I have a couple of SYSOUTs in my controller's methods, and they appear in the console log... verifying for me that all of the @RequestMapping is behaving as expected. The @Autowiring of an environment bean is also working (is also correctly displayed by a SYSOUT). However, the methods' returns (I am using methods that return String type) are only resulting in 404s. The *.jsps aren'
我在控制器的方法中有几个SYSOUT，并且它们出现在控制台日志中...为我验证所有@RequestMapping的行为如预期。 环境bean的@Autowiring也在工作（也可以通过SYSOUT正确显示）。 但是，方法的返回值（我使用的是返回String类型的方法）只会导致404s。 未找到* .jsps。 项目正在使用Maven; IDE是eclipse kepler，FWIW。 我的ViewResolver是沼气标准。 看不到断开连接。 我的web.xml： <?xml version="1.0"

我试图与亚马逊MWS订购，但遇到了一些问题。 是的，我已经用他们的MSW暂存器测试过了，并得到了结果。 但是现在我试图在我的浏览器中输入他们的“字符串来签名”得到这个： 参数签名不能为空。 所以我去使用Amazons代码来计算签名，并生成我自己的“签名字符串”，这就是我所得到的，我的凭据都很好，从scratchpad复制。 如果它在那里工作，它必须在这里工作？ 不。 我只改变了这段代码： parameters.put("Action", urlEnc

My app will access a webservice to access data (even if the application is not in foreground), every 10 minutes. What is the best way to do that? First do I need to start my service in seaparate thread? And how to make it get update from server every 10 minutes? Some people said handler.postdelayed and some using Alarm Manager. which one is better and do we have some examples. If the upda
我的应用程序将每10分钟访问一次web服务以访问数据（即使应用程序不在前台）。 什么是最好的方式来做到这一点？ 首先，我需要在海洋线程中启动我的服务吗？ 并且如何使它每10分钟从服务器获取更新？ 有些人说handler.postdelayed和一些使用Alarm Manager。 哪一个更好，我们是否有一些例子。 如果更新将在您的应用程序运行时发生，您可以使用Timer，如其他答案中所建议的，或者更新的ScheduledThreadPoolExecutor 。
How do I get a method's execution time? Is there a Timer utility class for things like timing how long a task takes, etc? Most of the searches on Google return results for timers that schedule threads and tasks, which is not what I want. 总有一种老式的方式： long startTime = System.nanoTime(); methodToTime(); long endTime = System.nanoTime(); long duration = (endTime - startTime); //div
我如何获得方法的执行时间？ 是否有定时器实用程序类，用于计时任务需要多长时间等等？ Google上的大多数搜索都会返回定时器的结果，以计划线程和任务，这不是我想要的。 总有一种老式的方式： long startTime = System.nanoTime(); methodToTime(); long endTime = System.nanoTime(); long duration = (endTime - startTime); //divide by 1000000 to get milliseconds. 我用简单的答案去。 适用于我。 long startTime
