1、同时指定多个配置文件

 ApplicationContext context = new ClassPathXmlApplicationContext("application.xml", "dao.xml", "service.xml");

2、配置文件拆分

如果配置文件内容太多，可以拆分成多个配置文件，如：将一个工程的配置文件拆分为dao.xml，service.xml，然后通过application.xml 引入

application.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <import resource="dao.xml"></import>
    <import resource="service.xml"></import>
</beans>

dao.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="daoBean" class="spring.example.DaoBean">
    </bean>
</beans>

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="serviceBean" class="spring.example.ServiceBean">
    </bean>
</beans>

使用的时候，只需要引入application.xml文件即可：

 ApplicationContext context = new ClassPathXmlApplicationContext("application.xml");
