創建Activiti項目

 1.創建項目

 

 

 2.導入Activiti的jar包

項目上右擊創建lib文件夾

 

將jar包複製進lib文件夾

 

3.導入數據庫連接jar包

 

4.使用代碼創建Activiti用來存放流程數據的23張表

 

package junit;

import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.junit.Test;

public class TestActiviti {
    /**
     * 使用代碼創建工作流需要的23張表
     */
    @Test
    public void createTable(){
        ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration();
        //連接數據庫配置
        processEngineConfiguration.setJdbcDriver("com.mysql.jdbc.Driver");
        processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8");
        processEngineConfiguration.setJdbcUsername("root");
        processEngineConfiguration.setJdbcPassword("******");

        /**
          public static final String DB_SCHEMA_UPDATE_FALSE = "false";//不能自動創建表，需要表存在
          public static final String DB_SCHEMA_UPDATE_CREATE_DROP = "create-drop";//先刪除表再創建表
          public static final String DB_SCHEMA_UPDATE_TRUE = "true";//如果表不存在，自動創建表
          */
        processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
        //工作流的核心對象，ProcessEngine對象
        ProcessEngine processEngine = processEngineConfiguration.buildProcessEngine();
        System.out.println("processEngine:"+ processEngine);
    }
}

 5.優化使用配置文件來創建工作流需要的23張表

 

activiti.cfg.xml

        processEngineConfiguration.setJdbcUrl("jdbc:mysql://localhost:3306/activiti?useUnicode=true&characterEncoding=utf8");
        processEngineConfiguration.setJdbcUsername("root");
        processEngineConfiguration.setJdbcPassword("******");

        /**

          */
        processEngineConfiguration.setDatabaseSchemaUpdate(ProcessEngineConfiguration.DB_SCHEMA_UPDATE_TRUE);
     -->
