<servlet>
    <servlet-name>register</servlet-name>        <!--这里是servlet的名字-->
    <servlet-class>example.RegisterServlet</servlet-class>    <!-- 这里写servlet类在的包路径-->
  </servlet>
  <servlet-mapping>                 <!-- 这里是地址映射-->
    <servlet-name>register</servlet-name><!--这个和上面的同名-->
    <url-pattern>/loginServlet</url-pattern><!--这里写servlet映射地址-->
  </servlet-mapping>
