    使用通配符,将配置量降到最低<br />
    <a href="<%=context %>/actions/Studentadd">添加学生</a>
    <a href="<%=context %>/actions/Studentdelete">删除学生</a>
    <br />
    不过,一定要遵守"约定优于配置"的原则
    <br />
    <a href="<%=context %>/actions/Teacher_add">添加老师</a>
    <a href="<%=context %>/actions/Teacher_delete">删除老师</a>
    <a href="<%=context %>/actions/Course_add">添加课程</a>
