Field Summary

static String

PATH_VAR_PATTERN A pattern describing a RESTful url variable

Constructor Summary

RequestUtils()

Method Summary

static Annotation	findHandlerAnnotation(Class handlerClass, Class annotationClass) Find an annotation on the possibly proxied handler.
static String	findMatchingRestPath(String[] candidateViewNames, String[] controllerPaths, javax.servlet.http.HttpServletRequest request) Since successView and validationFailureView can contain multiple possible redirection paths using the format incomingRequestPath=outgoingRedirectPath, we'll need to identify which incomingRequestPath best matches the request that generated this validation, and then return the view name (outgoingRedirectPath) associated with that path.
static String[]	getControllerRequestPaths(org.springframework.web.method.HandlerMethod handler) Given a handler object, return the base controller class-level requestMapping paths.
static javax.servlet.http.HttpServletRequest	getRequest()
static Map	getRequestParameters()
static boolean	isWebflowRequest()
static String	removeLeadingAndTrailingSlashes(String path) Removes the leading and trailing slashes from a url path.
static String	replaceRestPathVariables(String viewName, Map<String,Object> model, javax.servlet.http.HttpServletRequest request) Used by successView and validationFailureView.

Method Detail

getRequest

public static javax.servlet.http.HttpServletRequest getRequest()

Returns:

the current thread-bound HttpServletRequest

getRequestParameters

public static Map getRequestParameters()

replaceRestPathVariables

public static String replaceRestPathVariables(String viewName,
                                              Map<String,Object> model,
                                              javax.servlet.http.HttpServletRequest request)

Used by successView and validationFailureView. If the user specifies a path containing RESTful url wildcards, evaluate those wildcard expressions against the current model map, and plug them into the url. If the wildcard is a multisegmented path, get the top level bean from the model map, and fetch the sub path using a beanwrapper instance.

Parameters:

viewName - The view potentially containing wildcards

model - the model map

request - the request

Returns:

a wildcard-substituted view name

findMatchingRestPath

public static String findMatchingRestPath(String[] candidateViewNames,
                                          String[] controllerPaths,
                                          javax.servlet.http.HttpServletRequest request)

Since successView and validationFailureView can contain multiple possible redirection paths using the format incomingRequestPath=outgoingRedirectPath, we'll need to identify which incomingRequestPath best matches the request that generated this validation, and then return the view name (outgoingRedirectPath) associated with that path. This is made simple by looking for the bestMatchingPattern that spring has already kindly exposed in the request attributes.

Parameters:

candidateViewNames - The possible views

controllerPaths - The base path(s) from the controller

request - the request

Returns:

the best matching view name to redirect to.

getControllerRequestPaths

public static String[] getControllerRequestPaths(org.springframework.web.method.HandlerMethod handler)

Given a handler object, return the base controller class-level requestMapping paths. In case the controller specifies one or more base path(s).

Parameters:

handler - the handler object

Returns:

the controller request paths.

findHandlerAnnotation

public static Annotation findHandlerAnnotation(Class handlerClass,
                                               Class annotationClass)

Find an annotation on the possibly proxied handler.

Parameters:

handler - The handler / controller

annotationClass - The annotation to find.

Returns:

The annotation, or null if not present.

removeLeadingAndTrailingSlashes

public static String removeLeadingAndTrailingSlashes(String path)

Removes the leading and trailing slashes from a url path.

Parameters:

path - the path

Returns:

the path without leading and trailing slashes.

isWebflowRequest

public static boolean isWebflowRequest()

Returns:

true if the current web request is associated with Spring Web Flow.
