一个测试Bean:
package util; public class TestBean { private Integer co;public Integer getCo() { return co;}public void setCo(Integer co) { this.co = co;}}
一个测试属性文件config.properties
prop1=propValue1prop2=propValue2

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