jetty启动项目后js修改后无法保存

在web.xml中加入如下配置即可：

<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.mortbay.jetty.servlet.DefaultServlet</servlet-class>
    <init-param>
            <param-name>useFileMappedBuffer</param-name>
            <param-value>false</param-value>
    <init-param>
    <load-on-startup>0</load-on-startup>
</servlet>
