  • tomcat——context.xml

    本机tomcat位置:D: omcat7apache-tomcat-7.0.61


    context.xml

    位置:D: omcat7apache-tomcat-7.0.61conf

    每个Web应用程序将加载此文件的内容。

    tomcat服务器会定时去扫描这个文件。一旦发现文件被修改(时间戳改变了),就会自动重新加载这个文件,而不需要重启服务器。

    <?xml version='1.0' encoding='utf-8'?>

    <!-- The contents of this file will be loaded for each web application -->
    <Context>
    
        <!-- Default set of monitored resources -->
        <WatchedResource>WEB-INF/web.xml</WatchedResource>
    
        <!-- Uncomment this to disable session persistence across Tomcat restarts -->
        <!--
        <Manager pathname="" />
        -->
    
        <!-- Uncomment this to enable Comet connection tacking (provides events
             on session expiration as well as webapp lifecycle) -->
        <!--
        <Valve className="org.apache.catalina.valves.CometConnectionManagerValve" />
        -->
    
    </Context>

    <WatchedResource>:指定被监视的资源,此元素可定义多个。如果WEB-INF/web.xml内容改变了,则自动重新加载改应用。


    context.xml的三个作用范围

    1. tomcat server级别:

    在/conf/context.xml里配置

    2. Host级别:

    在/conf/Catalina/${hostName}里添加context.xml,继而进行配置

    3. web app 级别:

    在/conf/Catalina/${hostName}里添加${webAppName}.xml,继而进行配置


    参考文档:
