本文介绍了如何在IDEA中安装actiBPM插件，创建Spring Boot工程并引入Activiti依赖，绘制工作流流程图，以及通过Java API进行Activiti的相关操作，包括流程定义、部署、启动、任务处理和监听器使用。

1. IDEA 安装 actiBPM 插件

plugins中可直接搜索activiBPM安装
但是我的idea一直搜索不到activiBPM
建议离线安装,插件下载地址
https://github.com/Activiti/Activiti-Designer/releases
在这里插入图片描述

2. 创建工程引入依赖

创建一个spring boot工程
pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>
    <artifactId>study</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>study</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-engine</artifactId>
            <version>6.0.0</version>
        </dependency>

        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <version>1.4.199</version>
        </dependency>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>20.0</version>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

3. 绘制工作流流程图

在这里插入图片描述
为每个节点属性填写id、name 、Formt等信息
如果网关，为flow填写condition,如取消提交表单连线
如果有监听事件，添加对应的tasklistener或execution listener

对应的文件如下(复制second_approval.bpmn为second_approval.bpmn20.xml)：
second_approval.bpmn20.xml

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

  <process id="second_approve" isClosed="false" isExecutable="true" name="二级审批流程" processType="None">
    <startEvent id="startEvent" name="开始节点"/>
    <userTask activiti:exclusive="true" id="submitForm" name="填写审批信息">
      <extensionElements>
        <activiti:formProperty id="message" name="申请信息" required="true" type="string"/>
        <activiti:formProperty id="name" name="申请人姓名" required="true" type="string"/>

        <activiti:formProperty id="submitType" name="确认申请" required="true" type="string"/>
      </extensionElements>
    </userTask>
    <sequenceFlow id="_4" sourceRef="startEvent" targetRef="submitForm"/>
    <exclusiveGateway gatewayDirection="Unspecified" id="decideSubmit" name="提交OR取消"/>
    <sequenceFlow id="_6" sourceRef="submitForm" targetRef="decideSubmit"/>
    <userTask activiti:exclusive="true" id="tl_approve" name="主管审批">
      <extensionElements>
        <activiti:formProperty id="tlApprove" name="主管审批结果" readable="true" required="true" type="string" writable="true"/>
        <activiti:formProperty id="tlMessage" name="主管备注" required="true" type="string"/>
      </extensionElements>
    </userTask>
    <sequenceFlow id="_8" sourceRef="decideSubmit" targetRef="tl_approve">
      <conditionExpression xsi:type="tFormalExpression"><![CDATA[${submitType=="y" || submitType=="Y"}]]></conditionExpression>
    </sequenceFlow>
    <exclusiveGateway gatewayDirection="Unspecified" id="decideTLApprove" name="主管审批校验
