您好!感谢您的提问。对于Spring MVC中配置MySQL和Oracle双数据源,请您在applicationContext.xml文件中进行如下配置:
1. 配置MySQL数据源:
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/your_db_name" />
<property name="username" value="your_username" />
<property name="password" value="your_password" />
</bean>
2. 配置Oracle数据源:
<bean id="oracleDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.driver.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@localhost:1521:your_db_name" />
<property name="username" value="your_username" />
<property name="password" value="your_password" />
</bean>
3. 配置双数据源:
<bean id="dataSourceA" parent="dataSource">
<property name="url" value="jdbc:mysql://localhost:3306/db_name_A" />
</bean>
<bean id="dataSourceB" parent="dataSource">
<property name="url" value="jdbc:oracle:thin:@localhost:1521/db_name_B" />
</bean>
4. 配置事务管理器:
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSourceA" />
</bean>
5. 配置DAO:
<bean id="daoA" class="com.example.DaoA">
<property name="dataSource" ref="dataSourceA" />
</bean>
<bean id="daoB" class="com.example.DaoB">
<property name="dataSource" ref="dataSourceB" />
</bean>
6. 配置Service:
<bean id="serviceA" class="com.example.ServiceA">
<property name="transactionManager" ref="transactionManager" />
<property name="daoA" ref="daoA" />
</bean>
<bean id="serviceB" class="com.example.ServiceB">
<property name="transactionManager" ref="transactionManager" />
<property name="daoB" ref="daoB" />
</bean>
注意:上述配置仅供参考,具体配置根据您的实际情况进行调整。
