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:
<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>
public class MyAction extends LookupDispatchAction {...public ActionForward saveAction(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) {MyForm myForm = (MyForm) form;// TODO Auto-generated method stubSystem.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 stubSystem.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 stubSystem.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;}parameter="method"
button.save=savebutton.delete=deletebutton.search=search
