本文介绍如何在Spring框架中加载多个配置文件，并通过示例展示了如何定义和使用这些配置文件来设置数据库连接和iBatis层。

Spring 加载多个applicationContext

// java 类 MyDataSource 是 .DAO 类

public static void util(){

  ClassPathXmlApplicationContext resource = new ClassPathXmlApplicationContext(new String[]{"applicationContext-database.xml","applicationContext-ibatis.xml","applicationContext-beans.xml"});
  BeanFactory factory = resource;

  MyDataSource myData=(MyDataSource)factory.getBean("myDataSource");

   }

// 三个bean文件配置

applicationContext-database.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "spring-beans.dtd">
<beans>

   <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName"><value>oracle.jdbc.driver.OracleDriver</value></property>
        <property name="url"><value>jdbc:oracle:thin:@172.16.3.67:1521:orcl</value></property>
        <property name="username"><value>zfoa</value></property>
        <property name="password"><value>zfoa</value></property>
    </bean>
</beans>

applicationContext-ibatis.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "spring-beans.dtd">
<beans>


<bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
    <property name="configLocation" value="classpath:sql-map-config.xml"/>
    <property name="dataSource"ref="dataSource"/>
</bean>
</beans>

applicationContext-beans.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "spring-beans.dtd">
