All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected ModelAndView`	`doResolveException(PortletRequest request, MimeResponse response, Object handler, Exception ex)`	Actually resolve the given exception that got thrown during on handler execution, returning a ModelAndView that represents a specific error page if appropriate.
`protected List<Class<? extends Throwable>>`	`getHandledExceptions(Method method)`	Returns all the exception classes handled by the given method.
`protected Object`	`resolveCommonArgument(MethodParameter methodParameter, NativeWebRequest webRequest, Exception thrownException)`	Resolves common method arguments.
`protected Object`	`resolveStandardArgument(Class<?> parameterType, NativeWebRequest webRequest, Exception thrownException)`	Resolves standard method arguments.
`void`	`setCustomArgumentResolver(WebArgumentResolver argumentResolver)`	Set a custom ArgumentResolvers to use for special method parameter types.
`void`	`setCustomArgumentResolvers(WebArgumentResolver[] argumentResolvers)`	Set one or more custom ArgumentResolvers to use for special method parameter types.

  - setCustomArgumentResolver
```
public void setCustomArgumentResolver(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(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.
  - doResolveException
```
protected ModelAndView doResolveException(PortletRequest request,
                                          MimeResponse response,
                                          Object handler,
                                          Exception ex)
```
    Description copied from class: AbstractHandlerExceptionResolver
    Actually resolve the given exception that got thrown during on handler execution, returning a ModelAndView that represents a specific error page if appropriate.
    Must be overridden in subclasses, in order to apply specific exception checks. Note that this template method will be invoked after checking whether this resolved applies ("mappedHandlers" etc), so an implementation may simply proceed with its actual exception handling.
    Specified by:
    doResolveException in class AbstractHandlerExceptionResolver
    Parameters:
    request - current portlet request
    response - current portlet response
    handler - the executed handler, or null if none chosen at the time of the exception (for example, if multipart resolution failed)
    ex - the exception that got thrown during handler execution
    Returns:
    a corresponding ModelAndView to forward to, or null for default processing
  - getHandledExceptions
```
protected List<Class<? extends Throwable>> getHandledExceptions(Method method)
```
    Returns all the exception classes handled by the given method.
    Default implementation looks for exceptions in the annotation, or - if that annotation element is empty - any exceptions listed in the method parameters if the method is annotated with @ExceptionHandler.
    Parameters:
    method - the method
    Returns:
    the handled exceptions
  - resolveCommonArgument
```
protected Object resolveCommonArgument(MethodParameter methodParameter,
                                       NativeWebRequest webRequest,
                                       Exception thrownException)
                                throws Exception
```
    Resolves common method arguments. Delegates to registered argumentResolvers first, then checking resolveStandardArgument(java.lang.Class<?>, org.springframework.web.context.request.NativeWebRequest, java.lang.Exception).
    Parameters:
    methodParameter - the method parameter
    webRequest - the request
    thrownException - the exception thrown
    Returns:
    the argument value, or WebArgumentResolver.UNRESOLVED
    Throws:
    Exception
  - resolveStandardArgument
```
protected Object resolveStandardArgument(Class<?> parameterType,
                                         NativeWebRequest webRequest,
                                         Exception thrownException)
                                  throws Exception
```
    Resolves standard method arguments. The default implementation handles NativeWebRequest, ServletRequest, ServletResponse, HttpSession, Principal, Locale, request InputStream, request Reader, response OutputStream, response Writer, and the given thrownException.
    Parameters:
    parameterType - the method parameter type
    webRequest - the request
    thrownException - the exception thrown
    Returns:
    the argument value, or WebArgumentResolver.UNRESOLVED
    Throws:
    Exception
