All Implemented Interfaces:

public class ExceptionHandlerExceptionResolver
extends AbstractHandlerMethodExceptionResolver
implements org.springframework.context.ApplicationContextAware, org.springframework.beans.factory.InitializingBean

An AbstractHandlerMethodExceptionResolver that resolves exceptions through @ExceptionHandler methods.

Support for custom argument and return value types can be added via setCustomArgumentResolvers(java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver>) and setCustomReturnValueHandlers(java.util.List<org.springframework.web.method.support.HandlerMethodReturnValueHandler>). Or alternatively to re-configure all argument and return value types use setArgumentResolvers(java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver>) and setReturnValueHandlers(List).

Since:

3.1

Method Details

setCustomArgumentResolvers

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

getCustomArgumentResolvers

@Nullable
public List<org.springframework.web.method.support.HandlerMethodArgumentResolver> getCustomArgumentResolvers()

Return the custom argument resolvers, or null.

setArgumentResolvers

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

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

getArgumentResolvers

@Nullable
public org.springframework.web.method.support.HandlerMethodArgumentResolverComposite getArgumentResolvers()

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

setCustomReturnValueHandlers

public void setCustomReturnValueHandlers(@Nullable
 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>).

getCustomReturnValueHandlers

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

Return the custom return value handlers, or null.

setReturnValueHandlers

public void setReturnValueHandlers(@Nullable
 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.

getReturnValueHandlers

@Nullable
public org.springframework.web.method.support.HandlerMethodReturnValueHandlerComposite getReturnValueHandlers()

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

setMessageConverters

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

Set the message body converters to use.

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

getMessageConverters

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

Return the configured message body converters.

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.

getContentNegotiationManager

public org.springframework.web.accept.ContentNegotiationManager getContentNegotiationManager()

Return the configured ContentNegotiationManager.

setResponseBodyAdvice

public void setResponseBodyAdvice(@Nullable
 List<ResponseBodyAdvice<?>> 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.

setApplicationContext

public void setApplicationContext(@Nullable
 org.springframework.context.ApplicationContext applicationContext)

Specified by:

setApplicationContext in interface org.springframework.context.ApplicationContextAware

getApplicationContext

@Nullable
public org.springframework.context.ApplicationContext getApplicationContext()

getExceptionHandlerAdviceCache

public Map<org.springframework.web.method.ControllerAdviceBean,org.springframework.web.method.annotation.ExceptionHandlerMethodResolver> 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 List<org.springframework.web.method.support.HandlerMethodArgumentResolver> getDefaultArgumentResolvers()

Return the list of argument resolvers to use including built-in resolvers and custom resolvers provided via setCustomArgumentResolvers(java.util.List<org.springframework.web.method.support.HandlerMethodArgumentResolver>).

Return the list of return value handlers to use including built-in and custom handlers provided via setReturnValueHandlers(java.util.List<org.springframework.web.method.support.HandlerMethodReturnValueHandler>).

hasGlobalExceptionHandlers

protected boolean hasGlobalExceptionHandlers()

Description copied from class: AbstractHandlerMethodExceptionResolver

Whether this resolver has global exception handlers, e.g. 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(HttpServletRequest request,
 @Nullable
 Object handler)

Description copied from class: AbstractHandlerMethodExceptionResolver

Checks if the handler is a HandlerMethod and then delegates to the base class implementation of #shouldApplyTo(HttpServletRequest, Object) passing the bean of the HandlerMethod. 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:

• AbstractHandlerExceptionResolver.setMappedHandlers(java.util.Set<?>)
• AbstractHandlerExceptionResolver.setMappedHandlerClasses(java.lang.Class<?>...)

doResolveHandlerMethodException

@Nullable
protected ModelAndView doResolveHandlerMethodException(HttpServletRequest request,
 HttpServletResponse response,
 @Nullable
 org.springframework.web.method.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

Returns:

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

getExceptionHandlerMethod

@Nullable
protected ServletInvocableHandlerMethod getExceptionHandlerMethod(@Nullable
 org.springframework.web.method.HandlerMethod handlerMethod,
 Exception exception)

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

Returns:

a method to handle the exception, or null if none
