```
public RequestMappingHandlerMapping()
```
- Method Detail
  - setPathPrefixes
```
public void setPathPrefixes(Map<String,Predicate<Class<?>>> prefixes)
```
    Configure path prefixes to apply to controller methods.
    Prefixes are used to enrich the mappings of every @RequestMapping method whose controller type is matched by a corresponding Predicate in the map. The prefix for the first matching predicate is used, assuming the input map has predictable order.
    Consider using HandlerTypePredicate to group controllers.
    Parameters:
    prefixes - a map with path prefixes as key
    Since:
    5.1
    See Also:
    HandlerTypePredicate
  - getPathPrefixes
```
public Map<String,Predicate<Class<?>>> getPathPrefixes()
```
    The configured path prefixes as a read-only, possibly empty map.
    Since:
    5.1
  - setContentTypeResolver
```
public void setContentTypeResolver(RequestedContentTypeResolver contentTypeResolver)
```
    Set the RequestedContentTypeResolver to use to determine requested media types. If not set, the default constructor is used.
  - getContentTypeResolver
```
public RequestedContentTypeResolver getContentTypeResolver()
```
    Return the configured RequestedContentTypeResolver.
  - setEmbeddedValueResolver
```
public void setEmbeddedValueResolver(StringValueResolver resolver)
```
    Description copied from interface: EmbeddedValueResolverAware
    Set the StringValueResolver to use for resolving embedded definition values.
    Specified by:
    setEmbeddedValueResolver in interface EmbeddedValueResolverAware
  - afterPropertiesSet
```
public void afterPropertiesSet()
```
    Description copied from class: AbstractHandlerMethodMapping
    Detects handler methods at initialization.
    Specified by:
    afterPropertiesSet in interface InitializingBean
    Overrides:
    afterPropertiesSet in class AbstractHandlerMethodMapping<RequestMappingInfo>
  - isHandler
```
protected boolean isHandler(Class<?> beanType)
```
    Whether the given type is a handler with handler methods. Expects a handler to have a type-level @Controller annotation.
    Specified by:
    isHandler in class AbstractHandlerMethodMapping<RequestMappingInfo>
    Parameters:
    beanType - the type of the bean being checked
    Returns:
    "true" if this a handler type, "false" otherwise.
  - getMappingForMethod
```
@Nullable
protected RequestMappingInfo getMappingForMethod(Method method,
                                                 Class<?> handlerType)
```
    Uses method and type-level @RequestMapping annotations to create the RequestMappingInfo.
    Specified by:
    getMappingForMethod in class AbstractHandlerMethodMapping<RequestMappingInfo>
    Parameters:
    method - the method to provide a mapping for
    handlerType - the handler type, possibly a sub-type of the method's declaring class
    Returns:
    the created RequestMappingInfo, or null if the method does not have a @RequestMapping annotation.
    See Also:
    getCustomMethodCondition(Method), getCustomTypeCondition(Class)
  - getCustomTypeCondition
```
@Nullable
protected RequestCondition<?> getCustomTypeCondition(Class<?> handlerType)
```
    Provide a custom type-level request condition. The custom RequestCondition can be of any type so long as the same condition type is returned from all calls to this method in order to ensure custom request conditions can be combined and compared.
    Consider extending AbstractRequestCondition for custom condition types and using CompositeRequestCondition to provide multiple custom conditions.
    Parameters:
    handlerType - the handler type for which to create the condition
    Returns:
    the condition, or null
  - getCustomMethodCondition
```
@Nullable
protected RequestCondition<?> getCustomMethodCondition(Method method)
```
    Provide a custom method-level request condition. The custom RequestCondition can be of any type so long as the same condition type is returned from all calls to this method in order to ensure custom request conditions can be combined and compared.
    Consider extending AbstractRequestCondition for custom condition types and using CompositeRequestCondition to provide multiple custom conditions.
    Parameters:
    method - the handler method for which to create the condition
    Returns:
    the condition, or null
  - createRequestMappingInfo
```
protected RequestMappingInfo createRequestMappingInfo(RequestMapping requestMapping,
                                                      @Nullable

```
protected String[] resolveEmbeddedValuesInPatterns(String[] patterns)
```
    Resolve placeholder values in the given array of patterns.
    Returns:
    a new array with updated patterns
