model-view-controller - Struts 中的多个动作

Question

我目前是 Java EE 的新手，我刚刚完成了 Java EE 课程。我们被要求使用 MVC Struts 1 创建一个具有添加、编辑和删除功能的程序。

所以我的问题是，如何通过多个动作来做到这一点？您是否有任何教程解释了如何使用 Struts 创建成功的 Web 应用程序？

注册.jsp

    <form name="myform">
    // other inputs going here
    <input type="button" name="add" value="add" id="add" onclick="submitAction(this)">
    <input type="button" name="update" value="update" id="update" onclick="submitAction(this)">
    <input type="button" name="delete" value="delete" id="delete" onclick="submitAction(this)">
    </form>

javascript:

function submitAction(actType)
{
document.myform.action = actType.id;
document.myform.submit();

}

<action name="MyUpdateAction" type="test.MyUpdateAction" path="/update" input="/register.jsp">
  <forward name="success" path="/updated.jsp" />
  <forward name="failure" path="/failure.jsp" />
</action>
<action name="MyAddAction" tepe="test.MyAddAction" path="/add" input="/register.jsp">
  <forward name="success" path="/added.jsp" />
  <forward name="failure" path="/failure.jsp" />
</action>
<action name="MyDeleteAction" type="test.MyDeleteAction" path="/delete" input="/register.jsp">
  <forward name="success" path="/deleted.jsp" />
  <forward name="failure" path="/failure.jsp" />
</action>

包测试中的 Struts 操作：

 public class MyUpdateAction extends org.apache.struts.action.Action {
    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception 
    {       //do update Stuff...
        if () {
            return mapping.findForward("success");
        } else {
                return mapping.findForward("failure");}
    }

    public class MyAddAction extends org.apache.struts.action.Action {
    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception 
        {           //do add Stuff...       
        if () {
            return mapping.findForward("success");
        } else {
                return mapping.findForward("failure");}
        }

    public class MyDeleteAction extends org.apache.struts.action.Action {
    public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception 
        {       //do delete Stuff...    
        if () {
            return mapping.findForward("success");
        } else {
                return mapping.findForward("failure");}
        }
