ssh小问题

[myrl1023]

请各位高手帮看一下这个问题如何解决.谢谢了!!

action是这样写的
/*

* Template path: templates/java/JavaClass.vtl

package com.lovo.struts.action;

public class RegeditAction extends LookupDispatchAction {

private UserBo ubo;

System.out.println(这是删除!!!);

return null;
}
public ActionForward add(ActionMapping mapping, ActionForm form,

// TODO Auto-generated method stub
RegeditForm rForm = (RegeditForm)form;
String name = rForm.getName();

ubo.addUser(upo);


if(!name.equals("")){
int page = 0;
HttpSession session =request.getSession();
return mapping.findForward("success");

}
return mapping.findForward("falide");
}
public ActionForward userList(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {

}

}

protected Map getKeyMethodMap() {
// TODO ?
Map map =new HashMap();
map.put("button.del", "del");
map.put("button.add","add");
map.put("button.userList", "userList");
map.put("button.update","update");
return map;
}
public UserBo getUbo() {
return ubo;
}
public void setUbo(UserBo ubo) {
this.ubo = ubo;
}
}

struts-config.xml关于这部分是这样配的

<form-beans >
<form-bean name="regeditForm" type="com.lovo.struts.form.RegeditForm" />

</form-beans>

<global-exceptions />
<global-forwards />
<action-mappings >
<action
attribute="regeditForm"
name="regeditForm"
parameter="method"
path="/regedit"
scope="request"
type="com.lovo.struts.action.RegeditAction">
<forward name="success" path="/success.jsp" />
<forward name="main" path="/main.jsp" />
<forward name="falide" path="/falide.jsp" />
</action>

</action-mappings>
上面只是一部分代码 只是先做一个测试没有写全.我都测试了的没有问题
问题一、

jsp页面我要这样访问到这个RegeditAction这个类的一个方法(如 del 方法)
<a href="regedit.do?">显示</a>
请问?这后面的参数如何跟啊? 要报这样一个错。。

问题二、
public void delUserPo(UserPo upo){
this.getHibernateTemplate().delete(upo);
}这是传整个对象进行删除,我想按ID进行删除（ssh hibernate交给了spring 管理） 请问怎么办?

为什么这样不的行啊
public void delUserByID(int id){

Session session = this.getSession();
Transaction trans = session.beginTransaction();
String hql="delete from UserPo where id"+id;
session.createQuery(hql);
trans.commit();
session.close();
}
应怎么才能进行ID删除。。。

主要是问题1啊

[upshine86]

老大你的application.resource.资源文件里有你说的
protected Map getKeyMethodMap() {
Map map =new HashMap();
map.put("button.del", "del");
map.put("button.add","add");
map.put("button.userList", "userList");
map.put("button.update","update");
return map;
} ,del ,add,userList ,update 有在资源文件里申明吗?

Action[/regedit] missing resource 'method' in key method map ,错误很明显啊!

[upshine86]

<a href="regedit.do?">显示 </a>
请问?这后面的参数如何跟啊?

你把.do看成.jsp,jsp的url传值!其实可以这样用的!

[fosjos]

regedit.do?method=del&id=...

[upshine86]

public void delUserByID(Integer id){

Session session = getSession();
Transaction trans = session.beginTransaction();
User u= (User)session.get("User.class", id);
session.delete(u);
trans.commit();
session.close();
}

[gongyali2005]

问题1楼上的说了.
问题2:
public void delUserByID(int id){

Session session = this.getSession();
Transaction trans = session.beginTransaction();
String hql="delete from UserPo where id =?";
Query q=session.createQuery(hql);
q.setInteger(0,id);
session.execute();
trans.commit();
session.close();
}

[zjsbruce]

什么跟什么哦，问题二太明显：String hql="delete from UserPo where id"+id; 明显红色那里少了个‘=’号，问题1 也是太明显：<a href="regedit.do?">显示 </a>。‘？’后面要带上你要执行的方法啊，传个参数过去,比如你要让Action执行add,就应该是：<a href="regedit.do?method=add">你这个参数的名称必须是method因为在你xml文件里面配了这一个属性<action
attribute="regeditForm"
name="regeditForm"
parameter="method"
path="/regedit"
scope="request"
type="com.lovo.struts.action.RegeditAction">
<forward name="success" path="/success.jsp" />
<forward name="main" path="/main.jsp" />
<forward name="falide" path="/falide.jsp" />
</action>
红色的就是属性名称。

就是用<a href="regedit.do?">显示 </a>去访问,别的都没有什么问题,就是如何写这一个URL 不要乱去找别的地方错,别的地方没有错误....

[「已注销」]

楼上的朋友你说的这个是DispacthAction
我问的是他的子类LookupDispacthAction
<a href="regedit.do?">显示 </a>去访问,别的都没有什么问题,就是如何写这一个URL

[「已注销」]

我晓得你说的那是他的父类型DispatchAction嘛
我是说lookupDispacthAction 的
URL如何跟啊.

[yojiwei]

1、regedit.do?method=del
2、用QBC删除

DetachedCriteria de = DetachedCriteria.forClass(TbAccess.class);
de.add(Restrictions.eq("ID", tbac.getId()));
((IAccessDao)getService("AccessDao")).del_Object(de);
