在使用其他自定义portlet调用一个add函数时，再次遇到同样问题。 我在我的portlet类中有一个使用addrestaurant（餐厅）的方法，当我从我的视图中调用它来添加数据时，它会给我以下错误。
05:27:42,752 ERROR [http-bio-8080-exec-4][render_portlet_jsp:154] java.lang.NoSuchMethodException: com.liferay.util.bridges.mvc.MVCPortlet.addrestaurant(javax.portlet.ActionRequest, javax.portlet.ActionResponse)

我检查了所有的东西，但仍然没有理由我发现为什么会发生这种情况..当我创建新的portlet时，每次都知道它...
以下是我的restaurantportlet.java类
public class RestaurantPortlet extends MVCPortlet {
private static Log log = LogFactory.getLog(RestaurantPortlet.class);
private static String errorJSP="/jsps/error.jsp" ;

log.info("Inside addRegistration");
List<String> errors=new ArrayList<String>();
restaurant rest=RestaurantActionUtil.getRestaurantFromRequest(request);
boolean bookValid=RestaurantValidator.validateRestaurant(rest,errors);
if(bookValid) {
try {
log.info(rest);
restaurant test=restaurantLocalServiceUtil.addrestaurant(rest);
if(test==null) {
log.error("Restaurant was Found Null");
response.setRenderParameter("jspPage", errorJSP);
return ;
}
} catch (SystemException e) {
log.error(e);
/*If there is an error then divert the control to the error page.*/
response.setRenderParameter("jspPage", errorJSP);
return ;
}
SessionMessages.add(request,"restaurant-added");
return ;
}
else {
for (String error : errors) {
SessionErrors.add(request, error);
}
SessionErrors.add(request, "error-while-adding");
request.setAttribute("rest",rest);
return ;

}
以下是我的restaurantImpl.java类

以下是我的restuarntActionutil类
public class RestaurantActionUtil {
public static restaurant getRestaurantFromRequest(ActionRequest request) {
ThemeDisplay themeDisplay = (ThemeDisplay) request
.getAttribute(WebKeys.THEME_DISPLAY);

rest.setModifieddate(Calendar.getInstance().getTime());
rest.setLastmodifiedby(themeDisplay.getUserId());
rest.setRestregId((ParamUtil.getLong(request, "licensekey")));
rest.setIsdeleted(false);
return rest;
}
}
以下是我的view.jsp代码，从中调用此方法。
<liferay-portlet:actionURL name="addrestaurant" var="addrestoURL"></liferay-portlet:actionURL>
<form class="form_validation_ttip" action="<%= addrestoURL.toString()%>" method="post">
这是我的按钮形式。
<button class="btn" name="btnback" >Save</button>
答案 0 :(得分：0)
你能把portlet.xml放在这里吗？
看起来你没有指定你的类，所以Liferay试图使用默认的MVCPortlet类。当然，没有addrestaurant()方法。
这不是代码问题，而是配置问题。
