	<!-- xmlns:context命名空间 导入非spring的配置文件的内容 -->
	<context:property-placeholder location="classpath:test.properties" />
	
	<util:list id="list">
		<value>${user}</value>
		<value>${pass}</value>
		<value>借助list测试下导入 不写额外的bean了</value>

类路径下的properties文件内容

user=root
pass=123456

测试main

package top.demo.test.spring2;

import java.util.Arrays;
import java.util.List;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Main {
	
	
	public static void main(String argv[]) {
		
		ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext2.xml");
		List list=(List) ctx.getBean("list");
		System.out.println(list.toString());

		
	}
	
}
