从类复制的说明: AbstractActionMappingMethodExceptionHandler

Actually resolve the given exception that got thrown during on handler execution, returning a view(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 AbstractActionMappingMethodExceptionHandler

参数:

context - 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:

抛出:

Exception

writeErrorMessage

protected void writeErrorMessage(Throwable ex,
 RequestContext context)
                          throws IOException

Write error message to request context, default is write json

参数:

ex - Throwable that occurred in request handler

context - current request context

抛出:

getErrorStatusValue
