A bpmn-based microservice workflow deployment method

Abstract

The invention discloses a BPMN-based micro-service workflow deployment method, which relates to the field of workflow engines, specifically: the user connects each graphic element through the process editing interface, stores it in bpmn format, and then screens each graphic element Elements, which are divided into node-type elements and relationship-type elements; for each element in each node type, remove the variable name id and value, and write the remaining variable name and value into the array object template in YAML; at the same time, for each Each element in a relationship class, according to the variable values ​​in the variable names start and end, obtains the execution sequence of the workflow, and writes it into the array object dependencies in YAML; submit the YAML file with added declaration information to the workflow deployment engine , for the current microservice, the engine reads the object class DAG to obtain the execution order of the elements; and searches for the corresponding elements in the object class Templates, and after executing all the elements in order, the execution of the node class microservice is completed; the present invention Greatly lowers the threshold for microservice deployment.

Description

technical field [0001] The invention relates to the field of microservice workflow engines, in particular to a BPMN-based microservice workflow deployment method. Background technique [0002] With the continuous development of Internet business, the subsequent increase in the number of users, the increase in the number of systems, and the more complex call dependencies, the system architecture has migrated from the single-body era to the service SOA era. Microservice is the product of SOA. This architecture advocates dividing applications into a group of small services. Each service runs independently in its own process. Services communicate with each other using lightweight communication mechanisms. Each Services are built around specific businesses. [0003] With the popularity and development of microservices, container technology has also been paid attention to accordingly. The container contains a complete runtime environment: in addition to the application itself, a...

Problems solved by technology

The existing algorithms are directly converted from XML language to YAML, and the elements embodied in the form of tags in XML are converted into indented expressions in YAML, and there is no conversion specifically for the BPMN specification.

Moreover, the existing technology does not analyze, filter and integrate the information in BPMN, but simply converts the format. The YAML file obtained in this way not only contains a lot of redundant information, but also cannot meet the needs of the deployment system.
