草稿和提交组件的自定义存储

概述

AEM Forms允许您将表单另存为草稿。 使用草稿功能,您可以维护一个在制品表单,您可以从任何设备稍后完成并提交该表单。
默认情况下,AEM Forms会在发布实例的节点中存储与表单的草稿和提交相关 /content/forms/fp 的用户数据。 此外,AEM Forms门户组件还提供数据服务,您可以使用它自定义为草稿和提交存储用户数据的实施。 例如,您可以将数据存储在数据存储中。

草拟数据服务

要自定义草稿用户数据的存储,您需要实现界面的所有方 DraftDataService 法。 以下示例代码描述了这些方法和参数。
/**
 * 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;
}

提交数据服务

要为提交自定义用户数据存储,您需要实现该界面的所有方 SubmitDataService 法。 以下示例代码描述了这些方法和参数。
/**
 * 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;
}

表单门户使用通用唯一标识符(UUID)概念为每个草稿和提交的表单生成唯一ID。 您还可以生成自己的唯一ID。 您可以实现接口FPKeyGeneratorService,覆盖其方法,并开发自定义逻辑以为每个草稿和提交的表单生成一个自定义唯一ID。 此外,将自定义ID生成实现的服务等级设置为高于0。 它确保使用自定义实现而不是默认实现。
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;
}

您可以使用以下注释来增加使用上述代码生成的自定义ID的服务等级:
@Properties(value = { @Property(name = "service.ranking", intValue = 15) } )
要使用上述注释,请将以下内容导入您的项目:
import org.apache.felix.scr.annotations.Properties;
 import org.apache.felix.scr.annotations.Property;
