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());
}
}
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。
