Datenbank aktualisiert nicht auf Zelle Element geändert

Question

Ich möchte eine Aktualisierungsabfrage auf Zelle bearbeiten. Ich kann vorhandene Zellen bearbeiten, kann sie aber nicht in der Datenbank aktualisieren. Ich kann keine Hibernate-Abfragen für die Zellenbearbeitung erstellen. Bitte helfen Sie mir.

das ist xhtml Datentabelle

<h:form id="view"> 
     <p:growl id="msgs" showDetail="true"/> 
     <p:panel header="View all" > 
      <p:dataTable var="viewall" value="#{UserController.info}" id="viewalldata" editable="true" resizableColumns="true" style="margin-bottom:20px"> 



       <p:ajax event="rowEdit" listener="#{UserController.onRowEdit}" update=":view:msgs" /> 
       <p:ajax event="rowEditCancel" listener="#{UserController.onRowCancel}" update=":view:msgs" />

das ist mein ManagedBean

Dies ist Benutzerklasse

Answer 1

In Ihrem onRowEdit Methode der Einstellung der Parameter wie die followings-

query.setParameter("userName", ((User) event.getObject()).getUserName()); 
query.setParameter("firstName", ((User) event.getObject()).getFirstName()); 

... ändern und so weiter
