Spring Resources接口

要获取Resource对象需要继承ResourceLoader接口

ApplicationContext继承了ResourceLoader接口，可以直接使用

esource template = ctx.getResource("some/resource/path/myTemplate.txt");

Table 6.1. Resource strings   的类型

PrefixExampleExplanation

classpath:

classpath:com/myapp/config.xml

Loaded from the classpath.

file:

file:///data/config.xml

Loaded as a URL, from the filesystem. ^[1]

http:

http://myserver/logo.png

Loaded as a URL.

(none)

/data/config.xml

Depends on the underlying ApplicationContext.

^[1]But see also Section 6.7.3, “FileSystemResource caveats”.

Resource template = ctx.getResource("classpath:some/resource/path/myTemplate.txt");

Resource template = ctx.getResource("file:///some/resource/path/myTemplate.txt");

Resource template = ctx.getResource("http://myhost.com/resource/path/myTemplate.txt");

获取ApplicationContext   对象可以继承 ApplicationContextAware      接口

Aware接口

public interface ApplicationContextAware {    void setApplicationContext(ApplicationContext applicationContext) throws BeansException;}

实现Aware接口即可在对象中使用相对应的资源，例如applicationContext.getBean("...");
