我知道对此有很多疑问，但是我找不到对我有用的东西。
我从数据库中创建了一个实体类，并为其创建了JPA控制器，最后为该实体创建了一个JSF页面。我通常知道：time_quota。但是我只能手动打开这些页面，一旦运行它们，我将无法对其进行任何操作。但是我只能手动打开这些页面，一旦运行它们，我将无法对其进行任何操作。唯一可行的选项是销毁和编辑用户，即该页面的附件，其余的则不起作用。我无法一页一页地浏览，无法添加用户，看不到所有用户，什么都没有。
这是Create, edit, list, view
Edit.xhtml例如， <h:form>
<h:panelGrid columns="2">
<h:outputLabel value="#{bundle.EditUserLabel_id}" for="id" />
<h:inputText id="id" value="#{userController.selected.id}" title="#{bundle.EditUserTitle_id}" required="true" requiredMessage="#{bundle.EditUserRequiredMessage_id}"/>
<h:outputLabel value="#{bundle.EditUserLabel_firstname}" for="firstname" />
<h:inputText id="firstname" value="#{userController.selected.firstname}" title="#{bundle.EditUserTitle_firstname}" required="true" requiredMessage="#{bundle.EditUserRequiredMessage_firstname}"/>
<h:outputLabel value="#{bundle.EditUserLabel_lastname}" for="lastname" />
<h:inputText id="lastname" value="#{userController.selected.lastname}" title="#{bundle.EditUserTitle_lastname}" required="true" requiredMessage="#{bundle.EditUserRequiredMessage_lastname}"/>
<h:outputLabel value="#{bundle.EditUserLabel_email}" for="email" />
<h:inputText id="email" value="#{userController.selected.email}" title="#{bundle.EditUserTitle_email}" required="true" requiredMessage="#{bundle.EditUserRequiredMessage_email}"/>
<h:outputLabel value="#{bundle.EditUserLabel_password}" for="password" />
<h:inputText id="password" value="#{userController.selected.password}" title="#{bundle.EditUserTitle_password}" required="true" requiredMessage="#{bundle.EditUserRequiredMessage_password}"/>
<h:outputLabel value="#{bundle.EditUserLabel_role}" for="role" />
<h:inputText id="role" value="#{userController.selected.role}" title="#{bundle.EditUserTitle_role}" />
</h:panelGrid>
<h:commandLink action="#{userController.update}" value="#{bundle.EditUserSaveLink}"/>
<br />
<br />
<h:link outcome="View" value="#{bundle.EditUserViewLink}"/>
<br />
<h:commandLink action="#{userController.prepareList}" value="#{bundle.EditUserShowAllLink}" immediate="true"/>
<br />
<br />
<h:link outcome="/index" value="#{bundle.EditUserIndexLink}" />
</h:form>
在其中起作用：
Create.xhtml我正在尝试修复它，现在没有错误了，但是我注意到了一些东西，并且不知道这样做是否有意义，例如，当我打开 <h:form>
<h:panelGrid columns="2">
<h:outputLabel value="#{bundle.CreateUserLabel_id}" for="id" />
<h:inputText id="id" value="#{userController.selected.id}" title="#{bundle.CreateUserTitle_id}" required="true" requiredMessage="#{bundle.CreateUserRequiredMessage_id}"/>
<h:outputLabel value="#{bundle.CreateUserLabel_firstname}" for="firstname" />
<h:inputText id="firstname" value="#{userController.selected.firstname}" title="#{bundle.CreateUserTitle_firstname}" required="true" requiredMessage="#{bundle.CreateUserRequiredMessage_firstname}"/>
<h:outputLabel value="#{bundle.CreateUserLabel_lastname}" for="lastname" />
<h:inputText id="lastname" value="#{userController.selected.lastname}" title="#{bundle.CreateUserTitle_lastname}" required="true" requiredMessage="#{bundle.CreateUserRequiredMessage_lastname}"/>
<h:outputLabel value="#{bundle.CreateUserLabel_email}" for="email" />
<h:inputText id="email" value="#{userController.selected.email}" title="#{bundle.CreateUserTitle_email}" required="true" requiredMessage="#{bundle.CreateUserRequiredMessage_email}"/>
<h:outputLabel value="#{bundle.CreateUserLabel_password}" for="password" />
<h:inputText id="password" value="#{userController.selected.password}" title="#{bundle.CreateUserTitle_password}" required="true" requiredMessage="#{bundle.CreateUserRequiredMessage_password}"/>
<h:outputLabel value="#{bundle.CreateUserLabel_role}" for="role" />
<h:inputText id="role" value="#{userController.selected.role}" title="#{bundle.CreateUserTitle_role}" />
</h:panelGrid>
<br />
<h:commandLink action="#{userController.create}" value="#{bundle.CreateUserSaveLink}" />
<br />
<br />
<h:commandLink action="#{userController.prepareList}" value="#{bundle.CreateUserShowAllLink}" immediate="true"/>
<br />
<br />
<h:link outcome="/index" value="#{bundle.CreateUserIndexLink}"/>
</h:form>
链接为List.xhtml时，但是当我单击例如，在链接末尾的/List.xhtml是＃view
