Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In a first aspect, an embodiment of the present invention provides a data sharing method based on service chain coordination.
In an embodiment, referring to fig. 1, fig. 1 is a flowchart illustrating a data sharing method based on service chain coordination according to an embodiment of the present invention. As shown in fig. 1, the data sharing method based on service chain coordination includes:
step S10, receiving data sent by a data provider, pushing the data to a data writing queue, and writing the data in the data writing queue into a memory;
in this embodiment, if the data of the service system a is subscribed by other service systems, the service system a is used as a data provider, and the other service systems subscribing to the data of the service system a are used as data consumers. The execution subject of the scheme of the embodiment is the server. The data sent by the data provider is received through the server, the data comprises basic data, user data and the like, the data is pushed to the data writing queue, and then the data written in the queue is written in the memory.
Step S20, receiving a subscription request sent by a data consumer, obtaining target data corresponding to the subscription request from a memory, and pushing the target data to a data reading queue for the data consumer to read the target data from the data reading queue.
In this embodiment, the server receives a subscription request sent by the data consumer, and the target data required by the data consumer can be determined through the subscription request. For example, the data consumer is a service system B, the server determines that target data required by the service system B is user data of the service system a according to a subscription request sent by the service system B, obtains the target data corresponding to the subscription request, for example, the user data of the service system a, from the memory, and then pushes the target data to the data reading queue, so that the data consumer can read the target data from the data reading queue. It should be noted that the target data corresponding to the subscription request is set according to actual needs. Thus, the data of the service system A can be shared to the service system B.
Further, in an embodiment, the data provider and the data consumer are different business systems in the same platform.
In this embodiment, if the service system a and the service system B in the same platform and the data of the service system a is subscribed by the service system B, the service system a is a data provider and the service system B is a data consumer.
In the embodiment, data sent by a data provider is received, the data is pushed to a data writing queue, and the data in the data writing queue is written into a memory; receiving a subscription request sent by a data consumer, acquiring target data corresponding to the subscription request from a memory, and pushing the target data to a data reading queue for the data consumer to read the target data from the data reading queue. By the embodiment, the data of the data provider can be shared to the data consumer, and data sharing among different service systems is realized.
Further, in an embodiment, after step S20, the method further includes:
step S30, when the data of the data provider is monitored to change, a change reminding message is generated;
in this embodiment, when the data of the data provider needs to be changed, the data stored in the memory is changed through the corresponding instruction, when the change is completed, the server monitors that the data of the data provider stored in the memory changes, and generates a change reminding message according to the change.
Further, in one embodiment, step S30 includes:
when the data of a data provider is monitored to change, detecting whether a data consumer subscribing the changed data exists;
and if so, generating a change reminding message.
In this embodiment, it is considered that the changed data may not be subscribed by other service systems, that is, there is no data consumer, and it is not necessary to generate a change notification packet. Therefore, when the data of the data provider is monitored to change, whether a data consumer subscribing the changed data exists is detected, and only when the data consumer subscribing the changed data exists, a change reminding message is generated so as to send the change reminding message to the data consumer subscribing the changed data. Wherein, the data change includes but is not limited to: adding data, modifying data, and deleting data.
And step S40, sending the change reminding message to a data consumer.
In this embodiment, the change reminding message is sent to the data consumer, so that the data consumer can synchronously update the data of the data provider recorded at the local end according to the change reminding message, and consistency of the data at the two ends is ensured.
Further, in one embodiment, step S40 includes:
and sending the change reminding message to a data consumer subscribing the changed data.
In this embodiment, the data consumer that subscribes to the changed data is determined first, and then the change reminding message is sent to the data consumer that subscribes to the changed data.
Further, in one embodiment, a publish schema and a subscribe schema are provided. The resource aggregation and exchange service (server) follows the metadata specification and the data exchange specification, mainly providing centralized access and management of applications. The publishing mode is applicable to the data provider (platform subsystems or third party applications). When service data (such as user information, resource information and the like) of a data provider changes (is newly added, modified or deleted), an agent program assembles monitored data change information and change types into a message according to message specifications and sends the message to a data queue special channel of a resource convergence and exchange service, for example, the user information of a service system A is subscribed and shared by a service system B, the message comprises user information such as a user id, a user name and a user affiliated mechanism, when the user information of the service system A changes, the resource convergence and exchange service receives the message, checks a message format and analyzes the message, and pushes the checked data to a data consumer. The subscription mode is applicable to data consumers. The data consumer subscribes the required data through the resource aggregation and exchange service, and when the subscribed data is monitored to be changed, a corresponding message is generated according to the message specification and is sent to the data subscriber. After receiving the message, the data subscriber can consume the message and complete the data update of the database of the data subscriber. The data providing direction resource aggregation and exchange service submits a data exchange release application, generates a corresponding message, pushes data into a data queue and puts the data into a storage. And the data consuming side submits a subscription application to the resource gathering and exchanging service, calls the subscription API + service code, retrieves the data queue according to the subscription rule and returns a corresponding data message to the data consuming side.
In a second aspect, an embodiment of the present invention further provides a data sharing apparatus based on service chain coordination.
In an embodiment, referring to fig. 2, fig. 2 is a functional module diagram of an embodiment of a data sharing device based on service chain coordination according to the present invention. As shown in fig. 2, the data sharing apparatus based on service chain cooperation includes:
the write-in module 10 is configured to receive data sent by a data provider, push the data to a data write-in queue, and write data in the data write-in queue into a memory;
the sharing module 20 is configured to receive a subscription request sent by a data consumer, acquire target data corresponding to the subscription request from a memory, and push the target data to a data reading queue, so that the data consumer reads the target data from the data reading queue.
Further, in an embodiment, the data sharing apparatus based on service chain coordination further includes a change reminding module, configured to:
when the data of the data provider is monitored to change, generating a change reminding message;
and sending the change reminding message to a data consumer.
