配置init-method，用来完成构造器以后执行的方法

在/cn下有一个文件（但是这个可以从其他方法中抽取出来）PersonService.java

[java] view
plaincopy

package cn;

public interface PersonService {

public abstract void save();

}

在/cn/imp文件夹下有一个java文件PersonServiceBean.java

package cn.imp;

import org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor;

import cn.PersonService;

public class PersonServiceBean implements PersonService {
/* (non-Javadoc)
* @see cn.imp.PersonService#save()
*/
public void init()
{
System.out.println("我被初始化了");
}
public void save()
{
System.out.println("我是save方法");
}
public PersonServiceBean()
{
System.out.println("我被实例化了");
}
}

建立一个测试用test

在junit.test下面SpringTest.java

[java] view
plaincopy

package junit.test;

import org.junit.Test;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.imp.PersonServiceBean;

public class SpringTest

{

@Test

public void instanceSpring()

{

ApplicationContext ctx=new ClassPathXmlApplicationContext(new String[]{"beans.xml"});

PersonServiceBean personServiceBean=(PersonServiceBean) ctx.getBean("personService");

personServiceBean.save();

}

}

在src文件夹下面有个配置文件

beans.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-2.5.xsd"> <bean id="personService" class="cn.imp.PersonServiceBean" init-method="init"></bean>

</beans>
