jsp - 添加数据时 Liferay Portlet 中的 NoSuchMethodException

Question

我正在使用liferay，并且我创建了自己的portlet，它刚刚添加了功能。但是我在添加书籍时遇到了一些错误

这是我的 view.jsp

<%@ include file="/init.jsp"%>


<%
    Restaurant resto = (Restaurant) request.getAttribute("Restaurant");
    if (resto == null) {
        resto = new RestaurantImpl();

        resto.setTable_Count(1);
    }
%>
<liferay-portlet:actionURL name="addreRestaurant" var="addreRestaurantURL"></liferay-portlet:actionURL>

<aui:form action="<%=addreRestaurantURL.toString() %>" method="post" name="fm">

    <aui:fieldset>
        <%-- <liferay-ui:error key="title-required" message="title-required" /> --%>

在出现错误之后，我面临着它无法找到 addreRestaurant 方法的问题，但我有那个方法。那么我在哪里做错了？

错误如下：

您的方法：public Restaurant addreRestaurant(Restaurant restoParam)
portlet 所需的方法：addreRestaurant(javax.portlet.ActionRequest,javax.portlet.ActionResponse)

score 1 · Accepted Answer

您的 mvc 类方法名称是addRestaurant ()，而您的 jsp 需要：

名称=“地址餐厅”

方法名称不同:)

score 1 · Accepted Answer

您的新堆栈跟踪与另一个错误有关。问题出在 RestauranteServiceImpl.addreRestaurant() 内部，更具体地说是代码段：

resourceLocalService.addResources(restoParam.getCompanyId(),
                    restoParam.getGroupId(), restoParam.getUserId(),
                    Restaurant.class.getName(), restoParam.getPrimaryKey(),false,
                    true, true);

这意味着您没有与您的类或 portlet 相关的资源操作。您是否定义了资源操作映射？

score 1 · Accepted Answer

我终于把事情做好了……在数据库中，在 actionresources 表中没有关于我的 addRestaurant 操作的条目。

经过大量的研发发现......我必须在该表中手动添加 addRestaurant 条目，它就可以工作。

我现在将搜索它如何不自动将条目添加到资源操作。
