S10, constructing a bill removing plug-in, and subscribing the report message of a report Service assembly (ORS) through the bill removing plug-in.
In this embodiment, the drop card is a separate component or module.
In this embodiment, the offer service component is configured to offer to an exchange.
In this embodiment, the report message refers to a message issued by a transaction and used for representing a transaction status of an order (e.g., a transaction success, an order to be cancelled, a transaction failure, etc.).
In this embodiment, the subscribing, by the revocation plugin, the report message of the report service component includes:
calling a specified application program interface through a configuration protocol;
connecting to preset message middleware through the application program interface;
and sending a request for subscribing the report message to the report service component through the preset message middleware.
The configuration protocol refers to a communication protocol agreed between the ticket withdrawing plug-in and the report service component.
Wherein, the appointed application program interface is used for realizing the interaction between the order withdrawing plug-in and the report service component.
The preset message middleware is used for realizing data transmission between the order withdrawing plugin and the report service component, and is a message bus.
The receipt removing plug-in operates independently, passively receives the return message sent by the report service component to the core transaction, is completely decoupled from other components (such as an access gateway, a market gateway, and a TE (transaction Engine) core transaction), and only needs to use a small amount of bandwidth for data transmission through the preset message middleware, and the subscribed return message is that the report service component needs to be sent to the transaction core without additional processing, so that the receipt removing plug-in can neglect the influence on the transaction system under normal conditions, and cannot generate additional influence on the system, such as report delay, system resource occupation and other problems.
S11, when the order withdrawing plug-in receives the return message issued by the report service component, establishing a withdrawable order list in the order withdrawing plug-in according to the received return message.
In this embodiment, the establishing, in the order withdrawing plugin according to the received reward message, a withdrawable order list includes:
when the state of the received return message is accepted by a transaction bureau, acquiring a preset field of the received return message in the bill withdrawing plugin;
maintaining the preset field to a form to obtain the removable order list;
when detecting that the state of the return message in the removable order list is a committed order, a removed order or a transaction failure, determining the order corresponding to the detected return message as a completed order, and deleting the detected return message from the removable order list.
The corresponding return message may be analyzed according to the message headers, the message numbers, and the like of different return messages, so as to obtain the preset field of the received return message. For example: the preset field may be a combination of fields representing information such as the number of the tickets, the price of the tickets, the contract number, etc.
When the state of the report message is committed or removed or the transaction fails, the corresponding transaction is completed, and the order is not required to be removed and is not recorded in the removable order list, so that data redundancy is avoided and the accuracy of the order removal is not influenced.
And S12, when the transaction system fault is detected and the order withdrawing plug-in is started, the order withdrawing plug-in is informed to be connected with a transaction gateway, and a message return breakpoint in the order withdrawing list is obtained.
In this embodiment, it is first required to determine whether the transaction system fails and whether the receipt removing plug-in is activated, and specifically, the method further includes:
when detecting that the transaction system generates error reporting information, determining that the transaction system has a fault and sending alarm information;
and when a starting instruction for the order removing plug-in is received, starting the order removing plug-in.
Specifically, the error reporting information may be displayed on an interface of the operation and maintenance management system, and the alarm information may be sent to prompt a relevant worker (such as an operator) to perform timely processing. When the operator determines that the transaction system is in a fault and needs to start the order removing plug-in, the operator may trigger a relevant key or input a voice instruction and the like on an interface of the operation and maintenance management system to trigger a start instruction for the order removing plug-in, and at this time, the order removing plug-in is started.
In this embodiment, when notifying that the revocation plugin is connected to the transaction gateway, the method further includes:
when the quotation service component is not abnormal and is in a connection state with the transaction gateway, informing the quotation service component to disconnect the connection with the transaction gateway, acquiring an account number used by the quotation service component to connect with the transaction gateway, feeding the account number back to the receipt removing plug-in, and after the quotation service component is disconnected with the transaction gateway, informing the receipt removing plug-in to establish connection with the transaction gateway by using the account number; or alternatively
When the quotation service component is abnormal and is in a disconnected state with the transaction gateway, an account number used by the quotation service component for connecting with the transaction gateway is obtained, the account number is fed back to the order removing plug-in, and the order removing plug-in is informed to establish connection with the transaction gateway by using the account number.
In the embodiment, the same account number is adopted to establish connection with the transaction gateway, so that the problem of inconsistent data can be effectively avoided, and the result of withdrawing the unions is more accurate.
In addition, because the same account number is used for establishing connection with the transaction gateway, the connection between the ticket withdrawal plugin and the transaction gateway can be established only by disconnecting the connection between the ticket reporting service component and the transaction gateway.
Further, a message return breakpoint in the withdrawable order list is obtained. For example: when there are 100 return messages in the withdrawable order list, the sequence number of the 100 th return message is obtained and used as the message return breakpoint.
And S13, after the order withdrawing plug-in is successfully connected with the transaction gateway, pulling a return message to the transaction gateway according to the message return breakpoint.
It can be understood that, after the transaction system fails, it is likely that some report messages are not successfully issued, and therefore, in order to ensure that no order is missed, a report message needs to be pulled to the transaction gateway according to the message report breakpoint.
Specifically, the pulling the report message to the transaction gateway according to the message report breakpoint includes:
detecting whether a return message which is not maintained in the removable order list exists in the transaction gateway or not according to the message return breakpoint;
pulling the detected reward message to the transaction gateway.
For example: when the message reporting breakpoint is serial number 100, it may be detected from serial number 101 whether there is a reporting message that is not maintained in the removable order list in the transaction gateway, and if the reporting message with serial numbers 101 to 105 is not maintained in the removable order list, the reporting message with serial numbers 101 to 105 is pulled to the transaction gateway.
By pulling the return message which is issued but not maintained in the order-withdrawing list, the return message can be effectively prevented from being omitted, and the problem of losing the order when withdrawing the order is further avoided.
And S14, updating the removable order list according to the pulled return message to obtain the target removable order.
For example: and after the return message with the sequence number of 101-105 is pulled to the transaction gateway, updating the return message with the sequence number of 101-105 to the withdrawable order list in an increment mode, so that the target withdrawable order is the order corresponding to the return message with the sequence number of 001-105.
And S15, generating a withdrawing request according to the target withdrawing order.
The order withdrawing request is a request aiming at the target removable order so as to withdraw the trading order in a targeted manner.
And S16, when the target removable orders are all successfully removed, disconnecting the connection between the removal plug-in and the transaction gateway, and recovering the transaction system.
When the target withdrawable orders are successfully withdrawn, the connection between the order withdrawing plug-in and the transaction gateway is disconnected, so that the connection can be released, and the listing service component can be reconnected with the transaction gateway.
In this embodiment, the recovering the transaction system includes:
when the report service component is not abnormal, informing the report service component to reconnect the transaction gateway;
after the report service component is reconnected with the transaction gateway, a report message is pulled back to the transaction gateway through the report service component, and a report withdrawing result is updated to a Transaction Engine (TE) according to the pulled report message.
The failure of the transaction system may be caused by various reasons, such as failure of a transaction gateway, failure of a transaction engine, or failure of an inventory service component. Only when the report service component is not abnormal, the report service component can be informed to automatically reconnect the transaction gateway, and when the report service component is abnormal, the report service component needs related staff to perform manual recovery.
In addition, in the conventional manner, account checking synchronization is required after closing and clearing, and in this embodiment, after the transaction system is restored to normal, the offer service component is reconnected to the transaction gateway to pull an offer and synchronize the order status to the core transaction, so as to realize active update and restoration of the system resource ticket status.
It can be seen from the above technical solutions that, the present invention can construct a revocation list plugin, subscribe a reward message of a newspaper service component through the revocation list plugin, when the revocation list plugin receives a reward message issued by the newspaper service component, establish a revocation order list in the revocation list plugin according to the received reward message, when a transaction system failure is detected and the revocation list plugin is started, notify the revocation list plugin to connect a transaction gateway and obtain a message reward breakpoint in the revocation order list, after the revocation list plugin is successfully connected with the transaction gateway, pull the reward message to the transaction gateway according to the message reward breakpoint, update the revocation order list according to the pulled reward message, obtain a target revocation order, generate a revocation request according to the target revocation order, and when the target revocation order is successfully revoked, disconnect the connection between the revocation list plugin and the transaction gateway and restore the transaction system. By utilizing the invention, when the transaction system fails, the order can be timely removed based on the constructed independent order removing plug-in, and the order loss is effectively avoided.
Fig. 2 is a functional block diagram of a preferred embodiment of the transaction system failure de-ordering device according to the present invention. The transaction system failure revocation device 11 includes a subscription unit 110, an establishment unit 111, a notification unit 112, a pulling unit 113, an updating unit 114, a generation unit 115, and a recovery unit 116. A module/unit as referred to herein is a series of computer program segments stored in a memory that can be executed by a processor and that can perform a fixed function. In the present embodiment, the functions of the modules/units will be described in detail in the following embodiments.
The subscribing unit 110 constructs a revocation list plugin and subscribes a report message of an offer Service component (ORS) through the revocation list plugin.
In this embodiment, the singleton plugin is a stand-alone component or module.
In this embodiment, the offer service component is configured to offer to an exchange.
In this embodiment, the report message refers to a message issued by a transaction and used for representing a transaction status of an order (e.g., a transaction success, an order to be cancelled, a transaction failure, etc.).
In this embodiment, the subscribing unit 110 subscribes to the reward message of the reward service component through the revocation plugin, and includes:
calling a specified application program interface through a configuration protocol;
connecting to preset message middleware through the application program interface;
and sending a request for subscribing the report message to the report service component through the preset message middleware.
The configuration protocol refers to a communication protocol agreed between the ticket withdrawing plug-in and the report service component.
Wherein, the appointed application program interface is used for realizing the interaction between the order withdrawing plug-in and the report service component.
The preset message middleware is used for realizing data transmission between the bill removing plug-in and the report service component, and is a message bus.
The receipt removing plug-in operates independently, passively receives the return message sent by the report service component to the core transaction, is completely decoupled from other components (such as an access gateway, a market gateway, and a TE (transaction Engine) core transaction), and only needs to use a small amount of bandwidth for data transmission through the preset message middleware, and the subscribed return message is that the report service component needs to be sent to the transaction core without additional processing, so that the receipt removing plug-in can neglect the influence on the transaction system under normal conditions, and cannot generate additional influence on the system, such as report delay, system resource occupation and other problems.
When the order removing plug-in receives the report message issued by the report service component, the establishing unit 111 establishes a removable order list in the order removing plug-in according to the received report message.
In this embodiment, the establishing unit 111, in the withdrawing order plugin, establishing the withdrawable order list according to the received reward message includes:
when the state of the received return message is accepted by a transaction institute, acquiring a preset field of the received return message in the receipt removing plug-in;
maintaining the preset field to a form to obtain the removable order list;
when detecting that the state of the return message in the removable order list is transaction completion, or withdrawal, or transaction failure, determining the order corresponding to the detected return message as a completed order, and deleting the detected return message from the removable order list.
The corresponding return message can be analyzed according to the message headers, the message numbers and the like of different return messages, so as to obtain the preset field of the received return message. For example: the preset field may be a combination of fields representing information such as the number of the tickets, the price of the tickets, the contract number, etc.
When the state of the return message is committed or removed or the transaction fails, the corresponding transaction is completed, and the order is not required to be removed and is not recorded in the removable order list, so that data redundancy is avoided and the accuracy of order removal is not influenced.
When a transaction system failure is detected and the withdrawing plug-in is activated, the notification unit 112 notifies the withdrawing plug-in to connect to the transaction gateway and obtains a message return breakpoint in the withdrawable order list.
In this embodiment, it is first necessary to determine whether a transaction system fails and whether the receipt removing plug-in is started, specifically, when it is detected that the transaction system generates an error report message, it is determined that the transaction system fails, and an alarm message is sent;
and when a starting instruction for the order removing plug-in is received, starting the order removing plug-in.
Specifically, the error reporting information may be displayed on an interface of the operation and maintenance management system, and the alarm information may be sent to prompt a relevant worker (such as an operator) to perform timely processing. When the operator determines that the transaction system is in failure and needs to start the order removing plug-in, the operator may trigger a related key or input a voice instruction and the like on an interface of the operation and maintenance management system to trigger a start instruction for the order removing plug-in, and at this time, the order removing plug-in is started.
In this embodiment, when the receipt removing plug-in is notified to connect to a transaction gateway, when the offer service component is not abnormal and is in a connection state with the transaction gateway, the offer service component is notified to disconnect from the transaction gateway, an account number used by the offer service component for connecting with the transaction gateway is obtained, the account number is fed back to the receipt removing plug-in, and when the offer service component is disconnected from the transaction gateway, the receipt removing plug-in is notified to establish a connection with the transaction gateway by using the account number; or
When the offer service component is abnormal and is in a disconnected state with the transaction gateway, an account number used by the offer service component to be connected with the transaction gateway is obtained, the account number is fed back to the order withdrawing plugin, and the order withdrawing plugin is informed to establish connection with the transaction gateway by using the account number.
In the embodiment, the same account number is adopted to establish connection with the transaction gateway, so that the problem of inconsistent data can be effectively avoided, and the result of withdrawing the unions is more accurate.
In addition, because the same account number is used for establishing connection with the transaction gateway, the connection between the ticket withdrawal plug-in and the transaction gateway can be established only by disconnecting the connection between the ticket reporting service component and the transaction gateway.
Further, a message reward breakpoint in the withdrawable order list is obtained. For example: when there are 100 return messages in the withdrawable order list, the sequence number of the 100 th return message is obtained and used as the message return breakpoint.
After the receipt removing plug-in is successfully connected to the transaction gateway, the pulling unit 113 pulls a report message to the transaction gateway according to the message report breakpoint.
It can be understood that, after the transaction system fails, it is likely that some reward messages are not successfully issued, and therefore, in order to ensure that no order is missed to be cancelled, a reward message needs to be pulled to the transaction gateway according to the message reward breakpoint.
Specifically, the pulling unit 113 pulling the reward message to the transaction gateway according to the message reward breakpoint includes:
detecting whether a return message which is not maintained in the removable order list exists in the transaction gateway according to the message return breakpoint;
pulling the detected reward message to the transaction gateway.
For example: when the message reporting breakpoint is sequence number 100, it may be detected from sequence number 101 whether a reporting message that is not maintained in the removable order list exists in the transaction gateway, and if the reporting message with sequence numbers 101 to 105 is not maintained in the removable order list, the reporting message with sequence numbers 101 to 105 is pulled to the transaction gateway.
By pulling the return message which is issued but not maintained in the order-withdrawing list, the return message can be effectively prevented from being omitted, and the problem of losing the order when withdrawing the order is further avoided.
The updating unit 114 updates the removable order list according to the pulled report message, so as to obtain the target removable order.
For example: and after the return message with the sequence number of 101-105 is pulled from the transaction gateway, updating the return message increment with the sequence number of 101-105 to the withdrawable order list, so that the target withdrawable order is an order corresponding to the return message with the sequence number of 001-105.
The generating unit 115 generates a form removing request according to the target removable form.
The order withdrawing request is a request aiming at the target removable order, so that the trade order can be withdrawn in a targeted manner.
When all the target removable orders are successfully removed, the recovery unit 116 disconnects the removal plug-in from the trading gateway and recovers the trading system.
When the target removable orders are successfully removed, the connection between the removal plug-in and the transaction gateway can be released by disconnecting the removal plug-in, so that the report service component can be reconnected with the transaction gateway.
In this embodiment, the recovering unit 116 recovering the transaction system includes:
when the report service component is not abnormal, informing the report service component to reconnect the transaction gateway;
after the report service component is reconnected with the transaction gateway, a report message is pulled back to the transaction gateway through the report service component, and a report withdrawing result is updated to a Transaction Engine (TE) according to the pulled report message.
