无法在 Runnable 或 Spring Controller 中实例化 EWS ExchangeService

Question

我在 TimerTask 中有一个 EWS 服务，但它在实例化 new ExchangeService(ExchangeVersion.Exchange2010_SP2) 时抛出异常，并且它在 spring-web-mvc Controller 方法中不起作用，该方法使用 @RequestMapping 但实例化在 Non-Runnable Class.

中工作得很好

public class AutoEmailTicketing extends TimerTask {
    @Override
    public void run() {
        microsoft.exchange.webservices.data.ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
        service.setCredentials(new WebCredentials(email, password));
        service.autodiscoverUrl(email, new RedirectionUrlCallback());
        service.setTraceEnabled(true);
        Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox);
    }
}

用过的罐子...

终于在Here找到了解决办法。我用过...

httpclient-4.2.jar
httpcore-4.2.jar
joda-time-2.9.9.jar

不知道joda-time靠不靠
