maven中jetty热部署

<plugin>                         <groupId> org.mortbay.jetty</groupId >                         <artifactId> maven-jetty-plugin</artifactId >                         <version> 6.1.10</version >                         <configuration>                               <scanIntervalSeconds> 1</scanIntervalSeconds >                                                </configuration>                   </plugin>

重点是这句话：<scanIntervalSeconds> 1</scanIntervalSeconds > 数字1代表间隔1秒检查是否有改动
