Activiti6快速入门指南

發(fā)布時(shí)間：2023/12/20 编程问答 51 豆豆

生活随笔收集整理的這篇文章主要介紹了 Activiti6快速入门指南小編覺(jué)得挺不錯(cuò)的,現(xiàn)在分享給大家,幫大家做個(gè)參考.

Activiti6快速入門(mén)指南

這個(gè)快速入門(mén)假定：

熟悉Maven和Java
使用Java的開(kāi)發(fā)環(huán)境

本教程將引用以下變量

變量	描述
$mvnProject	maven項(xiàng)目的根位置
$actUnzipedPack	從http://www.activiti.org/download.html下載的解壓縮文件的根位置。
$quickStartJavaProjectName	Quick Start Java Project的名稱(chēng)。建議將其作為“ActivitiDeveloperQuickStart”。
...	為簡(jiǎn)潔起見(jiàn)，請(qǐng)參閱跳過(guò)的信息。
$actVer	Activiti的版本目前正在運(yùn)行。

1.簡(jiǎn)介

本快速入門(mén)顯示了使用Activiti將業(yè)務(wù)流程管理（BPM）嵌入到您的應(yīng)用程序中的簡(jiǎn)單性。您將構(gòu)建一個(gè)命令行應(yīng)用程序，將基于標(biāo)準(zhǔn)的業(yè)務(wù)流程建模表示法（BPMN）邏輯嵌入到您的應(yīng)用程序中。

Activiti擁有先進(jìn)的流程設(shè)計(jì)工具，可將更復(fù)雜的BPM邏輯嵌入到您的應(yīng)用程序中。這些工具包括基于Eclipse和基于Web的BPMN編輯器，僅舉幾例。為簡(jiǎn)潔起見(jiàn)，本快速入門(mén)僅使用Activiti的Java API。

有關(guān)其他Activiti BPM工具的介紹，請(qǐng)參閱：

樣品入門(mén)快速入門(mén)
Activiti用戶指南

本快速入門(mén)

一般來(lái)說(shuō)，遠(yuǎn)離特定于IDE的插圖（盡管它們是謹(jǐn)慎地完成的）。Activiti適用于任何Java友好的IDE。
使用Maven，但Gradle和Ivy等其他構(gòu)建和依賴管理系統(tǒng)也可以工作。

2.創(chuàng)建和設(shè)置Maven項(xiàng)目

$quickStartJavaProjectName使用以下Maven依賴項(xiàng)創(chuàng)建名為“ActivitiDeveloperQuickStart”（以下稱(chēng)為）的Java項(xiàng)目：

文件：$ mvnProject /pom.xml

? <modelVersion>4.0.0</modelVersion>

? <groupId>$quickStartJavaProjectName</groupId>

? <artifactId>$quickStartJavaProjectName</artifactId>

? <version>0.0.1-SNAPSHOT</version>

?

? <dependencies>

??? <dependency>

????? <groupId>org.activiti</groupId>

????? <artifactId>activiti-engine</artifactId>

????? <version>$actVer</version>

??? </dependency>

??? <dependency>

????? <groupId>org.slf4j</groupId>

????? <artifactId>slf4j-api</artifactId>

????? <version>1.7.21</version>

??? </dependency>

??? <dependency>

????? <groupId>org.slf4j</groupId>

????? <artifactId>slf4j-log4j12</artifactId>

????? <version>1.7.21</version>

??? </dependency>

??? <dependency>

????? <groupId>com.h2database</groupId>

????? <artifactId>h2</artifactId>

????? <version>1.4.193</version>

? ??</dependency>

? </dependencies>

</project>

當(dāng)然，$actVer將替換為下載的Activiti版本。例如，如果您下載的Activiti軟件包是“activiti-6.0.0”，那么它的值$actVer將是6.0.0。

請(qǐng)注意以下依賴項(xiàng)：

Activiti（org.activiti） - Activiti的BPM引擎
數(shù)據(jù)庫(kù)（com.h2database） - H2數(shù)據(jù)庫(kù)
記錄（org.slf4j） - Java的簡(jiǎn)單日志外觀

在引用構(gòu)建目錄時(shí)，本教程假定您的maven項(xiàng)目的標(biāo)準(zhǔn)Maven構(gòu)建路徑：

路徑	描述
$mvnProject/ SRC /主/ JAVA	Java源目錄
$mvnProject/ src目錄/主/資源	資源目錄
$mvnProject/ SRC /測(cè)試/ JAVA	Java測(cè)試目錄
$mvnProject/ SRC /測(cè)試/資源	資源測(cè)試目錄

您應(yīng)該能夠構(gòu)建空白項(xiàng)目。在繼續(xù)之前，請(qǐng)確保整體狀態(tài)為“BUILD SUCCESS”。

命令：mvn compile

基本路徑：$ mvnProject

?筆記：

您的輸出可能看起來(lái)不同。最值得注意的是，maven可能需要檢索項(xiàng)目依賴項(xiàng)。

3.創(chuàng)建流程引擎

正如之前在maven依賴關(guān)系摘要中所建議的那樣，Activiti利用Simple Logging Facade for Java（slf4j）進(jìn)行日志記錄。在此示例應(yīng)用程序中，我們將使用log4j日志記錄實(shí)現(xiàn)。將log4j.properties文件添加到項(xiàng)目中。

文件：$ mvnProject /src / main / resources / log4j.properties

log4j.rootLogger=DEBUG, ACT

log4j.appender.ACT=org.apache.log4j.ConsoleAppender

log4j.appender.ACT.layout=org.apache.log4j.PatternLayout

log4j.appender.ACT.layout.ConversionPattern=%d{hh:mm:ss,SSS} [%t] %-5p %c %x - %m%n

使用空白main創(chuàng)建一個(gè)新的Java類(lèi)。

文件：$ mvnProject /src / main / java / com / example / OnboardingRequest.java

package com.example;

publicclassOnboardingRequest {

?publicstaticvoidmain(String[] args) {

???

}

添加到主要入口點(diǎn)是創(chuàng)建Process Engine。添加到OnboardingRequest.java，如下圖所示：

添加到主要入口點(diǎn)是創(chuàng)建Process Engine。添加到OnboardingRequest.java，如下圖所示：

package com.example;

importorg.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration;

publicclassOnboardingRequest {

?publicstaticvoidmain(String[] args) {

???ProcessEngineConfiguration cfg = newStandaloneProcessEngineConfiguration()

?????.setJdbcUrl("jdbc:h2:mem:activiti;DB_CLOSE_DELAY=1000")

?????.setJdbcUsername("sa")

?????.setJdbcPassword("")

?????.setJdbcDriver("org.h2.Driver")

?????.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);

???ProcessEngine processEngine = cfg.buildProcessEngine();

???String pName = processEngine.getName();

???String ver = ProcessEngine.VERSION;

???System.out.println("ProcessEngine[" + pName + "]Version: [" + ver + "]");

}

文件：$ mvnProject /src / main / java / com / example / OnboardingRequest.java

添加行	說(shuō)明
3-4	Activiti流程引擎和配置。
5,9	獨(dú)立環(huán)境的配置幫助程序（例如，不使用依賴項(xiàng)管理器）。
9-15	使用基于內(nèi)存的h2嵌入式數(shù)據(jù)庫(kù)創(chuàng)建Process Engine。
16-18	顯示Process Engine配置和Activiti版本。

Activiti支持依賴注入

Activiti是專(zhuān)為并且可以輕松利用依賴注入而構(gòu)建的。有關(guān)詳細(xì)信息，請(qǐng)查看Activiti用戶指南。

Activiti與許多數(shù)據(jù)庫(kù)提供商合作

“?$actUnzipedPack/ database / create”中的數(shù)據(jù)庫(kù)腳本

支持IDE和平臺(tái)獨(dú)立以及此快速入門(mén)的簡(jiǎn)單性，添加“胖罐”配置，如下面第1-28行到pom.xml中所示。

文件：$ mvnProject /pom.xml

筆記：

感興趣的關(guān)鍵輸出是打印您的Activiti版本：$actVer?它應(yīng)該與配置的版本匹配
“[INFO]構(gòu)建jar：$mvnProject / target /?$quickStartJavaProjectName-0.0.1-SNAPSHOT-jar-with-dependencies.jar”

或者，當(dāng)然，您可以在IDE中運(yùn)行相同的程序。例如，在Eclipse中，選擇OnboardingRequest.java文件，然后右鍵單擊“Run As> Java Application”。如果從IDE中運(yùn)行程序，結(jié)果應(yīng)該相同（通常顯示在IDE的控制臺(tái)視圖中）。

您已經(jīng)在這個(gè)簡(jiǎn)單的Java程序中成功嵌入了Activiti的BPM引擎。

4.部署流程定義

我們現(xiàn)在準(zhǔn)備為Activiti Engine添加額外的BPM邏輯。

為此，正如我們的OnboardingRequest Java類(lèi)的名稱(chēng)所示，我們將使用簡(jiǎn)單的Onboarding過(guò)程。在這個(gè)例子中，我們將輸入數(shù)據(jù)。然后，如果經(jīng)驗(yàn)?zāi)陻?shù)超過(guò)3，則將發(fā)布個(gè)性化入職歡迎消息的任務(wù)。在該任務(wù)中，用戶將手動(dòng)將數(shù)據(jù)輸入到虛擬后端系統(tǒng)中。如果多年的經(jīng)驗(yàn)是3年或更短，那么簡(jiǎn)單地，通用地，自動(dòng)地將數(shù)據(jù)與虛擬后端系統(tǒng)集成。

Activiti的Process Engine符合BPMN 2.0標(biāo)準(zhǔn)。在視覺(jué)上，上面的過(guò)程可以這樣建模：

這個(gè)例子非常簡(jiǎn)單。并且，根據(jù)要求，可以通過(guò)幾種不同的方式對(duì)其進(jìn)行建模。雖然它也可以協(xié)調(diào)簡(jiǎn)單的流程，但請(qǐng)注意，Activiti可以處理數(shù)十個(gè)，數(shù)百個(gè)甚至數(shù)千個(gè)步驟的非常復(fù)雜的流程。

上面的可視化過(guò)程模型的基礎(chǔ)是BPMN的XML結(jié)構(gòu)。在這種情況下，XML文檔是onboarding.bpmn20.xml。這個(gè)快速入門(mén)不會(huì)深入到底層XML BPMN結(jié)構(gòu)的深度，而是專(zhuān)注于針對(duì)Activiti API開(kāi)發(fā)的機(jī)制以及將Activiti嵌入到您的應(yīng)用程序中。然而，為了支持下面的邏輯，這里是相關(guān)BPMN形狀和基礎(chǔ)XML中編寫(xiě)的定義邏輯的摘要：?

BPMN形狀	Onboarding.bpmn20.xml行	注釋
8	開(kāi)始活動(dòng)
9-15	用戶任務(wù)收集2個(gè)表單屬性：“fullName”和“yearsOfExperience”。請(qǐng)注意，第9行的候選組設(shè)置為“管理員”。
21-27	用戶任務(wù)收集1表單屬性：“personalWelcomeTime”。請(qǐng)注意，第22行的候選組設(shè)置為“管理員”。
31-35	腳本任務(wù)表示自動(dòng)數(shù)據(jù)輸入到虛擬后端。請(qǐng)注意，雖然簡(jiǎn)單，但有一個(gè)簡(jiǎn)單的腳本可以設(shè)置一個(gè)過(guò)程變量autoWelcomeTime（第34-35行）：var dateAsString = new Date().toString(); execution.setVariable("autoWelcomeTime", dateAsString);
18	定義“經(jīng)驗(yàn)歲月”專(zhuān)屬網(wǎng)關(guān)。（決定將產(chǎn)生一條或另一條路徑。）
37-39	使用yearsOfExperience變量表示“> 3”邏輯：${yearsOfExperience > 3}
18,36	在專(zhuān)用網(wǎng)關(guān)（第18行）上，注意指向“automatedIntroPath（第36行）”的默認(rèn)節(jié)，表示條件“> 3”的邏輯“else”。
298	結(jié)束事件

文件：$ mvnProject / src/ main / java / com / example / OnboardingRequest.java

添加行	說(shuō)明
25-27	加載提供的BPMN模型并將其部署到Activiti Process Engine。
28-33	檢索已部署的模型，證明它位于Activiti存儲(chǔ)庫(kù)中。

有關(guān)BPMN及其在Activiti中的使用的更多信息，請(qǐng)參閱Activiti?用戶指南中的各個(gè)部分。

下載onboarding.bpmn20.xml文件，下面的整個(gè)XML結(jié)構(gòu)，并將onboarding.bpmn20.xml文件復(fù)制到路徑$mvnProject/ src / main / resources /。

筆記：

這里感興趣的關(guān)鍵輸出是列表行，它記錄了進(jìn)程名稱(chēng)“Onboarding”和“onboarding：1：4”的唯一進(jìn)程ID（包括部署版本）

您的應(yīng)用程序現(xiàn)在在運(yùn)行時(shí)部署Onboarding進(jìn)程。

5.運(yùn)行流程實(shí)例

部署的進(jìn)程可以使用Activiti API來(lái)啟動(dòng)，運(yùn)行，查看歷史記錄以及以其他方式管理流程實(shí)例。此快速入門(mén)使用Java代碼運(yùn)行流程實(shí)例。

有關(guān)使用Restful Services管理流程實(shí)例的示例，請(qǐng)參閱Sample Onboarding Quick Start。

將Activiti的日志記錄級(jí)別從DEBUG設(shè)置為WARN，如下面的第1行所示。

文件：$ mvnProject /src / main / resources / log4j.properties

log4j.rootLogger=WARN, ACT

log4j.appender.ACT=org.apache.log4j.ConsoleAppender

log4j.appender.ACT.layout=org.apache.log4j.PatternLayout

log4j.appender.ACT.layout.ConversionPattern=%d{hh:mm:ss,SSS} [%t] %-5p %c %x - %m%n

重要提示：??以下示例代碼說(shuō)明了Activiti基于標(biāo)準(zhǔn)的可嵌入流程引擎的靈活性和強(qiáng)大功能。但是，此代碼在錯(cuò)誤處理，代碼組織和一般設(shè)計(jì)方面并不代表最佳實(shí)踐。相反，目的是快速說(shuō)明許多想法，以便熟悉Activiti的力量。根據(jù)您自己的需要重新考慮以下示例。

雖然簡(jiǎn)單，但這個(gè)嵌入式示例顯示了您的應(yīng)用程序如何將流程邏輯外部化為基于標(biāo)準(zhǔn)的建模和代碼友好的開(kāi)發(fā)模型。

6.用Java編寫(xiě)服務(wù)任務(wù)

如前所述，我們的流程有一個(gè)活動(dòng)“通用和自動(dòng)數(shù)據(jù)輸入”（一種虛假的后端調(diào)用），當(dāng)入門(mén)年經(jīng)驗(yàn)不超過(guò)3時(shí)，它有條件地運(yùn)用。如所提供的，這是一個(gè)“腳本任務(wù)”。在這種情況下，執(zhí)行了一小段Javascript，說(shuō)明了系統(tǒng)處理步驟。我們將把這個(gè)腳本任務(wù)遷移到Java中，以說(shuō)明Java的全部功能如何滿足各種流程要求。

創(chuàng)建一個(gè)新的Java類(lèi)，如下所示：

文件：$ mvnProject /src / main / java / com / example / AutomatedDataDelegate.java

package com.example;

import java.util.Date;

importorg.activiti.engine.delegate.DelegateExecution;

importorg.activiti.engine.delegate.JavaDelegate;

publicclassAutomatedDataDelegate implements JavaDelegate {

? @Override

? publicvoidexecute(DelegateExecutionexecution) throws Exception {

? ? Date now = new Date();

? ? execution.setVariable("autoWelcomeTime", now);

? ? System.out.println("Faux call to backend for ["?

? ? + execution.getVariable("fullName") + "]");

? }

}

文件：$ mvnProject /src / main / java / com / example / OnboardingRequest.java

添加行	說(shuō)明
13	顯示設(shè)置過(guò)程變量。在這種情況下，變量autoWelcomeTime與當(dāng)前時(shí)間。
14	顯示檢索流程變量。

將腳本任務(wù)更改為指向AutomatedDataDelegate的服務(wù)任務(wù)。

之前：

文件：$ mvnProject /src / main / resources / onboarding.bpmn20.xml

<?xml version="1.0"encoding="UTF-8"?>

? <process id="onboarding"name="Onboarding"isExecutable="true">

? ? <scriptTask id="automatedIntro"name="Generic and Automated Data Entry"scriptFormat="javascript"activiti:autoStoreVariables="false">

? ? ? <script><![CDATA[var dateAsString = newDate().toString();

execution.setVariable("autoWelcomeTime", dateAsString);]]></script>

? ? </scriptTask>

...

后：

文件：$ mvnProject /src / main / resources / onboarding.bpmn20.xml

<?xml version="1.0" encoding="UTF-8"?>

? <process id="onboarding"name="Onboarding"isExecutable="true">
