二、application.yml

server:
  port: 8087
  tomcat:
    uri-encoding: UTF-8

spring:
  datasource:
    url: jdbc:mysql://localhost/activiti6?characterEncoding=utf8&useSSL=false&serverTimezone=UTC&rewriteBatchedStatements=true&nullCatalogMeansCurrent=true
    username: root
    password: 111111
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    druid:
      # 下面为连接池的补充设置，应用到上面所有数据源中
      # 初始化大小，最小，最大
      initial-size: 5
      min-idle: 5
      max-active: 20
      # 配置获取连接等待超时的时间
      max-wait: 60000
      # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
      time-between-eviction-runs-millis: 60000
      # 配置一个连接在池中最小生存的时间，单位是毫秒
      min-evictable-idle-time-millis: 300000
      validation-query: SELECT 1 FROM DUAL
      test-while-idle: true
      test-on-borrow: false
      test-on-return: false
      # 打开PSCache，并且指定每个连接上PSCache的大小
      pool-prepared-statements: true
      #   配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
      max-pool-prepared-statement-per-connection-size: 20
      filters: stat,wall
      use-global-data-source-stat: true
      # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
      connect-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000
  activiti:
    check-process-definitions: false
    #flase：       默认值。activiti在启动时，会对比数据库表中保存的版本，如果没有表或者版本不匹配，将抛出异常。（生产环境常用）
    #true：        activiti会对数据库中所有表进行更新操作。如果表不存在，则自动创建。（开发时常用）
    #create_drop： 在activiti启动时创建表，在关闭时删除表（必须手动关闭引擎，才能删除表）。（单元测试常用）
    #rop-create： 在activiti启动时删除原来的旧表，然后在创建新表（不需要手动关闭引擎）。
    database-schema-update: true

三、Aplication.java

注意：@SpringBootApplication  后添加   exclude = {SecurityAutoConfiguration.class }

package com.badcat;

import org.activiti.spring.boot.SecurityAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
    * 启动程序
 */
@SpringBootApplication(exclude = {SecurityAutoConfiguration.class })
public class Application
{
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

四、运行Aplication.java，发现数据库多出了28张表

 五、创建config类

import org.activiti.engine.*;
import org.activiti.spring.ProcessEngineFactoryBean;
import org.activiti.spring.SpringProcessEngineConfiguration;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.transaction.PlatformTransactionManager;

import javax.sql.DataSource;

/**
 * @author badcat
 * Date 2021/3/10
 * Time 16:01
 */
@Configuration
public class ActivitiConfig {
    @Autowired
    private DataSource dataSource;
    @Autowired
    private PlatformTransactionManager platformTransactionManager;

    private SpringProcessEngineConfiguration springProcessEngineConfiguration(){
        SpringProcessEngineConfiguration spec = new SpringProcessEngineConfiguration();
        spec.setDataSource(dataSource);
        spec.setTransactionManager(platformTransactionManager);
        spec.setDatabaseSchemaUpdate("true");
        return spec;
    }

    private ProcessEngineFactoryBean processEngine(){
        ProcessEngineFactoryBean processEngineFactoryBean = new ProcessEngineFactoryBean();
        processEngineFactoryBean.setProcessEngineConfiguration(springProcessEngineConfiguration());
        return processEngineFactoryBean;
    }

    @Bean
    public RepositoryService repositoryService() throws Exception{
        return processEngine().getObject().getRepositoryService();
    }
    @Bean
    public RuntimeService runtimeService() throws Exception{
        return processEngine().getObject().getRuntimeService();
    }
    @Bean
    public TaskService taskService() throws Exception{
        return processEngine().getObject().getTaskService();
    }
    @Bean
    public HistoryService historyService() throws Exception{
        return processEngine().getObject().getHistoryService();
    }
    @Bean
    public FormService formService() throws Exception{
        return processEngine().getObject().getFormService();
    }
}

六、创建测试类

其中BPMN/process.bpmn是提前准备的流程定义文import org.activiti.engine.RepositoryServicimport org.activiti.engine.repository.Deployment;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

/**
 * @author badcat
 * Date 2021/3/10
 * Time 16:09
 */
@RunWith(SpringRunner.class)
@SpringBootTest
public class Deployment_test {

    @Autowired
    private RepositoryService repositoryService;

    @Test
    public void initDeploymentBPMN(){
        String filename="BPMN/process.bpmn";
        Deployment deployment=repositoryService.createDeployment()
                .addClasspathResource(filename)
                .deploy();
        System.out.println(deployment.getId()); 
　　} 
}

运行就可以看到数据库中的数据了。
