Description
Technical field
The present invention relates to message policies selection technique field, especially a kind of method and dress for realizing synchronous distributing policy
It sets.
Background technique
With the development of SSR business, tactful issues mode diversification, is used under rabbitmq asynchronous message originally
Originating party formula is realized.The requirement of some policy distributions is tightened up, and client synchronization is needed to return to implementing result, and for example distributing policy needs
Client returns to the reception condition of strategy, and executive condition obtains client state etc., if needing to re-issue after failure,
Current mode cannot achieve.
Summary of the invention
The object of the present invention is to provide a kind of method and devices for realizing synchronous distributing policy, not only ensure that synchronism, but also
The efficiency of asynchronous transmission is not lost.
To achieve the above object, the present invention adopts the following technical solutions:
First aspect present invention provides a kind of method for realizing synchronous distributing policy, comprising the following steps:
Universally Unique Identifier is generated according to distributing policy；
An obstruction queue is generated when distributing policy, is put into Hash mapping, key is Universally Unique Identifier；
Message is written in obstruction queue according to Universally Unique Identifier after receiving message；
The message data that key is Universally Unique Identifier is deleted after taking message from obstruction queue.
With reference to first aspect, in a first possible implementation of that first aspect, described generated according to distributing policy is led to
With unique identifier, comprising:
Globally unique Universally Unique Identifier is generated according to distributing policy, is placed on strategy as information identifier register
In message header, the policy message body of json format is generated according to policy message content, is sent in rabbitmq queue.
With reference to first aspect, in a second possible implementation of that first aspect, described to receive after message according to logical
It is write the result into obstruction queue with unique identifier, comprising:
Message queue is returned for client establish and monitor, after receiving message, according to Universally Unique Identifier by message
In the corresponding obstruction queue of data write-in.
With reference to first aspect, in first aspect in the third possible implementation, it is described from obstruction queue take message after
Delete the message data that key is Universally Unique Identifier, comprising:
Message is taken using poll from obstruction queue, if can wait always without message；
If get message deletes the data that key is Universally Unique Identifier from the Hash table of thread-safe.
With reference to first aspect, described to be used from obstruction queue in the 4th kind of possible implementation of first aspect
Poll takes message, if can wait always without message, comprising:
Message is taken using poll from obstruction queue, a time-out time is set as the waiting time, is more than the waiting time
It is not received by message, it is believed that this request fails without response.
Second aspect of the present invention provides a kind of device for realizing synchronous distributing policy, comprising:
Universally Unique Identifier generation module generates Universally Unique Identifier according to distributing policy；
Block queue generation module, an obstruction queue is generated when distributing policy, is put into Hash mapping, key is general
Unique identifier；
Message monitors module, returns to message queue for client and establishes monitoring, after receiving message, according to general unique
Corresponding obstruction queue is written in message data by identification code；
Message takes out module, deletes the message data that key is Universally Unique Identifier after taking message from obstruction queue.
The device of the synchronous distributing policy of the realization of second aspect of the present invention can be realized first aspect and first aspect
Each implementation in method, and obtain identical effect.
The effect provided in summary of the invention is only the effect of embodiment, rather than invents all whole effects, above-mentioned
A technical solution in technical solution have the following advantages that or the utility model has the advantages that
Present invention use is guaranteed the synchronism of message by external program, both guaranteed on the basis of rabbitmq asynchronous transmission
Synchronism, and do not lose the efficiency of asynchronous transmission；A piece of news is uniquely determined using message uuid, message generates when sending；Make
It is realized and is synchronized with obstruction queue；Communication is high-efficient fastly to use rabbitmq as middleware inherently based on the socket of TCP
Communication, it is more high-efficient than traditional http communication mode；The case where high reliablity is not in loss of data relies on rabbitmq
The message queue function of itself ensure that the reliability of message in data transmission.
Detailed description of the invention
Fig. 1 is that the present invention realizes synchronous one flow chart of distributing policy embodiment of the method；
Fig. 2 is that the present invention realizes synchronous two flow chart of distributing policy embodiment of the method；
Fig. 3 is that the present invention realizes synchronous distributing policy apparatus structure schematic diagram.
Specific embodiment
In order to clarify the technical characteristics of the invention, below by specific embodiment, and its attached drawing is combined, to this hair
It is bright to be described in detail.Following disclosure provides many different embodiments or example is used to realize different knots of the invention
Structure.In order to simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.In addition, the present invention can be with
Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated
Relationship between various embodiments and/or setting is discussed.It should be noted that illustrated component is not necessarily to scale in the accompanying drawings
It draws.Present invention omits the descriptions to known assemblies and treatment technology and process to avoid the present invention is unnecessarily limiting.
Embodiment one
As shown in Figure 1, a kind of method for realizing synchronous distributing policy, comprising the following steps:
S1, Universally Unique Identifier is generated according to distributing policy；
An obstruction queue is generated when S2, distributing policy, is put into Hash mapping, key is Universally Unique Identifier；
S3, message is written in obstruction queue according to Universally Unique Identifier after receiving message；
S4, the message data that key is Universally Unique Identifier is deleted after taking message from obstruction queue.
Embodiment two
As shown in Fig. 2, a kind of method for realizing synchronous distributing policy, comprising the following steps:
