- org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry

```
public class ResourceHandlerRegistry
extends Object
```
Stores registrations of resource handlers for serving static resources such as images, css files and others through Spring MVC including setting cache headers optimized for efficient loading in a web browser. Resources can be served out of locations under web application root, from the classpath, and others.
To create a resource handler, use addResourceHandler(String...) providing the URL path patterns for which the handler should be invoked to serve static resources (e.g. "/resources/**").
Then use additional methods on the returned ResourceHandlerRegistration to add one or more locations from which to serve static content from (e.g. {"/", "classpath:/META-INF/public-web-resources/"}) or to specify a cache period for served resources.

```
public ResourceHandlerRegistration addResourceHandler(String... pathPatterns)
```
    Add a resource handler for serving static resources based on the specified URL path patterns. The handler will be invoked for every incoming request that matches to one of the specified path patterns.
    Patterns like "/static/**" or "/css/{filename:\\w+\\.css}" are allowed. See AntPathMatcher for more details on the syntax.
    返回:
    a ResourceHandlerRegistration to use to further configure the registered resource handler
  - hasMappingForPattern
```
public boolean hasMappingForPattern(String pathPattern)
```
    Whether a resource handler has already been registered for the given path pattern.
  - setOrder
```
public ResourceHandlerRegistry setOrder(int order)
```
    Specify the order to use for resource handling relative to other HandlerMappings configured in the Spring MVC application context.
    The default value used is Integer.MAX_VALUE-1.
  - getHandlerMapping
