All Implemented Interfaces:

Aware, InitializingBean, ApplicationContextAware, Ordered, HandlerExceptionResolver

public class ExceptionHandlerExceptionResolver
extends AbstractHandlerMethodExceptionResolver
implements ApplicationContextAware, InitializingBean

An AbstractHandlerMethodExceptionResolver that resolves exceptions through @ExceptionHandler methods.

support for custom argument and return value types can be added via setCustomArgumentResolvers(List) and setCustomReturnValueHandlers(List). Or alternatively to re-configure all argument and return value types use setArgumentResolvers(List) and setReturnValueHandlers(List).

Method Details

setCustomArgumentResolvers

public&nbsp;void&nbsp;setCustomArgumentResolvers(@Nullable List<HandlerMethodArgumentResolver>&nbsp;argumentResolvers)

Provide resolvers for custom argument types. Custom resolvers are ordered after built-in ones. To override the built-in support for argument resolution use setArgumentResolvers(List) instead.

public&nbsp;@Nullable List<HandlerMethodArgumentResolver>&nbsp;getCustomArgumentResolvers()

Return the custom argument resolvers, or null.

setArgumentResolvers

public&nbsp;void&nbsp;setArgumentResolvers(@Nullable List<HandlerMethodArgumentResolver>&nbsp;argumentResolvers)

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

getArgumentResolvers

public @Nullable HandlerMethodArgumentResolverComposite getArgumentResolvers()

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

setCustomReturnValueHandlers

public&nbsp;void&nbsp;setCustomReturnValueHandlers(@Nullable List<HandlerMethodReturnValueHandler>&nbsp;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(List).

getCustomReturnValueHandlers

public&nbsp;@Nullable List<HandlerMethodReturnValueHandler>&nbsp;getCustomReturnValueHandlers()

Return the custom return value handlers, or null.

setReturnValueHandlers

public&nbsp;void&nbsp;setReturnValueHandlers(@Nullable List<HandlerMethodReturnValueHandler>&nbsp;returnValueHandlers)

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

getReturnValueHandlers

public @Nullable HandlerMethodReturnValueHandlerComposite getReturnValueHandlers()

Return the configured handlers, or possibly null if not initialized yet via afterPropertiesset().

setMessageConverters

public&nbsp;void&nbsp;setMessageConverters(List<HttpMessageConverter<?>>&nbsp;messageConverters)

set the message body converters to use.

These converters are used to convert from and to HTTP requests and responses.

getMessageConverters

public&nbsp;List<HttpMessageConverter<?>>&nbsp;getMessageConverters()

Return the configured message body converters.

setContentNegotiationManager

public void setContentNegotiationManager(ContentNegotiationManager contentNegotiationManager)

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

getContentNegotiationManager

public ContentNegotiationManager getContentNegotiationManager()

Return the configured ContentNegotiationManager.

setResponseBodyAdvice

public&nbsp;void&nbsp;setResponseBodyAdvice(@Nullable List<ResponseBodyAdvice<?>>&nbsp;responseBodyAdvice)

Add one or more components to be invoked after the execution of a controller method annotated with @ResponseBody or returning ResponseEntity but before the body is written to the response with the selected HttpMessageConverter.

setErrorResponseInterceptors

public&nbsp;void&nbsp;setErrorResponseInterceptors(List<ErrorResponse.Interceptor>&nbsp;interceptors)

Configure a list of ErrorResponse.Interceptor's to apply when rendering an RFC 9457 ProblemDetail error response.

Parameters:

interceptors - the handlers to use

setApplicationContext

public void setApplicationContext(@Nullable ApplicationContext applicationContext)

Description copied from interface: ApplicationContextAware

set the ApplicationContext that this object runs in. Normally this call will be used to initialize the object.

Invoked after population of normal bean properties but before an init callback such as InitializingBean.afterPropertiesset() or a custom init-method. Invoked after ResourceLoaderAware.setResourceLoader(ResourceLoader), ApplicationEventPublisherAware.setApplicationEventPublisher(ApplicationEventPublisher) and MessagesourceAware, if applicable.

specified by:

setApplicationContext in interface ApplicationContextAware

Parameters:

applicationContext - the ApplicationContext object to be used by this object

see Also:

• BeanInitializationException

getApplicationContext

public @Nullable ApplicationContext getApplicationContext()

afterPropertiesset

public void afterPropertiesset()

Description copied from interface: InitializingBean

Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

specified by:

afterPropertiesset in interface InitializingBean

getExceptionHandlerAdviceCache

public&nbsp;Map<ControllerAdviceBean, ExceptionHandlerMethodResolver>&nbsp;getExceptionHandlerAdviceCache()

Return an unmodifiable Map with the @ControllerAdvice beans discovered in the ApplicationContext. The returned map will be empty if the method is invoked before the bean has been initialized via afterPropertiesset().

getDefaultArgumentResolvers

protected&nbsp;List<HandlerMethodArgumentResolver>&nbsp;getDefaultArgumentResolvers()

Return the list of argument resolvers to use including built-in resolvers and custom resolvers provided via setCustomArgumentResolvers(List).

getDefaultReturnValueHandlers

protected&nbsp;List<HandlerMethodReturnValueHandler>&nbsp;getDefaultReturnValueHandlers()

Return the list of return value handlers to use including built-in and custom handlers provided via setReturnValueHandlers(List).

hasGlobalExceptionHandlers

protected boolean hasGlobalExceptionHandlers()

Description copied from class: AbstractHandlerMethodExceptionResolver

Whether this resolver has global exception handlers, for example, not declared in the same class as the HandlerMethod that raised the exception and therefore can apply to any handler.

Overrides:

hasGlobalExceptionHandlers in class AbstractHandlerMethodExceptionResolver

shouldApplyTo

protected boolean shouldApplyTo(jakarta.servlet.http.HttpservletRequest request,
 @Nullable Object handler)

Description copied from class: AbstractHandlerMethodExceptionResolver

Checks if the handler is a HandlerMethod or the resolver has global exception handlers and then delegates to the base class implementation of #shouldApplyTo passing the bean of the HandlerMethod if necessary. Otherwise, returns false.

Overrides:

shouldApplyTo in class AbstractHandlerMethodExceptionResolver

Parameters:

request - current HTTP request

handler - the executed handler, or null if none chosen at the time of the exception (for example, if multipart resolution failed)

Returns:

whether this resolved should proceed with resolving the exception for the given request and handler

see Also:

• HandlerMethod
• AbstractHandlerMethodExceptionResolver.hasGlobalExceptionHandlers()

doResolveHandlerMethodException

protected @Nullable ModelAndView doResolveHandlerMethodException(jakarta.servlet.http.HttpservletRequest request,
 jakarta.servlet.http.HttpservletResponse response,
 @Nullable HandlerMethod handlerMethod,
 Exception exception)

Find an @ExceptionHandler method and invoke it to handle the raised exception.

specified by:

doResolveHandlerMethodException in class AbstractHandlerMethodExceptionResolver

Parameters:

request - current HTTP request

response - current HTTP response

handlerMethod - the executed handler method, or null if none chosen at the time of the exception (for example, if multipart resolution failed)

exception - the exception that got thrown during handler execution

a corresponding ModelAndView to forward to, or null for default processing

getExceptionHandlerMethod

protected @Nullable servletInvocableHandlerMethod getExceptionHandlerMethod(@Nullable HandlerMethod handlerMethod,
 Exception exception,
 servletWebRequest webRequest)

Find an @ExceptionHandler method for the given exception. The default implementation searches methods in the class hierarchy of the controller first and if not found, it continues searching for additional @ExceptionHandler methods assuming some @ControllerAdvice spring-managed beans were detected.

Parameters:

handlerMethod - the method where the exception was raised (may be null)

exception - the raised exception

webRequest - the original web request that resulted in a handler error

Returns:

a method to handle the exception, or null if none
