Spring 学习——Resources接口

Resources

• 针对资源文件的统一接口
• Resources
  • UrlResource:URL对应的资源，只需要一个url即可构建
  • ClassPathResource:获取类路径下的资源文件
  • FileSystemResource:获取文件系统里面的资源
  • ServletContextResource:ServletContext封装的资源，用于访问ServletContext环境下的资源
  • InputStreamResource:针对于输入流封装的资源
  • ByteArrayResource:针对于字节数组封装的资源
• ResourceLoader
  • All application contexts implements the ResourceLoader interface,and therefore all application contexts may be used to obtain Resources Instances

    public interface Resource{
         Resource getResource(String location);           
    }
    
    Example
    Resource resource1=ctx.getResource("some/location/myTemplate.txt");
    Resource resource2=ctx.getResource("classpath:some/location/myTemplate.txt");
    Resource resource3=ctx.getResource("file:/some/location/myTemplate.txt");
