struts之lookupDispatchAction的使用
lookupDispatchAction用途之一：当jsp中有多个相同名字的按钮时
jsp:
action:
Struts-config.xml
记得加上
ApplicationResources.properties:
有一点可以看到，地址栏里面没有显示方法名../../my.do隐藏掉了，呵。
jsp:
<body> <html:form action="/my"> age : <html:text property="age"/><html:errors property="age"/><br/> name : <html:text property="name"/><html:errors property="name"/><br/> <input type="submit" name="method" value="save"/> <input type="submit" name="method" value="delete"/> <input type="submit" name="method" value="search"/> </html:form> </body>
action:
public class MyAction extends LookupDispatchAction {
...
public ActionForward saveAction(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
MyForm myForm = (MyForm) form;// TODO Auto-generated method stub
System.out.println("MyAction...save(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)");
return mapping.findForward("succ");
}
public ActionForward deleteAction(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
MyForm myForm = (MyForm) form;// TODO Auto-generated method stub
System.out.println("MyAction...delete(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)");
return mapping.findForward("succ");
}
public ActionForward searchAction(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
MyForm myForm = (MyForm) form;// TODO Auto-generated method stub
System.out.println("MyAction...search(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response)");
return mapping.findForward("succ");
}
/**
* 必须覆盖
*/
protected Map getKeyMethodMap() {
// TODO Auto-generated method stub
/**
* key对应ApplicationResources.properties中=前面
* value对应action中的方法名
*
* ApplicationResources.properties中=后面对应jsp按钮value
*/
Map<String, String> m = new HashMap<String, String>();
m.put("button.save", "saveAction");
m.put("button.delete", "deleteAction");
m.put("button.search", "searchAction");
return m;
}
Struts-config.xml
记得加上
parameter="method"
ApplicationResources.properties:
button.save=save button.delete=delete button.search=search
有一点可以看到，地址栏里面没有显示方法名../../my.do隐藏掉了，呵。
