Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to the attached drawings of the specification, the invention provides a technical scheme that: a lightweight low-coupling working state change collection notification method comprises the following steps:
annotations, which contain two attributes, the attribute name of the object state and a notification event group;
a configuration file containing two configuration items, user information in a session and a general method of metadata;
a message queue for receiving changes and distribution of workflow status;
the workflow state change collection notification method based on the annotation plug-in mode comprises the following steps:
1) comparing the attribute names of the object states of the notification event groups in the annotations according to the user information in the configuration file, and triggering collection if the attribute names are the same;
2) and according to the general method of the metadata in the configuration file, determining the operation of the annotation method, determining the object state and the notification event group in the parameter extraction as the state addition or the state subtraction, and pushing the object state and the notification event group into a message queue.
The invention takes the collection/notification of the state change of the object in the workflow as an independent function outside the workflow engine, thereby being lighter and meeting different scenes; the information collection of the state change uses the tangent plane programming technique, reduce the invasion of the belt code, reduce and couple; and distributing the notice in a message queue mode for consumption of various channels (databases).
The invention is composed of 6 units of annotation, configuration file, parameter extraction, logic processing, exception capture and message queue.
And annotating: annotating the need to mark on the method (add, delete, or modify) that operates on the metadata to clarify the workflow object; the annotation has two attributes: attribute names of object states and notification event groups. The attribute name of the object state specifies the state of the metadata (namely the name of the parameter state transmitted by the metadata method), and whether to collect the metadata is determined according to the change of the state; the notification event contains 5 attributes: the operation object, the event, the notification object, the state addition and the state subtraction are summarized into a sentence, namely, a person needs to be notified to whom or withdraw from notification after the person does the event, and specific attributes such as limited time can be added to the notification event according to actual requirements. Wherein the operation object and the notification object can be in the form of a user, a role or an organization. Collecting
Configuration files: the configuration file is in the form of a key-value pair, and has a configuration item: a general method of metadata; common methods of metadata include add, delete, modify, and query methods.
Parameter extraction: the parameter extraction adopts the spring aop containing (@ Around) section programming technology, and the parameters are extracted and delivered to the logic processing unit for processing before the method is executed. The parameter extraction will extract two parameters: object status, notify object.
Logic processing: and extracting data in the three units from the annotation, the configuration file and the parameter for logic processing. The method comprises the following specific steps: 1) according to a general method of metadata in a configuration file, determining which operation (adding, deleting or modifying) is the annotation method, wherein the adding is status adding, the deleting is status subtracting, and the modifying has three conditions, namely status unchanged, status adding and status subtracting; 2) determine which case the state under modification is (constant, plus, minus): keeping the following steps: acquiring the state stored in the database by a metadata query method, wherein the state is unchanged if the state of the database is the same as the state transmitted in the parameters; adding: acquiring state addition and state subtraction in the annotated notification event group, wherein if the state addition is the same as the state of parameter transmission, the state addition is addition, and if the state subtraction is the same as the state of parameter transmission, the state subtraction is subtraction; 3) adding and subtracting the states obtained in the step (1) and the step (2), and pushing the states to a message queue, wherein the state adding is who the message is pushed to; a notification to whom the status was reduced to revocation; and if the state is not changed, pushing is not carried out.
Abnormal capture: and canceling the pushing to the message queue if an exception occurs after the metadata method marked by the annotation is executed.
Message queue: the message queue is responsible for receiving and distributing information.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
