First embodiment
Fig. 1 is a schematic diagram of a technical architecture of a single number generation method according to a first embodiment. As shown in fig. 1, Maven is a project management and integration tool, which uses a standard directory structure and a default construction life cycle, and a Maven private warehouse is used for acting a remote warehouse and deploying a third-party component, and after the private warehouse is built, when Maven needs to download a component, the Maven directly requests the private warehouse, and if the private warehouse exists, the Maven downloads the component to a local warehouse, otherwise, the Maven requests an external remote warehouse, downloads the component to the private warehouse, and then provides the component to the local warehouse for downloading. And (2) packaging (a sequence-num-generator, a serial number generator) to a Maven private warehouse through Gitlab in a spring boot startup mode.
The functions of the implementation (sequence-num-generator) include generating a unique single number, requesting and maintaining a machine number from the zookeeper, and periodically sending a heartbeat to the zookeeper to maintain the relationship between the current container and the machine number. All the spring group micro-services can be directly introduced into the algorithm implementation in a spring boot startup mode, and relevant zookeeper addresses and service names are configured, and the micro-services can acquire the unique single number by means of the implementation only by introducing one algorithm class.
The PAAS Platform (Platform-as-a-Service) is used for providing cloud components for software, the cloud components are mainly used for application programs, the PAAS can realize a Maven warehouse management function through specific components, and a jar package is uploaded through a Maven warehouse to construct a java application.
The Zookeeper service cluster is used for providing coordination service for the distributed application program of the user, and the service A and the service B running in the PAAS platform can create corresponding temporary node service A and service B in the Zookeeper service cluster.
Through the framework, the unique single number can be generated by combining the java language with the zookeeper distributed temporary node function, the framework is simple, the realization is easy, and the development cost is low. The following describes a specific process of the single number generation method based on the above technical architecture.
Fig. 2 is a flowchart illustrating a single number generation method according to the first embodiment. Referring to fig. 2, the method for generating a single number of the present embodiment includes:
and step 130, the server generates a single number according to the machine number.
The order service, the transaction service or any other scene needing unique recording can use a single number, and the single number comprises a fixed number field, a current timestamp number field, a machine number field and a self-increment serial number field. In this embodiment, the single number is represented by 64-bit binary digits, wherein the 1 st bit is a fixed number field and is fixed to 0, so as to avoid the single number being a negative number; the 2 nd bit to the 42 th bit are the current time stamp digital field, and the unit is millisecond; the 43 rd to 52 th bits are machine number fields, the machine number is used for identifying each container in a single service, the single service supports 1024 micro-service containers at most, and the generation and management of the machine number are completed by a zookeeper service; bits 53 through 64 are incrementing sequence number fields, and a single micro service container can support 4096 incrementing sequence numbers per millisecond. Thus, a single microservice container can support 4096000 unique single number generations per second, with unique single number generation being implemented by a unified SDK and reused for different business services, the services being distributed services and/or microservices.
Referring to fig. 3, the process of generating a machine number and creating a corresponding temporary node by the Zookeeper service cluster may include:
the Zookeeper service cluster generates a machine number and judges whether the machine number exists or not;
if not, creating a corresponding temporary node;
if yes, judging whether the machine numbers are completely distributed;
if not, returning a result of failed creation, and executing a Zookeeper service cluster to generate a machine number and judging whether the machine number exists or not when the server side applies for the machine again;
if the allocation is finished, the result that all the machine numbers are allocated is returned.
After the server generates the single number according to the machine number, the method further comprises the following steps:
during the service operation, the server side sends heartbeat to the Zookeeper service cluster at regular time so as to determine that the machine number of the service is still used;
and when the Zookeeper service cluster does not receive the heartbeat sent by the server within the preset time length, clearing the machine number of the corresponding service.
The method comprises the steps of managing machine numbers by using a zookeeper temporary node, applying for the machine numbers (from 1 to 1024) when the service is started each time, trying to create the temporary node by the zookeeper according to the machine numbers, creating the temporary node if the machine numbers do not exist, and returning a result of failed creation to a server if the machine numbers exist. The server side receives the result of successful creation, and then the server side can generate the single number according to the machine number, so that the globally unique generation function of the single number is realized, and the server side can apply for the machine number circularly until the machine number is successfully applied or is full. After a single number is generated, the service sends heartbeat to the zookeeper at regular time to determine that the machine number of the service is still used, and when the service loses the heartbeat due to downtime, restart or reissue for various reasons, the zookeeper can clear the machine number losing the heartbeat for recycling. In this way, the single service multi-micro service container can be ensured to correctly generate a unique single number and be globally unique.
In the method for generating the single number, when the server starts the service, the server applies for the machine number of the service to the Zookeeper service cluster; responding to the application, the Zookeeper service cluster generates a machine number, creates a corresponding temporary node and sends the machine number to the server; and the server generates a single number according to the machine number. Through the mode, the zookeeper temporary node can be used for managing the machine number, and the machine number is prevented from being repeated based on the distributed coordination capacity of the zookeeper, so that the single number is prevented from being repeated.

The single number is represented by 64-bit binary digits, wherein the 1 st bit is a fixed number field and is fixed to 0, the 2 nd bit to the 42 th bit are current timestamp digit fields, the 43 rd bit to the 52 th bit are machine number digit fields, and the 53 th bit to the 64 th bit are self-increasing serial number digit fields.
