- org.springframework.web.servlet.handler.HandlerMappingIntrospector

所有已实现的接口:
Aware, InitializingBean, ApplicationContextAware, CorsConfigurationSource
```
public class HandlerMappingIntrospector
extends Object
implements CorsConfigurationSource, ApplicationContextAware, InitializingBean
```
Helper class to get information from the HandlerMapping that would serve a specific request.
Provides the following methods:
- getMatchableHandlerMapping(javax.servlet.http.HttpServletRequest) — obtain a HandlerMapping to check request-matching criteria against.
- getCorsConfiguration(javax.servlet.http.HttpServletRequest) — obtain the CORS configuration for the request.
从以下版本开始:

所有方法实例方法具体方法
修饰符和类型	方法	说明
`void`	`afterPropertiesSet()`	Invoked by the containing `BeanFactory` after it has set all bean properties and satisfied `BeanFactoryAware`, `ApplicationContextAware` etc.
`CorsConfiguration`	`getCorsConfiguration(HttpServletRequest request)`	Return a `CorsConfiguration` based on the incoming request.
`List<HandlerMapping>`	`getHandlerMappings()`	Return the configured HandlerMapping's.
`MatchableHandlerMapping`	`getMatchableHandlerMapping(HttpServletRequest request)`	Find the `HandlerMapping` that would handle the given request and return it as a `MatchableHandlerMapping` that can be used to test request-matching criteria.
`void`	`setApplicationContext(ApplicationContext applicationContext)`	Set the ApplicationContext that this object runs in.

```
public HandlerMappingIntrospector()

```
@Deprecated
public HandlerMappingIntrospector(ApplicationContext context)
```
    已过时。
    as of 4.3.12, in favor of setApplicationContext(org.springframework.context.ApplicationContext)
    Constructor that detects the configured HandlerMappings in the given ApplicationContext or falls back on "DispatcherServlet.properties" like the DispatcherServlet.
- 方法详细资料
  - getHandlerMappings
```
public List<HandlerMapping> getHandlerMappings()
```
    Return the configured HandlerMapping's.
  - setApplicationContext
```
public void setApplicationContext(ApplicationContext applicationContext)
```
    从接口复制的说明: ApplicationContextAware
    Set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.
    Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesSet() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(org.springframework.core.io.ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(org.springframework.context.ApplicationEventPublisher) and MessageSourceAware, if applicable.
    指定者:
    setApplicationContext 在接口中 ApplicationContextAware
    参数:
    applicationContext - the ApplicationContext object to be used by this object
    另请参阅:
    BeanInitializationException
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    从接口复制的说明: InitializingBean
    Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.
    This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
    指定者:
    afterPropertiesSet 在接口中 InitializingBean
  - getMatchableHandlerMapping
```
@Nullable
public MatchableHandlerMapping getMatchableHandlerMapping(HttpServletRequest request)
                                                   throws Exception
```
    Find the HandlerMapping that would handle the given request and return it as a MatchableHandlerMapping that can be used to test request-matching criteria.
    If the matching HandlerMapping is not an instance of MatchableHandlerMapping, an IllegalStateException is raised.
    参数:
    request - the current request
    返回:
    the resolved matcher, or null
    抛出:
    Exception - if any of the HandlerMapping's raise an exception
  - getCorsConfiguration
```
@Nullable
public CorsConfiguration getCorsConfiguration(HttpServletRequest request)
```
    从接口复制的说明: CorsConfigurationSource
    Return a CorsConfiguration based on the incoming request.
    指定者:
    getCorsConfiguration 在接口中 CorsConfigurationSource
    返回:
    the associated CorsConfiguration, or null if none
