web.xml文件中修改servlet直接访问jsp文件

   <servlet>
    <servlet-name>delete</servlet-name>
    <jsp-file>/WEB-INF/JspView/deleteBookInfo.jsp</jsp-file>
  </servlet>

  <servlet-mapping>
    <servlet-name>delete</servlet-name>
    <url-pattern>/delete</url-pattern>
  </servlet-mapping> 

设定servlet名字为delete，转到WebRoot下的deleteBookInfo.jsp页面
