In intranet and extranet communication, the key point is strong isolation, and the key point of strong isolation is the use of a database. Therefore, the intranet and extranet communication message queue is a self-developed message queue middleware realized based on the existing technical means of strong isolation devices, databases and message queues, and has the basic functions of the message queue. It is a product under the environment of specific network requirements, and is only suitable for data transmission between internal and external networks. The implementation of the indbmq enables the message queue technology commonly used by the internet to be widely applied, and some common queue use scenes can also be applied. The system can process the communication of the internal and external networks with high efficiency, low delay, high concurrency and high stability, thereby providing technical support for the communication of the internal and external networks.
According to the requirements of internal and external network communication, a strong isolation device and a relational database must be used. Therefore, the intranet and extranet communication message queue system (hereinafter referred to as indbmq) adopts the design concept that an intranet and an extranet are respectively provided with one set of system, and the two sets of systems serve as data interaction centers through the mysql database. And deploying an indbmq system in the intranet environment, wherein the system is directly connected with an intranet mysql database. And (3) deploying an indbmq system in the external network environment, and connecting the system to the mysql database address exposed to the external network through a strong isolation device. Therefore, the requirement for internal and external network communication is met, and the function of internet message queue is realized.
The function of the indbmq system is as follows:
(1) the method realizes the basic message queue function, supports the dynamic creation of the theme, supports the basic receiving and sending of the message, supports the push-pull mode and ensures the accurate consumption of the message.
(2) The performance is fast and the original efficiency is high, and the performance is improved by times independently from the original performance. The stability aspect is also superior to the original implementation mode alone.
(3) The method is developed quickly and provides simple SDK packaging implementation. Developers are only concerned with the message queue middleware itself. There is no need to pay attention to the internal and external network problems.
(4) Distributed is supported, as are other distributed message queues supporting distributed cluster deployment. Through the distributed mode, alleviate single-point pressure, solve the performance bottleneck problem. For late stage development and high concurrency of indbmq. The system is designed in a multi-subsystem architecture. I.e. indbmq consists of two parts: namesrv and brooker. The design has the advantage that if the access pressure of the indbmq is continuously increased, a multi-browser node deployment mode can be adopted, and a plurality of browser nodes are in long connection with the namesrv through the listening ports, so that the access pressure can be dispersed to each browser node, and the access pressure of a single browser is relieved. When the system calling pressure is increased, the namesrv can be clustered and deployed, and the calling pressure is reduced. Aiming at the later development of the indbmq, other subsystems can be additionally arranged for cooperative operation.
(5) When a timing task is set in the system, the consumed message data can be backed up to a corresponding history table after one hour. The backup and traceability of the message data are realized. A timed task mechanism is added to the indbmq, and at intervals, the indbmq will migrate consumed messages elsewhere. Therefore, the pressure of the database is relieved, and the consumed messages can be subjected to tracing query. This is very important in some application scenarios.
(6) The product supports asynchronous transmission of pictures between an internal network and an external network. The traditional MQ product can only produce and consume character data. And the design of the indbmq is not only the same, but also the system can support the asynchronous transmission of pictures and can meet more application scenes. And asynchronous transmission of pictures between the internal network and the external network is supported. The transmission type of the message is enriched. And the Indbmq stores the picture information sent by the producer into the mysql database according to the storage characteristics of the mysql database, and acquires the picture from the database when the consumer consumes the message.
Further, when using indbmq, a message queue may be used like rocktmq. Therefore, the learning cost can be saved, and the operation is faster.
Further, the conventional MQ products store message data in files, and only store the message data in a database according to the requirements of the network. Thus, file storage needs to be converted into database storage. Then follows the problem of database typing, and the mainstream database in the market at present has two types of oracle and mysql. Because the use environment of the system is complex, multi-scenario deployment and absolute separation of data are possible, a light weight of data is needed. The advantages of mysql are now more apparent. Mysql is therefore selected as a storage carrier for the message data.
Based on the foregoing communication system, an embodiment of the present invention provides a communication method, where in a process of writing data in a first terminal and reading data from a second terminal in the communication system, an execution flow of the communication method is shown in fig. 2, and the method includes:
s101, the first terminal writes first data into a database through a first message queue;
in the embodiment of the present invention, when the first message queue receives a write request sent by the first terminal, first data included in the write request is acquired, and the first data is written into the database.
S102, the second message queue accesses the database through a strong isolation device, obtains the first data, and sends the first data to the second terminal through the strong isolation device.
In the embodiment of the present invention, the second message queue continuously accesses the database through the strong isolation device in a polling manner, and when it is detected that the first data is stored in the database, the detection manner may be continuously searching at a specified position of the database or receiving a preset instruction or other detection manners.
Based on the communication system, an embodiment of the present invention provides a communication method, which is applied to a process of a first terminal reading data and a second terminal writing data in the communication system, and an execution flow of the communication method is shown in fig. 3, where the method includes:
s201, the second terminal writes second data into a database through a second message queue and a strong isolation device;
in the embodiment of the present invention, when the second message queue receives a write request sent by the second terminal, second data included in the write request is acquired, and the second data is written into the database.
S202, the first message queue accesses the database, the second data are obtained, and the second data are sent to the first terminal.
In the embodiment of the present invention, the first message queue continuously accesses the database through the strong isolation device in a polling manner, and when it is detected that the second data is stored in the database, the detection manner may be continuously searching at a designated position of the database or receiving a preset instruction or other detection manners.
In the embodiment of the invention, the communication method is described by taking the use process of an intranet and extranet communication message queue as an example, an indbmq system is respectively deployed in an intranet server and an extranet server, the indbmq of the intranet is directly connected with a database, and the extranet indbmq is directly connected with a strong isolation access database. Because indbmq has the function of both inserting data into and retrieving data from the database. So that the bidirectional communication of the internal network and the external network is realized. When the internal network generates messages and the external network consumes: the intranet indbmq stores the messages produced by the producer in a database, and the extranet indbmq takes out the message data from the database through strong isolation and sends the message data to the consumer for consumption. When the outer net produces messages and the inner net consumes: the extranet indbmq stores the message produced by the producer into the database through strong isolation, and the intranet indbmq takes out the message information from the database and sends the message information to the consumer for consumption. The implementation process of the spring boot application integration indbmq mode is as follows:
(1) message producer integration approach
Adding relevant dependencies in a pom file
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>spring-boot-starter-rocketmq</artifactId>
<version>1.0.1</version>
</dependency>
Adding corresponding configuration information in the configuration file:
pring:
rocketmq:
nameServer: 127.0.0.1:8764;127.0.0.1:8765
producer:
group: producer-group
the RockMQTemplate object may then be used to send a message to indbmq
@Resource
private RocketMQTemplate rocketMQTemplate;
public void send(String msg) {
this.rocketMQTemplate.convertAndSend(topic,"Hello, World!" + msg);
}
(2) Message consumer integration approach
Adding relevant dependencies in a pom file
<dependency>
<groupId>org.apache.rocketmq</groupId>
<artifactId>spring-boot-starter-rocketmq</artifactId>
<version>1.0.1</version>
</dependency>
Adding corresponding configuration information in configuration file
spring:
rocketmq:
nameServer: 127.0.0.1:8764;127.0.0.1:8765
producer:
group: producer-group
The RockMQListener listening can then be used to retrieve the messages within indbmq
@Service
@RocketMQMessageListener(topic = "tooapi-test", consumerGroup = "topic-consumer-group")
public class ConsumerRocketMQListener implements RocketMQListener<String>{
public void onMessage(String message) {
System.out.println("veceived message: " + message);
}
}
Further, aiming at the implementation process, the two sets of indbmq use the same message storage pool, so that the message sharing problem is realized. Indbmq adopts the design of double addresses of the same database. That is, the intranet indbmq is directly connected with the intranet database, and the intranet database exposes another connection address through the strong isolation device for connection of the extranet indbmq. The two databases are actually operated by the same database. Therefore, two sets of indbmq are connected with the same database, and data sharing is guaranteed.
When the mysql database is used for storing the messages, the problems of repeated consumption prevention of the messages and retrieval pressure of the database are also considered. Therefore, the indbmq makes full use of the transaction characteristics of the database, and ensures the unique consumption of the message at the transaction level of the database. When indbmq is run for a period of time, it is followed by database retrieval pressure issues. Since the amount of data in the data pool gradually increases with time, the database search pressure also gradually increases. So indbmq employs a timed migration mechanism. I.e., migrating consumed message data out of the message pool at intervals. This greatly eases the pressure on database retrieval.
In certain scenarios, a message traceable mechanism is also necessary. For example, when the payment system sends a payment message, the message is consumed normally. After several months the service personnel find this payment message problematic and need a full link lookup for traceability. In this case, the message traceability mechanism is important. Indbmq can quickly find the consumed message in the consumed message pool, so that the safety of the service is ensured.
The indbmq may be used only in an extranet environment or an intranet environment. Indbmq not only realizes the two-way communication between the internal network and the external network, but also supports the communication between the internal network and between the external network and the external network. Thus, the application scenes of the indbmq are wider. The indbmq can be used in any scenario where the database is used as a message carrier.
