Jsf 单元格编辑控件中的primefaces不更新数据库中的数据

我假设您已经在环境中配置了hibernate，并将数据库映射到实体类。您可以相应地更新记录

您可以访问行并更新记录，如：

<h:form id="dtform">
    <p:growl showDetail="true" id="mess"/>
    <p:dataTable id="dt1" scrollable="true" scrollWidth="700" var="mas"  value="#{viewtable.dlist}" editable="true">
        <f:facet name="header">
            Edit Here
        </f:facet>
        <p:column headerText="Regno" width="100">
            <p:cellEditor>
                <f:facet name="output">
                    <h:outputText  value="#{mas.regno}"/>
                </f:facet>
                <f:facet name="input">
                    <p:inputText value="#{mas.regno}"/>

你能更改方法的名称吗？在java中，“get”似乎是一种保留字。我试过了，但仍然有问题。。。。。。。请给我一个示例代码，说明如何将hibernate与primefaces DataTable集成您的方法有效吗？据我所知，您的代码与单元内编辑完全不同。首先，要进行数据库选择。你能发布你的prime facestags吗？兄弟，我发布了我的设计部分，但在过去的一周里我一直面临这个问题。请给出一些想法。你的编辑方法是托管bean中的onEdit（）。但是，您尝试使用get（）方法更新数据。是否要将hibernate用于此操作？看看这个
