jsf - 如何使用 Hibernate 和 Spring 将动态 JSF 表单保存到数据库中

Question

我们正在使用 JSF Primefaces 3.2。我有一个模块，用户将在其中使用自己的选择创建一些动态字段，例如文本字段、文本区域、选择框、复选框、单选按钮，然后将根据这些选定字段生成表单。我已经成功创建了用户创建表单并根据他的选择生成表单的第一部分。但现在我面临的问题是如何将此表单保存到数据库中。在这里我附上我的模块的一些代码，以便您轻松理解并快速找到解决方案。

这是我使用动态生成所有字段的 JSF 表单

    <h:form id="formObjectiveLibrary">
    <h:panelGrid columns="3" styleClass="form-table" columnClasses="column_1, column_2, column_3">

        <p:selectOneListbox id="objectiveTemplateID" value="#{objectiveTemplateAction.objectiveTemplateID}" style="height: 120px; width: 200px">
        <f:selectItems value="#{objectiveTemplateAction.objectiveTemplateList}" var="template" itemLabel="#{template.title}" itemValue="#{template.id}"></f:selectItems>
        <p:ajax event="change" listener="#{objectiveTemplateAction.loadTemplateQuestionsByID()}" update="libraryQuestionContainer"/>
        </p:selectOneListbox>
        <p:message for="objectiveTemplateID"/>
    </h:panelGrid>
