It is the container of the message and also the end of the message. A message may be placed into one or more queues. Messages remain in the queue waiting for the consumer to connect to the queue to take them away.
The transmitting end uses the agreed communication connection to configure a read-write engine of the transmitting end, and the read-write engine comprises a read interface, a write interface, a route manager and a queue manager. The queue manager of the read-write engine creates 2 Rabbit MQ message queues to serve as a channel of bidirectional traffic according to the communication connection configuration, so that a sending end and a receiving end can use the corresponding left-direction queues or right-direction queues to monitor messages sent by the other side.
In step S102, the transmitting end binds the rabit MQ switch with the left queue according to the left routing rule, and binds the rabit MQ switch with the right queue according to the right routing rule.
The read-write engine of the transmitting end actively connects with the Rabbit MQ according to the configuration information, configures the corresponding message queue name, the router and binds the corresponding queue according to the routing rule.
Specifically, the read-write engine generates a routing rule key according to the communication connection configuration: connection. Duplex. Right and key: connection.

It is the container of the message and also the end of the message. A message may be placed into one or more queues. Messages remain in the queue waiting for the consumer to connect to the queue to take them away.
The transmitting end and the receiving end use the agreed communication connection configuration to set the read-write engine of the transmitting end and the receiving end, and the read-write engine comprises a read interface, a write interface, a route manager and a queue manager. The queue manager of the read-write engine creates 2 Rabbit MQ message queues to serve as a channel of bidirectional traffic according to the communication connection configuration, so that a sending end and a receiving end can use the corresponding left-direction queues or right-direction queues to monitor messages sent by the other side.
In step S202, the receiving end binds the rabit MQ switch with the left queue according to the left routing rule, and binds the rabit MQ switch with the right queue according to the right routing rule.

The read-write engine generates a routing rule key according to the communication connection configuration: connection.duplex.right.1, key: connection.duplex.right.2 and key: connection. After the queue manager of the read-write engine successfully creates a left-direction queue and a right-direction queue, according to the routing rule key: connection.duplex.right.1 binds the first right-hand queue according to the routing rule key: connection.duplex.right.2 binds the second right-hand queue, key: connection.
In step S203, the receiving end actively sends a handshake message according to the routing rule.

Duplex. Left actively sends a handshake message, and communication is started after a sending end receives the handshake message sent by a first receiving end or a second receiving end.
The sending end receives the message by using the left queue and passes the key: connection.duplex.right.1, key: connection. Duplex. Right.2 sends a message to the switch. The first receiving end and the second receiving end respectively use the first right-direction queue and the second right-direction queue to receive the message and pass through the key: connection.
When the queue manager of the transmitting end monitors that the left queue has information, the information is written into the reading interface of the transmitting end. When the queue manager of the transmitting end monitors that the writing interface has information writing, the queue manager monitors that the writing interface has information writing according to the corresponding routing rule key: connection.duplex.right.1 or key: connection.duplex.right.2 sends the information to the switches of the rabitmq.
In step S204, the receiving end listens to whether the switch of the rabitmq is on line.
The communication connection configuration to be used is agreed by the sending end and the receiving end, and the communication connection configuration comprises the following steps: the device comprises a Rabbit MQ address, a user name, a password, a secret key, a switch to be used in communication, a left queue and a right queue. The switch is used to receive messages sent by message publishers and route those messages to queues in the server. The left and right queues are used to hold messages until sent to the consumer. It is the container of the message and also the end of the message. A message may be placed into one or more queues. Messages remain in the queue waiting for the consumer to connect to the queue to take them away.
The receiving end uses the agreed communication connection configuration to set the read-write engine of the receiving end, the read-write engine of the receiving end is actively connected with the RabbitMQ according to the configuration information, and whether the switch of the RabbitMQ is on line is monitored. If the route to the exchanger of the Rabbit MQ is monitored, information is written into a writing interface representing a sending end, and the information is written into the writing interface through a corresponding routing rule key: connection.
In step S205, when the queue manager at the receiving end monitors that the right queue has information arrived, the information is written into the read interface at the receiving end.
The first receiving end and the second receiving end respectively use the first right-hand queue and the second right-hand queue to receive the information of the sending end and pass through the key: connection. Duplex. Left sends messages to the switches of the Rabbit MQ, respectively.
When information is written in a writing interface of a sending end, the information is written in through a corresponding routing rule key: connection.duplex.right.1 or key: the connection, duplex, right.2 sends the information to the switch of the Rabbit MQ, the switch sends the information to the first right-hand queue and the second right-hand queue respectively, at this time, the queue managers of the first receiving end and the second receiving end can monitor that the corresponding right-hand queues have information to arrive, and the queue managers of the first receiving end and the second receiving end write the information into the corresponding reading interfaces.
