Struts中的多個操作

Question

我目前還不熟悉Java EE，並且剛剛完成了Java EE中的課程。我們被要求創建一個使用MVC Struts 1添加，編輯和刪除的程序。

所以我的問題是，如何做到這一點與多個行動？你有沒有解釋如何使用Struts創建一個成功的Web應用程序的任何教程？

register.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> 

的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> 

Struts的操作在封裝測試：

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");} 
     }
