In this tutorial, we will following the guideline of developing a plugin to develop our Form Submission Statistics Generator. Please also refer to the very first tutorial 如何开发一个Bean Shell Hash Variable插件 for more details steps.
1. What is the problem?
We have 2 SQL Chart menus (the queries used are dependent on MySQL) to show form data submission statistics and this 2 menus always need to replicate for different form.
2. What is your idea to solve the problem?
We can develop a Generator 插件 to ease the process to replicate the 2 SQL Chart menus for other forms.
3. What is the input needed for your plugin?
To develop a Generator Plugin for our 2 SQL Chart menus, we can consider to provide the following as input.
- Userview ID : Which userview to add this 2 SQL menus
- Some option for label change in Category label, Menu label, and Chart label
4. What is the output and expected outcome of your plugin?
2 SQL Chart menus will be added to the selected userview under a new category. One of the menu will show the monthly submission chart and another one will show the daily submission chart based on the year and month filter.
5. Is there any resources/API that can be reuse?
First, we can do build our 2 SQL Chart menus in one of the existing userview. Then, copy the JSON definition of the category which contains our 2 SQL Chart menus form the "ADVANCED: JSON Definition" on the bottom of the Userview Builder.
在本教程中，我们将遵循开发插件的 指导方针 来开发我们的表单提交统计信息生成器。 有关更多详细信息步骤，请参阅第一个教程 如何开发一个Bean Shell哈希变量插件。
1.什么问题？
我们有2个SQL Chart菜单（使用的查询依赖于MySQL）来显示表单数据提交统计信息，这2个菜单总是需要复制不同的表单。
2.你有什么想法来解决这个问题？
我们可以开发一个 Generator插件 来简化这个过程，为其他表单复制2个SQL Chart菜单。
3.你的插件需要什么输入？
要为我们的2个SQL图表菜单开发Generator插件，我们可以考虑提供以下内容作为输入。
- Userview ID：哪个用户视图添加这2个SQL菜单
- “类别”标签，“菜单”标签和“图表”标签中的一些标签更改选项
4.你的插件的输出和预期结果是什么？
2 SQL Chart菜单将被添加到选定的用户视图下一个新的类别。其中一个菜单将显示每月提交图表，另一个将显示基于年份和月份过滤器的每日提交图表。
5.有没有可重用的资源/ API？
首先，我们可以在现有的用户视图之一中构建我们的2个SQL图表菜单。然后，将包含我们的2个SQL Chart菜单的类别的JSON定义复制到Userview Builder的底部的“ADVANCED：JSON Definition” 。
我们将得到我们的类别的JSON定义如下。请注意在2个SQL图表菜单中使用的查询依赖于MySQL数据库。We will get our JSON definition of the category as following. Please note that the queries used in the 2 SQL Chart menus are dependent on MySQL database.

} |
After that, we can utilize the GeneratorUtil to add the category JSON definition to our selected userview JSON definition.
6. Prepare your development environment
之后，我们可以利用 GeneratorUtil 将类别JSON定义添加到我们选择的userview JSON定义中。
6. 准备你的开发环境
我们需要始终准备好Joget Workflow Source Code，并按照这个指导方针建立起来 。
本教程的以下内容是使用Macbook Pro和Joget源代码5.0.0版编写的。 其他平台命令请参考 如何开发插件。
让我们说我们的文件夹目录如下。
We need to always have our Joget Workflow Source Code ready and builded by following this guideline.
The following of this tutorial is prepared with a Macbook Pro and Joget Source Code version 5.0.0. Please refer to 如何开发插件 for other platform command.
Let said our folder directory as following.
| Code Block |
|---|
- Home
- joget
- plugins
- jw-community
-5.0.0 |
The "plugins" directory is the folder we will create and store all our plugins and the "jw-community" directory is where the Joget Workflow Source code stored.
“plugins”目录是我们要创建和存储我们所有插件的文件夹，“jw-community”目录是Joget Workflow源代码存储的地方。
运行以下命令在“plugins”目录下创建一个maven项目。Run the following command to create a maven project in "plugins" directory.
| Code Block | ||
|---|---|---|
| ||
cd joget/plugins/ ~/joget/jw-community/5.0.0/wflow-plugin-archetype/create-plugin.sh org.joget.tutorial form_submission_statistics_generator 5.0.0 form_submission_statistics_generator 5.0.0 |
然后，shell脚本将要求我们为您的插件输入一个版本，并在生成maven项目之前要求我们确认。Then, the shell script will ask us to key in a version for your plugin and ask us for confirmation before generate the maven project.
| Code Block | ||
|---|---|---|
| ||
Define value for property 'version': 1.0-SNAPSHOT: : 5.0.0 [INFO] Using property: package = org.joget.tutorial Confirm properties configuration: groupId: org.joget.tutorial artifactId: form_submission_statistics_generator version: 5.0.0 package: org.joget.tutorial Y: : y |
We should get "BUILD SUCCESS" message shown in our terminal and a "form我们应该在终端上显示“BUILD SUCCESS”消息，在“plugins”文件夹中创建一个“form_submission_statistics_generator" folder created in "plugins" folder.generator”文件夹。
用你喜欢的IDE打开maven项目。我将使用 NetBeans。 Open the maven project with your favour IDE. I will be using NetBeans.
7. Just code it!
a. Extending the abstract class of a plugin type
Create a "FormSubmissionStatisticsGenerator" class under "org在“org.joget.tutorial" package. Then, extend the class with tutorial”包下创建一个“FormSubmissionStatisticsGenerator”类。然后，使用org.joget.apps.generator.model.GeneratorPlugin abstract class. Please refer to Generator 插件. 抽象类来扩展 该类。请参考 Generator插件。
b. Implement all the abstract
...
methods
像往常一样，我们必须执行所有的抽象方法。我们将使用AppPluginUtil.getMessage方法来支持i18n，并使用常量变量MESSAGE_PATH作为消息资源包目录As usual, we have to implement all the abstract methods. We will using AppPluginUtil.getMessage method to support i18n and using constant variable MESSAGE_PATH for message resource bundle directory.
| Code Block | ||||||
|---|---|---|---|---|---|---|
| ||||||
package org.joget.tutorial;
import org.joget.apps.app.service.AppPluginUtil;
import org.joget.apps.app.service.AppUtil;
import org.joget.apps.generator.model.GeneratorPlugin;
import org.joget.apps.generator.model.GeneratorResult;
public class FormSubmissionStatisticsGenerator extends GeneratorPlugin {
private final static String MESSAGE_PATH = "messages/FormSubmissionStatisticsGenerator";
public String getName() {
return "File Link Datalist Formatter";
}
public String getVersion() {
return "5.0.0";
}
public String getClassName() {
return getClass().getName();
}
public String getLabel() {
//support i18n
return AppPluginUtil.getMessage("org.joget.tutorial.FormSubmissionStatisticsGenerator.pluginLabel", getClassName(), MESSAGE_PATH);
}
public String getDescription() {
//support i18n
return AppPluginUtil.getMessage("org.joget.tutorial.FormSubmissionStatisticsGenerator.pluginDesc", getClassName(), MESSAGE_PATH);
}
public String getPropertyOptions() {
return AppUtil.readPluginResource(getClassName(), "/properties/formSubmissionStatisticsGenerator.json", null, true, MESSAGE_PATH);
}
@Override
public String getExplanation() {
//support i18n
return AppPluginUtil.getMessage("generator.formSubmissionStatistics.explanation", getClassName(), MESSAGE_PATH);
}
@Override
public GeneratorResult generate() {
throw new UnsupportedOperationException("Not supported yet.");
}
} |
Then, we have to do a UI for admin user to provide inputs for our plugin. In getPropertyOptions method, we already specify our 插件属性选项与配置 definition file is locate at "/properties/formSubmissionStatisticsGenerator.json". Let us create a directory "resources/properties" under "form_submission_statistics_generator/src/main" directory. After create the directory, create a file named "formSubmissionStatisticsGenerator.json" in the "properties" folder.
然后，我们必须为管理员用户提供一个UI来为我们的插件提供输入。在getPropertyOptions方法中，我们已经指定了我们的 插件属性选项和配置 定义文件位于“/properties/formSubmissionStatisticsGenerator.json”。让我们在“form_submission_statistics_generator / src / main”目录下创建一个目录“resources / properties”。创建目录后，在“properties”文件夹中创建一个名为“formSubmissionStatisticsGenerator.json”的文件。
在属性定义选项文件中，我们需要提供如下的选项。请注意，我们可以在我们的属性选项中使用“@@ message.key @@”语法来支持i18n。In the properties definition options file, we will need to provide options as below. Please note that we can use "@@message.key@@" syntax to support i18n in our properties options.

In the getCategoryJson method, we will retrieve the category JSON definition form "在getCategoryJson方法中，我们将检索类别JSON定义形式“/resources/category.json" file. Let us create a directory "resources/resources" under "formjson”文件。让我们在“form_submission_statistics_generator / src / main”目录下创建一个目录“resources / main" directory. After create the directory, create a file named "category.json" in the "resources" folder. Then, copy the category JSON definition we created previously and paste it inside this file. We will need to replace some of the hardcoded value as variable and remember to escape those existing "%" to "%%" as the AppUtil.readPluginResource using String.format for injects value into the file.resources”。创建目录后，在“resources”文件夹中创建一个名为“category.json”的文件。然后，复制我们之前创建的类别JSON定义，并将其粘贴到此文件中。我们将需要将一些硬编码值替换为变量，并记住将使用String.format的AppUtil.readPluginResource转义为将现有的“％”转义为“%%”，以便将值注入到文件中。

c. Manage the dependency libraries of your plugin
Our plugin is using javax我们的插件使用javax.servlet.http.HttpServletRequest and javaxHttpServletRequest和javax.servlet.http.HttpServletResponse class, so we will need to add jsp-api library to our POM file.HttpServletResponse类，因此我们需要将jsp-api库添加到我们的POM文件中。
| Code Block | ||
|---|---|---|
| ||
<!-- Change plugin specific dependencies here -->
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>jsp-api</artifactId>
<version>2.0</version>
</dependency>
<!-- End change plugin specific dependencies here --> |
d. Make your plugin internationalization (i18n) ready
We are using i18n message key in getLabel and getDescription method. We also used i18n message key in our properties options definition as well. So, we will need to create a message resource bundle properties file for our plugin.
我们在getLabel和getDescription方法中使用i18n消息密钥。我们还在我们的属性选项定义中使用了i18n消息密钥。所以，我们需要为我们的插件创建一个消息资源包属性文件。
在“formCreate directory "resources/messages" under "form_submission_statistics_generator / src / main" directory. Then, create a "FormSubmissionStatisticsGenerator.properties" file in the folder. In the properties file, let add all the message keys and its label as below.main”目录下创建目录“resources / messages”。然后，在该文件夹中创建一个“FormSubmissionStatisticsGenerator.properties”文件。在属性文件中，让我们添加所有的消息键和它的标签如下。

e. Register your plugin to Felix Framework
We will have to register our plugin class in Activator class (Auto generated in the same class package) to tell Felix Framework that this is a plugin.我们将不得不在Activator类（在同一个类包中自动生成）中注册我们的插件类，以告诉Felix框架这是一个插件。
| Code Block | ||
|---|---|---|

public void start(BundleContext context) {
registrationList = new ArrayList<ServiceRegistration>();
//Register plugin here
registrationList.add(context.registerService(FormSubmissionStatisticsGenerator.class.getName(), new FormSubmissionStatisticsGenerator(), null));
} |
f. Build it and testing
Let build our plugin. Once the building process is done, we will found a "form让我们建立我们的插件。一旦构建过程完成，我们将在“form_submission_statistics_generator -5.0.0.jar" file is created under "form/ target”目录下创建一个“form_submission_statistics_generator/target" directory.
Then, let upload the plugin jar to Manage Plugins. After upload the jar file, double check the plugin is uploaded and activated correctly.
Now, we can open one for our form in Form Builder for testing the generator. Click on the "Generate App" button on right top of the Form Builder. Please refer to Generate App.
Let us check the properties page for "Advanced Generator".
After the generation process is done.
A new category is added to our userview.
-5.0.0.jar”文件。
然后，让插件jar上传到 管理插件。上传jar文件后，仔细检查插件是否正确上传和激活。
现在，我们可以在Form Builder中为我们的表单打开一个测试生成器。点击Form Builder右上方的“Generate App”按钮。请参阅 生成应用程序。
让我们检查“高级生成器”的属性页面。
生成过程完成后。
一个新的类别被添加到我们的用户视图。
SQL图表菜单将显示如下。The SQL chart menus will shown as following.
