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.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
        dependency>
 
        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-testartifactId>
            <scope>testscope>
        dependency>
        
        <dependency>
            <groupId>org.flowablegroupId>
            <artifactId>flowable-spring-boot-starterartifactId>
            <version>7.0.1version>
        dependency>
 
 
        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
            <version>8.0.33version>
        dependency>
 
        <dependency>
            <groupId>com.alibabagroupId>
            <artifactId>druidartifactId>
            <version>1.2.20version>
        dependency>
        <dependency>
            <groupId>org.projectlombokgroupId>
            <artifactId>lombokartifactId>
            <scope>annotationProcessorscope>
        dependency>
 
        
        <dependency>
            <groupId>org.slf4jgroupId>
            <artifactId>slf4j-apiartifactId>
            <version>2.0.13version>
        dependency>
 
        <dependency>
            <groupId>org.slf4jgroupId>
            <artifactId>slf4j-reload4jartifactId>
            <version>2.0.13version>
            <scope>testscope>
        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流程定义信息。
