一、概述
Activiti相对Jbpm来说，与Spring整合更加完美，具体可见本文的详细介绍
二、开发环境的准备
1. Maven的环境任务，请参考第一篇 （Activiti入门篇—Maven的环境准备）
2. Activiti的Eclipse插件安装
插件更新地址：http://activiti.org/designer/update/
安装完成后，可以设计一请假的流程，如下所示：
右键holidayRequest.bpmn文件，用Xml Editor打开，可以看到其生成的XML文件格式：
3. 安装数据库Mysql(略)
创建一数据库名为activiti，暂时不放表
三、Activiti与Spring的整合
1. 新建Maven项目
2. 加入依赖包
依赖的pom.xml文件如下所示:
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.hotent.demo</groupId> <artifactId>activiti</artifactId> <version>1.0.0-SNAPSHOT</version> <dependencies> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-engine</artifactId> <version>5.15.1</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-spring</artifactId> <version>5.15.1</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>3.2.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>3.2.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>3.2.2.RELEASE</version> </dependency> <dependency> <groupId>commons-dbcp</groupId> <artifactId>commons-dbcp</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>3.2.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>3.2.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>3.2.2.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>3.2.2.RELEASE</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.5</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.11</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.6</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-model</artifactId> <version>5.15.1</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-bpmn-converter</artifactId> <version>5.15.1</version> </dependency> <dependency> <groupId>org.activiti</groupId> <artifactId>activiti-process-validation</artifactId> <version>5.15.1</version> </dependency> <dependency> <groupId>joda-time</groupId> <artifactId>joda-time</artifactId> <version>2.1</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl-over-slf4j</artifactId> <version>1.7.6</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>1.7.6</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>3.1</version> </dependency> <dependency> <groupId>javax.annotation</groupId> <artifactId>javax.annotation-api</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>commons-io</groupId> <artifactId>commons-io</artifactId> <version>2.4</version> </dependency> </dependencies> </project>
【说明】：
在增加Activiti的包时，可以参考Activiti本身的依赖包的管理，当执行BaseTestCase发现缺少包时，可以从该文件找到对应的依赖包及其版本的要求。
3. 增加Spring中的Activiti配置文件
<?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="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/activiti" /> <property name="username" value="root" /> <property name="password" value="000" /> <property name="defaultAutoCommit" value="false" /> </bean> <bean id="processEngineConfiguration" class="org.activiti.engine.impl.cfg.StandaloneProcessEngineConfiguration"> <property name="dataSource" ref="dataSource" /> <property name="databaseType" value="mysql"/> <property name="databaseSchemaUpdate" value="true" /> <property name="jobExecutorActivate" 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="managementService" factory-bean="processEngine" factory-method="getManagementService" /> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> </beans>
4. 编写TestCase
其代码如下：
package com.hotent.test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.transaction.TransactionConfiguration;
import org.springframework.transaction.annotation.Transactional;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:spring-activiti.xml"})
@TransactionConfiguration(transactionManager="transactionManager", defaultRollback=false)
@Transactional
public class BaseTestCase extends AbstractTransactionalJUnit4SpringContextTests{
@Test
public void test(){
System.out.println ("test");
}
}
执行以上TestCase,若控制台输出test则表示已经成功整合了Activiti与Spring，并且可以登录数据库中查看其已经创建好Activiti对应的表，如下图所示：
5. 发布测试的流程示例
package com.hotent.test.bpm;
import java.io.IOException;
import java.io.InputStream;
import java.util.List;
import javax.annotation.Resource;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.TaskService;
import org.activiti.engine.repository.Deployment;
import org.activiti.engine.repository.ProcessDefinition;
import org.activiti.engine.task.Task;
import org.junit.Assert;
import org.junit.Test;
import com.hotent.test.BaseTestCase;
public class BpmDefinitionTest extends BaseTestCase{
@Resource
private RepositoryService repositoryService;
@Resource
private RuntimeService runtimeService;
@Resource
TaskService taskService;
@Test
public void testDeploy() throws IOException{
InputStream is=readXmlFile();
Assert.assertNotNull(is);
//发布流程
Deployment deployment=repositoryService.createDeployment().addInputStream("bpmn20.xml", is).name("holidayRequest").deploy();
Assert.assertNotNull(deployment);
System.out.println("deployId:" + deployment.getId());
//查询流程定义
ProcessDefinition processDefinition=repositoryService.createProcessDefinitionQuery().deploymentId(deployment.getId()).singleResult();
Long businessKey=new Double(1000000*Math.random()).longValue();
//启动流程
runtimeService.startProcessInstanceById(processDefinition.getId(),businessKey.toString());
//查询任务实例
List<Task> taskList=taskService.createTaskQuery().processDefinitionId(processDefinition.getId()).list();
Assert.assertNotNull(taskList==null);
Assert.assertTrue(taskList.size()>0);
for(Task task:taskList){
System.out.println("task name is " + task.getName() + " ,task key is " + task.getTaskDefinitionKey());
}
}
public InputStream readXmlFile() throws IOException{
String filePath="holidayRequest.bpmn";
return Class.class.getClass().getResource("/"+filePath).openStream();
}
}
执行结果如下所示：
四、示例配置项目具体示例文件如：
