最近做了个项目需要用到工作流, 工作流引擎有很多, 经比较最终选择了Activity 进行开发;
在使用之前需要搞清楚什么是工作流, 流程引擎, 流程实例 等概念, 以及对应表的含义[注: Activiti工作流共23张表, JBPM共18张表] 使自己快速熟悉工作流的这一套运作流程;
开发工具:
Eclipse (我使用的版本是 eclipse-jee-oxygen-M3-win32-x86_64)
1. 下载开发工具: 略...
2. 开发工具安装Activiti插件: 略...
3. 新建maven项目
工具栏点击"File-New-Other..." 选择 "Maven-Maven Project" 后点击Next 勾选上 Create a simple project (skip archetype selection)
点击 Next 并填写项目信息
点击Finish创建项目
配置依赖jar包

通过测试代码自动创建工作流相关的23张表(创建数据库activiti_primary)
CreateTablesTest
1 package activiti;

3 import org.activiti.engine.ProcessEngine;
4 import org.activiti.engine.ProcessEngineConfiguration;
5 import org.activiti.engine.impl.cfg.ProcessEngineConfigurationImpl;
6 import org.junit.Test;
7
8 public class CreateTablesTest {
9
10 /**
11 * 测试创建activiti的23张表
12 */
13 @Test
14 public void createActivitiTablesTest() {
15 // 1. 创建流程引擎配置类
16 ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfigurationImpl.createStandaloneProcessEngineConfiguration();
17 // 设置流程引擎配置类
18 processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
19 processEngineConfiguration.setJdbcUrl("jdbc:mysql://127.0.0.1:3306/activiti_primary?useUnicode=true&characterEncoding=utf-8");
20 processEngineConfiguration.setJdbcUsername("root");
21 processEngineConfiguration.setJdbcPassword("root");
22
23 // 2. 设置是否自动创建表;
24 /**

26 * DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";先删除表再创建表
27 * DB_SCHEMA_UPDATE_TRUE = "true";如果表不存在，自动创建表
28 */
29 processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfigurationImpl.DB_SCHEMA_UPDATE_TRUE);
30
31 // 3. 根据流程引擎配置类构建流程引擎
32 ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
33 }
34
35 /**
36 * 从流程引擎中获取流程的service
37 */
38 @Test
39 public void getServiceFromProcessEngine() {
40
41 }
42
43 }
再次查看数据库时发现23张表已经创建完成
