Answer 1

我是按照官网上配置的

<plugin>

<groupId>org.mortbay.jetty</groupId>

<artifactId>maven-jetty-plugin</artifactId>

<version>6.1.10</version>

<configuration>

<scanIntervalSeconds>10</scanIntervalSeconds>

<webAppConfig>

<contextPath>/app</contextPath>

<defaultsDescriptor>src/main/resources/webdefault.xml</defaultsDescriptor>

</webAppConfig>

<connectors>

<connector implementation="org.mortbay.jetty.nio.SelectChannelConnector">

<!-- 端口号 -->

<port>8787</port>

<maxIdleTime>500000</maxIdleTime>

</connector>

</connectors>

</configuration>

</plugin>

<defaultsDescriptor>src/main/resources/webdefault.xml</defaultsDescriptor>

这个需要修改jar文件，将true改为false，不然你对html、js、css进行修改时需要重启启动jetty，具体百度

回楼上：我没有用到IDE。我看到你的代码：

<pluginManagement>
  		<plugins>
  			<plugin>
  			<groupId>org.mortbay.jetty</groupId>
  			<artifactId>maven-jetty-plugin</artifactId>
  			<version>6.1.26</version>
  			</plugin>
  		</plugins>
  	</pluginManagement>

并没有对自动扫描热布署配置，请问你的可以自动布署吗？

说明一下：我用的是maven3
