概觀 overview

AEM Forms可讓您將表單儲存為草稿。草稿功能可讓您維護進行中表單，您可以從任何裝置完成並稍後提交。

依預設，AEM Forms會在 /content/forms/fp 節點。此外，AEM Forms入口網站元件也提供資料服務，供您自訂為草稿和提交儲存使用者資料的實作。例如，您可以將使用者資料儲存在資料存放區中。

必備條件 prerequisites

草稿資料服務 draft-data-service

若要自訂草稿的使用者資料儲存，您必須實作 DraftDataService 介面。下列范常式式碼說明方法和引數。

/**
 * 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 in case of 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;
}

提交資料服務 submission-data-service

若要自訂提交的使用者資料儲存，您必須實作 SubmitDataService 介面。下列范常式式碼說明方法和引數。

/**
 * 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入口網站使用通用唯一識別碼(UUID)概念，為每個草稿和提交的表單產生唯一ID。您也可以產生自己的唯一ID。您可以實作介面FPKeyGeneratorService、覆寫其方法，以及開發自訂邏輯，為每個草稿和提交的表單產生自訂唯一ID。此外，將自訂ID產生實作的服務排名設定為高於0。它可確保使用自訂實作，而非預設實作。

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;
}

您可以使用下列附註來增加使用上述程式碼產生之自訂ID的服務排名：

@Properties(value = { @Property(name = "service.ranking", intValue = 15) } )

若要使用上述附註，請將下列項目匯入您的專案：

import org.apache.felix.scr.annotations.Properties;
 import org.apache.felix.scr.annotations.Property;
