BPMN-based micro-service workflow deployment method

Abstract

The invention discloses a BPMN-based micro-service workflow deployment method, and relates to the field of workflow engines, and the method specifically comprises the steps of enabling a user to connect all primitives in series through a flow editing interface, store the primitives in a bpmn format, screen each element of each primitive, and divide the elements into node elements and relation elements; for each element in each node class, removing a variable name id and a variable name value, and writing the remaining variable names and the remaining variable names into an array object template in the YAML; meanwhile, for each element in each relationship class, obtaining an execution sequence of the workflow according to variable values in variable names start and end, and writing the execution sequence into an array object dependences in the YAML; submitting the YAML file added with the declaration information to a workflow deployment engine, and for the current micro-service, reading the object class DAG by the engine to obtain a sequential execution sequence of elements; searching for corresponding elements in the object class Templates, and after all the elements are executedin sequence, finishing executing the micro-service of the node class; according to the invention, the threshold of micro-service deployment is greatly reduced.

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.
