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-demo2

  datasource:
    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=true
    username: root
    password: root
    type: 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JOB
  async-executor-activate: false

server:
  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。
    @Autowired
    private ProcessEngine processEngine;
    // 提供对流程定义和部署的存储库的访问。
    @Autowired
    private RepositoryService repositoryService;

    @Test
    void 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。 

        在数据库中找到对应的数据。
