решил попробовать добавить обработку exception в spring mvc
зааннотировал метод:

Код

@ExceptionHandler({ SpringException.class })
    @RequestMapping(method = RequestMethod.GET, value = "/{candidateId}")
    public @ResponseBody
    Candidate findCandidateById(@PathVariable Integer candidateId) {
        ApplicationContext context = new ClassPathXmlApplicationContext(
                "spring/BeanConfig.xml");
        CandidateService candidateService = (CandidateService) context.getBean(
                "candidateService", CandidateService.class);
        Candidate candidate = candidateService.findById(candidateId);
 
        // return new ModelAndView(XML_VIEW_NAME,"candidates",candidates);
        if (candidate == null) {
        //try {
                throw new SpringException("don't found");
            /*} catch (SpringException exception) {
 
            }*/
        }
        return candidate;
    }

если срабатывает соответствующее исключению условие, то выводится нужная jsp(всё работает), то в консоль выводится следующее:
Код

подозреваю, что так не должно быть...

если раскомментарить обработку exception ничего - не происходит - пустая страничка просто, что наверное логично

Привет.
Согдасно документации Spring MVC (http://static.springsource.org/spring/docs/3.2.x/spring-framework-reference/html/mvc.html#mvc-ann-exceptionhandler), это должен быть отдельный метод. Так что дерзай.

Автор: redwhite90 12.7.2013, 13:51
написал так:
Код

@ExceptionHandler({ SpringException.class })
    public void foo() {
        throw new SpringException("not found");
    }

    // InvocableHandlerMethod
    @RequestMapping(method = RequestMethod.GET, value = "/{candidateId}")
    //@ExceptionHandler({ SpringException.class })
    public @ResponseBody
    Candidate findCandidateById(@PathVariable Integer candidateId) {
        foo();
        ApplicationContext context = new ClassPathXmlApplicationContext(
                "spring/BeanConfig.xml");
        CandidateService candidateService = (CandidateService) context.getBean(
                "candidateService", CandidateService.class);
        Candidate candidate = candidateService.findById(candidateId);

        // return new ModelAndView(XML_VIEW_NAME,"candidates",candidates);
        if (candidate == null) {
            // try {
            //throw new SpringException("not found");
            /*
             * } catch (SpringException exception) {
             * 
             * }
             */
        }
        return candidate;
    }


ничего не изменилось.... да и вообще можно так писать. я реализовал пример отсюда [http://www.tutorialspoint.com/spring/spring_exception_handling_example.htm]- всё вполне работоспособно.

только мне отличий принципиальных с этим кодом не найти.

Автор: MisterCleric 12.7.2013, 14:15
А кто тебе сказал, что тот пример работоспособен?
Как по мне, то все не правильно: @ExceptionHandler - это метод, который ловит Exception и пытается сделать какой-то рековери, как это делает HandlerExceptionResolver.
Читай лучше оригинальную доку, а не каких-то там "велосепидистов", которые на ряду с @ExceptionHandler еще конфигурят <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
Который в конечном итоге и преобразовывает твой SpringException во вью. Хотя ты мог бы это смело сделать в этом методе. Вот только правильно надо замеппиться...
Было бы хорошо, если бы ты в дебаге посмотрел, что приходит тебе на вход.
Хотя по исходникам явно видно, что 
Код

exceptionHandlerMethod.invokeAndHandle(webRequest, mavContainer, exception);

Т.е. Exception должен быть агрументом этого метода.

то есть можно только через аннотацию это замапить и без всего остального?

Добавлено через 7 минут и 59 секунд
если закоментировать 
Код

 <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
, то будет
