protected abstract Object	handleInternal(RequestContext request, HandlerMethod handlerMethod, Throwable ex)	Actually resolve the given exception that got thrown during on handler execution, returning a view(result) that represents a specific error page if appropriate.

方法详细资料

shouldApplyTo

protected boolean shouldApplyTo(RequestContext request,
 @Nullable
 Object handler)

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.

覆盖:

shouldApplyTo 在类中 AbstractHandlerExceptionHandler

参数:

request - current HTTP request context

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

返回:

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

另请参阅:

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

hasGlobalExceptionHandlers

protected boolean hasGlobalExceptionHandlers()

Whether this handler 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.

handleInternal

@Nullable
protected Object handleInternal(RequestContext request,
 @Nullable
 Object handler,
 Throwable ex)
                         throws Exception

从类复制的说明: AbstractHandlerExceptionHandler

Actually handle the given exception that got thrown during handler execution, returning a result that represents a specific error page if appropriate.

May 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.

指定者:

handleInternal 在类中 AbstractHandlerExceptionHandler

参数:

request - current HTTP request context

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

ex - the exception that got thrown during handler execution

返回:

a corresponding Object view to forward to, or null for default processing in the resolution chain

抛出:

Exception

handleInternal

@Nullable
protected abstract Object handleInternal(RequestContext request,
 @Nullable
 HandlerMethod handlerMethod,
 Throwable ex)
                                  throws Exception

Actually resolve the given exception that got thrown during on handler execution, returning a view(result) that represents a specific error page if appropriate.

参数:

request - current HTTP request

handlerMethod - the executed handler method, 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

返回:

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

抛出:

Exception
