Activiti 环境配置从无到有及学习心得(文档待续...)
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; 2 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 /** 25 * String DB_SCHEMA_UPDATE_FALSE = "false";不能自动创建表，需要表存在 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
