方式一：通過程式碼初始化工作流的23張表

/**
  * 通過程式碼初始化工作流的23張表
  */
@Test
public void createActivitiTable(){
   ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration
           .createStandaloneProcessEngineConfiguration();
   // 連線數控的配置
   processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver"
 
);
   processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/acti?useUnicode=true&characterEncoding=utf8");
   processEngineConfiguration.setJdbcUsername("root");
   processEngineConfiguration.setJdbcPassword("jing2018");

   /**
    * DB_SCHEMA_UPDATE_FALSE = "false";不能自動建立表，需要表存在
    * DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";先刪除表再建立表
    * DB_SCHEMA_UPDATE_TRUE = "true";如果表不存在，自動建立表
    */
 

   processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
   // ProcessEngine（流程引擎），工作流的核心物件
   ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
   System.out.println("processEngine:" + processEngine);
}

方式二：通過配置檔案初始化

/**
  * 使用配置檔案建立工作流資料表
  */
 

 @Test
 public void createTableByConfig(){
     ProcessEngine processEngine = ProcessEngineConfiguration
             .createProcessEngineConfigurationFromResource("activiti.cfg.xml").buildProcessEngine();
     System.out.println("processEngine:"+processEngine);
 }
