name="jndiName">
            <ref local="jndiString_2"/>
        </property>
    </bean> 

   ......

以上程序启动需要容器支持,如果要进行单元测试 这样配置是跑不起来滴.
单元测试的配置 就直接在spring 里面配一下吧!

    <bean id="dataSource"    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName">
            <value>oracle.jdbc.OracleDriver</value>
        </property>
        <property name="url">
            <value>jdbc:oracle:thin:@192.168.1.88:1521:databaseName</value>
        </property>
        <property name="username">
            <value>username</value>
        </property>
        <property name="password">
            <value>passwd</value>
        </property>
    </bean>

OK!
