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.
The microservice architecture is a computer architecture that disassembles system functionality into individual sub-services. Each microservice is a minimal unit of application management, and applications can be independently developed, designed, and released. Configuration hot-update means that the configuration information is validated in real time without restarting the server when the configuration information is modified. There are two main ways to implement configuration hot update currently: one way is to store the configuration as a record in a relational database such as Mysql or a NoSql database such as Mongodb, and update the record to realize the hot update of the configuration. Although the configuration is stored in the database as a record in this way, the application in the cluster can actively obtain the dynamic change information of the configuration by initiating a request, but the method has high code intrusiveness and no expandability. Meanwhile, the application needs to actively initiate a request every time the application uses the configuration, and the network return delay generated under high concurrency has influence on the system performance. The other mode is that the Spring Cloud is a complete microservice solution based on a Spring Boot framework, and is a configuration management mode for storing configuration file information based on Git, a configServer caches the configuration files, an application obtains configuration through a ConfigClient, and the configuration modification does not need to restart service. The distributed configuration center with SpringCloud can solve the problem of configuration hot update, but the webhook method relying on the publish subscription of RabbitMq or the git code warehouse is needed to push the change of the configuration center to the cluster service. And a flexible and easy-to-use configuration management platform is lacked to manage the configuration, so that the management cost is high.
Based on the above technical problem, this embodiment provides a method for updating configuration information under a micro service architecture, which can improve efficiency of obtaining configuration information, reduce information interaction between a server and a client, save network resource cost, and reduce operation and maintenance cost, specifically referring to fig. 1, where fig. 1 is a flowchart of a method for updating configuration information under a micro service architecture provided in this embodiment of the present application, and specifically includes:
s101, when the micro-service application is started, obtaining configuration information corresponding to the micro-service application from a server side, and storing the configuration information into a memory.

In this embodiment, the configuration information may be configuration information of a configuration item, or configuration information of a configuration file. In the embodiment, after the micro service is started, the required configuration information is acquired from the server, and then the configuration information is stored in the memory, so that information interaction between the client and the server can be reduced, the configuration information does not need to be acquired from the server every time the configuration is used, the possibility of information transmission is reduced, and network bandwidth resources are saved.
S102, when an updating instruction of the configuration information pushed by a target cluster of the server is received, a downloading request of the configuration information corresponding to the updating instruction is sent to the server.
The target cluster in this embodiment is deployed at the server, and the configuration information of the server is stored in the target cluster, when the configuration information of the server sends a change, the target cluster will push a change message, that is, an update instruction, to the client, and after receiving the update instruction, the client sends a download request of the configuration information corresponding to the update instruction to the server. The target cluster in this embodiment refers to a consul cluster or a zookeeper cluster; it can be understood that Consul is an open source tool developed by Go language, realizes service discovery and configuration of a distributed system, has the characteristics of being distributed and capable of being horizontally expanded, and provides functions of service discovery, monitoring and checking, key value pair storage, security service, multiple data centers, and the like. Zookeeper is a high-performance open-source distributed application coordination service. It provides simple primitive functionality based on which a distributed application can implement more advanced services such as synchronization, configuration management, cluster management, namespaces. When the configuration information of the server is sent and changed, the client only downloads the updated part of the configuration information from the server, and the rest of the configuration information is stored in the local memory, so that the client does not need to download all the configuration information, the efficiency of acquiring the configuration information can be effectively improved, the influence on the system can be reduced under the condition of high concurrent network delay, and the client can acquire the configuration information in time and respond to the microservice application. It should be understood that the embodiment does not limit the specific content of the update instruction, and may be a code or a communication protocol, as long as the client can be triggered to send a download request for obtaining the changed configuration information.
S103, receiving configuration information corresponding to the updating instruction sent by the server, and updating the configuration information in the current memory according to the configuration information corresponding to the updating instruction.
The embodiment does not limit the specific process of updating the current memory configuration information, and may be determined according to the specific content of the changed configuration information. For example, after receiving the changed configuration information sent by the server, that is, the configuration information corresponding to the update instruction, where the changed configuration information is the information of the configuration item, the configuration information of the configuration item may be added to the configuration information in the current memory; if the changed configuration information is the configuration information of a certain configuration file in the current memory, the changed configuration information can replace the configuration information of the corresponding configuration file in the current memory to realize updating.
In a specific embodiment, updating the configuration information in the current memory according to the configuration information corresponding to the update instruction may include:
and acquiring the affected object list from the resource attribute configurator, and updating the attribute value of the object list in the configuration information corresponding to the updating instruction.
In this embodiment, the client acquires the affected object list from the resource attribute configurator according to the acquired new configuration information, that is, the configuration information corresponding to the update instruction, and then updates the attribute value of the affected object list in the changed configuration information, so as to update the configuration information of the current memory.
In a specific embodiment, in order to ensure that the updated configuration information version is higher than the configuration information version of the current memory, before updating the configuration information in the current memory according to the configuration information corresponding to the update instruction, the method may further include:
judging whether the modification time of the configuration information corresponding to the updating instruction is greater than the modification time of the configuration information in the current memory;
and if so, executing the step of updating the configuration information in the current memory according to the configuration information corresponding to the updating instruction.
That is, in this embodiment, before updating the configuration information summarized in the current memory according to the configuration information corresponding to the update instruction, it is further determined whether the modification time of the changed configuration information is greater than the modification time of the configuration information in the current memory, that is, whether the version of the configuration information corresponding to the update instruction is newer than the version of the configuration information in the current memory, and if so, the operation of updating the configuration information in the current memory is executed. The updated configuration information version can be ensured to be updated, the micro-service application of the client side is better met, and the user experience is improved.
In a specific embodiment, in order to prevent the situation that the service cannot be used after the configuration information is changed, after the configuration information in the current memory is updated according to the configuration information corresponding to the update instruction, the method may further include:
and calling back and updating the service logic associated with the configuration information corresponding to the updating instruction.
That is, in this embodiment, after the configuration information in the current memory is updated, the service logic associated with the updated configuration information is also updated in a callback manner, so that the service associated with the changed configuration information can be updated in time, the service can be used normally, the situation that the service cannot be used after the configuration information is changed is prevented, the customer requirements can be better met, and the user experience is improved.
In a specific embodiment, in order to ensure stable operation of the client microservice application, the method may further include:
and when the target cluster of the server is unavailable, acquiring the configuration information backed up in the database of the server.
In this embodiment, when the target cluster of the server is unavailable, the configuration information backed up in the database of the server may be obtained, that is, when the target cluster is unavailable and the client cannot obtain the configuration information from the target cluster of the server, the server backs up the configuration information in the database and performs persistent configuration, and at this time, the client may obtain the backed-up configuration information from the database, thereby ensuring high availability of the configuration center of the server and ensuring stable operation of the microservice application of the client.
Based on the above embodiment, the configuration information is stored in the memory, when the update instruction of the configuration information pushed by the target cluster is received, the configuration information corresponding to the update instruction is only obtained from the server side, and all the configuration information does not need to be downloaded, so that the efficiency of obtaining the configuration information is improved, the configuration information is stored in the memory, and the configuration information does not need to be obtained from the server side every time the configuration is used, so that the information interaction between the server side and the client side is reduced, the network resource cost is saved, and the operation and maintenance cost is reduced.
A specific embodiment is provided below, where a consul cluster is selected as a target cluster, and the process includes an interaction process between a client and a server after the client is started. Fig. 2 is a system architecture diagram of a client and a server according to the present embodiment. The server is an independent service platform and provides capabilities of configuration management, configuration release, authority management and the like; the client is a component that provides for applications that need to support microservice configuration hot updates.
The client component can be composed of five functional modules, including a configuration initialization module, a configuration download module, a configuration monitoring module and a configuration hot update module, wherein the configuration hot update module is the most core function. The client startup process in this embodiment includes four steps:
1. scanning fields needing hot update comments in the microservice application and placing the fields into a memory;
2. downloading configuration information from a server console through an HTTP (hyper text transport protocol) and storing the configuration information in a memory;
3. a node is created on a Consul cluster according to each configuration data in a memory and monitored, once the data of the node is changed, a client receives an update instruction pushed by the Consul cluster, and the client triggers to download the changed configuration information, namely the configuration information corresponding to the update instruction, to a server so as to update the configuration information in the current memory;
4. and initializing and configuring a corresponding callback updating function.
The configuration updating process of the server side console can be divided into three steps:
1. the user updates the configuration information on the server console;
2. the server side console sends the updated configuration information to a corresponding node on the consul cluster, and the consul cluster informs the client side of the configuration change information, namely sends an update instruction to the client side;
3. and the server side sends the configuration information corresponding to the updating instruction to the client side.
Fig. 3 is a specific work flow diagram of information interaction between the client and the server according to this embodiment. The P1 configuration initialization process includes: creating configuration, scanning application, HTTP request downloading configuration, monitoring configuration, configuration pushing, callback updating and other processes.
P1S1, the establishment configuration is initiated by the micro-service operation and maintenance development, the operation server page establishes configuration information and makes the configuration persistent, and the initialization configuration is provided for the downstream micro-service startup to ensure that the downstream micro-service startup can be started normally;
P1S2, scanning the application after the micro service is started, and acquiring the required configuration information from the configuration center of the server;
P1S3, the client side sends an HTTP downloading request to the server side, and the downloading configuration information is stored to a designated folder in a file form;
the P1S4 and the server respond to the HTTP downloading request;
P1S5, creating nodes on the consul cluster by the client aiming at each configuration and registering the listener on the nodes;
P1S6, when the configuration information of the node is changed, pushing the node to the client in real time;
P1S7, the client side pushes the update instruction to the microservice;
P1S8, the configuration of the client for setting callback update processes the logic after callback.
The PS2 configuration change process is as follows:
the change of the P2S1 and the configuration information is initiated by micro-service operation and maintenance development or service responsible personnel, the configuration information is changed and the configuration is made persistent by operating the page of the service end;
the P2S2 and the server side operate the node state by using a consul API and inform the client side of the change of the node data in real time;
the P2S3 receives the change message, namely the update instruction;
P2S4, initiating an HTTP downloading request for changing information to a server, comparing modification time of two new and old files, namely configuration information corresponding to an updating instruction and configuration information in a current memory, and if the modification time of the new file is greater than the modification time of the old file, notifying a rewritten resource attribute configurator to acquire an affected attribute and an affected object list;
the P2S5 and the client update the attribute value corresponding to the affected object according to the changed configuration information;
P2S6, the configuration of the client for setting callback updates processes the logic after the callback.
Based on the above embodiments, the method for updating configuration information under the micro service architecture provided by the present application has the following performance: maintainability, which realizes centralized management of configuration information of different applications, different environments and different clusters under a micro service architecture; configuration hot update provides a method for pushing modified configuration information to the micro-service in real time without restarting the server configuration to take effect in real time, thereby greatly reducing the operation and maintenance cost; the authority management is realized, all the applications and the configurations increase the authority management and the auditing mechanism, and the possibility of artificial errors is reduced; version management, wherein all configurations of different environments, different applications and different clusters are subjected to version configuration, so that the configurations are convenient to rollback; the configuration among different versions provides a difference comparison function, so that the problems caused by configuration change can be conveniently and quickly checked; a client configuration thermal updating component and a server management and control platform are developed around the method, and the server is an independent micro-service platform and is used for configuration management, configuration release and authority management; the client is an infrastructure of each micro-service, and can realize the configured hot update only by configuring the component in the dependence file without intruding business codes; the configuration open platform opens the API capability of configuration management to the outside, and the heterogeneous system can be quickly accessed to the configuration center through the API.
Based on all the embodiments, the configuration real-time hot update is realized based on the consul cluster under the micro-service architecture, and the micro-service does not need to be restarted. The configuration information is published to the consul node through the server, and the micro-service dynamically acquires the configuration information as a subscriber, so that centralized management of configuration and dynamic update of configuration are realized. By updating the configuration information on the server-side distributed configuration center, the updating instruction can reach all micro-service applications in a broadcasting mode, and configuration hot updating can be realized during operation without repackaging and restarting the micro-service, so that the release cost is reduced; and the configuration hot update function can be realized only by adding a dependent item of the client component in the dependent configuration of the service code and configuring and uploading the dependent item to a distributed configuration center of the server, and the process of the application node in each cluster senses the configuration change. The service is separated from the configuration, the local configuration information is preferentially read, even if the server is unavailable, the client application can normally run, and the whole architecture is more stable. And the high availability of the configuration center is ensured by the server under the micro-service architecture through database persistent configuration.
