Question

在我的view.jsp页面中，我从Eclipse中获得了重复的局部变量contact错误。但是，不存在重复变量。当我运行portlet时出现此错误

An error occurred at line: 25 in the jsp file: /html/contact/view.jsp
Type mismatch: cannot convert from com.bcnet.portlet.biobank.model.Contact to com.liferay.portal.model.Contact
22: total="<%= ContactLocalServiceUtil.getContactsCount() %>"
23: />

我使用自己的联系人实体，view.jsp的代码如下

<%@ include file="/html/init.jsp" %>
<%!
   com.liferay.portal.kernel.dao.search.SearchContainer<Contact> searchContainer = null;
%>

<%
    String redirect = PortalUtil.getCurrentURL(renderRequest);
%>

<aui:button-row>
    <portlet:renderURL var="addContactURL">
        <portlet:param name="mvcPath" value="/html/contact/edit_contact.jsp" />
        <portlet:param name="redirect" value="<%= redirect %>" />
    </portlet:renderURL>

    <aui:button onClick="<%= addContactURL.toString() %>" value="add-contact" />
</aui:button-row>

<liferay-ui:search-container emptyResultsMessage="contact-empty-results-message">
    <liferay-ui:search-container-results
        results="<%= ContactLocalServiceUtil.getAllContacts(searchContainer.getStart(), searchContainer.getEnd()) %>"
        total="<%= ContactLocalServiceUtil.getContactsCount() %>"
    />

    <liferay-ui:search-container-row
        className="com.bcnet.portlet.biobank.model.Contact"

    >
        <liferay-ui:search-container-column-text
            name="name"
            value="<%= contact.getFirstName()+\" \"+contact.getLastName() %>"
        />

        <%
            String country = "";

            try {
                country = CountryLocalServiceUtil.getCountry(contact.getCountry()).getName();
            } catch (Exception e) {
            }
        %>

        <liferay-ui:search-container-column-text
            name="country"
            value="<%= country %>"
        />

        <%
            String juristicPersonName = "";

            try {
                juristicPersonName = JuristicPersonLocalServiceUtil.getJuristicPerson
                        (contact.getJuristicPersonId()).getName();
            } 
            catch (Exception e) {
            }
        %>

        <liferay-ui:search-container-column-text

            value="<%= juristicPersonName %>"
        />

        <liferay-ui:search-container-column-text

            property="department"
        />

        <liferay-ui:search-container-column-text
            name="orcId"
            property="orcId"
        />

        <liferay-ui:search-container-column-jsp
            align="right"
            path="/html/contact/contact_actions.jsp"
        />

Answer 1

您似乎有两个进口。并且您正在尝试将liferay Contact对象转换为biobank Contact。删除其中一个导入，然后重试。

Answer 2

对于我的自定义联系人实体，init.jsp中的导入似乎都是正确的。

<%@ page import="com.bcnet.portlet.biobank.model.Contact" %>
<%@ page import="com.bcnet.portlet.biobank.service.ContactLocalServiceUtil"%>

可能是liferay的预定义联系类型com.liferay.portal.model.Contact似乎也在同一范围内导入，这可能导致了问题。因此Type mismatch: cannot convert from com.bcnet.portlet.biobank.model.Contact to com.liferay.portal.model.Contact。

解决方法是为modelVar属性赋予contact以外的biobankContact以外的值<liferay-ui:search-container-row className="com.bcnet.portlet.biobank.model.Contact" keyProperty="contactId" modelVar="contact" escapedModel="<%= true %>" >。所以改变这个

<liferay-ui:search-container-row
        className="com.bcnet.portlet.biobank.model.Contact"
        keyProperty="contactId"
        modelVar="biobankContact" escapedModel="<%= true %>"
    >

以

{{1}}

似乎解决了这个问题。
