Activiti6.0工作流整合SpringBoot2.3.2

记录一下整合的过程。本期目标：依赖都加入项目，启动类，配置修改好以后，项目可以正常启动。成功启动项目以后，自动创建数据库表成功

环境说明

mysql：5.7.4

spring boot: 2.3.2

activiti: 6.0

mybatisplus: 3.4.3.4

启动类

package com.back.system.approval;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author 维维
 */

@SpringBootApplication(exclude = org.activiti.spring.boot.SecurityAutoConfiguration.class)
public class ApprovalApplication {

    public static void main(String[] args) {
        SpringApplication.run(ApprovalApplication.class, args);
    }

}

注 ： 启动项目没有自动创建数据库表，在sql连接后面加 nullCatalogMeansCurrent=true 然后重启项目

启动项目，创建数据库表成功。本期目标就算完成
