本发明涉及一种基于微服务SaaS的企业级工作流引擎实现方法及系统，属于业务数据处理技术领域。The invention relates to an enterprise-level workflow engine implementation method and system based on micro-service SaaS, and belongs to the technical field of business data processing.
背景技术Background technique
随着业务的发展，采用传统本地部署软件的企业往往跟不上企业的发展速度和战略变化。本地部署存在运维成本高，升级困难，个性化需求难以及时满足等问题。于是，SaaS平台应运而生，软件即服务，供应商统一将软件部署在云服务器上统一运维，客户只需缴纳一定的订阅费即可使用服务，并可灵活购买扩展服务，定制化开发。而企业信息审批流程化，也是企业发展的必经之路，OA系统，财务系统几乎绝大多数业务复杂的系统都需要工作流引擎来打通人工审批和系统自动化。As the business grows, enterprises that use traditional on-premises software often cannot keep up with the pace of development and strategic changes. Local deployment has problems such as high operation and maintenance costs, difficult upgrades, and difficulty in meeting individual requirements in a timely manner. As a result, the SaaS platform came into being, software as a service, and suppliers deployed software on cloud servers for unified operation and maintenance. Customers only need to pay a certain subscription fee to use the service, and they can flexibly purchase extended services for customized development. The process of enterprise information approval is also the only way for enterprise development. OA systems, financial systems, and almost most systems with complex business require a workflow engine to get through manual approval and system automation.
传统的工作流引擎一般分为内置和外置，内置即直接将工作流引擎集成到某一业务系统中，比如OA系统的工作流引擎，它直接与OA系统耦合在一起，灵活性不足，适用面也很窄。外置工作流引擎则一般是独立部署的，作为第三方系统与各个系统打通。现有的主流使用的业务系统中需要接入审批流程，通常是一个场景接入审批流就需要做一个复杂的流程设计。每个场景的审批内容不同，提交给审批人审核查看的表单内容是变化的，导致审核详情页面也不同。因此，目前业务系统的业务审批处理，需要由专业的审批人员人工对待审批的业务请求进行核实确认，最后作出对应决策，审批效率低，而且业务审批处理受审批人员个人因素影响大，审批决策的准确度有限。The traditional workflow engine is generally divided into built-in and external. The built-in directly integrates the workflow engine into a certain business system, such as the workflow engine of the OA system, which is directly coupled with the OA system and lacks flexibility. The face is also very narrow. The external workflow engine is generally deployed independently, and is connected with each system as a third-party system. The existing mainstream business system needs to be connected to the approval process. Usually, a scenario needs to be connected to the approval flow and requires a complex process design. The approval content of each scenario is different, and the content of the form submitted to the approver for review and viewing changes, resulting in different review details pages. Therefore, the current business approval processing of the business system requires professional approvers to manually verify and confirm the approved business requests, and finally make corresponding decisions. The approval efficiency is low, and the business approval processing is greatly affected by the personal factors of the approvers. Accuracy is limited.

实施例1Example 1
参见图1和图2，本发明实施例1提供一种基于微服务SaaS的企业级工作流引擎实现方法，包括：Referring to FIG. 1 and FIG. 2,
S1、通过在线流程设计器进行流程定义，根据BPMN2.0协议增加扩展节点存储自定义的业务化配置，业务化配置包括审批规则、审批方式、跳转条件和服务调用；S1. Define the process through the online process designer, and add an extension node according to the BPMN2.0 protocol to store the customized business configuration. The business configuration includes approval rules, approval methods, jump conditions and service calls;
S2、预先进行流程表单定义，流程表单包括只读表单和可编辑表单，通过流程表单在审批时展示业务单据详情；S2. Define the process form in advance. The process form includes a read-only form and an editable form, and the business document details are displayed during approval through the process form;
S3、通过审批规则在人工节点查找审批人员，通过审批方式判断在是否满足指定条件时离开当前人工节点继续向下流转，通过跳转条件控制流程分支走向，通过服务调用在指定节点远程调用业务模块执行自定义逻辑。S3. Find the approver at the artificial node through the approval rule, judge whether the specified condition is met by the approval method, and leave the current artificial node and continue to flow downward, control the direction of the process branch through the jump condition, and remotely call the business module at the specified node through the service call Execute custom logic.
本实施中，基于Activiti官方标准在线流程设计器，针对业务场景定制化流程功能配置，扩展BPMN2.0协议，增加扩展节点，存储自定义的业务化配置，包含审批规则、审批方式、跳转条件和服务调用等配置。可基于BPMN2.0协议流程的导入导出，从而实现流程多环境、多系统迁移，即“一次配置，到处使用”，客户在使用SaaS平台时，可以直接在线配置或导入已有流程图。In this implementation, based on Activiti's official standard online process designer, the process function configuration is customized for business scenarios, the BPMN2.0 protocol is extended, extension nodes are added, and the customized business configuration is stored, including approval rules, approval methods, and jump conditions. and configuration of service calls. It can be based on the import and export of BPMN2.0 protocol process, so as to realize multi-environment and multi-system migration of process, that is, "configure once, use everywhere", when customers use the SaaS platform, they can directly configure or import existing flowcharts online.
具体的，Activiti是一个独立运作和经营的开源项目品牌，是一种轻量级，可嵌入的BPM引擎，而且还设计适用于可扩展的云架构。Activiti提供宽松的Apache许可2.0，以便这个项目可以广泛被使用，同时促进Activiti BPM引擎和BPMN 2.0的匹配。BPMN2.0较BPMN1.x而言，定义了流程的元模型和执行语义，即BPMN2.0解决了存储、交换和执行的问题。Specifically, Activiti is an independently operated and operated open source project brand, a lightweight, embeddable BPM engine, but also designed for scalable cloud architectures. Activiti provides the permissive Apache License 2.0 so that this project can be widely used, while facilitating the matching of the Activiti BPM engine and BPMN 2.0. Compared with BPMN1.x, BPMN2.0 defines the meta-model and execution semantics of the process, that is, BPMN2.0 solves the problems of storage, exchange and execution.
本实施例中，只读表单通过iframe实现，可编辑表单通过动态路由和异步加载实现跨模块加载页面。流程表单的定义包含表单对应的前端路由；在设计流程图过程，对任意人工节点配置审批表单，将审批表单编码存储到当前节点；在审批过程，依据表单编码和流程变量动态解析表单地址。In this embodiment, the read-only form is implemented by iframe, and the editable form is implemented by dynamic routing and asynchronous loading to load pages across modules. The definition of the process form includes the front-end route corresponding to the form; in the process of designing the flowchart, configure the approval form for any artificial node, and store the approval form code to the current node; in the approval process, dynamically resolve the form address according to the form code and process variables.
具体的，流程表单用于在审批时展示业务单据详情。包括只读表单和可编辑表单两种类型。只读表单基于iframe实现，可编辑表单基于动态路由加上异步加载实现跨模块加载页面。通过预先定义流程表单，主要包含表单对应的前端路由。在设计流程图时，可针对任意人工节点配置审批表单，将审批表单编码存储到当前节点。在审批时，工作流引擎依据表单编码和流程变量动态解析表单地址，可实现在不修改流程定义的前提下更改表单。Specifically, the process form is used to display the details of business documents during approval. There are two types: read-only forms and editable forms. Read-only forms are implemented based on iframes, and editable forms are based on dynamic routing plus asynchronous loading to load pages across modules. By pre-defining the process form, it mainly includes the front-end routing corresponding to the form. When designing a flowchart, an approval form can be configured for any artificial node, and the approval form code can be stored in the current node. During approval, the workflow engine dynamically parses the form address according to the form code and process variables, so that the form can be changed without modifying the process definition.
具体的，iframe是HTML标签，作用是文档中的文档，或者浮动的框架。iframe元素会创建包含另外一个文档的内联框架(即行内框架)。Specifically, an iframe is an HTML tag that acts as a document within a document, or a floating frame. The iframe element creates an inline frame (ie, an inline frame) that contains another document.
本实施例中，可以将审批规则、审批方式、跳转条件、服务调用四种控制流程走向的业务控制统一抽象为服务任务。通过事先定义，客户可直接在流程设计中选择以上高阶配置来实现更复杂的流程走向。In this embodiment, the business control of the four control process trends, including the approval rule, the approval method, the jump condition, and the service invocation, can be abstracted into a service task. By defining in advance, customers can directly select the above high-level configurations in the process design to realize more complex process trends.
以上审批规则、审批方式、跳转条件、服务调用支持远程调用、表达式等方式。远程调用基于Rest Template进行调用，表达式基于odyssus实现表达式解析。The above approval rules, approval methods, jump conditions, and service calls support remote calls and expressions. The remote call is based on Rest Template, and the expression is based on odyssus to implement expression parsing.

具体的，工作流引擎以当前待办实例作为父类创建子类待办实例，同时重置父类的审批人为指定类型，该类型依据加签类型决定，并设置子类的管理者为父类的审批人，即当前审批人，创建子类的数量取决于审批人加签人数量。子类完成审批后，查询其父类并对其进行处理，具体的处理需依据父类的加签类型进行处理，前加签需将审批人重置为原始审批人后直接返回，后加签则需在前加签的基础上将其审批完成。Specifically, the workflow engine uses the current to-do instance as the parent class to create a sub-class to-do instance, and at the same time resets the approver of the parent class to the specified type, which is determined according to the signature type, and sets the manager of the sub-class as the parent class The number of approved approvers, that is, the current approver, depends on the number of approvers who sign up. After the subclass completes the approval, query its parent class and process it. The specific processing needs to be processed according to the signature type of the parent class. Before adding a signature, you need to reset the approver to the original approver and return directly, and then add a signature. It needs to be approved on the basis of the previous signature.
工作流引擎依据当前审批人获取其最近一次审批过的节点(非流程当前节点)，删除当前节点的所有待办实例，最后将当前流程回溯到指定节点。The workflow engine obtains the last approved node (not the current node of the process) according to the current approver, deletes all to-do instances of the current node, and finally traces the current process back to the specified node.

具体的，针对相同分类下的流程定义(使用同一类型业务单据)，通过预先配置业务参数组(参见表1)，指定不同的业务参数组关联不同的流程定义，以达到启动工作流时，通过业务参数动态选择流程定义并启动工作流。Specifically, for the process definitions under the same category (using the same type of business documents), pre-configure business parameter groups (see Table 1), and specify different business parameter groups to associate with different process definitions, so that when the workflow is started, the Business parameters dynamically select process definitions and initiate workflows.
某笔单据参数与流程A、B、C、D匹配，由于流程A字段值匹配值最多，选择流程A；若存在与流程A不匹配数据时，但与流程B、C、D匹配且匹配的参数数量相同，由于变量【公司】较【业务实体】靠前，因而从流程B、D选择，流程B、D两个优先级均一致，所以随机选择一条；流程E的变量值均为空，为默认流程，其优先级最低，当以上均未匹配时，选择该流程。The parameters of a document match processes A, B, C, and D. Since the field value of process A has the most matching values, process A is selected; if there is data that does not match process A, it matches and matches processes B, C, and D. The number of parameters is the same. Since the variable [company] is higher than [business entity], it is selected from processes B and D. Both processes B and D have the same priority, so one is randomly selected; the variable value of process E is empty, It is the default process with the lowest priority. When none of the above matches, this process is selected.
