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>

<a href="<%=context %>/actions/Course_delete">删除课程</a>
