Spring，Struts2，MyBatis，Activiti，Maven，H2，Tomcat集成（四）——Activiti集成
1、添加Activiti Maven依赖；
<!-- ==============================activiti=========================== -->
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-engine</artifactId>
<version>5.17.0</version>
</dependency>
<dependency>
<groupId>org.activiti</groupId>
<artifactId>activiti-spring</artifactId>
<version>5.17.0</version>
</dependency>
<!-- activiti需要log4j日志 -->
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.7.6</version>
</dependency>
2、Spring集成Activiti；
<!-- ===================================activiti配置=================================== -->
<!-- activiti配置 -->
<bean id="processEngineConfiguration" class="org.activiti.spring.SpringProcessEngineConfiguration">
<!-- 数据源 -->
<property name="dataSource" ref="dataSource" />
<!-- 配置事务管理器，统一事务 -->
<property name="transactionManager" ref="transactionManager" />
<!-- 设置建表策略 -->
<property name="databaseSchemaUpdate" value="true" />
<property name="jobExecutorActivate" value="false" />
<property name="asyncExecutorEnabled" value="true" />
<property name="asyncExecutorActivate" value="false" />
</bean>
<bean id="processEngine" class="org.activiti.spring.ProcessEngineFactoryBean">
<property name="processEngineConfiguration" ref="processEngineConfiguration" />
</bean>
<bean id="repositoryService" factory-bean="processEngine" factory-method="getRepositoryService" />
<bean id="runtimeService" factory-bean="processEngine" factory-method="getRuntimeService" />
<bean id="taskService" factory-bean="processEngine" factory-method="getTaskService" />
<bean id="historyService" factory-bean="processEngine" factory-method="getHistoryService" />
<bean id="formService" factory-bean="processEngine" factory-method="getFormService" />
3、由于使用了log4j，在src/main/resources目录下添加log4j配置文件log4j.properties；
log4j.rootLogger=WARN, stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n
4、添加bpmn流程配置文件Interview.bpmn；
<?xml version="1.0" encoding="UTF-8"?>
<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL"
xmlns:activiti="http://activiti.org/bpmn"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
targetNamespace="Examples"
xsi:schemaLocation="http://www.omg.org/spec/BPMN/20100524/MODEL
http://www.omg.org/spec/BPMN/2.0/20100501/BPMN20.xsd">
<process id="Interview" name="某公司2012年实习生招聘流程">
<documentation>招聘工作流程</documentation>
<startEvent id="start" name="实习生招聘启动"/>
<userTask id="bishi" name="笔试" activiti:candidateGroups="人力资源部"/>
<sequenceFlow id="flow1" name="" sourceRef="start" targetRef="bishi"/>
<userTask id="yimian" name="技术一面" activiti:candidateGroups="技术部"/>
<sequenceFlow id="flow2" name="" sourceRef="bishi" targetRef="yimian"/>
<userTask id="ermian" name="技术二面" activiti:candidateGroups="技术部"/>
<sequenceFlow id="flow3" name="" sourceRef="yimian" targetRef="ermian"/>
<userTask id="hrmian" name="HR面" activiti:candidateGroups="人力资源部"/>
<sequenceFlow id="flow4" name="" sourceRef="ermian" targetRef="hrmian"/>
<userTask id="luyong" name="录用，发放Offer" activiti:candidateGroups="人力资源部"/>
<sequenceFlow id="flow5" name="" sourceRef="hrmian" targetRef="luyong"/>
<endEvent id="end" name="实习生招聘结束"/>
<sequenceFlow id="flow6" name="" sourceRef="luyong" targetRef="end"/>
</process>
</definitions>
5、添加Activiti测试类；
package com.coshaho.learn.service.test;
import java.util.List;
import org.activiti.engine.HistoryService;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.history.HistoricProcessInstance;
import org.activiti.engine.task.Task;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class ActivitiTest
{
public static void main(String[] args)
{
@SuppressWarnings("resource")
ApplicationContext ac = new ClassPathXmlApplicationContext(new String[]{"spring.xml"});
ProcessEngine processEngine = (ProcessEngine)ac.getBean("processEngine");
// 发布流程
RepositoryService repositoryService = processEngine.getRepositoryService();
repositoryService.createDeployment().addClasspathResource("Interview.bpmn").deploy();
// 启动流程实例
RuntimeService runtimeService = processEngine.getRuntimeService();
String processId = runtimeService.startProcessInstanceByKey("Interview").getId();
System.out.println("此次启动的流程实例为：" + processId);
// 获取人力资源任务
TaskService taskService = processEngine.getTaskService();
List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup("人力资源部").list();
System.out.println("******人力资源部任务列表******");
for (Task task : tasks)
{
if("笔试".equals(task.getName()))
{
System.out.println("张三领取笔试任务：" + task.getId());
taskService.claim(task.getId(), "张三");
}
else if("HR面".equals(task.getName()))
{
System.out.println("李四领取HR面任务：" + task.getId());
taskService.claim(task.getId(), "李四");
}
else
{
System.out.println("王五领取发放Offer任务：" + task.getId());
taskService.claim(task.getId(), "王五");
}
}
System.out.println("张三的笔试任务数量："+taskService.createTaskQuery().taskAssignee("张三").count());
tasks = taskService.createTaskQuery().taskAssignee("张三").list();
for (Task task : tasks)
{
System.out.println("张三处理笔试任务, id:"+task.getId());
taskService.complete(task.getId());
}
System.out.println("李四的HR面任务数量："+taskService.createTaskQuery().taskAssignee("李四").count());
tasks = taskService.createTaskQuery().taskAssignee("李四").list();
for (Task task : tasks)
{
System.out.println("李四处理HR面任务, id:"+task.getId());
taskService.complete(task.getId());
}
System.out.println("王五的发放Offer任务数量："+taskService.createTaskQuery().taskAssignee("王五").count());
tasks = taskService.createTaskQuery().taskAssignee("王五").list();
for (Task task : tasks)
{
System.out.println("王五处理发放Offer任务, id:"+task.getId());
taskService.complete(task.getId());
}
tasks = taskService.createTaskQuery().taskCandidateGroup("技术部").list();
System.out.println("******技术部任务列表******");
for (Task task : tasks)
{
if("技术一面".equals(task.getName()))
{
System.out.println("马六领取技术一面任务：" + task.getId());
taskService.claim(task.getId(), "马六");
}
else
{
System.out.println("胜七领取技术二面任务：" + task.getId());
taskService.claim(task.getId(), "胜七");
}
}
System.out.println("马六的技术一面任务数量："+taskService.createTaskQuery().taskAssignee("马六").count());
tasks = taskService.createTaskQuery().taskAssignee("马六").list();
for (Task task : tasks)
{
System.out.println("马六处理技术一面任务, id:"+task.getId());
taskService.complete(task.getId());
}
System.out.println("胜七的技术二面任务数量："+taskService.createTaskQuery().taskAssignee("胜七").count());
tasks = taskService.createTaskQuery().taskAssignee("胜七").list();
for (Task task : tasks)
{
System.out.println("胜七处理技术二面任务, id:"+task.getId());
taskService.complete(task.getId());
}
HistoryService historyService = processEngine.getHistoryService();
List<HistoricProcessInstance> historicProcessInstanceList = historyService
.createHistoricProcessInstanceQuery().list();
if(null != historicProcessInstanceList && 0 != historicProcessInstanceList.size())
{
for(HistoricProcessInstance hisInstance : historicProcessInstanceList)
{
System.out.println("历史流程, id = "+hisInstance.getId()
+ ", end time = " + hisInstance.getEndTime());
}
}
}
}
6、运行测试类，可得到如下结果。
此次启动的流程实例为：7504 ******人力资源部任务列表****** 王五领取发放Offer任务：5015 李四领取HR面任务：5023 张三领取笔试任务：7507 张三的笔试任务数量：1 张三处理笔试任务, id:7507 李四的HR面任务数量：1 李四处理HR面任务, id:5023 王五的发放Offer任务数量：1 王五处理发放Offer任务, id:5015 ******技术部任务列表****** 胜七领取技术二面任务：5020 马六领取技术一面任务：7513 马六的技术一面任务数量：1 马六处理技术一面任务, id:7513 胜七的技术二面任务数量：1 胜七处理技术二面任务, id:5020 历史流程, id = 2501, end time = null 历史流程, id = 4, end time = Sun Dec 27 18:31:14 COT 2015 历史流程, id = 5004, end time = null 历史流程, id = 7504, end time = null
同时，我们可以查看数据库，Activiti引擎自动创建以ACT开头的Activiti业务表。
