- - org.springframework.web.servlet.resource.CssLinkResourceTransformer

所有已实现的接口:
ResourceTransformer
```
public class CssLinkResourceTransformer
extends ResourceTransformerSupport
```
A ResourceTransformer implementation that modifies links in a CSS file to match the public URL paths that should be exposed to clients (e.g. with an MD5 content-based hash inserted in the URL).
The implementation looks for links in CSS @import statements and also inside CSS url() functions. All links are then passed through the ResourceResolverChain and resolved relative to the location of the containing CSS file. If successfully resolved, the link is modified, otherwise the original link is preserved.
