java调用Activiti实现二次开发

activiti发展到现在，发布版本已经到7了。Activiti项目是一项新的基于Apache许可的开源BPM平台，从基础开始构建，旨在提供支持新的BPMN 2.0标准，包括支持对象管理组（OMG），可以定义流程、执行流程并以不同方式对其实现运行。

一、activiti数据库表结构说明

表名默认以“ACT_”开头,并且表名的第二部分用两个字母表明表的用例，而这个用例也基本上跟Service API匹配。

ACT_GE_* : “GE”代表“General”（通用），用在各种情况下；

ACT_HI_* : “HI”代表“History”（历史），这些表中保存的都是历史数据，比如执行过的流程实例、变量、任务，等等。Activit默认提供了4种历史级别：

ACT_RE_* : “RE”代表“Repository”（仓库），这些表中保存一些‘静态’信息，如流程定义和流程资源（如图片、规则等）；

ACT_RU_* : “RU”代表“Runtime”（运行时），这些表中保存一些流程实例、用户任务、变量等的运行时数据。Activiti只保存流程实例在执行过程中的运行时数据，并且当流程结束后会立即移除这些数据；

表分类	表名称	表含义
资源库流程规则表	act_re_deployment	部署信息表
	act_re_model	流程设计模型部署表
	act_re_procdef	流程定义数据表
流程历史记录	act_hi_actinst	历史的流程实例
	act_hi_attachment	历史的流程附件
	act_hi_comment	历史的说明性信息
	act_hi_detail	历史的流程运行中的细节信息
	act_hi_identitylink	历史的流程运行过程中用户关系
	act_hi_procinst	历史的流程实例
	act_hi_taskinst	历史的任务实例
	act_hi_varinst	历史的流程运行中的变量信息
流程运行实例记录	act_ru_deadletter_job	执行失败任务表
	act_ru_integration	运行时流程人员表，主要存储任务节点与参与者的相关信息
	act_ru_event_subscr	运行时事件
	act_ru_execution	运行时流程执行实例
	act_ru_identitylink	运行时用户关系信息
	act_ru_job	运行时作业
	act_ru_suspended_job	运行时暂停任务
	act_ru_task	运行时任务
	act_ru_timer_job	运行时定时任务
	act_ru_variable	运行时变量表
通用数据表	act_ge_bytearray	二进制数据表
通用数据表	act_ge_property	属性数据表存储整个流程引擎级别的数据,初始化表结构时，会默认插入三条记录

二、activiti提供服务的七大对象

RepositoryService： Activiti 中每一个不同版本的业务流程的定义都需要使用一些定义文件，部署文件和支持数据 ( 例如 BPMN2.0 XML 文件，表单定义文件，流程定义图像文件等 )，这些文件都存储在 Activiti 内建的 Repository 中。Repository Service 提供了对 repository 的存取服务。
RuntimeService：在 Activiti 中，每当一个流程定义被启动一次之后，都会生成一个相应的流程对象实例。Runtime Service 提供了启动流程、查询流程实例、设置获取流程实例变量等功能。此外它还提供了对流程部署，流程定义和流程实例的存取服务。
TaskService：在 Activiti 中业务流程定义中的每一个执行节点被称为一个 Task，对流程中的数据存取，状态变更等操作均需要在 Task 中完成。Task Service 提供了对用户 Task 和 Form 相关的操作。它提供了运行时任务查询、领取、完成、删除以及变量设置等功能。
IdentityService： Activiti 中内置了用户以及组管理的功能，必须使用这些用户和组的信息才能获取到相应的 Task。Identity Service 提供了对 Activiti 系统中的用户和组的管理功能。
ManagementService： Management Service 提供了对 Activiti 流程引擎的管理和维护功能，这些功能不在工作流驱动的应用程序中使用，主要用于 Activiti 系统的日常维护。
HistoryService： Activiti 中的流程和状态 Task 均可以关联业务相关的数据。通过使用 Form Service 可以存取启动和完成任务所需的表单数据并且根据需要来渲染表单。
FormService： Activiti 中的流程和状态 Task 均可以关联业务相关的数据。通过使用 Form Service 可以存取启动和完成任务所需的表单数据并且根据需要来渲染表单。

三、java封装实例

1、前端界面效果图

2、二次开发类图

3、代码展示

　　如下是具体实现的类信息，当前实例封装的是通过具体人和人员角色两个维度来实现业务节点审核，要实现业务功能只需要实现BaseBusinessActivitiOption类的方法，并扩充业务实现就好。

4、使用总结

　　activiti的使用灵活多变，activiti自身有提供配置审核流的界面，经常很难融合与我们自己的产品设计中，所以需要我们按照自己的需求进行二次实现，

　　当然首当其冲需要解决的问题就是，界面的配置信息应放在怎样的一个载体中，再次就是如何有效的表达审核流的信息使能够生产一个满足业务需求的审核流；

　　最后就是这些载体信息如何转化为activiti需要的BPMN文件，并且如何反向解析回显配置。

　　以上这些问题是实现二次开发的最基础也是最重要需要考虑和解决的问题，至于其他的细节就需要在实现的过程中逐步去克服和处理了。
