1. 在程序中提供需要依赖Spring为其注入属性的属性名和类型
package com.hao947.ioc; public class UserService { private String name; private String year; public void setName(String name) { this.name = name; } public void setYear(String year) { this.year = year; } public void show() { System.out.println("show...." + name + "," + year); } }
2. 提供该属性的setter方法(标准封装的setter方法)
3. spring中初始化该资源Bean时为其提供资源的值
<?xml version="1.0" encoding="UTF-8"?> <!-- 整个Spring文件根元素就是beans --> <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-3.1.xsd"> <!-- 此处及用Bean元素来定义Spring能创建的对象 --> <bean id="userService" class="com.hao947.ioc.UserService"> <!-- 为该Bean提供资源 --> <property name="name" value="hao947"></property> <property name="year" value="2014"></property> </bean> </beans>
4.调试
public class IoCApp { @Test public void hao947() { // 获取Bean需要使用Spring的工厂类 ApplicationContext act = new ClassPathXmlApplicationContext( "applicatioContext.xml"); // 获取Bean UserService us = (UserService) act.getBean("userService"); // 执行操作 us.show(); System.out.println(us); } }
