Method Detail

lookupHandler

protected Object lookupHandler(String urlPath,
                               javax.servlet.http.HttpServletRequest request)
                        throws Exception

Look up a handler instance for the given URL path.

Supports direct matches, e.g. a registered "/test" matches "/test", and various Ant-style pattern matches, e.g. a registered "/t*" matches both "/test" and "/team". For details, see the AntPathMatcher class.

Looks for the most exact pattern, where most exact is defined as the longest path pattern.

Overrides:

lookupHandler in class org.springframework.web.servlet.handler.AbstractUrlHandlerMapping

Parameters:

urlPath - URL the bean is mapped to

request - current HTTP request (to expose the path within the mapping to)

Returns:

the associated handler instance, or null if not found

Throws:

Exception - in case of an error

registerController

public void registerController(org.springframework.web.servlet.mvc.Controller controller,
                               List<String> urlPatterns)

Parameters:

controller - the controller

urlPatterns - the url patterns of the controller

registerDefaultHandler

protected void registerDefaultHandler(String urlPath,
                                      org.springframework.web.servlet.mvc.Controller handler)
                               throws org.springframework.beans.BeansException,
                                      IllegalStateException

Register the specified handler for the given URL path.

Parameters:

urlPath - the URL the bean should be mapped to

handler - the handler instance or handler bean name String (a bean name will automatically be resolved into the corresponding handler bean)

Throws:

org.springframework.beans.BeansException - if the handler couldn't be registered

IllegalStateException - if there is a conflicting handler registered

reloadHandlerMap

public void reloadHandlerMap()

reloades the merged url map

unregisterController

public void unregisterController(org.springframework.web.servlet.mvc.Controller controller)

Unregister all handlers specified in the URL map for the corresponding plugin.

Parameters:

controller - the controller
