问题 I know a lot has been discussed around exception handling, however I need some advice specific to my situation. I am currently working on a Spring MVC application with Controller->Services->DAO layers. The service classes catch mainly two kinds of exceptions HibernateException and IOException . HibernateException because service needs to perform rollback if a transaction did not succeed and IOException since it is an unchecked exception and needs to be caught or thrown and I prefer the first

问题 I have set up i18n in Spring MVC 3, and it is working correctly. There are several files, each with its own language: messages_en.properties, messages_de.properties, etc. In one of my JSPs, I need to show the users a combo with all available languages, and I would like this list to be dynamic i.e. generated on the fly from the existing language files in the server. Is there any built-in method to generate this list? Or do I have to resort to check the folder where the language files reside

问题 This is continuation of this question: Return @Async method result in Spring MVC and return it to Ajax client I have @Async task which calculates something and return it to the Future the calculation happens on the request and might take up to 15 minutes.

What might be the best solution for Spring MVC in such

问题 I want to create a pointcut that matches any method in my Web controller that contains a ModelMap: pointcut addMenu(ModelMap modelMap) : execution (public String example.web.MyController.*(..)) && args (modelMap); before(ModelMap modelMap) : addMenu(modelMap) { // Do stuff with modelMap... } My problem is that this only matches methods with ONLY the ModelMap parameter, others are not matched because they contain too many parameters. For example, this is not intercepted, due to the "req"

问题 I'm trying to call a method in Spring-powered bean asynchronously using @Async . I defined an executor in XML: <task:executor id="emailTasksExecutor" pool-size="1" /> and here is my method: @Override @Async("emailTasksExecutor") public void sendEmail() { ... } And the method does not get called at all when I use qualifier ( emailTasksExecutor ). However, if I remove it, everything works ok. But in this case the default executor is used and I need to change this behaviour. I thought the
