1、在pom.xml中添加Jetty的插件
<plugin><groupId>org.mortbay.jetty</groupId><artifactId>maven-jetty-plugin</artifactId><version>6.1.5</version><configuration><!-- webdefault.xml中将useFileMappedBuffer设置为false即可在jetty:run的时候不锁定js,css文件 --><webDefaultXml>src/main/resources/jetty/webdefault.xml</webDefaultXml><webAppSourceDirectory>src/main/webapp</webAppSourceDirectory><scanIntervalSeconds>3</scanIntervalSeconds><contextPath>/</contextPath><connectors><connector implementation="org.mortbay.jetty.nio.SelectChannelConnector"><port>8088</port></connector></connectors></configuration></plugin>
2、添加Jetty的配置文件
在/webSocket/src/main/resources/目录中新建jetty目录。
然后新建webdefault.xml文件。
该文件可以在jetty的jar包中找到
需要将webdefault.xml中的useFileMappedBuffer设置为false，这样jetty在运行的过程中就不会锁定静态资源文件了
webdefault.xml文件的内容如下：
<?xml version="1.0" encoding="ISO-8859-1"?><!-- ===================================================================== --><!-- This file contains the default descriptor for web applications. --><!-- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - --><!-- The intent of this descriptor is to include jetty specific or common --><!-- configuration for all webapps.
