Activiti配置实例以及Spring集成配置


public class TestDB {public static void main(String[] args) {//1。 创建Activiti配置对象的实例ProcessEngineConfiguration configuration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();//2. 设置数据库连接信息// 设置数据库地址configuration.setJdbcUrl("jdbc:mysql://localhost:3306/activiti_test?createDatabaseIfNotExist=true");// 数据库驱动configuration.setJdbcDriver("com.mysql.jdbc.Driver");// 用户名configuration.setJdbcUsername("root");// 密码configuration.setJdbcPassword("123456");// 设置数据库建表策略(默认不会建表)
  configuration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);//3. 使用配置对象创建流程引擎实例（检查数据库连接等环境信息是否正确）ProcessEngine processEngine = configuration.buildProcessEngine();System.out.println(processEngine);}

 public void testDBByProperties() throws Exception {// 1。 加载classpath下名为activiti.cfg.xml文件，创建核心流程引擎对象ProcessEngine processEngine = ProcessEngineConfiguration.
　　　　　　　　　　　　　　　　　　 createProcessEngineConfigurationFromResource("activiti.cfg.xml").
　　　　　　　　　　　　　　　　　　 buildProcessEngine();System.out.println(processEngine);//或者 private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();此方法默认和上面一样
 }
}

核心API介绍

　　1、ProcessEngine

　　　　在Activiti中最核心的类，其他的类都是由他而来。

　　　　ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

　　　　可以通过processEngine 的get产生以下Service

RepositoryService	管理流程定义
RuntimeService	执行管理，包括启动、推进、删除流程实例等操作
TaskService	任务管理
HistoryService	历史管理(执行完的数据的管理)
IdentityService	组织机构管理
FormService	一个可选服务，任务表单管理
ManagerService
