java - ExceptionHandler doesn't work with Throwable -

ours spring mvc based rest application. trying use exceptionhandler annotation handle errors , exceptions.

i have

    @exceptionhandler(throwable.class)     public @responsebody string handleerrors() {         return "error";     } 

this works whenever there exception thrown , doesn't work errors.

i using spring 4.0. there work-around?

contrary exceptionhandler#value() attribute indicates

class<? extends throwable>[] value() default {}; 

and @exceptionhandler meant handle exception , sub types.

spring uses exceptionhandlerexceptionresolver resolve annotated handlers, using following method

doresolvehandlermethodexception(httpservletrequest request,         httpservletresponse response, handlermethod handlermethod, exception exception)  

which can see accepts exception.

you cannot handle throwable or error types @exceptionhandler configuration.

i tell provide own handlerexceptionresolver implementation handle throwable instances, you'd need provide own dispatcherservlet (and of mvc stack) since dispatcherservlet not catch throwable instances @ place make significant difference.

update:

since 4.3, spring mvc wraps thrown throwable value in nestedservletexception instance , exposes exceptionhandlerexceptionresolver.
