springboot与flowable（2）：流程部署

一、创建项目

创建springboot项目添加相关依赖。

<dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency><!--        flowable依赖包 springboot3以上需要使用7的版本 --><dependency><groupId>org.flowable</groupId><artifactId>flowable-spring-boot-starter</artifactId><version>7.0.1</version></dependency><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>8.0.33</version></dependency><dependency><groupId>com.alibaba</groupId><artifactId>druid</artifactId><version>1.2.20</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><scope>annotationProcessor</scope></dependency><!-- 日志相关 --><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-api</artifactId><version>2.0.13</version></dependency><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-reload4j</artifactId><version>2.0.13</version><scope>test</scope></dependency></dependencies>

在application.yml中添加相关配置。

spring:application:name: flowable-demo2datasource:driver-class-name: com.mysql.cj.jdbc.Driver# nullCatalogMeansCurrent=true 自动创建流程相关表url: jdbc:mysql://localhost:3306/flowable?useUnicode=true&allowPublicKeyRetrieval=true&characterEncoding=utf8&useSSL=false&nullCatalogMeansCurrent=trueusername: rootpassword: roottype: com.alibaba.druid.pool.DruidDataSource# flowable相关表
flowable:# true 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(建议开发时使用)database-schema-update: true# 关闭定时任务JOBasync-executor-activate: falseserver:port: 8081
logging:level:org:flowable: debug

二、导出流程定义

选择建模器应用程序

选择要导出的建模

点击导出按钮。

将导出的文件复制到项目中。

三、测试

编写测试代码。

package org.example.flowabledemo2;import org.flowable.engine.ProcessEngine;
import org.flowable.engine.RepositoryService;
import org.flowable.engine.repository.Deployment;
import org.flowable.engine.repository.DeploymentBuilder;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;@SpringBootTest
class FlowableDemo2ApplicationTests {// 提供对所有公开BPM和工作流操作的服务的访问。@Autowiredprivate ProcessEngine processEngine;// 提供对流程定义和部署的存储库的访问。@Autowiredprivate RepositoryService repositoryService;@Testvoid contextLoads() {// RepositoryService repositoryService1 = processEngine.getRepositoryService();DeploymentBuilder deployment = repositoryService.createDeployment();deployment.addClasspathResource("process01/FirstFlow.bpmn20.xml");deployment.name("第一个流程图");Deployment deploy = deployment.deploy();System.out.println("deploy.getId() = " + deploy.getId());}
}

运行并打印流程ID。
