测试类:
package com.mangocity.spring.test;

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

public class SpringTest {
	public static void main(String[] args) {
           ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml");
           Spring s = (Spring) context.getBean("salService");
           s.argsTest("测试");
	}
}

输出结果:
beforePrintContent...测试
测试
afterPrintContent...
