微信公众号接口访问凭证access_token获取机制

1：在web,xml中配置servlet

<strong><span style="font-size:18px;"> <servlet>  
        <servlet-name>initServlet</servlet-name>  
        <servlet-class>  
            com.wizincloud.wx.manager.InitServlet  
        </servlet-class>  
        <!-- 配置获取access_token所需参数appid和appsecret -->  
        <init-param>  
            <param-name>appid</param-name>  
            <param-value>wxee1894c6b5a44b8e</param-value>  
        </init-param>  
        <init-param>  
            <param-name>appsecret</param-name>  
            <param-value>7a938414e38c9f007608c40bbb6478fc</param-value>  
        </init-param>  
        <load-on-startup>0</load-on-startup>
