   使用通配符，将配置量降到最低<fieldset><legend>学生</legend><a href="studentadd">添加学生</a><br><a href="studentdelete">删除学生</a><br></fieldset>不过，一定遵守"约定优于配置"的原则<fieldset><legend>老师</legend>
    <a href="Teacher_add">添加老师</a><br><a href="Teacher_delete">删除老师</a></fieldset>
  </body>

ActionStudent:

package struts.zyl;

import com.opensymphony.xwork2.ActionSupport;

public class ActionStudent extends ActionSupport{
	public String add()
	{
		return SUCCESS;
	}
	public String delete()
	{
		return SUCCESS;
	}
}

ActionTeacher:

package struts.zyl;

import com.opensymphony.xwork2.ActionSupport;

public class ActionTeacher extends ActionSupport{
	public String add()
	{
		return SUCCESS;
	}
	public String delete()
	{
		return SUCCESS;
	}
}

四个JSP:Studentadd_SUCCESS.jsp,Studentdelete_SUCCESS.jsp
