springboot-flowable

介绍

springboot-flowable 快速开发工作流

软件架构

springboot + flowable + modeler + idm

springboot version : 2.1.5

flowable version : 6.4.0

==注意:== 版本需于数据库 act_ge_property 相同

​ 需要先登录 http://127.0.0.1:8080/expense/idm/index.html

​ account: admin

​ pwd : test ​ 再访问: http://127.0.0.1:8080/expense 创建设计器

使用说明

  1. 将flowable的依赖加入到POM中即可,flowable使用需要一个数据库,这里为了方便我选择mysql
  2. 增加 mybatis, modeler,idm 等配置

        <flowable.version>6.4.0</flowable.version>

2.yml 文件配置

增加: idm, modeler , mybatis , servlet 等配置

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/flowable?autoReconnect=true&useUnicode=true&characterEncoding=utf8&useSSL=false&serverTimezone=CTT
    username: root
    password: 123456
  security:
    filter:
      dispatcher-types: REQUEST,FORWARD,ASYNC
flowable:
  #关闭定时任务JOB
  async-executor-activate: false
  common:
    app:
      idm-url: http://localhost:8080/expense/
  idm:
    app:
      admin:
        user-id: admin
        password: test
        first-name: admin
        last-name: admin
  rest:
    app:
      authentication-mode: verify-privilege
  modeler:
    app:
      rest-enabled: true
  database-schema-update: true
mybatis:
  mapper-locations: classpath:/META-INF/modeler-mybatis-mappings/*.xml
  config-location: classpath:/META-INF/mybatis-config.xml
  configuration-properties:
    prefix:
    blobType: BLOB
    boolValue: TRUE
server:
  servlet:
    context-path: /expense

这样操作后,flowable与springBoot的整个就完成了!

然后就可以运行了,初次运行时flowable会将自动执行flowable中的初始化脚本完成工作流所需要的数据表的建立,如果指定的数据库中还未创建过flowable的相关数据表的话。

其中的两个代理类为:

import org.flowable.engine.delegate.TaskListener;
import org.flowable.task.service.delegate.DelegateTask;
 
public class ManagerTaskHandler implements TaskListener {
 
    @Override
    public void notify(DelegateTask delegateTask) {
        delegateTask.setAssignee("经理");
    }
 
}
public class BossTaskHandler implements TaskListener {
 
    @Override
    public void notify(DelegateTask delegateTask) {
        delegateTask.setAssignee("老板");
    }
 
}

尽管上面的BPMN文件很长,但放心,毕竟那是通过相关的工具生成出来的,对于核心的逻辑部分也很少(主要在process 标签内) ,如需要详细了解的可自行学习下BPMN的标签即可!当然,在flowable的使用文档中也有相关的描述,详见:Creating a ProcessEngine

这样当此框架启动的时候它会默认加载resource目录下的processes时就可以将此流程配置加载到数据库进行持久化了

        OutputStream out = null;

            if (in != null) {
                in.close();
            }

通过传入流程ID生成当前流程的流程图给前端,如果流程中使用到中文且生成的图片是乱码的,则需要进配置下字体:

/**
 * @author haiyangp
 * date:  2018/4/7
 * desc: flowable配置----为放置生成的流程图中中文乱码
 */
@Configuration
public class FlowableConfig implements EngineConfigurationConfigurer<SpringProcessEngineConfiguration> {
 
    @Override
    public void configure(SpringProcessEngineConfiguration engineConfiguration) {
        engineConfiguration.setActivityFontName("宋体");
        engineConfiguration.setLabelFontName("宋体");
        engineConfiguration.setAnnotationFontName("宋体");
    }
} 

测试请求

1.先启动好此项目,然后创建一个流程:

访问:http://localhost:8080/expense/add?userId=123&money=123321

返回:提交成功.流程Id为:2501

2.查询待办列表:

访问:http://localhost:8080/expense/list?userId=123

输出:Task[id=2507, name=出差报销]

3.同意:

​ ==注意 : 带的是taskid==

访问:http://localhost:8080/expense/apply?taskId=2507

返回:processed ok!

4.生成流程图:

访问: http://localhost:8080/expense/processDiagram?processId=2501

流程设计器 modeler

解压 idm, modeler war包 导入两个war中的 static 包下的文件

重写两个配置类

AppDispatcherServletConfiguration.java ApplicationConfiguration springboot 启动类 import 两个配置类

![说明](assets/说明.png)@Import({
        ApplicationConfiguration.class,
        AppDispatcherServletConfiguration.class
})
@ComponentScan(basePackages = {"com.example.demo"})
@EnableTransactionManagement
@SpringBootApplication
public class DemoApplication {

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

}

添加国际化文件
