Archiviazione personalizzata per il componente Bozze e invii custom-storage-for-drafts-and-submissions-component
Panoramica overview
AEM Forms consente di salvare un modulo come bozza. La funzionalità bozza consente di mantenere un modulo work-in-progress, che puoi completare e inviare successivamente da qualsiasi dispositivo.
Per impostazione predefinita, AEM Forms archivia i dati utente associati alla bozza e all'invio di un modulo nel nodo /content/forms/fp dell'istanza di Publish. Inoltre, i componenti del portale AEM Forms forniscono servizi di dati che è possibile utilizzare per personalizzare l’implementazione della memorizzazione dei dati utente per bozze e invii. Ad esempio, puoi memorizzare i dati utente in un archivio dati.
Prerequisiti prerequisites
Servizio dati bozza draft-data-service
Per personalizzare l'archiviazione dei dati utente per le bozze, è necessario implementare tutti i metodi dell'interfaccia DraftDataService. Nel codice di esempio seguente vengono descritti i metodi e gli argomenti.
/**
* DraftDataService service will get/delete/save user data (attachments and form data) filled with a draft instance of Form
*/
public interface DraftDataService {
/**
* To save/modify user data for this userDataID, it will be null if there is creation
* @param draftDataID: unique identifier associated with the form data
* @param formName: name of the form whose draft is being saved
* @param formData: user data associated with this draft
* @return userdataID corresponding to which user data has been stored and which can be used later to retrieve this user data
* @throws FormsPortalException
*/
public String saveData (String draftDataID, String formName, String formData) throws FormsPortalException;
/**
* Returns the user data stored against the ID passed as the argument
* @param userDataID: unique data id for user data associated with a draft
* @return user data associated with this data ID
* @throws FormsPortalException
*/
public byte[] getData (String userDataID) throws FormsPortalException;
/**
* To delete data associated with this draft
* @param userDataID: unique data id for data associated with a draft
* @return status of delete operation on data associated with this draft
* @throws FormsPortalException
*/
public boolean deleteData (String userDataID) throws FormsPortalException;
/**
* Saves the attachment for current form instance
* @param attachmentsBytes: byte array of the attachment to be saved
* @return unique id (attachmentID) for the attachment just saved (so that it could be retrieved later)
* @throws FormsPortalException
*/
public String saveAttachment (byte[] attachmentBytes) throws FormsPortalException;
/**
* To delete an attachment
* @param attachmentID: unique id for this attachment
* @return status of delete operation performed on attachment corresponding to this attachment ID
* @throws FormsPortalException
*/
public boolean deleteAttachment (String attachmentID) throws FormsPortalException;
/**
* To get attachment bytes
* @param attachmentID: unique id for this attachment
* @return data corresponding to this attachmentID
* @throws FormsPortalException
*/
public byte[] getAttachment (String attachmentID) throws FormsPortalException;
}
Servizio dati di invio submission-data-service
Per personalizzare l'archiviazione dei dati utente per gli invii, è necessario implementare tutti i metodi dell'interfaccia SubmitDataService. Nel codice di esempio seguente vengono descritti i metodi e gli argomenti.
/**
* SubmitDataService service will get/delete/submit user data (attachments and form data) filled with a submission of Form
*/
public interface SubmitDataService {
/**
* Submits the user data passed in argument map
* @param userDataID, unique identifier associated with this user data
* @param formName, name of the form whose draft is being submitted
* @param formData, user data associated with this submission
* @return userdataID, corresponding to which the user data has been stored and which can be used later to retrieve this data
* @throws FormsPortalException
*/
public String saveData (String userDataID, String formName, String formData) throws FormsPortalException;
/**
* Submits the user data provided as byte array
* @param id
* @param data
* @return id corresponding to saved data
* @throws FormsPortalException
*/
public String saveData (String id, byte[] data) throws FormsPortalException;
/** Submits the user data provided as byte array asynchronously for the user name provided in the options map
* @param data data to be saved in bytes
* @param options map containing options that affect this save
* @return id of the saved data instance
*/
public String saveDataAsynchronusly(byte[] data, Map<String, Object> options) throws FormsPortalException;
/**
* Gets the user data stored against the ID passed as argument
* @param userDataID: unique id associated with this user data for this submission
* @return user data associated with this submission
* @throws FormsPortalException
*/
public byte[] getData(String userDataID) throws FormsPortalException;
/**
* Deletes user data stored against the userDataID
* @param userDataID: unique id associated with this user data for this submission
* @return status of the delete operation on this submission
* @throws FormsPortalException
*/
public boolean deleteData(String userDataID) throws FormsPortalException;
/**
* Submits the attachment bytes passed as argument
* @param attachmentsBytes: would expect byte array of the attachment for this submission
* @return attachmentID for the attachment just saved (so that it could be retrieved later)
* @throws FormsPortalException
*/
public String saveAttachment(byte[] attachmentBytes) throws FormsPortalException;
/** Submits the attachment bytes passed as argument asynchronously for the user id provided in options map.
* @param attachmentBytes would expect byte array of the attachment for this submission
* @param options map containing options that affect this save
* @return attachmentID for the attachment just saved (so that it could be retrieved later)
* @throws FormsPortalException
*/
public String saveAttachmentAsynchronously(byte[] attachmentBytes, Map<String, Object> options) throws FormsPortalException;
/**
* To delete an attachment
* @param attachmentID: Unique id for this attachment
* @return status of delete operation performed on attachment corresponding to this attachment ID
* @throws FormsPortalException
*/
public boolean deleteAttachment (String attachmentID) throws FormsPortalException;
/**
* To get attachment bytes
* @param attachmentID: unique id for this attachment
* @return data corresponding to this attachmentID
* @throws FormsPortalException
*/
public byte[] getAttachment (String attachmentID) throws FormsPortalException;

Forms Portal utilizza il concetto di Universally Unique IDentifier (UUID) per generare un ID univoco per ogni bozza e modulo inviato. Puoi anche generare un ID univoco. È possibile implementare l'interfaccia FPKeyGeneratorService, sostituirne i metodi e sviluppare una logica personalizzata per generare un ID univoco personalizzato per ogni bozza e modulo inviato. Inoltre, imposta il rango del servizio dell'implementazione di generazione ID personalizzata su un valore superiore a 0. In questo modo si garantisce che venga utilizzata l’implementazione personalizzata invece di quella predefinita.
public interface FPKeyGeneratorService {
/**
* returns a unique id for draft and submission
*
* @param none
* @return unique id in string format as per the implementation
* @throws FormsPortalException
*/
public String getUniqueId() throws FormsPortalException;
}
Puoi utilizzare l’annotazione seguente per aumentare la classificazione del servizio per l’ID personalizzato generato con il codice precedente:
@Properties(value = { @Property(name = "service.ranking", intValue = 15) } )
Per utilizzare l’annotazione precedente, importa quanto segue nel progetto:
