Description
Technical Field
The present invention relates to the field of message processing technologies, and in particular, to a message processing method, a message processing apparatus, and a storage medium.
Background
Currently, message middleware systems mainly employ centralized deployment structures, such as Kafka, RabbitMQ, etc., as shown in fig. 1. The network nodes in the system are divided into user nodes (running processes for receiving and sending messages by using message middleware, called user processes) and message service nodes (nodes for providing message transit service, running message service programs). By network node is meant a networked device, such as a computer, embedded device, etc., running these programs. All user processes of the user nodes are connected to the message service node, and mutual connection does not exist between all user nodes and processes. The user process sends the message to the message service node, and the message service node forwards the message to the user process needing the message.
The above message transmission structure belongs to a centralized structure, which relies heavily on message service nodes, which are likely to become performance bottlenecks and reliability risk points of the whole system. If the message service node fails, the entire system will be disabled.
In addition, the centralized structure needs to be transferred through the message service node, so that the network flow is enlarged, and the message delay is increased. For example, the user node 1 sends the message to the user node 2, and needs to send the message to the message service node first, and then the message service node forwards the message, and this forwarding process greatly accumulates network traffic at the message service node. Therefore, the existing message processing method is based on the technical problem of low reliability caused by overlarge network traffic.
Therefore, the prior art is to be improved.
Disclosure of Invention

the user process module acquires a message to be sent and sends the message to be sent to a message bus process module of the network node; the message to be sent carries relevant information of a target network node and a target user process;
when receiving the message to be sent from the network node, the message bus process module judges whether the related information of the target network node belongs to the message to be received of the network node; if so, the message bus process module sends the message to be sent to a user process module corresponding to the relevant information of the target user process in the network node; if not, sending the message to be sent to the message bus process module of the corresponding network node;
and the message bus process module also forwards the message to be sent to a user process module corresponding to the relevant information of the target user process in the network node where the message to be sent is located when receiving the message to be sent from other network nodes.

The invention provides a message processing method, a device and a storage medium based on a message middleware, wherein the message middleware comprises a plurality of network nodes, each network node comprises a message bus process module and a plurality of user process modules which are connected to the message bus process module, and the message bus process modules of the network nodes are connected with each other, so that the message middleware of a decentralized deployment structure is formed. The identities of all network nodes in the system are equal, network connection is established mutually, and no central node exists. Therefore, the invention judges which network node in the message middleware is the target network node according to the target network node carried by the message to be sent and the related information of the target user process during the message processing process, and the transmission is carried out only through the message bus process module and the user process modules in the whole message sending and receiving process without passing through the message service node, thereby overcoming the problems of a centralized structure, having the advantages of high performance, high reliability, low network flow and low delay, and being suitable for being applied to an industrial field monitoring system.

The message processing method based on the message middleware provided by the invention is suitable for the message middleware shown in figure 2, and the message middleware is provided with a plurality of network nodes with consistent structures. Each network node comprises a message bus process module and a plurality of user process modules which are connected to the message bus process module, and the message bus process modules of the network nodes are connected with each other, so that a message middleware of a decentralized deployment structure is formed. According to the system structure of the message middleware, the message bus process module and the user process module are arranged in two structures, a traditional message service node is not provided, the problems of a centralized structure are solved, and the message middleware has the advantages of high performance, high reliability, low network flow and low delay, and is suitable for being applied to an industrial field monitoring system.
Fig. 3 is a flowchart illustrating a message processing method based on message middleware according to a first embodiment of the present invention, where the method includes:
step S301, a user process module acquires a message to be sent and sends the message to be sent to a message bus process module of the network node; the message to be sent carries relevant information of a target network node and a target user process;
in this embodiment, the target network node represents a network node corresponding to a message to be sent, that is, the target network node is a network node that needs to process information to be sent, and the related information of the target network node may be a name, a number, and the like of the target network node, and the related information of the target user process may be a name, a number, and the like of a target user process module, where the related information is not specifically limited.
Step S302, when the message bus process module receives the message to be sent from the network node, whether the relevant information of the target network node belongs to the message to be received of the network node is judged; when the judgment result is yes, the message bus process module sends the message to be sent to a user process module corresponding to the relevant information of the target user process in the network node; if not, sending the message to be sent to a message bus process module of the corresponding network node;
step S303, when receiving the message to be sent from other network nodes, the message bus process module forwards the message to be sent to the user process module corresponding to the information related to the target user process in the network node where the message to be sent is located.
In this embodiment, each network node is in the same message domain, where the message domain is a set of predefined (configured) network nodes, and the configuration of one message domain includes a unique name (e.g., a host name) of each network node and an IP address of each network node. That is, each network node in the message domain realizes data transmission based on each IP address without relying on a conventional message service node for forwarding.
Therefore, when each network node carries out a message processing process, the judgment is carried out through the relevant information of the target network node and the target user process carried by the message to be sent, and when the message to be sent is determined not to belong to the message to be received in the network node (namely, the message to be received is indicated to be the target network node by the rest network nodes in the message domain), the message bus process module of the network node sends the message to be sent to the message bus process module of the corresponding network node. That is, if the sender and the receiver of the message are both in the same node, the message is forwarded by the message bus service process in the node of the network, i.e. the local interaction, without passing through the network. In the traditional centralized structure, the message needs to be forwarded through the message service node and needs to pass through the network. Therefore, the message middleware reduces network flow and communication delay. The method has the advantages of high performance, high reliability, low network flow and low delay, and is suitable for being applied to an industrial field monitoring system.
Fig. 4 is a flowchart illustrating a message processing method based on message middleware according to a second embodiment of the present invention, where the second embodiment defines a message to be sent and related information of a target network node in the first embodiment, where the message to be sent includes a peer-to-peer message, and the related information of the target network node includes a target node name; the second embodiment also defines the step of determining whether the related information of the target network node belongs to the message to be received of the network node, and includes:
step S401, the message bus process module identifies the name of the target node from the related information of the target network node;
step S402, the message bus process module matches the name of the target node with the name of the network node to obtain a matching result;
step S403, the message bus process module determines whether the peer-to-peer message belongs to a message to be received of the local network node according to the matching result.
Specifically, when the message to be sent includes a point-to-point message, the local process processing module in the network node identifies the name of the target node from the related information of the target network node, and then the local process processing module in the network node matches the name of the target node with the name of the network node to obtain a matching result. The obtained matching result can be a matching result that the name of the target node is equal to the name of the network node, or the name of the target node is not equal to the name of the network node, so that the local process processing module in the network node detects whether the peer-to-peer message belongs to the message to be received in the network node according to the matching result. In the transmission process of the point-to-point message, the attribution judgment of the point-to-point message is completed accurately and quickly through the name of the target node.
In this embodiment, the step of sending the message to be sent to the user process module corresponding to the relevant information of the target user process in the network node by the message bus process module includes:
step S404, the message bus process module identifies the name of the target user process according to the relevant information of the target user process;
step S405, the message bus process module sends the message to be sent to the user process module corresponding to the target user process name in the network node.
Specifically, in the transmission process of the peer-to-peer message, the related information in the peer-to-peer message may also have a target user process name, and based on that each network node has a unique node name in the message field, each user process has a unique process name in the node, so that a unique receiving address may be determined. That is, the target network node is determined by the target user process name, so that the message bus process module of the network node accurately sends the message to be sent to the user process module corresponding to the target user process name in the network node.
In this embodiment, before the step of sending the message to be sent to the message bus process module of the corresponding network node, the method further includes:
step S406, the message bus process module in the network node acquires the communication connection state of the message bus process module of the corresponding network node;
step S407, when the communication connection state is in the unconnected state, the message bus process module in the network node deletes the point-to-point message;
step S408, when the communication connection state is in the connected state, the message bus process module in the network node sends the point-to-point message to the message bus process module of the network node corresponding to the target node name.
Specifically, after the message bus process module of the network node obtains the point-to-point message, the message bus process module of the network node needs to obtain a communication connection state of the message bus process module of the corresponding network node, where the communication connection state indicates whether the message bus process module of the corresponding network node is in an online state. Obviously, when the communication connection state is the disconnection state, it indicates that the message bus process module of the corresponding network node is in the disconnection state. And when the communication connection state is the connected state, the message bus process module corresponding to the network node is indicated to be in the online state. Therefore, before the message bus process module of the network node transmits the point-to-point message to the message bus process module of the corresponding network node, whether the point-to-point message needs to be sent is determined based on the communication connection state, and transmission power consumption is reduced to a certain extent.
As shown in fig. 5, the message bus process module has a remote process module and a local process module, and the user process module has an in-process agent module and a communicator. The local process processing module identifies a target node name from the related information of the target network node, matches the target node name with the local network node name to obtain a matching result, and judges whether the point-to-point message belongs to a message to be received of the local network node according to the matching result. And the local process processing module identifies the name of the target user process according to the related information of the target user process, and sends the message to be sent to a user process module corresponding to the name of the target user process in the network node. And the in-process agent module acquires the communication connection state of the message bus process module corresponding to the network node, deletes the point-to-point message when the communication connection state is in an unconnected state, and sends the point-to-point message to the message bus process module of the network node corresponding to the name of the target node when the communication connection state is in a connected state.
The method comprises the following steps that a plurality of user process modules in each network node are provided with communicators, a message to be sent also carries a target communicator name, and the message to be sent is forwarded to a user process module corresponding to related information of a target user process in the network node where the message to be sent is located, and the method comprises the following steps: and the message bus process module identifies the name of the target communicator according to the message to be sent, and forwards the message to be sent to the communicator which is positioned in the network node and corresponds to the name of the target communicator. Specifically, when the network node receives the message to be sent, the message bus process module gives the name of the target communicator and forwards the message to be sent to the communicator corresponding to the name of the target communicator in the network node where the network node is located, so that the transmission of the message to be sent in the network node is realized without passing through a message service node. The communicator module is used as a terminal unit of the message bus and can also be used for receiving and transmitting messages of user codes, increasing, deleting, modifying, checking and the like of subscriptions.
Fig. 6 is a flow diagram illustrating a message processing method based on message middleware according to a third embodiment of the present invention, in which the message bus process module further has a local process subscription management module, and the message to be sent further includes a subscription message with a topic; i.e. each network node is also adapted to a publish-subscribe mode. The step of judging whether the related information of the target network node belongs to the message to be received of the network node comprises the following steps:
step S601, the message bus process module sends the subscription message to the local process subscription management module;
step S602, the local process subscription management module identifies a topic from the subscription message;
and the local process subscription management module judges whether the message to be sent belongs to the message to be received of the network node according to the theme.
Wherein the theme may be a theme name, such as a power monitoring subsystem or a fire protection subsystem; the topic is used as the attribute of the subscription message and is set by the user code when sending the message according to the actual meaning of the service. The user code may set any number of topics of interest to the communicator according to its business requirements, called subscriptions, which the communicator may subsequently receive messages matching its subscriptions. In short, it can be quickly and simply determined whether the information to be transmitted is the information to be received of the first network node by the theme.
In this embodiment, the topic may further include a subsystem name and a channel segment name, and specifically, the topic may be a multi-segment line, such as "xxx. Currently, a two-terminal theme is adopted, namely 'subsystem and channel'. Firstly, each segment is matched independently, if equal, the segment is matched, and if not equal, the segment is not matched; and then, solving the logical AND of the matching results of the segments, namely that all the segments are matched and are matched integrally. When subscribing, any segment can be set to 'all', and then the segment matches any value. Assuming that the topic of a message is "power monitoring subsystem measures point data change channel", the matching result of the subscription is shown in the following table 1:
TABLE 1
The communicator may subscribe to any number of topics, wherein the communicator receives a message as long as one subscription matches the topic of the message. Assuming that the topic of a message is "video subsystem, alert channel", the added subscription of the communicator is as follows, and whether the communicator will receive the message is as follows in table 2:
TABLE 2
The step of judging, by the local process subscription management module, whether the message to be sent belongs to a message to be received of the network node according to the topic includes:
step S603, the local process subscription management module determines the subscription integral matching degree of the topic according to the subsystem name and the channel segment name;
step S604, the local process subscription management module determines whether the message to be sent belongs to the message to be received of the network node according to the subscription overall matching degree.
Specifically, a local process subscription management module in the network node extracts a first subscription message and a second subscription message (the first subscription message and the second subscription message are information pre-stored in the local process subscription management module and can feed back the subscribed subscription message in the network node), matches the first subscription message with the subsystem name, and matches the second subscription message with the subsystem name; as can be seen from table 2 above, when the subsystem names match correctly and the channel segment names match correctly, the subscription global matching degree is correct. And when the name of the subsystem is matched and at least one of the channel segment names has a matching error, the matching degree of the whole subscription is the matching error.
In this embodiment, the message bus process module further has a remote node subscription management module;
the step of sending the message to be sent to the message bus process module of the corresponding network node includes:
step S605, the message bus process module sends the subscription message to the remote node processing module of the local network node;
step S606, the remote node processing module of the network node detects whether the target network node subscribes to the subscription message;
step S607, when the target network node subscribes to the subscription message, the remote node processing module of the network node sends the subscription message to the target network node.
In this embodiment, when the local process subscription management module in the local network node detects that the subscription message does not belong to the message to be received of the local network node (indicating that the subscription message should be the message to be received of the other network nodes) according to the subscription overall matching degree, the local process processing module in the local network node sends the subscription message to the remote node processing module in the local network node, the local process processing module in the local network node sends the subscription message to the remote node subscription management module in the local network node, the remote node subscription management module in the local network node detects whether the other network nodes subscribe to the subscription message (it should be noted that when the other network nodes subscribe to the subscription message, it indicates that communicators in the other network nodes have subscribed topics), if the other network nodes subscribe to the subscription message, the remote node subscription management module in the network node sends the subscription message to the target network node. Thereby, a fast transmission of subscription messages between different network nodes is accomplished.
In this embodiment, a communicator management subscription module is disposed in the user process module, and when the target network node does not subscribe to the subscription message, the following steps are performed:
step S608, the remote node processing module of the network node sends the subscription message to the in-process agent module of the network node;
step S609, the in-process agent module of the network node acquires the communicator which subscribes the subscription message through the communicator management subscription module;
step S610, the in-process agent module of the network node sends the subscription information to the communicator which subscribes the subscription information.
Therefore, when the target network node does not subscribe the subscription message (indicating that the subscription message is the information to be received by the network node), the information transmission in one network node is realized based on the remote node processing module, the communicator management subscription module and the communicator in the network node, and the subscription message does not need to pass through the message service node, so that the low network flow is effectively reduced.
It can be seen that, in both the point-to-point mode and the subscription and publication mode, if the sender and the receiver of the message are in the same node, the message is forwarded by the message bus service process (native process processing module) in the node, i.e. the native interaction, without passing through the network. In the centralized structure, the message needs to be forwarded through the message service node and needs to pass through the network. Therefore, the message middleware reduces network flow and communication delay.
In addition, for the subscription and publication mode, in cross-node communication, a message is subscribed by any number of processes or communicators in a node, only one message is transmitted to the node through a network, and then the message is distributed to each target user process by a message bus service process in the node and then distributed to each communicator by an agent module in the process. Therefore, the message middleware reduces the network flow and avoids network congestion.
In this embodiment, when each network node is in the subscription and publication mode (during the transmission process of the subscription information), the method further includes the following steps: the communicator receives a subscription adjustment instruction of a user, the communicator sends the subscription adjustment instruction to an in-process proxy module, the in-process proxy module controls a communicator subscription management module to modify subscription information of the communicator and obtains a first feedback result, the in-process proxy module judges whether the modification causes the overall subscription condition of the in-process according to the feedback result, if yes, the in-process proxy module sends the overall subscription change information of the in-process to a message bus process module of the network node, a local process processing module controls the local process subscription management module to modify the subscription information and obtains a second feedback result, the local process processing module judges whether the modification causes the overall subscription condition of the network node according to the second feedback result, if yes, the subscription change information is sent to a remote node processing module, and the remote node processing module sends the subscription change information to remote nodes of other network nodes And the remote node processing modules of the other network nodes operate the remote node subscription management module to modify the subscription information.
The "overall subscription condition of the process" refers to a deduplication (deduplication removing) set of subscriptions of all communicators in the process. Such as table 3 below:
TABLE 3
| Communicator 1 subscription | “aaa.111”、“bbb.333” |
| Communicator 2 subscription | “aaa.111”、“ddd.222” |
| Overall subscription | “aaa.111”、“bbb.333”、“ddd.222” |
And the analogy is the same as that of the 'overall subscription condition of the node'. In addition, subscription change version numbers of a sender are carried in subscription change messages and heartbeat messages between a user process and a message service process of the node, as well as between the nodes, and the version numbers are continuously increased by 1 every time the subscription change messages and the heartbeat messages are changed. When the receiver finds that the version number is discontinuous, which indicates that an exception occurs, the receiver requests all the subscription information of the receiver from the sender.
In this embodiment, the method further includes: after a message bus service process module of the network node is started, names and IP addresses of other network nodes in the message domain are obtained from message domain configuration, a TCP client in a remote node processing module of the network node initiates TCP connection to the corresponding network node, whether the connection is successful or not is judged, if the connection is successful, the remote node processing module sends heartbeat messages (the heartbeat messages comprise the local name and the subscription change version number), after the other network nodes receive the heartbeat messages, the remote node management module of the other network nodes records that the subscription change version number of the network node is invalid or is not equal to the heartbeat messages, the messages requesting all subscription information are described and enter a sending queue of the network node, if the TCP client of the other network nodes corresponding to the network node is not connected, the connection to the local network node is initiated, if the network nodes are connected, sending messages requesting all subscription information, receiving all the subscription information recovery of the network nodes by the rest network nodes, setting the connection state of the network nodes in the management information as connected, operating the remote node subscription management unit, recording the subscription information and the subscription change version number of the network nodes, and setting the version number as valid. The steps are the online processes of all network nodes.
In this embodiment, the method further includes: when the message bus service process module of the network node is actively withdrawn, the remote node processing module sends the withdrawal message of the network node to other connected network nodes, when the other network nodes receive the withdrawal message of the network node or do not receive the heartbeat message after overtime, the other network nodes set the connection state of the network node in the management information as the unconnected state, and the remote node subscription management module is operated to delete all subscription messages of the network node and set the subscription version number of the subscription message as invalid. And disconnecting the TCP server and the TCP client from the connection established with the network node, and connecting the other network nodes with the TCP client of the network node at intervals of a preset time period. The steps are the off-line process of each network node.
