之前遇到这个问题，被困扰的不行，终于在学习我们学校大神的代码后明白了，决定发出来，也方便以后自己查看

<servlet>
    <description></description>
    <display-name>ListBookServlet</display-name>
    <servlet-name>ListBookServlet</servlet-name>
    <servlet-class>cn.itcast.chapter05.session.ListBookServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>ListBookServlet</servlet-name>
    <url-pattern>/ListBookServlet</url-pattern>
  </servlet-mapping>
  <servlet>
    <description></description>
    <display-name>PurchaseServlet</display-name>
    <servlet-name>PurchaseServlet</servlet-name>
    <servlet-class>cn.itcast.chapter05.session.PurchaseServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>PurchaseServlet</servlet-name>
    <url-pattern>/PurchaseServlet</url-pattern>
  </servlet-mapping>
  <servlet>
    <description></description>
    <display-name>CartServlet</display-name>
    <servlet-name>CartServlet</servlet-name>
    <servlet-class>cn.itcast.chapter05.session.CartServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>CartServlet</servlet-name>
    <url-pattern>/CartServlet</url-pattern>
  </servlet-mapping>
