Spring MVC 三种参数注入

1）参数注入第一种方法

<!-- xml服务 -->
<bean id="xmlWriteService" class="com.proxy.util.XmlWriteService"></bean>

private XmlWriteService xmlWriteService;

@Override
public void init() throws ServletException {
	super.init();
	xmlWriteService = SpringUtil.getBean("xmlWriteService");
}

2）参数注入第二种方法

public class TestHelloBean extends TestCase {   
    /*  
     * BeanFactory负责读取Bean的定义文件;管理对象的加载。生成。维护Bean对象与Bean对象之间的依赖关系  
     * 但只适合简单的应用程序  
     */  
    public void testHelloWord() {   
        Resource rs = new ClassPathResource("hellobean-config.xml");   
        BeanFactory factory = new XmlBeanFactory(rs);   
        HelloBean hello = (HelloBean) factory.getBean("helloBean");   
        HelloBean hello2 = (HelloBean) factory.getBean("helloBean2");   
           
        System.out.println(hello.getHelloWord()+"  "+hello.getName());   
           
        System.out.println(hello2.getHelloWord()+"  "+(Date)hello2.getDate());   
    }   
} 

3）参数注入第三种方法

<!-- 上传图片到代理 -->
	<bean id="uploadImgToProxyService" class="com.anxin.sskmis.util.UploadImgToProxyService">
		<property name="uploadImgUrl"
			value="http://192.168.5.244/coupon-proxy-website/couponServlet.coupon" />
		<property name="md5Key" value="310109780581677" />
		<property name="service" value="commonImgUpload" />
	</bean>
	
	<!-- 参数注入 -->
	<bean id="adsServiceImpl" class="com.anxin.sskmis.biz.ads.impl.AdsServiceImpl">
		<property name="uploadImgToProxyService" ref="uploadImgToProxyService"/>
	</bean>
