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

All Implemented Interfaces:
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.
Since:
4.3.1

Constructor	Description
`HandlerMappingIntrospector()`	Constructor for use with `ApplicationContextAware`.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`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()
```
    Constructor for use with ApplicationContextAware.
  - HandlerMappingIntrospector
```
@Deprecated
public HandlerMappingIntrospector(ApplicationContext context)
```
    Deprecated.
    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.
- Method Detail
  - getHandlerMappings
```
public List<HandlerMapping> getHandlerMappings()
```
    Return the configured HandlerMapping's.
  - setApplicationContext
```
public void setApplicationContext(ApplicationContext applicationContext)
```
    Description copied from interface: 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.
    Specified by:
    setApplicationContext in interface ApplicationContextAware
    Parameters:
    applicationContext - the ApplicationContext object to be used by this object

    BeanInitializationException
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    Description copied from interface: 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.
    Specified by:
    afterPropertiesSet in interface InitializingBean
  - getMatchableHandlerMapping
```
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.
    Parameters:
    request - the current request
    Returns:
    the resolved matcher, or null
    Throws:
    Exception - if any of the HandlerMapping's raise an exception
  - getCorsConfiguration
```
public CorsConfiguration getCorsConfiguration(HttpServletRequest request)
```
    Description copied from interface: CorsConfigurationSource
    Return a CorsConfiguration based on the incoming request.
    Specified by:
    getCorsConfiguration in interface CorsConfigurationSource
    Returns:
    the associated CorsConfiguration, or null if none
