1.根据快速开始操作，创建maven工程，配置相关依赖， $actVer改为6.0.0 本例使用mysql替代h2

<dependency>

    <groupId>org.activiti</groupId>

    <artifactId>activiti-engine</artifactId>

    <version>6.0.0</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>mysql</groupId>

    <artifactId>mysql-connector-java</artifactId>

    <version>6.0.6</version>

</dependency>

2.加入配置文件/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

3.mysql创建数据库并连接

4.获取流程引擎对象ProcessEngine

4.1.通过代码设置

// 引擎配置

ProcessEngineConfiguration cfg = new StandaloneProcessEngineConfiguration()

        .setJdbcUrl("jdbc:mysql://localhost:3306/activiti").setJdbcUsername("root")

        .setJdbcPassword("pwd")

        .setJdbcDriver("com.mysql.jdbc.Driver")

        .setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);

// 获取流程引擎对象

ProcessEngine processEngine = cfg.buildProcessEngine();

4.2.通过activiti.cfg.xml配置文件

ProcessEngineConfiguration cfg = ProcessEngineConfiguration

        .createProcessEngineConfigurationFromResource("activiti.cfg.xml");

ProcessEngine processEngine = cfg.buildProcessEngine();

配置文件activiti.cfg.xml

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

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans   http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration">

        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/activiti"/>

        <property name="jdbcDriver" value="com.mysql.jdbc.Driver"/>

        <property name="jdbcUsername" value="root"/>

        <property name="jdbcPassword" value="pwd"/>

        <property name="databaseSchemaUpdate" value="true"/>

    </bean>

</beans>

执行后初始化数据表如下



5.安装BPM插件

5.1 IDEA搜索并安装BPM插件 Business Process Management

加入示例中的xml /src/main/resources/onboarding.bpmn20.xml

打开xml可以看到流程图



5.2.IDEA的BPM插件使用体检较差，建议使用eclipse插件

安装插件 Install New Software http://activiti.org/designer/update/

Activiti 5.10支持直接部署扩展名为bpmn的流程文件，设计器打开如下：

6.下面就可以为所欲为了

// 启动流程

ProcessInstance pi = processEngine.getRuntimeService().startProcessInstanceByKey("myProcess");

System.out.println("process id" + pi.getId());

System.out.println("process name" + pi.getName());

// 获取任务

TaskService taskService = processEngine.getTaskService();

List<Task> list = taskService.createTaskQuery().taskAssignee("lili").list();

System.out.println("任务个数" + list.size());

if (list != null && list.size() > 0) {

    for (Task t : list) {

        System.out.print(t.getId() + ",");

        System.out.print(t.getName() + ",");

        System.out.print(t.getAssignee() + ",");

        System.out.println(t.getProcessInstanceId());

    }

}
