It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Zookeeper is a sub-project of Hadoop, and is a coordination system in a distributed system, and the available services mainly include: configuration services, name services, distributed synchronization, group services, and the like.
The enterprise-level messaging platform includes: how to organize and manage the client and the parameter configuration is a key technology for solving a large-scale extended message platform.
The management of the message service side is the management of parameters needed for accessing the message service side. These parameters typically include the IP address and port of the server, the message queue name, the message exchange name, the client's reconnect policy, timeout parameter configuration, etc. These parameters are used for access by a client when accessing the message service.
The embodiment of the invention adopts the techniques of message servitization and parameter cataloging, supports the dynamic expansion of a message service cluster, shields the influence on the application, realizes the dynamic management of the message cluster and the real-time synchronization of the parameters, in addition, the real-time synchronous update of the message configuration information at a server and a client shields the influence of the change of the server on an access application system, realizes the real-time detection of the fault isolation and the recovery of the message service, and utilizes the message service load balance and the multi-machine room multi-activity deployment.
FIG. 1 is a schematic diagram of an application architecture according to an embodiment of the present invention; as shown in fig. 1, a message service cluster a and a message service cluster B for providing message services are used as message service terminals, and perform bidirectional interaction with zookeeper respectively, and a client 1 and a client 2 also perform bidirectional interaction with zookeeper, and in addition, a parameter cache region of the client also performs bidirectional interaction with zookeeper.
Fig. 2 is a first flowchart of a zookeeper-based message service access method in an embodiment of the present invention; as shown in fig. 2, the message service access method based on zookeeper is applied to a zookeeper device, and includes the following steps:
step S100: acquiring a configuration information change message sent by a server;
specifically, when the configuration information of the server is changed, the configuration information change message is actively issued to the zookeeper device, so that the zookeeper device can update.
In addition, the configuration information initially stored in the zookeeper device is also issued by the server according to the service configuration of the server.
Step S200: updating local configuration information according to the configuration information change message;
specifically, the configuration information change message includes: adding, deleting and modifying, and updating information by adopting different strategies according to different update messages.
Step S300: and sending the updated configuration information to the client registered with the corresponding watch monitor.
In particular, zookeeper provides a publish/subscribe functionality for distributed data implemented using a watch mechanism. zookeeper allows a client to register a watchdog, and when some event of a server triggers the watchdog, an event notification is sent to the client registered with the watchdog to realize the distributed notification function. The client establishes a parameter cache area to map parameter configuration. And monitoring the corresponding change events of addition, deletion and modification by using a watch, and synchronizing the data to a parameter cache region of the client in real time through a synchronization thread when the zookeeper is modified. The parameter cache area keeps consistent with zookeeper data as much as possible. The client accesses the parameter cache area through a uniform interface and judges whether the parameters change or not by self. For message sending and receiving, the judgment of whether the parameters change is carried out before the message sending or receiving is carried out each time, when the obtained new parameters are found to be inconsistent with the last parameters, the parameters need to be updated, and the message receiving or sending action is carried out after the message access environment is rebuilt if necessary.
By adopting the technical scheme, the watchdog monitoring mechanism of the zookeeper is utilized, and after the configuration information is updated, the updated configuration information is sent to the client registered with the corresponding watchdog monitoring in time, so that abnormal service is prevented.
In an optional embodiment, referring to fig. 3, the zookeeper-based message service access method further includes:
step S400: acquiring a message service code sent by the client;
in order to facilitate application configuration and shield a complex mechanism in a message platform, a server side allocates a message service code to each accessed client side in the embodiment of the invention. A message service code corresponds to a set of configurations, and a set of resources are served at the message service end correspondingly. One of the dynamic resources is the server address and port. In order to ensure high availability, a service code application has multiple groups of machines for providing message services, and the group of machines should also provide services for other message codes, so that one group of machines provides services for the message codes of one group, and the group of machines providing message services for the same group of service codes is called a message service cluster. A unique message service cluster is configured in one message service code. The application can obtain the addresses and ports of this group of service clusters when addressing using the message service code.
In addition, the configuration information of the service code includes the following:
service code: a message service code;
service name: the name of the message service code is generally named according to the message scenario, such as: changing events for public customer information;
service version: service version number, currently only 01;
a service component: message service cluster names, such as: MQP, this entry is to be consistent with the cluster name configured in the "address" entry below;
available state: available/unavailable, and when the identification is unavailable, the information of the service code cannot be downloaded;
and (3) transmitting service information: corresponding routing, queue and other information;
example name: only CN-domestic examples are supported at present in response to multi-example messages;
address: configuration of connection-related information for message services, such as: the connection address, the number of reconnections, and the failover mechanism are currently configured as url strings.
The configuration items of the service cluster are composed of the following items:
service component abbreviation: the English name of the message service cluster corresponds to the service component in the service code;
service component name: the Chinese name of the message service cluster;
the component security node: a secure node number of the message service;
the platform to which the component belongs: an application platform built correspondingly;
the communication protocol is as follows: communication protocols, which may support different communication protocols;
address: IP address and port information of the server;
step S500: and sending the configuration information corresponding to the message service code to the client.
The message service code and the zookeeper information are directly sent to the client by the server, and when the client needs to provide the message service by the server, the client firstly accesses the zookeeper according to the zookeeper information and sends the message service code to the zookeeper so as to acquire the configuration information corresponding to the message service code.
And the client accesses the corresponding server according to the configuration information to perform message service.
By adopting the technical scheme, the client can effectively access the server, and the normal operation of the message service is ensured.
In an optional embodiment, referring to fig. 4, the zookeeper-based message service access method further includes:
step S600: sending a detection message to the server;
at a message service end, when the service is started, the terminal registers in the zookeeper, and when the service is stopped, the terminal logs out the zookeeper. However, sometimes the server may not provide the service normally for some reason, the process is not stopped, and the service address in the zookeeper is not logged out, but the service is abnormal.
To solve this problem, a green light detection machine is established between the server and the zookeeper, when the green light service is unavailable, the address of the machine is logged out of the zookeeper, and when the green light service replies, the address is registered to the zookeeper.
Step S700: and if the message fed back by the server is not received within the preset time, the server is cancelled.
It should be noted that the client may obtain the address of the server through the cache mechanism, and meanwhile, the client may determine whether the address is changed, so as to determine whether to reestablish the message access environment such as connection. The connection establishment is time consuming, so when the message address changes, it should be compared which addresses are unchanged, which addresses are newly added, and which addresses are deleted, and different change strategies are adopted for the new addition, the unchanged addition and the deletion. For addresses that do not change, the connection does not need to be updated. And for the newly added address, establishing a new connection, updating the new connection into the available connection list, and for the deleted address, performing disconnection operation.
The detection of real-time isolation and recovery of the fault machine is achieved through the cooperative cooperation of the server and the client.
In an alternative embodiment, the embodiment of the present invention further supports dynamic extension of a message service cluster.
Specifically, the address of the existing service cluster may be statically configured in the "address" item of the message server, but it is not favorable for dynamic management of cluster scale, and when a machine is added or deleted, the configuration item is operated.
In the embodiment of the invention, zookeeper establishes a hierarchical node structure and supports temporary nodes. Establishing a configuration item directory node based on the service code and the message service end on the zookeeper, establishing a temporary node under an 'address' node of the message service end by the message service cluster when the application is started, and writing the address information of the message service cluster under the temporary node, thereby forming a dynamic registration mechanism. When a new machine is added into the cluster, only a new node is established under the address node, and similarly, when the machine leaves the cluster, the temporary node under the address node used by the machine pair is deleted to achieve the aim of canceling the machine.
By adopting the technical scheme, the dynamic expansion of the message service cluster is realized, and the flexibility of the message service is further improved.
In an optional embodiment, the embodiment of the present invention further supports: message service load balancing.
Specifically, for message transmission, a message service corresponds to a group of message servers, and message transmission needs to select one server for transmission, and for the case of transmitting a large number of messages, the capability of load balancing needs to be solved.
When a client calls a message platform, a service address list corresponding to a service code is obtained through the service code, then connection to the addresses is established, the connection is placed in a list, the list is randomly ordered, then a message is tried to be sent from the first connection in the list, if the message is sent successfully, the sending is completed, if the message is sent unsuccessfully, the next connection is taken down, the sending is tried unsuccessfully again, if one connection in the list is sent successfully, the sending is successful, and the sending is finished. If the last connection fails to send, the message sending fails, and a failure result is returned to the application. This strategy of random transmission ensures a balanced message transmission.
In an optional embodiment, the embodiment of the present invention further supports multi-room multi-active deployment.
For example, the message platform establishes three machine rooms of a foreign bridge, a south lake and a rice lake. Message services are deployed simultaneously in three rooms. For one message service cluster, peer message service terminals are deployed in three machine rooms simultaneously. When the message server dynamically registers the address, the message server registers the machine room deployment information of the message server to the zookeeper.
When the client sends the message and uses the service code to address, the client takes the own machine room deployment information as the addressing parameter and transmits the addressing parameter to the message platform, and the client preferentially selects the message service address of the corresponding machine room to the application according to the machine room information transmitted by the application. Therefore, the message sending end preferentially sends the message to the message server in the same computer room when sending the message. If there is no server of the corresponding room at the time of addressing, a previously configured addressing policy is used. The addressing strategy has both default polling and assigned priority. For the polling strategy, the sequential progression of (yangqiao, south lake, oryza) is specified, namely: if the address of the south lake should be found, if the address of the south lake cannot be found, the rice scented lake is found, and if the address of the rice scented lake cannot be found, the ocean bridge is addressed, and the process is carried out in a circulating mode. The priority-assigned strategy refers to addressing according to configured priorities under the condition that the corresponding service of the local machine room is not addressed, for example, the priority order of (ocean bridge, south lake and rice lake) is configured, if the application machine room is the south lake, if the address of the south lake cannot be found, the ocean bridge is preferentially addressed, and then the rice lake is addressed. The addressing policy is configured to the service code.
For such an addressing strategy, if the sender application is deployed by multiple machine rooms, interaction with the message service of the machine room is preferably selected, and if the message service of the machine room is unavailable, the message service of other machine rooms can be used. The message service capability of multiple computer rooms is provided. For an application receiving a message, a plurality of computer rooms are required to be connected simultaneously for message collection.
In an alternative embodiment, the embodiments of the present invention also support heterogeneous channel integration.
In particular, there are occasions when it is necessary to use different messaging platforms, subject to technical platform constraints. For example, in some banks, the mainframe system is not opened, and only WebphereMq can be used for message transmission on the mainframe system. Thus, the application component deployed on the large machine needs to use MQ when the component and the component on the open platform carry out message intercommunication. There are many optional platforms for message transmission between open systems, such as: qpid, kafka, rocktmq, etc. Thus, different message transmission channels are required to be used in different message scenarios. API encapsulation is carried out on qpid and WebphereMq, uniform message API supply application calling is provided, the difference of the two message middleware is shielded, and the application does not need to concern the realization of a bottom layer message transmission channel.
The API of the sending end comprises the following steps:
(1) logging in a message platform environment according to a service code to obtain a message service address;
(2) establishing connection according to the acquired message service address;
(3) sending a message using the connection;
(4) closing the connection;
the receiving end API comprises the following steps:
(1) logging in a message platform environment according to a service code to obtain a message service address;
(2) establishing connection according to the acquired message service address;
(3) receiving a message using the connection;
(4) sending a message using the connection;
the client API acquires the service address configuration corresponding to the service code from zk according to the service code, acquires the protocol type according to the front bits in the configuration url and acquires the protocol type according to different protocol types, thereby determining the type of the message channel and calling different message channels to establish corresponding connection objects. Different message channels correspond to different connection object types. Therefore, the message sending and receiving can be operated on different connection objects, and the purpose of heterogeneous channel integration is achieved.
In summary, according to the message service access method based on the zookeeper provided by the embodiment of the present invention, information is dynamically written to the zookeeper, and is updated to the client in time after being changed, and the client does not need to restart application for updating configuration. When the number of messages is increased and the server needs to expand capacity, the client can acquire a new service address in time, and when the server is abnormal, the client can be isolated and recovered in time, so that the complexity of accessing the message service by application is reduced, the internal complex mechanism of a message platform is shielded, the management efficiency of a large-scale message cluster is improved, and the load balancing capability and the capability of deploying a plurality of message service rooms are provided.

step S1000: sending a message service code to the zookeeper to acquire corresponding configuration information;
specifically, a client accesses a zookeeper through a message service code and zookeeper information which are sent to the client in advance by a server, and sends the message service code to the zookeeper so as to acquire configuration information which is fed back by the zookeeper and corresponds to the message service code; and then performs a message service according to the configuration information.
Step S2000: comparing the configuration information with local configuration information stored in a message cache region;
it should be noted that there is a possibility that the configuration information may change during the message service, and the zookeeper sends the configuration information change message to the message buffer of the client by using the watchdog mechanism of the zookeeper when the configuration information is changed.
Step S3000: judging whether the connection with the server needs to be reestablished or not according to the comparison result;
the client can obtain the address of the server through a cache mechanism, and meanwhile, the client can judge whether the address is changed or not, so that whether the message access environments such as connection and the like need to be reestablished or not is judged. The connection establishment is time consuming, so when the message address changes, it should be compared which addresses are unchanged, which addresses are newly added, and which addresses are deleted, and different change strategies are adopted for the new addition, the unchanged addition and the deletion. For addresses that do not change, the connection does not need to be updated. And for the newly added address, establishing a new connection, updating the new connection into the available connection list, and for the deleted address, performing disconnection operation.
By adopting the scheme, the watchdog monitoring mechanism of the zookeeper can be effectively utilized, after the configuration information is updated, the updated configuration information is timely sent to the parameter cache region of the client registered to the watchdog monitoring, when the client sends the message, whether the configuration information is changed compared with the configuration information of the parameter cache region is judged, and the subsequent operation is carried out according to the judgment result, so that the service abnormity caused by the fact that the configuration information is not timely updated to the client in the change of the configuration information can be prevented.
Based on the same inventive concept, the embodiments of the present application further provide a client device, which can be used to implement the methods described in the foregoing embodiments, as described in the following embodiments.
