Returns the value of the "grails.mime.file.extensions" setting configured in COnfig.groovy
Removes any GrailsWebRequest instance from the current request.
Expose the current request URI and paths as javax.servlet.http.HttpServletRequest
attributes under the keys defined in the Servlet 2.4 specification,
for containers that implement 2.3 or an earlier version of the Servlet API:
javax.servlet.forward.request_uri,
javax.servlet.forward.context_path,
javax.servlet.forward.servlet_path,
javax.servlet.forward.path_info,
javax.servlet.forward.query_string.
Does not override values if already present, to not cause conflicts with the attributes exposed by Servlet 2.4+ containers themselves.
request - current servlet requestLocates the ApplicationContext, returns null if not found
servletContext - The servlet contextTakes a query string and returns the results as a map where the values are either a single entry or a list of values
queryString - The query String Obtains the format from the URI. The format is the string following the . file extension in the last token of the URI.
If nothing comes after the ".", this method assumes that there is no format and returns null.
uri - The URI Obtains the format from the URI. The format is the string following the . file extension in the last token of the URI.
If nothing comes after the ".", this method assumes that there is no format and returns null.
uri - The URImimeTypes - The configured mime typesObtains the forwardURI from the request, since Grails uses a forwarding technique for URL mappings. The actual request URI is held within a request attribute
request - The requestThe Grails dispatch servlet maps URIs like /app/grails/example/index.dispatch. This method infers the controller URI for the dispatch URI so that /app/grails/example/index.dispatch becomes /app/example/index
request - The requestLooks up the GrailsApplication instance
Looks up all of the HandlerInterceptor instances registered for the application
servletContext - The ServletContext instanceLooks up all of the WebRequestInterceptor instances registered with the application
servletContext - The ServletContext instanceResolves a view for the given view name and controller name
request - The requestviewName - The view namecontrollerName - The controller nameviewResolver - The resolverReturns the GrailsWebRequest associated with the current request. This is the preferred means of accessing the GrailsWebRequest instance. If the exception is undesired, you can use RequestContextHolder.getRequestAttributes() instead.
Helper method to store the given GrailsWebRequest for the current request. Ensures consistency between RequestContextHolder and the relevant request attribute. This is the preferred means of updating the current web request.
Converts the given params into a query string started with ?
params - The paramsencoding - The encoding to useConverts the given parameters to a query string using the default UTF-8 encoding
parameters - The parameters
