Quartz + Spring双执行

Question

我有Quartz 2.2.1和Spring 3.2.8 app。我的问题是，在启动过程中，Quartz在2秒后创建了两个以下的作业。我的工作必须每10秒执行一次，但它会执行两次：

Info:   INFO: Starting TASK on Mon Apr 20 16:22:21 CEST 2015
Info:   INFO: Starting TASK on Mon Apr 20 16:22:23 CEST 2015
Info:   INFO: Starting TASK on Mon Apr 20 16:22:31 CEST 2015
Info:   INFO: Starting TASK on Mon Apr 20 16:22:33 CEST 2015
Info:   INFO: Starting TASK on Mon Apr 20 16:22:41 CEST 2015
Info:   INFO: Starting TASK on Mon Apr 20 16:22:43 CEST 2015

我尝试按照Quartz + Spring double execution on startup上的建议。提供的答案（在web.xml中删除包含“ContextLoaderListener”的标签）没有帮助，因为我遇到了WebContext丢失的错误。谢谢你的帮助。

这是我的web.xml：

我的spring-servlet.xml看起来像这样：
