Spring?Aware的目的是為了讓Bean獲得Spring容器的服務
?
//獲取容器中的bean名稱
import org.springframework.beans.factory.BeanNameAware;
//獲得資源加載器，可以獲得額外的資源
import org.springframework.context.ResourceLoaderAware;
?
package ch2.aware;
import java.io.IOException;import org.apache.commons.io.IOUtils;
//獲取容器中的bean名稱
import org.springframework.beans.factory.BeanNameAware;
//獲得資源加載器，可以獲得額外的資源
import org.springframework.context.ResourceLoaderAware;
import org.springframework.core.io.Resource;
import org.springframework.core.io.ResourceLoader;
import org.springframework.stereotype.Service;//AwareService是spring的一個組件
@Service
//實現BeanNameAware，ResourceLoaderAware資源的接口，獲得名稱和資源加載的服務
public class AwareService implements BeanNameAware,ResourceLoaderAware {private String beanName;private ResourceLoader loader;//實現ResourceLoaderAware需要重寫setResourceLoader@Overridepublic void setResourceLoader(ResourceLoader resourceLoader) {// TODO Auto-generated method stubthis.loader = resourceLoader;}//實現BeanNameAware需要重寫setBeanName@Overridepublic void setBeanName(String name) {// TODO Auto-generated method stubthis.beanName = name; }public void outputResult(){System.out.println("bean的名字為："+ beanName);Resource resource = loader.getResource("classpath:ch2/aware/test.txt");try {System.out.println("ResourceLoader加載的內容為：" + IOUtils.toString(resource.getInputStream()));} catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}
配置：
package ch2.aware;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;//聲明本類是一個配置類
@Configuration
//自動加載ch2.aware包下面的內容
@ComponentScan("ch2.aware")
public class AwareConfig {}
運行：
package ch2.aware;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;public class Main {public static void main(String[] args){AnnotationConfigApplicationContext context= new AnnotationConfigApplicationContext(AwareConfig.class);AwareService awareService = context.getBean(AwareService.class);awareService.outputResult();context.close();}}
