ServletContextListener在Tomcat中的配置问题

在带有监听器的servlet中，执行的顺序是这样的，首先建立servletListerner，然后运行，初始化ServletContext，然后监听ServletContext的变化，最后ServletContext被销毁，加ServletListener的时候不用添加其他的什么配置只在web.xml里面加上监听器就可以了,

servlet可以设置优先级的 
可以把serlet的启动优先级设高一点 
<load-on-startup> 1 </load-on-startup>

<servlet> 
          <servlet-name> proxoolServletConfigurator </servlet-name> 
          <servlet-class> org.logicalcobwebs.proxool.configuration.ServletConfigurator </servlet-class> 
          <init-param> 
              <param-name> xmlFile </param-name> 
              <param-value> WEB-INF/proxool.xml </param-value> 
          </init-param> 
          <load-on-startup> 1 </load-on-startup> 
      </servlet> 
      <servlet> 
        <servlet-name> proxoolAdmin </servlet-name> 
        <servlet-class> org.logicalcobwebs.proxool.admin.servlet.AdminServlet </servlet-class> 
      </servlet> 
      <servlet-mapping> 
        <servlet-name> proxoolAdmin </servlet-name> 
        <url-pattern> /proxooladmin </url-pattern> 
      </servlet-mapping> 
      
      <listener> 
          <listener-class> com.mission.init.SysContextListener </listener-class> 
      </listener>
