Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application
A part of the embodiment, instead of all the embodiments.Based on this specification embodiment, those of ordinary skill in the art are not making
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present application.
Embodiments herein is further described in conjunction with attached drawing.
As shown in Figure 1, for the processing of service request in a kind of distributed type assemblies for providing of one embodiment of this specification
The flow diagram of method, method includes the following steps:
Before carrying out the method, first configuring request white list is needed, request white list configures in request agency module,
By the service request configuration for needing to handle by this method in request white list, the service request in the present embodiment is that request is white
Service request in list.The purpose of the step is the service request that selection needs to carry out this method, does not need to execute this method
Service request no longer request in white list, can guarantee in this way request white list in service request by execute this method
A service request, which may be implemented, to be executed by physical node, from without a service request by multiple physics
The case where node execution leads to error.The service request in request white list is not executed by the prior art.The step
It is equivalent to and judges whether service request is the service request requested in white list, if so, executing this method.If it is not, then
Do not execute this method.
Step S100 establishes service request and logical node according to the information of the information of service request and logical node
First mapping relations, the first mapping relations are the corresponding logical node of a service request, and a logical node is one corresponding
The above service request.Physical node can be the execution units such as server, physical terminal machine, logical node in the present embodiment
It is the intermediate tie for playing function served as bridge abstracted in the present embodiment as between service request and physical node, logic section
Point can be an intermediate file, and service request is assigned to corresponding physical node by logical node and is executed.
The step specifically includes:
It is calculated by parameter of the preset computation rule to service request.Include in each service request and the request
Corresponding parameter information, certain information in customized selection parameter information are handled as needed, in the present embodiment, can
To be that user identity proves (UID), process identity mark (PID) etc., the parameter of different service requests may be different.It is default
Computation rule can be hash algorithm, by hash algorithm in service request parameter key value carry out Hash calculation, tool
The calculation of the hash algorithm of body be equally can according to need carry out it is customized, select in the present embodiment be choose
Inverse the 2nd, 3 calculation method as Hash that user identity proves, inverse 1,2 for choosing process identity mark are used as Kazakhstan
Uncommon calculation method.It is corresponding with the number of logical node after the parameter key value of service request is calculated by hash algorithm
, the result after the parameter key value of a service request is calculated by hash algorithm can be with the number of a logical node
It is corresponding.Certainly it is also an option that other Hash calculation methods calculate the parameter key value of service request.Service is asked
The parameter key value asked is can be with the parameter key value of the unique identification service request.
The result of calculating is matched with the number of logical node, establishes the first mapping of service request and logical node
Relationship.Logical node is that have certain number, and logical node is numbered according to the title of logical node and address, such as
There are 100 logical nodes, this hundred logical nodes can be numbered according to the title and address of logical node, from 00
To 99.The parameter of service request by hash algorithm calculate after obtain result be with the number of logical node can be corresponding,
That is the number that the parameter of each service request has a logical node by hash algorithm calculating later is corresponding.
Service request is matched with logical node thus, establishes the first mapping relations of service request and logical node.No
Same service request can be different Hash calculation methods, be selected according to service request and the information of logical node corresponding
Hash calculation method, further establish the first mapping relations between the two.
Multiple and different service requests may obtain identical knot after above-mentioned hash algorithm calculating parameter key value
Fruit, the corresponding same logical node, that is, multiple service requests can map the same logical node, be not a logic section
Point can only correspond to a service request.
It is worth noting that further including the steps that the information for obtaining logical node before executing the step.It is patrolled in acquisition
It just can establish the first mapping relations between service request and logical node after the information of volume node.The step, which can be, is asking
Proxy module starting is asked to carry out when requesting.
Step S200 establishes physical node and logical node according to the information of the information of physical node and logical node
Second mapping relations, the second mapping relations are one-to-one relationship.Physical node is mapped in logical node one by one, one
Physical node maps a logical node, the Universally Unique Identifier (UUID) of physical node is written in logical node, UUID
It can be and generated according to the address Mac of server network interface card.Include in logical node physical node Universally Unique Identifier it
Afterwards, illustrate that this logical node physical node corresponding with this Universally Unique Identifier establishes mapping relations.Decision logic
When whether having had existed Universally Unique Identifier in node, sentenced by the logical group management module where logical node
It is disconnected, it include logical node in logical group management module, logical node can regard one in logical group management module as
A file.Logical group management module has lock mechanism, and the process of mapping relations is established between physical node and logical node
In, the one-to-one correspondence between logical node and physical node can be guaranteed by lock mechanism, that is, guarantee a logic section
Point can only correspond to a physical node, and the Universally Unique Identifier of a physical node can only be saved in a logical node.But
It is that when the corresponding physical node of logical node can send change, such as physical node damage, physics section can be replaced
Point, physical node and logical node or one-to-one relationship after replacement.
The corresponding physical node of one logical node, when physical node changes, saved in logical node it
The Universally Unique Identifier of preceding physical node also needs to be changed, physics after changing several points it is general unique
Identification code write-in is without in the logical node of corresponding newest physical node.Newest physical node refers to general unique identification
Code physical node identical with the Universally Unique Identifier saved in logical node.There is no coupling between physical node and service request
Conjunction relationship, that is to say, that decoupled service request and physical node by logical node in the technical solution of the application, often
The corresponding unique logical node of a physical node, physical node is that do not have unique corresponding relation directly with service request
's.It, can be corresponding by logical node when physical node corresponding with logical node changes (such as situations such as damage)
Physical node is replaced or is updated, and physical node can be changed flexibly.
The second mapping relations in the step are established during physical node starting.
Step S300, using first mapping relations and the second mapping relations, by the service request and the physics
Node is associated, by having the physical node of second mapping relations to execute and the logic section with the logical node
Point has the service request of first mapping relations, to complete the processing to service request in distributed type assemblies.
Before service request and physical node are associated further include: request agency module is to logical group management module
The information of logical node is subscribed to, whether logical group management module decision logic node changes, when logical node becomes
When change, logical group management module sends update notification to request agency module, and request agency module logic node is prompted to occur
Variation, request agency module receive the logical node after update notification after more new change.Such as when logical node has increase,
Need to subscribe to the information of the logical node after increasing.Only in logical node, logical group management module will be patrolled after changing
The change information of volume node is sent to request agency module, request agency module by the logical node information after received variation into
Logical node after row caching, service request and variation establishes mapping relations.Subscribe to logical node information purpose be in order to
Request agency module, that is, client does not have to per the full dose logical node letter pulled in logical group management module at regular intervals
Breath, further improves the working efficiency of request agency module, improves the performance of request agency module.
When the service request initiates call request, the corresponding logical node of the service request is called；The service is asked
Corresponding logical node is asked to call physical node corresponding with the service request, logical node pair corresponding with this service request
The physical node answered judges the Universally Unique Identifier of its own and has with it logical in logical node of the second mapping relations
It is whether consistent with unique identifier.When the two is consistent, the corresponding physical node of the logical node to current service request into
Row processing；Otherwise, this physical node is not handled current service request, and physical node with it by having second to reflect
The information not handled current service request is sent to request agency module by the logical node for penetrating relationship.Work as physical node
After the information for receiving logical node, whether the Universally Unique Identifier in decision logic node is general with physical node itself
Unique identifier is consistent.When consistent, physical node execute service request, otherwise do not execute and by the information not executed by with
Its corresponding logical node is sent to request agency module, and request agency module decides whether to re-start calling as needed
Request.When there is inconsistency, illustrate that physical node is changed, such as physical node there is a problem, after changing
The information of physical node updates in logical node not yet.The general unique identification of physical node after needing to change at this time
In code information update to logical node not corresponding with original physical node, one of physical node and logical node after establishing variation
One-to-one correspondence.
Logical node save physical node Universally Unique Identifier after, the information of logical node include title,
The Universally Unique Identifier of location and physical node.
Wherein, a side of service requester and subscription logical node information is client, process of the client in starting
The middle information for subscribing to all logical nodes, for logical node after changing, client will be updated the information of logical node,
That is the subscription of service request and logical message executes in the client.Equally, judge whether service request asks
Asking the request in white list is also to execute in the client.Physical node in the embodiment of the present application is in physical node management
In module, logical node is in logical group management module, and client can be service request proxy module.With reference to Fig. 2.
The embodiment of the present application provides a kind of processing method of Distributed Services request, by creating for each physical node
One unique logical node realizes physical node and the decoupling that service request is called, so that the corresponding physical node of logical node
Be it is stateless (the corresponding physical node of a logical node only one, but the corresponding physical node of this logical node
Can replace), so that physical node can be changed flexibly；It is to have shape between the calling and logical node of service request
State (namely a service request can only correspond to some logical node, this logical node cannot change, and be equivalent to one
Service request and some logical node are bound, but can only be bound with a service request not equal to this logical node, one
A logical node can be to a reply service request), the service request of user can be distributed in fixed logical node, thus
The calling and treatment process for guaranteeing service request can guarantee the serialization write.It ensure that a service request can only be by an object
It manages node to execute or handle, solves a service request and handled mistake occur by multiple physical nodes under stateless
Technical problem.
Meanwhile embodiments herein provide processing method also solve service request where service request act on behalf of mould
Block has the function of logical group management module simultaneously, directly corresponding with physical node, that is, is calling directly physical node
When, it needs to establish the mapping relations with physical node and increase and decrease, the update etc. for needing to read or safeguard physical node operates,
The very big problem of caused service request proxy module workload.The task of service request proxy module is simplified, so that in reality
Using effect in the application of border is more preferable.
The service request in request white list not can be used the prior art and carry out random process.
Present invention also provides a kind of embodiment of concrete application scene, the application scenarios can be mail intelligent recommendation,
The scene of the functions such as contact person's search.It is illustrated for the application scenarios of one mail intelligent recommendation of the present embodiment.
Intelligent recommendation function in mail is according to information such as the good friends for sending and receiving, contacting of history mail of user
User information retrieval database is set up, when user scans for, user is pushed to most according to user information retrieval database
It is possible that interested content (such as addressee etc.).Since this functionality is constructed according to the historical data of user,
The searching database for needing to construct oneself for each user realizes that upper by the construction database sharing of each user is one in system
A file, is stored in distributed file system, and the building of this retrieval file is increment type building.When user often receives one
When sealing mail, which will be parsed, then relevant information is added in the user information retrieval database of foundation,
The original corresponding file of user information retrieval database can thus be modified.Such user information retrieval database is corresponding
The write operation of file is if there is parallel when the enterprising row write of multiple servers operates, it is more likely that will lead to data entanglement, shadow
Normal service function is rung, so to guarantee the serialization processing of retrieval file building, that is, user information retrieval database
The write operation of corresponding file can only be executed in a server.
In order to solve the problems, such as above-mentioned file write operation it is possible that the case where, in building user information retrieval database
When, to the calling of building service request, we can be in the white list of request agency module configuration service request, mark service
Request is to need to carry out the service request of stateful processing.When a service start request, whether this service request is judged
For the service request in service request white list, if it is, carrying out the method in embodiments herein.Where service request
Client (request agency module) information that pulls logical node, by service request by scheduled algorithm in service request
Parameter key value calculated, the result of calculating is matched with the number of logical node, establishes service request and logic section
The first mapping relations between point.The number of logical node is editted before carrying out the first mapping relations.Service request
Call logical node that there are the first mapping relations with it, service request and logical node are stateful, that is, clothes
Business request can only correspond to a logical node, this logical node cannot change, but a logical node can correspond to it is multiple
Service request.Physical node is established on startup and the second mapping relations of logical node, between physical node and logical node
The second mapping relations be stateless, that is, the corresponding logical node of physical node, but logical node is corresponding
Physical node can change.After logical node receives the calling of service request, calling with logical node there is the second mapping to close
The physical node of system, Universally Unique Identifier in physical node decision logic node whether be oneself itself general unique knowledge
Other code, if it is, executing service request.Otherwise it does not execute.Above-mentioned steps are re-executed, until can execute.
Embodiment provided by the present application can guarantee that the service request for having the first mapping relations with logical node can be only
It is handled by a physical node, solves the problems of the prior art.
The above method realizes the processing to service request, solve in the prior art a service request by multiple physics
Node executes the problem for mistake occur, has reached corresponding technical effect, this specification embodiment also provides a kind of realization
