springboot 整合 Activiti6

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: falsedatabase-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

</definitions>

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 {@Resourceprivate RepositoryService repositoryService;@Resourceprivate RuntimeService runtimeService;@Resourceprivate HistoryService historyService;/*** 部署流程*/@Testpublic 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());}
}

9.运行测试方法后，会自动生成act开头的28张数据表。

运行过程中出现异常：org.activiti.bpmn.exceptions.XMLException: 3 字节的 UTF-8 序列的字节 3 无效。

用notepad打开bpmn文件，将其中乱码的地方改为中文即可，其他网上的办法，我试了一些，没作用。因为后续需要把activiti流程的绘制转移到前端页面上，在此就不纠结了。
