Configure the complete list of supported argument types thus overriding the resolvers that would otherwise be configured by default.

Overrides:

setArgumentResolvers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

getArgumentResolvers

@Nullable
public java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver> getArgumentResolvers()

Return the configured argument resolvers, or possibly null if not initialized yet via afterPropertiesSet().

Overrides:

getArgumentResolvers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setInitBinderArgumentResolvers

public void setInitBinderArgumentResolvers(@Nullable
                                           java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver> argumentResolvers)

Configure the supported argument types in @InitBinder methods.

Overrides:

setInitBinderArgumentResolvers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

getInitBinderArgumentResolvers

@Nullable
public java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver> getInitBinderArgumentResolvers()

Return the argument resolvers for @InitBinder methods, or possibly null if not initialized yet via afterPropertiesSet().

Overrides:

getInitBinderArgumentResolvers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setCustomReturnValueHandlers

public void setCustomReturnValueHandlers(@Nullable
                                         java.util.List<org.springframework.web.method.support.HandlerMethodReturnValueHandler> returnValueHandlers)

Provide handlers for custom return value types. Custom handlers are ordered after built-in ones. To override the built-in support for return value handling use setReturnValueHandlers(java.util.List<org.springframework.web.method.support.HandlerMethodReturnValueHandler>).

Overrides:

setCustomReturnValueHandlers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

getCustomReturnValueHandlers

@Nullable
public java.util.List<org.springframework.web.method.support.HandlerMethodReturnValueHandler> getCustomReturnValueHandlers()

Return the custom return value handlers, or null.

Overrides:

getCustomReturnValueHandlers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setReturnValueHandlers

public void setReturnValueHandlers(@Nullable
                                   java.util.List<org.springframework.web.method.support.HandlerMethodReturnValueHandler> returnValueHandlers)

Configure the complete list of supported return value types thus overriding handlers that would otherwise be configured by default.

Overrides:

setModelAndViewResolvers

public void setModelAndViewResolvers(@Nullable
                                     java.util.List<org.springframework.web.servlet.mvc.annotation.ModelAndViewResolver> modelAndViewResolvers)

Provide custom ModelAndViewResolvers.

Note: This method is available for backwards compatibility only. However, it is recommended to re-write a ModelAndViewResolver as HandlerMethodReturnValueHandler. An adapter between the two interfaces is not possible since the HandlerMethodReturnValueHandler.supportsReturnType(org.springframework.core.MethodParameter) method cannot be implemented. Hence ModelAndViewResolvers are limited to always being invoked at the end after all other return value handlers have been given a chance.

A HandlerMethodReturnValueHandler provides better access to the return type and controller method information and can be ordered freely relative to other return value handlers.

Overrides:

setModelAndViewResolvers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

getModelAndViewResolvers

@Nullable
public java.util.List<org.springframework.web.servlet.mvc.annotation.ModelAndViewResolver> getModelAndViewResolvers()

Return the configured ModelAndViewResolvers, or null.

Overrides:

getModelAndViewResolvers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setContentNegotiationManager

public void setContentNegotiationManager(org.springframework.web.accept.ContentNegotiationManager contentNegotiationManager)

Set the ContentNegotiationManager to use to determine requested media types. If not set, the default constructor is used.

Overrides:

setContentNegotiationManager in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setMessageConverters

public void setMessageConverters(java.util.List<org.springframework.http.converter.HttpMessageConverter<?>> messageConverters)

Provide the converters to use in argument resolvers and return value handlers that support reading and/or writing to the body of the request and response.

Overrides:

setMessageConverters in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

getMessageConverters

public java.util.List<org.springframework.http.converter.HttpMessageConverter<?>> getMessageConverters()

Return the configured message body converters.

Overrides:

getMessageConverters in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setRequestBodyAdvice

public void setRequestBodyAdvice(@Nullable
                                 java.util.List<org.springframework.web.servlet.mvc.method.annotation.RequestBodyAdvice> requestBodyAdvice)

Add one or more RequestBodyAdvice instances to intercept the request before it is read and converted for @RequestBody and HttpEntity method arguments.

Overrides:

setRequestBodyAdvice in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setResponseBodyAdvice

public void setResponseBodyAdvice(@Nullable
                                  java.util.List<org.springframework.web.servlet.mvc.method.annotation.ResponseBodyAdvice<?>> responseBodyAdvice)

Overrides:

setResponseBodyAdvice in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setWebBindingInitializer

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

Provide a WebBindingInitializer with "global" initialization to apply to every DataBinder instance.

getWebBindingInitializer

@Nullable
public org.springframework.web.bind.support.WebBindingInitializer getWebBindingInitializer()

Return the configured WebBindingInitializer, or null if none.

Overrides:

getWebBindingInitializer in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setTaskExecutor

public void setTaskExecutor(org.springframework.core.task.AsyncTaskExecutor taskExecutor)

Set the default AsyncTaskExecutor to use when a controller method return a Callable. Controller methods can override this default on a per-request basis by returning an WebAsyncTask.

By default a SimpleAsyncTaskExecutor instance is used. It's recommended to change that default in production as the simple executor does not re-use threads.

Overrides:

setTaskExecutor in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setAsyncRequestTimeout

public void setAsyncRequestTimeout(long timeout)

Specify the amount of time, in milliseconds, before concurrent handling should time out. In Servlet 3, the timeout begins after the main request processing thread has exited and ends when the request is dispatched again for further processing of the concurrently produced result.

If this value is not set, the default timeout of the underlying implementation is used, e.g. 10 seconds on Tomcat with Servlet 3.

Overrides:

setAsyncRequestTimeout in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

Parameters:

timeout - the timeout value in milliseconds

setCallableInterceptors

public void setCallableInterceptors(java.util.List<org.springframework.web.context.request.async.CallableProcessingInterceptor> interceptors)

Configure CallableProcessingInterceptor's to register on async requests.

Overrides:

setCallableInterceptors in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

Parameters:

interceptors - the interceptors to register

setDeferredResultInterceptors

public void setDeferredResultInterceptors(java.util.List<org.springframework.web.context.request.async.DeferredResultProcessingInterceptor> interceptors)

Configure DeferredResultProcessingInterceptor's to register on async requests.

Overrides:

setDeferredResultInterceptors in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

Parameters:

interceptors - the interceptors to register

setReactiveAdapterRegistry

public void setReactiveAdapterRegistry(org.springframework.core.ReactiveAdapterRegistry reactiveAdapterRegistry)

Configure the registry for reactive library types to be supported as return values from controller methods.

Overrides:

setReactiveAdapterRegistry in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

Since:

5.0.5

getReactiveAdapterRegistry

public org.springframework.core.ReactiveAdapterRegistry getReactiveAdapterRegistry()

Return the configured reactive type registry of adapters.

Overrides:

getReactiveAdapterRegistry in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

Since:

5.0

setIgnoreDefaultModelOnRedirect

public void setIgnoreDefaultModelOnRedirect(boolean ignoreDefaultModelOnRedirect)

By default the content of the "default" model is used both during rendering and redirect scenarios. Alternatively a controller method can declare a RedirectAttributes argument and use it to provide attributes for a redirect.

Setting this flag to true guarantees the "default" model is never used in a redirect scenario even if a RedirectAttributes argument is not declared. Setting it to false means the "default" model may be used in a redirect if the controller method doesn't declare a RedirectAttributes argument.

The default setting is false but new applications should consider setting it to true.

Overrides:

setIgnoreDefaultModelOnRedirect in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

See Also:

RedirectAttributes

setSessionAttributeStore

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

Specify the strategy to store session attributes with. The default is DefaultSessionAttributeStore, storing session attributes in the HttpSession with the same attribute name as in the model.

Overrides:

setSessionAttributeStore in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setCacheSecondsForSessionAttributeHandlers

public void setCacheSecondsForSessionAttributeHandlers(int cacheSecondsForSessionAttributeHandlers)

Cache content produced by @SessionAttributes annotated handlers for the given number of seconds.

Possible values are:

• -1: no generation of cache-related headers
• 0 (default value): "Cache-Control: no-store" will prevent caching
• 1 or higher: "Cache-Control: max-age=seconds" will ask to cache content; not advised when dealing with session attributes

In contrast to the "cacheSeconds" property which will apply to all general handlers (but not to @SessionAttributes annotated handlers), this setting will apply to @SessionAttributes handlers only.

Overrides:

setCacheSecondsForSessionAttributeHandlers in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

See Also:

WebContentGenerator.setCacheSeconds(int), SessionAttributes

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 the handleRequestInternal 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.

Overrides:

setSynchronizeOnSession in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

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 DefaultParameterNameDiscoverer.

Overrides:

setParameterNameDiscoverer in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

setBeanFactory

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

A ConfigurableBeanFactory is expected for resolving expressions in method argument default values.

Specified by:

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

afterPropertiesSet in interface org.springframework.beans.factory.InitializingBean

Overrides:

afterPropertiesSet in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

supportsInternal

protected boolean supportsInternal(org.springframework.web.method.HandlerMethod handlerMethod)

Always return true since any method argument and return value type will be processed in some way. A method argument not recognized by any HandlerMethodArgumentResolver is interpreted as a request parameter if it is a simple type, or as a model attribute otherwise. A return value not recognized by any HandlerMethodReturnValueHandler will be interpreted as a model attribute.

Overrides:

supportsInternal in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

handleInternal

protected org.springframework.web.servlet.ModelAndView handleInternal(javax.servlet.http.HttpServletRequest request,
                                                                      javax.servlet.http.HttpServletResponse response,
                                                                      org.springframework.web.method.HandlerMethod handlerMethod)
                                                               throws java.lang.Exception

Overrides:

handleInternal in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

Throws:

getLastModifiedInternal

protected long getLastModifiedInternal(javax.servlet.http.HttpServletRequest request,
                                       org.springframework.web.method.HandlerMethod handlerMethod)

This implementation always returns -1. An @RequestMapping method can calculate the lastModified value, call WebRequest.checkNotModified(long), and return null if the result of that call is true.

Overrides:

getLastModifiedInternal in class org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter

invokeHandlerMethod

@Nullable
protected org.springframework.web.servlet.ModelAndView invokeHandlerMethod(javax.servlet.http.HttpServletRequest request,
                                                                                     javax.servlet.http.HttpServletResponse response,
                                                                                     org.springframework.web.method.HandlerMethod handlerMethod)
