Constructor Detail

AbstractControllerUrlHandlerMapping

public AbstractControllerUrlHandlerMapping()

Method Detail

setIncludeAnnotatedControllers

public void setIncludeAnnotatedControllers(boolean includeAnnotatedControllers)

Set whether to activate or deactivate detection of annotated controllers.

setExcludedPackages

public void setExcludedPackages(String[] excludedPackages)

Specify Java packages that should be excluded from this mapping. Any classes in such a package (or any of its subpackages) will be ignored by this HandlerMapping.

Default is to exclude the entire "org.springframework.web.servlet.mvc" package, including its subpackages, since none of Spring's out-of-the-box Controller implementations is a reasonable candidate for this mapping strategy. Such controllers are typically handled by a separate HandlerMapping, e.g. a BeanNameUrlHandlerMapping, alongside this ControllerClassNameHandlerMapping for application controllers.

setExcludedClasses

public void setExcludedClasses(Class[] excludedClasses)

Specify controller classes that should be excluded from this mapping. Any such classes will simply be ignored by this HandlerMapping.

determineUrlsForHandler

protected String[] determineUrlsForHandler(String beanName)

This implementation delegates to buildUrlsForHandler(java.lang.String, java.lang.Class), provided that isEligibleForMapping(java.lang.String, java.lang.Class) returns true.

Specified by:

determineUrlsForHandler in class AbstractDetectingUrlHandlerMapping

Parameters:

beanName - the name of the candidate bean

Returns:

the URLs determined for the bean, or null or an empty array if none

isEligibleForMapping

protected boolean isEligibleForMapping(String beanName,
                                       Class beanClass)

Determine whether the specified controller is excluded from this mapping.

Parameters:

beanName - the name of the controller bean

beanClass - the concrete class of the controller bean

Returns:

whether the specified class is excluded

See Also:

setExcludedPackages(java.lang.String[]), setExcludedClasses(java.lang.Class[])

isControllerType

protected boolean isControllerType(Class beanClass)

Determine whether the given bean class indicates a controller type that is supported by this mapping strategy.

Parameters:

beanClass - the class to introspect

isMultiActionControllerType

protected boolean isMultiActionControllerType(Class beanClass)

Determine whether the given bean class indicates a controller type that dispatches to multiple action methods.

Parameters:

beanClass - the class to introspect

buildUrlsForHandler

protected abstract String[] buildUrlsForHandler(String beanName,
                                                Class beanClass)

Abstract template method to be implemented by subclasses.

Parameters:

beanName - the name of the bean

beanClass - the type of the bean

Returns:

the URLs determined for the bean
