springboot 整合 Activiti6

news2024/9/29 3:26:45

1.添加maven依赖

<dependency>
    <groupId>org.activiti</groupId>
    <artifactId>activiti-spring-boot-starter-basic</artifactId>
    <version>6.0.0</version>
</dependency>

2.添加配置

spring:
  activiti:
    check-process-definitions: false
    database-schema-update: true
    #流程定义文件存放目录
    process-definition-location-prefix: "classpath:/processes/"
    history-level: full

3.修改数据库连接，在后面添加nullCatalogMeansCurrent=true的配置，否则不能自动建表

spring:
  datasource:
    hikari:
      driver-class-name: com.mysql.cj.jdbc.Driver
      #数据库名称以数字结尾，则必须用引号把值包起来，否则会报错
      jdbc-url: 'jdbc:mysql://localhost:3306/vwl?autoReconnect=true&nullCatalogMeansCurrent=true'
      username: 'root'
      password: 'root'

4.排除security依赖

因为activiti自带了spring-security依赖，而我自己的项目使用的是自定义的权限管理，所以需要排除该依赖

5.在resource目录下新建process目录

6.在idea中安装actiBPM插件

7.在process目录上右键新建流程文件

8.导入测试依赖，编写测试类

<!--test测试-->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
</dependency>

import com.azor.VwlApplication;
import org.activiti.engine.HistoryService;
import org.activiti.engine.RepositoryService;
import org.activiti.engine.RuntimeService;
import org.activiti.engine.repository.Deployment;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

import javax.annotation.Resource;

/**
 * @author zhuoping.yu
 * @date 2024/1/26 10:46
 */
@SpringBootTest(classes = VwlApplication.class)
public class ActivitiJpaTest01 {

    @Resource
    private RepositoryService repositoryService;
    @Resource
    private RuntimeService runtimeService;
    @Resource
    private HistoryService historyService;

    /**
     * 部署流程
     */
    @Test
    public void demo01(){
        Deployment deploy = repositoryService.createDeployment()
                .addClasspathResource("processes/activiti_demo01.bpmn")
                .addClasspathResource("processes/activiti_demo01.png")
                .name("整合JPA测试01")
                .deploy();
        System.out.println("部署ID:"+deploy.getId());
        System.out.println("部署名称"+deploy.getName());
    }
}
