Activity学习-初始化23张库表

1.此文章纯粹是我在学习activity过程中的总结，不喜勿喷。

/**使用代码创建工作流需要的23张表*/
@Test
public void createTable(){
ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
//连接数据库的配置
processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/itcast0711activiti?useUnicode=true&characterEncoding=utf8");
processEngineConfiguration.setJdbcUsername("root");
processEngineConfiguration.setJdbcPassword("123456");

/**
public static final String DB_SCHEMA_UPDATE_FALSE = "false";不能自动创建表，需要表存在
public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";先删除表再创建表
public static final String DB_SCHEMA_UPDATE_TRUE = "true";如果表不存在，自动创建表
*/
processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
//工作流的核心对象，ProcessEnginee对象
ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
System.out.println("processEngine:"+processEngine);
}

/**使用配置文件创建工作流需要的23张表*/
@Test
public void createTable_2(){
// ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml");
// //工作流的核心对象，ProcessEnginee对象
// ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();

ProcessEngine processEngine = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml") //
.buildProcessEngine();
System.out.println("processEngine:"+processEngine);
}
ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
