In the system of mechanism, the event of other side is activated between different objects by transmitting message, corresponding operation is completed.Sender
Transmit the message to message server, message server by message deposit in some queues, again by message suitable when
It is transmitted to recipient.Message-oriented middleware can communicate between different platform, it be often used to mask various platforms and agreement it
Between characteristic, realize the collaboration between application program, the advantage is that can provide synchronous and different between client and server
The connection of step, and message can be transmitted or be stored at any time forwarding, this is also that it is adjusted than remote process
With further the reason for.
Message-oriented middleware carries out platform-independent data exchange using the message passing mechanism of high efficient and reliable, and based on data
Communicate with carrying out the integrated of distributed system, by providing message transmission and message queueing model, it can be in distributed environment
Communication between lower extension process.
Thus, before operation flow execution, for ease of carrying out relative recording mark to the operation flow, it can first dispose one
Individual message-oriented middleware, the message-oriented middleware can be that (Redis is that the use increased income an ANSI C language is write, supported to Redis
Network, can based on internal memory also can persistence log type, Key-Value databases, and the API of multilingual is provided) or
(Kafka is that a kind of distributed post of high-throughput subscribes to message system to Kafka, and it can handle the website of consumer's scale
In everything flow data) or other support acknowledgement messagings cancel functions message-oriented middleware.Message-oriented middleware is provided with
Major queue and failure queue, wherein, major queue is for depositing normal record information, and it is different that failure queue execution occurs for storage
Normal record information.

After flow of being engaged in, each execution step of the operation flow, during this, the major queue of message-oriented middleware just can be performed successively
Relative recording information can record " whether each execution step runs succeeded simultaneously" etc. information.Each when the operation flow holds
When row step is performed both by successfully, the major queue of message-oriented middleware deletes relative recording information, or in the relative recording information subscript
Remember that the operation flow is processed into waiting after each execution step of the operation flow is carried out successfully, send response
Information deletes corresponding record information into the major queue of message-oriented middleware by the major queue of message-oriented middleware, or in the phase
Mark the operation flow processed in corresponding record information into.And when any execution step of the operation flow performs failure
When, relative recording information is sent to after the failure queue of message-oriented middleware by the major queue of message-oriented middleware, then carries out related note
Information deletion is recorded, if there is the failure of any one step in that is, whole operation flow implementation procedure, message-oriented middleware
Major queue first writes the relative recording information of the operation flow failure queue of message-oriented middleware, then response message middleware
Major queue, deletes the relative recording information in the major queue of message-oriented middleware.

When handling the failure queue of message-oriented middleware, the relative recording information that can first delete the failure queue of message-oriented middleware is corresponding
The step of operation flow may have been performed, then restart to perform corresponding operation flow, due to the relative recording information
Relative recording can be carried out to the execution of each execution step of the operation flow, according to these relative recordings, it is to be understood that the business
Which the step of flow may have been performed have, now, and the operation that first can be performed these steps is all deleted, so as to weight
It is new to start to perform the operation flow；Also it can directly be restarted to perform corresponding operation flow according to record information, to enter line number
According to covering write-in, that is, the operation flow had performed any step before ignoring, and directly restarted to perform the once business
Flow, to carry out covering write-in to data before.So, just can forming one kind, " performing the operation flow of failure can weigh
The mechanism of new execution, untill the operation flow finally runs succeeded ", consequently, it is possible to just can ensure that each operation flow most
Run succeeded eventually, and then cause flow data finally being consistent property.

Specifically, when operation flow pretreatment module 320 sends a record information into the major queue of message-oriented middleware,
To record after the operation flow that will be performed, operation flow performing module 330 just can perform each of the operation flow successively and hold
Row step, during this, the relative recording information of the major queue of message-oriented middleware can record " each whether to perform step simultaneously
Run succeeded" etc. information.When each execution step of the operation flow is performed both by successfully, the unit 331 that runs succeeded is in host team
Row delete relative recording information, or in relative recording information mark the operation flow processed into waiting the Business Stream
After each execution step of journey is carried out successfully, the unit 331 that runs succeeded can send response message to the master of message-oriented middleware
In queue, and in the message between part major queue on delete corresponding record information, or in the message between part major queue on
Corresponding record information on mark the operation flow processed into.And when any execution step of the operation flow is performed
During failure, performing failure record unit 332 can be transferred to relative recording information in the middle of message from the major queue of message-oriented middleware
The failure queue of part, and in the message between part major queue on delete relative recording information.If i.e. whole operation flow is performed
During when there is the failure of any one step, then performing failure record unit 332 can be first by the relative recording of the operation flow
Information by message-oriented middleware major queue write message-oriented middleware failure queue, then response message middleware major queue, delete
Except the relative recording information in the major queue of message-oriented middleware.
