1.根據(jù)快速開(kāi)始操作输涕，創(chuàng)建maven工程放航，配置相關(guān)依賴磕秤， $actVer改為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創(chuàng)建數(shù)據(jù)庫(kù)并連接

4.獲取流程引擎對(duì)象ProcessEngine
4.1.通過(guò)代碼設(shè)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);
// 獲取流程引擎對(duì)象
ProcessEngine processEngine = cfg.buildProcessEngine();

4.2.通過(guò)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>

執(zhí)行后初始化數(shù)據(jù)表如下

5.安裝BPM插件
5.1 IDEA搜索并安裝BPM插件 Business Process Management

加入示例中的xml /src/main/resources/onboarding.bpmn20.xml
打開(kāi)xml可以看到流程圖

6.下面就可以為所欲為了

// 啟動(dòng)流程
ProcessInstance pi = processEngine.getRuntimeService().startProcessInstanceByKey("myProcess");
System.out.println("process id" + pi.getId());
System.out.println("process name" + pi.getName());

// 獲取任務(wù)
TaskService taskService = processEngine.getTaskService();
List<Task> list = taskService.createTaskQuery().taskAssignee("lili").list();
System.out.println("任務(wù)個(gè)數(shù)" + 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());
    }
}
