java applicationContext.getResource中的资源路径

java applicationContext.getResource中的资源路径

1、类路径-资源通配

ConfigurableApplicationContext applicationContext = SpringApplication.run(Application.class, args);
		// 类路径下-资源通配符
		Resource[] resources = applicationContext.getResources("classpath:com/asia/tip/controller/Sen*");
		for (Resource resource : resources) 
			System.out.println(resource.getFilename());
			System.out.println(resource.contentLength());
		

补充说明：类路径是以编译后的路径为准，向resources下的配置文件，编译后的位置如下：

2、类路径含jar包内资源-资源通配

ConfigurableApplicationContext applicationContext = SpringApplication.run(Application.class, args);
		// 类路径包含jar内资源-资源通配符
		Resource[] resources = applicationContext.getResources("classpath*:META-INF/spring.factories");
		for (Resource resource : resources) 
			System.out.println(resource.getFilename());
			System.out.println(resource.contentLength());
			
		

3、磁盘路径-资源通配

ConfigurableApplicationContext applicationContext = SpringApplication.run(Application.class, args);
		// 磁盘径下-资源通配符
		Resource[] resources = applicationContext.getResources("file:D:/log4j.log");
		for (Resource resource : resources) 
			System.out.println(resource.getFilename());
			System.out.println(resource.contentLength());
