Example 1
Referring to fig. 1 to 5, a method for rabbitit MQ duplex communication according to an embodiment of the present invention is described, which includes the following steps.
In step S101, the transmitting end creates a left-directional queue and a right-directional queue, respectively.
The working principle of the RabbitMQ is that a message publisher sends a message to a RabbitMQ proxy server, a switch in the proxy server receives the message, the message is transmitted to a message queue bound with the switch and stored, and a consumer establishes connection with the message proxy server and then takes out the message from the corresponding message queue for processing.
The communication connection configuration which is appointed to be used by a sending end and a receiving end comprises the following steps: the system comprises a Rabbit MQ address, a user name, a password, a key, a switch to be used during communication, a left queue and a right queue. The switch is used to receive messages sent by message publishers and route the 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 point of the message. A message may be dropped into one or more queues. The message is always in the queue waiting for the consumer to connect to this queue and take it away.
The sending terminal configures a read-write engine of the sending terminal by using a conventional communication connection, wherein the read-write engine comprises a read interface, a write interface, a routing manager and a queue manager. The queue manager of the read-write engine establishes 2 Rabbit MQ message queues serving as channels of bidirectional flow according to communication connection configuration, so that a sending end and a receiving end can use respective corresponding left-direction queues or right-direction queues to monitor messages sent by an opposite side.
In step S102, the sending end binds the rabbitmq switch with the left queue according to the left routing rule and binds the rabbitmq switch with the right queue according to the right routing rule.
And the read-write engine of the sending end is actively connected with the Rabbit MQ according to the configuration information, configures the corresponding message queue name and the router and binds the corresponding queue according to the routing rule.
Specifically, the read-write engine generates a routing rule key according to communication connection configuration: connection.duplex.right and key: complete. left, and create a dedicated communication route. After the queue manager of the read-write engine successfully creates the left queue and the right queue, according to a routing rule key: connection.duplex.right binding right queue, key: connection.duplex.left binds the left queue and informs the queue manager of the ready initialization, thereby realizing duplex communication.
In step S103, the transmitting end communicates with the receiving end after monitoring the handshake message of the receiving end in the left queue.
After receiving a ready signal sent by a routing manager, a queue manager at a sending end starts to monitor messages in a left queue, and a receiving end uses a key: connection.duplex.left actively sends a handshake message, and starts communication after a sending end receives the handshake message sent by a receiving end.
The sending end receives the message by using the left queue and by key: connection.duplex.right sends a message to the switch. The receiving end receives the message by using the right-direction queue and by key: connection.duplicate.left sends a message to the switch.
And when the queue manager at the sending end monitors that the left queue has information, writing the information into a reading interface of the sending end. When the queue manager at the sending end monitors that the writing interface has information to write, according to the corresponding routing rule key: connection.duplex.right sends the information to the exchange of the rabbitmq.
When the sending end or the receiving end needs to be disconnected, an ending message needs to be sent, and after the opposite end receives the disconnection of the ending message, the sending end actively clears the switch, the left queue and the right queue of the RabbitMQ.
Example 2
Referring to fig. 6 to 8, a method for rabbitit MQ duplex communication according to an embodiment of the present invention is described, which includes the following steps.

In this embodiment, one transmitting end corresponds to multiple receiving ends.
The working principle of the RabbitMQ is that a message publisher sends a message to a RabbitMQ proxy server, an exchanger in the proxy server receives the message, transmits the message to a message queue bound with the exchanger and stores the message, and a consumer establishes connection with the message proxy server and then takes the message out of the corresponding message queue for processing.
The communication connection configuration which is appointed to be used by a sending end and a receiving end comprises the following steps: the system comprises a Rabbit MQ address, a user name, a password, a key, a switch to be used during communication, a left queue and a right queue. The switch is used to receive messages sent by message publishers and route the 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 point of the message. A message may be dropped into one or more queues. The message is always inside the queue waiting for the consumer to connect to the queue and take it away.
The sending end and the receiving end configure and set a read-write engine of the sending end and the receiving end by using a conventional communication connection, 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 establishes 2 Rabbit MQ message queues serving as channels of bidirectional flow according to communication connection configuration, so that a sending end and a receiving end can use respective corresponding left-direction queues or right-direction queues to monitor messages sent by an opposite side.
In step S202, the receiving end binds the rabbitmq switch to the left queue according to the left routing rule and binds the rabbitmq switch to the right queue according to the right routing rule.
And the read-write engine at the receiving end is actively connected with the Rabbit MQ according to the configuration information, configures the corresponding message queue name and the router and binds the corresponding queue according to the routing rule.
In this embodiment, a sending end, a first receiving end and a second receiving end are used for communication, a left queue is used for the sending end to monitor messages sent by the first receiving end and the second receiving end, a first right queue is used for the first receiving end to monitor the messages sent by the sending end, and a second right queue is used for the second receiving end to monitor the messages sent by the sending end.
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: complete. left, and create a dedicated communication route. After the queue manager of the read-write engine successfully creates the left queue and the right queue, according to a routing rule key: connection.duplex.right.1 binds the first right queue, according to the routing rule key: connection.duplex.right.2 bind the second right queue, key: and binding a left queue by connection.duplex.left, and informing a queue manager of ready initialization so as to realize duplex communication.
In step S203, the receiving end actively sends a handshake message according to the routing rule.
After receiving a ready signal sent by a routing manager, a queue manager of a sending end starts to monitor messages in a left queue, and a first receiving end and a second receiving end respectively use keys: connection.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 queue and the second right queue to receive the messages and pass the key: connection.duplicate.left sends a message to the switch.
And when the queue manager at the sending end monitors that the left queue has information, writing the information into a reading interface of the sending end. When the queue manager at the sending end monitors that the writing interface has information to write, according to the corresponding routing rule key: connection.duplex.right.1 or key: connection.duplex.right.2 sends the information to the exchange of the RabbitMQ.
In step S204, the receiving end listens whether the switch of the RabbitMQ is online.
The communication connection configuration which is appointed to be used by a sending end and a receiving end comprises the following steps: the system comprises a Rabbit MQ address, a user name, a password, a key, a switch to be used during communication, a left queue and a right queue. The switch is used to receive messages sent by message publishers and route the 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 point of the message. A message may be dropped into one or more queues. The message is always in the queue waiting for the consumer to connect to this queue and take it away.
The receiving end sets a read-write engine of the receiving end by using appointed communication connection configuration, and the read-write engine of the receiving end is actively connected with the RabbitMQ according to the configuration information and monitors whether the switchboard of the RabbitMQ is on-line or not. If monitoring the line connection of the Rabbit MQ to the switch, representing that the writing interface of the sending end has information writing, and the information is written into the corresponding routing rule key: connection.duplex.right sends information to the switch of the RabbitMQ, and the switch sends the information to the right-hand queue, at which time the receiver can receive the information by listening to the right-hand queue.
In step S205, when the queue manager of the receiving end detects that information arrives in the right queue, the information is written into the read interface of the receiving end.
The first receiving end and the second receiving end respectively use the first right queue and the second right queue to receive the message of the sending end and pass the key: complete. left sends messages to the switches of rabbitmq, respectively.
When information is written in a write interface of the sending end, the routing rule key corresponding to the information is used for: connection.duplex.right.1 or key: connection.duplex.right.2 sends the information to the switch of the Rabbit MQ, the switch sends the information to the first right queue and the second right queue respectively, at this time, the queue managers of the first receiving end and the second receiving end can both monitor that the corresponding right queue has the information to arrive, and the queue managers of the first receiving end and the second receiving end write the information into the corresponding reading interface.
In step S206, when the queue manager at the receiving end monitors that the information is written in the write interface, the information is sent to the switch of the RabbitMQ according to the corresponding routing rule.
When the information is written in the write-in interface of the first receiving end or the second receiving end, the routing rule key corresponding to the write-in interface is used for: connection.duplex.left sends information to the switch of the Rabbit MQ, the switch sends the information to the left queue, at the moment, the queue manager of the sending end can monitor that the left queue has information to arrive, and the queue manager of the sending end writes the information into the reading interface of the sending end.
