Method Detail

setConventionHelper

public void setConventionHelper(ConventionHelper conventionHelper)

getBeanFactory

public org.springframework.beans.factory.config.ConfigurableBeanFactory getBeanFactory()

setBeanFactory

public void setBeanFactory(org.springframework.beans.factory.BeanFactory beanFactory)

Specified by:

setBeanFactory in interface org.springframework.beans.factory.BeanFactoryAware

getExpressionContext

public org.springframework.beans.factory.config.BeanExpressionContext getExpressionContext()

getUrlPathHelper

public org.springframework.web.util.UrlPathHelper getUrlPathHelper()

setUrlPathHelper

public void setUrlPathHelper(org.springframework.web.util.UrlPathHelper urlPathHelper)

Set the UrlPathHelper to use for resolution of lookup paths.

Use this to override the default UrlPathHelper with a custom subclass, or to share common UrlPathHelper settings across multiple HandlerMappings and HandlerAdapters.

getPathMatcher

public org.springframework.util.PathMatcher getPathMatcher()

setPathMatcher

public void setPathMatcher(org.springframework.util.PathMatcher pathMatcher)

Set the PathMatcher implementation to use for matching URL paths against registered URL patterns. Default is AntPathMatcher.

See Also:

AntPathMatcher

getMethodInvokePreHandlerComposite

public MethodInvokePreHandlerComposite getMethodInvokePreHandlerComposite()

setMethodInvokePreHandlerComposite

public void setMethodInvokePreHandlerComposite(MethodInvokePreHandlerComposite methodInvokePreHandlerComposite)

getHttpMessageConverterComposite

public HttpMessageConverterComposite getHttpMessageConverterComposite()

setHttpMessageConverterComposite

public void setHttpMessageConverterComposite(HttpMessageConverterComposite httpMessageConverterComposite)

setCustomModelAndViewResolver

public void setCustomModelAndViewResolver(org.springframework.web.servlet.mvc.annotation.ModelAndViewResolver customModelAndViewResolver)

getCustomModelAndViewResolvers

public org.springframework.web.servlet.mvc.annotation.ModelAndViewResolver[] getCustomModelAndViewResolvers()

setCustomModelAndViewResolvers

public void setCustomModelAndViewResolvers(org.springframework.web.servlet.mvc.annotation.ModelAndViewResolver[] customModelAndViewResolvers)

setAlwaysUseFullPath

public void setAlwaysUseFullPath(boolean alwaysUseFullPath)

Set if URL lookup should always use the full path within the current servlet context. Else, the path within the current servlet mapping is used if applicable (that is, in the case of a ".../*" servlet mapping in web.xml).

Default is "false".

See Also:

UrlPathHelper.setAlwaysUseFullPath(boolean)

setUrlDecode

public void setUrlDecode(boolean urlDecode)

Set if context path and request URI should be URL-decoded. Both are returned undecoded by the Servlet API, in contrast to the servlet path.

Uses either the request encoding or the default encoding according to the Servlet spec (ISO-8859-1).

See Also:

UrlPathHelper.setUrlDecode(boolean)

setMethodNameResolver

public void setMethodNameResolver(org.springframework.web.servlet.mvc.multiaction.MethodNameResolver methodNameResolver)

Set the MethodNameResolver to use for resolving default handler methods (carrying an empty @RequestMapping annotation).

Will only kick in when the handler method cannot be resolved uniquely through the annotation metadata already.

setWebBindingInitializer

public void setWebBindingInitializer(org.springframework.web.bind.support.WebBindingInitializer webBindingInitializer)

Specify a WebBindingInitializer which will apply pre-configured configuration to every DataBinder that this controller uses.

setSessionAttributeStore

public void setSessionAttributeStore(org.springframework.web.bind.support.SessionAttributeStore sessionAttributeStore)

Specify the strategy to store session attributes with.

Default is DefaultSessionAttributeStore , storing session attributes in the HttpSession, using the same attribute name as in the model.

setSynchronizeOnSession

public void setSynchronizeOnSession(boolean synchronizeOnSession)

Set if controller execution should be synchronized on the session, to serialize parallel invocations from the same client.

More specifically, the execution of each handler method will get synchronized if this flag is "true". The best available session mutex will be used for the synchronization; ideally, this will be a mutex exposed by HttpSessionMutexListener.

The session mutex is guaranteed to be the same object during the entire lifetime of the session, available under the key defined by the SESSION_MUTEX_ATTRIBUTE constant. It serves as a safe reference to synchronize on for locking on the current session.

In many cases, the HttpSession reference itself is a safe mutex as well, since it will always be the same object reference for the same active logical session. However, this is not guaranteed across different servlet containers; the only 100% safe way is a session mutex.

See Also:

HttpSessionMutexListener, WebUtils.getSessionMutex(javax.servlet.http.HttpSession)

setParameterNameDiscoverer

public void setParameterNameDiscoverer(org.springframework.core.ParameterNameDiscoverer parameterNameDiscoverer)

Set the ParameterNameDiscoverer to use for resolving method parameter names if needed (e.g. for default attribute names).

Default is a LocalVariableTableParameterNameDiscoverer.

setCustomArgumentResolver

public void setCustomArgumentResolver(org.springframework.web.bind.support.WebArgumentResolver argumentResolver)

Set a custom ArgumentResolvers to use for special method parameter types. Such a custom ArgumentResolver will kick in first, having a chance to resolve an argument value before the standard argument handling kicks in.

setCustomArgumentResolvers

public void setCustomArgumentResolvers(org.springframework.web.bind.support.WebArgumentResolver[] argumentResolvers)

Set one or more custom ArgumentResolvers to use for special method parameter types. Any such custom ArgumentResolver will kick in first, having a chance to resolve an argument value before the standard argument handling kicks in.

getLastModified

public long getLastModified(javax.servlet.http.HttpServletRequest request,
                            Object handler)

Specified by:

getLastModified in interface org.springframework.web.servlet.HandlerAdapter

Handle the case where no request handler method was found.

The default implementation logs a warning and sends an HTTP 404 error. Alternatively, a fallback view could be chosen, or the NoSuchRequestHandlingMethodException could be rethrown as-is.

Parameters:

ex - the NoSuchRequestHandlingMethodException to be handled

request - current HTTP request

response - current HTTP response

Returns:

a ModelAndView to render, or null if handled directly

Throws:

Exception - an Exception that should be thrown as result of the servlet request
