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.
As shown in fig. 1, in an embodiment, a configuration updating method is provided, where the configuration updating method specifically includes the following steps:
and 102, receiving reminding information which is sent by the configuration center and is related to the update of the target configuration data item.
The configuration center is a server side for storing configuration data, wherein a Zookeeper file system is deployed for managing the configuration data and storing the configuration data in different nodes, and the different nodes correspond to different configuration data items.
The client registers and monitors the nodes concerned by the client, and the Zookeeper informs the client when the configuration data items on the nodes are added, changed or deleted. Therefore, it can be understood that the target configuration data item is a configuration data item concerned by the client, and the target configuration data item is kept concerned by registering and monitoring the corresponding node. When the target configuration data item is updated, the configuration center sends reminding information related to the update of the target configuration data item to the client.
In one embodiment, the configuration center sets different configuration authorities according to the project attribution of the nodes, and the client can only register and monitor the nodes and the sharing nodes of the same project.
And step 104, determining a monitoring node corresponding to the target configuration data item according to the reminding information, wherein the monitoring node is a node which is registered and monitored by the current client.
The reminding message is a message for reminding the client of updating a target configuration data item concerned by the client through the configuration center, and comprises node information corresponding to the target configuration data item, namely a node which is registered and monitored by the current client.
And 106, downloading the updated target configuration data from the monitoring node, and updating the configuration according to the target configuration data.
After receiving the reminding message, the client directly finds the monitoring node of the updated target configuration data item, downloads the updated target configuration data therein and updates the target configuration data. Different from the general method that after the information that the target configuration data item is updated is received, the full configuration data sent by the configuration center through the nodes is directly received, but the configuration data concerned by part of the client side is directly downloaded from the corresponding monitoring nodes of the target configuration data item, so that the method is more efficient.
The configuration updating method comprises the steps of firstly receiving reminding information which is sent by a configuration center and is related to the updating of a target configuration data item; determining a monitoring node corresponding to the target configuration data item according to the reminding information, wherein the monitoring node is a node which is registered and monitored by the current client; and downloading the updated target configuration data from the monitoring node, and updating the configuration according to the target configuration data. According to the invention, only the prompt for updating the target configuration data item is received through the connection relation with the configuration center, so that the target configuration data is downloaded and updated, resource waste and long synchronization time caused by full downloading of the updated configuration file are avoided, and configuration updating is efficiently completed.
In one embodiment, prior to receiving the alert message, the method further comprises: and establishing long connection with the configuration center in a heartbeat keep-alive mode, and sending the target configuration data item and the monitoring node to the configuration center so that the configuration center sends the reminding information according to the target configuration data item and the monitoring node, wherein the heartbeat keep-alive mode is used for periodically confirming the effectiveness of the long connection.
The long connection is a connection mode that the client and the server are not disconnected after establishing connection, and messages are sent and received until one party actively closes the connection, and the long connection is widely applied to monitoring systems and push services. It is important to maintain the availability of the long connection in a service scenario using the long connection, for example, the availability of the long connection cannot be maintained well, and in the case of frequent failure, the efficiency is not as high as that of other connection modes such as the short connection.
Therefore, the effectiveness of the long connection is determined by adopting a heartbeat keep-alive mode, and the method specifically comprises the following steps: and the client sends a heartbeat data packet or a heartbeat instruction to the server at intervals so as to judge whether the connection mode is alive or not, and if the receiving timeout of the heartbeat data packet or the heartbeat instruction is detected, reconnection operation is carried out.
After the client establishes long connection with the server, the target configuration data item and the corresponding monitoring node are sent to the configuration center to inform the configuration center, and when the configuration data corresponding to the node monitored by the client is changed, the client is informed to download the updated configuration data to the corresponding node. The above functions are realized by a corresponding SDK (Software Development Kit).
In another embodiment, after the client establishes long connection with the server, when the target configuration data item of the client is updated, the server only sends a prompt to the client which registers and monitors the corresponding node, and does not broadcast in the broadcast domain; the client only receives the updated configuration data of the corresponding node.
In one embodiment, performing registration listening for the node includes: and defining an initialization function according to the configuration data item corresponding to the node while registering and monitoring the node, wherein the initialization function is used for initializing the data module corresponding to the configuration data item after downloading the update data of the configuration data item.
Before updating the configuration data item, the corresponding data module needs to be initialized, and for some large-scale system-level items, the content needing to be initialized is particularly large, and the time consumption is long. In the invention, only the concerned configuration data items are updated, so that only the data modules of the part of the configuration data items need to be initialized.
The specific execution content of the initialization function corresponds to the configuration data type in the node, and if the mysql database configuration is updated, the execution content of the initialization function is to initialize the database connection pool; if the update is redis, the execution content of the initialization function is to initialize the client function of the redis.
In one embodiment, the updating the configuration according to the target configuration data includes: deserializing the target configuration data into a memory, wherein deserializing is converting character string data into objects; and executing the initialization function, calling the target configuration data from the memory for reloading, and finishing the configuration hot update of the current client.
After downloading of the target configuration data is completed, deserializing the target configuration data from the character string data into a structural object, and storing the structural object in a memory, so that a client can conveniently and directly call the structural object from the memory when performing hot update; in a general method, target configuration data is stored in a local disk, and related files need to be read when calling and updating are performed, so that disk IO (input/output) is busy, and a certain influence is caused on a CPU (central processing unit) and a memory. Therefore, the invention adopts the deserialization means to store the target configuration data into the memory, and is more convenient and efficient in calling.
After the initialization function is executed to initialize the data module corresponding to the target configuration data, the updated target configuration data is directly loaded to complete hot updating; the general configuration updating method usually needs to restart or redeploy the application service, and more or less influences the normal use of the application service, such as any abnormal interruption being processed, and the like.
In one embodiment, the deserializing the updated target configuration data into the memory includes: and analyzing the target configuration data from JSON character string data into a dictionary data structure object, and storing the dictionary data structure object into a memory, wherein the JSON is a data format, and the dictionary is an abstract data type.
Specifically, the target configuration data is analyzed from JSON character string data into a dictionary data structure object, the memory occupation is smaller after the target configuration data is converted into the dictionary data structure object, the time consumption of calling and accessing is smaller, and the method is more efficient and convenient.
In one embodiment, after the configuration update is completed, the method further comprises: and backing up the target configuration data to a local disk so that a backup file can be read from the local disk when the target configuration data in the memory is lost.
After the target configuration data is downloaded, a backup file is copied and stored in the local disk, so that the target configuration data deserialized into the memory is prevented from being lost due to unexpected restart, and the backup file can be read from the local disk at the moment.

a receiving module 10, configured to receive a notification message sent by a configuration center and related to update of a target configuration data item;
a determining module 20, configured to determine, according to the reminding information, a monitoring node corresponding to the target configuration data item, where the monitoring node is a node that has been registered and monitored by the current client;
and the updating module 30 is configured to download the updated target configuration data from the monitoring node, and perform configuration updating according to the target configuration data.
As shown in fig. 3, in one embodiment, the apparatus further comprises:
and the connection module 40 is configured to establish a long connection with the configuration center in a heartbeat keep-alive manner, and send the target configuration data item and the monitoring node to the configuration center, so that the configuration center sends the reminding information according to the target configuration data item and the monitoring node, where the heartbeat keep-alive manner is used to periodically confirm validity of the long connection.
In one embodiment, performing registration listening for the node includes: and defining an initialization function according to the configuration data item corresponding to the node while registering and monitoring the node, wherein the initialization function is used for initializing the data module corresponding to the configuration data item after downloading the update data of the configuration data item.
In one embodiment, the updating the configuration according to the target configuration data includes: deserializing the target configuration data into a memory, wherein deserializing is converting character string data into objects; and executing the initialization function, calling the target configuration data from the memory for reloading, and finishing the configuration hot update of the current client.
