CompositeConfiguration的用法

public class Mytest {

    private static ApplicationContext applicationContext;

    public static void main(String[] args) throws Exception {
        
        //获取spring上下文
        applicationContext = new ClassPathXmlApplicationContext("applicationContext-config.xml");
        
        CompositeConfiguration configuration = new CompositeConfiguration();
        XMLConfiguration config = (XMLConfiguration) applicationContext.getBean("xmlConfiguration");
        configuration.addConfiguration(config);
        
        String value = configuration.getString("test.url");
        System.out.println(value);//运行结果http://www.baidu.com
    }
}

　　

applicationContext-config.xml

<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="xmlConfiguration" class="org.apache.commons.configuration.XMLConfiguration">
          <constructor-arg index="0" type="java.net.URL" value="classpath:local-app.xml"/>
   </bean>
</beans>

　　

local-app.xml

<?xml version="1.0" encoding="UTF-8"?>
<appconfig>
    <test>
        <url>http://www.baidu.com</url>
    </test>
</appconfig>
