All Implemented Interfaces:
  InitializingBean, Ordered, HandlerExceptionResolver

    public class ExceptionHandlerExceptionResolver

extends AbstractHandlerMethodExceptionResolver
implements 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)`.

Constructor Detail

### ExceptionHandlerExceptionResolver

    public ExceptionHandlerExceptionResolver()

  Default constructor.

Method Detail

### setCustomArgumentResolvers

    public void setCustomArgumentResolvers(List<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

    public List<HandlerMethodArgumentResolver> getCustomArgumentResolvers()

  Return the custom argument resolvers, or `null`.

### setArgumentResolvers

    public void setArgumentResolvers(List<HandlerMethodArgumentResolver> argumentResolvers)

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

### getArgumentResolvers

    public HandlerMethodArgumentResolverComposite getArgumentResolvers()

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

### setCustomReturnValueHandlers

    public void setCustomReturnValueHandlers(List<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

    public List<HandlerMethodReturnValueHandler> getCustomReturnValueHandlers()

  Return the custom return value handlers, or `null`.

### setReturnValueHandlers

    public void setReturnValueHandlers(List<HandlerMethodReturnValueHandler> returnValueHandlers)

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

### getReturnValueHandlers

    public HandlerMethodReturnValueHandlerComposite getReturnValueHandlers()

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

### setMessageConverters

    public void setMessageConverters(List<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<HttpMessageConverter<?>> getMessageConverters()

  Return the configured message body converters.

### afterPropertiesSet

    public void afterPropertiesSet()

  Description copied from interface: `InitializingBean`
  Invoked by a BeanFactory after it has set all bean properties supplied (and satisfied BeanFactoryAware and ApplicationContextAware).

  This method allows the bean instance to perform initialization only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

  Specified by:
    `afterPropertiesSet` in interface `InitializingBean`

### getDefaultArgumentResolvers

    protected List<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>)`.

### getDefaultReturnValueHandlers

    protected List<HandlerMethodReturnValueHandler> getDefaultReturnValueHandlers()

  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>)`.

### doResolveHandlerMethodException

    protected ModelAndView doResolveHandlerMethodException(HttpServletRequest request,
                                                           HttpServletResponse response,
                                                           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

    protected ServletInvocableHandlerMethod getExceptionHandlerMethod(HandlerMethod handlerMethod,
                                                                      Exception exception)

  Find the @`ExceptionHandler` method for the given exception. The default implementation searches @`ExceptionHandler` methods in the class hierarchy of the method that raised the exception.

  Parameters:
    `handlerMethod` - the method where the exception was raised
    `exception` - the raised exception
  Returns:
    a method to handle the exception, or `null`
