JavaSpring-SpringAware思维导图

在com.wisely.highlight_spring4.ch3.aware包下新建一个test.txt，内容随意，给下面的外部资源加载使用。

//1 获得Bean名称和资源加载的服务 package com.wisely.highlight_spring4.ch3.aware; @Service public class AwareService implements BeanNameAware,ResourceLoaderAware{ private String beanName; private ResourceLoader loader; @Override public void setResourceLoader(ResourceLoader resourceLoader) { //2 实现ResourceLoaderAware this.loader = resourceLoader; } @Override public void setBeanName(String name) { //3 实现BeanNameAware this.beanName = name; } public void outputResult(){ System.out.println("Bean的名称为:" + beanName); Resource resource = loader.getResource("classpath:com/wisely/highlight_spring4/ch2/aware/test.txt"); try{ System.out.println("ResourceLoader加载的文件内容为: " + IOUtils.toString(resource.getInputStream())); }catch(IOException e){ e.printStackTrace(); } } }

package com.wisely.highlight_spring4.ch3.aware; @Configuration @ComponentScan("com.wisely.highlight_spring4.ch3.aware") public class AwareConfig { }

package com.wisely.highlight_spring4.ch3.aware; 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(); } }

Bean的名称为：awareService ResourceLoader加载的文件内容为：111111
