在activiti.cfg.xml中进行配置 我们可以在activiti.cfg.xml中添加关于数据库的基础配置

创建一个测试类，调用activiti的工具类，直接生成activiti需要的数据库表。

package com.nanjing;
    
    import org.activiti.engine.ProcessEngine;
    import org.activiti.engine.ProcessEngines;
    import org.junit.Test;
    
    /**
     * @author ：楼兰

     * @description:

    public class TestCreateTable {
        /**
         * 生成 activiti的数据库表
         */
        @Test
        public void testCreateDbTable() {
            //默认创建方式
            ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();
            //通用的创建方式，指定配置文件名和Bean名称
    //        ProcessEngineConfiguration processEngineConfiguration = ProcessEngineConfiguration.createProcessEngineConfigurationFromResource("activiti.cfg.xml", "processEngineConfiguration");
    //        ProcessEngine processEngine1 = processEngineConfiguration.buildProcessEngine();
            System.out.println(processEngine);
    
        }
    }

在mysql中新建activiti数据库，用来保存流程定义数据

CREATEDATABASEactivitiDEFAULTCHARACTERSETutf8;

![61bed1d9cf824bd6908b7e38e8a25994.png][]

执行代码生成25张表，activiti需要依赖的业务表有25张，

而activiti中提供了工具帮我们生成所需要 的表。
