flowable springboot集成

Flowable集成SpringBoot

1、引入依赖

2、application.yml

server:
  port: 8080
spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/flowable?useUnicode=true&characterEncoding=utf8&serverTimezone=GMT
    username: root
    password: 123456
    driver-class-name: com.mysql.jdbc.Driver
flowable:
  # 关闭异步，不关闭历史数据的插入就是异步的，会在同一个事物里面，无法回滚
  # 开发可开启会提高些效率，上线需要关闭
  async-executor-activate: true
  #  将databaseSchemaUpdate设置为true。当Flowable发现库与数据库表结构不一致时，会自动将数据库表结构升级至新版本。
  database-schema-update: true

3、配置Flowable生成流程图中文

@Configuration
public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
    /**
     * 防止生成的流程图中文乱码
     * @param springProcessEngineConfiguration
     */
    @Override
    public void configure(SpringProcessEngineConfiguration springProcessEngineConfiguration) {
        springProcessEngineConfiguration.setActivityFontName("宋体");
        springProcessEngineConfiguration.setLabelFontName("宋体");
        springProcessEngineConfiguration.setAnnotationFontName("宋体");
    }
}

4、启动类

@SpringBootApplication
public class AppApplication {
    public static void main(String[] args) {
        SpringApplication.run(AppApplication.class, args);
    }
}

5、流程图文件

在这里插入图片描述

ExpenseProcess.bpmn20.xml，放在resources/processes下可以自动部署：

6、监听器

public class BossTaskHandler implements TaskListener {
    @Override
    public void notify(DelegateTask delegateTask) {
        delegateTask.setAssignee("老板");
    }
}



public class ManagerTaskHandler implements TaskListener {
    @Override
    public void notify(DelegateTask delegateTask) {
        delegateTask.setAssignee("经理");

8、测试

8.1、启动流程

访问接口：http://localhost:8080/expense/add?userId=tom&money=300&descption=500元以下的流程测试

返回结果：提交成功.流程Id为：9d45818f-5634-11ee-b06b-a6b168beea52

在这里插入图片描述

8.2、查询待办列表

访问接口：http://localhost:8080/expense/list?userId=tom
返回结果： [Ljava.lang.Object;@61387942
控制台输出：

Task[id=9d4866c7-5634-11ee-b06b-a6b168beea52, name=出差报销]

8.3、批准任务

访问接口：http://localhost:8080/expense/apply?taskId=9d4866c7-5634-11ee-b06b-a6b168beea52

返回结果：processed ok!

8.4、生成流程图

由于我们到第三步的时候流程已经走完了，所以我们在重新新增一个任务，直接调用第一步创建流程即可

访问接口：http://localhost:8080/expense/add?userId=jerry&money=300&descption=500元以下的流程测试
返回结果：提交成功.流程Id为：676064e0-5635-11ee-b06b-a6b168beea52

然后访问接口：http://localhost:8080/expense/processDiagram?processId=676064e0-5635-11ee-b06b-a6b168beea52

在这里插入图片描述
