Sample, for clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.
Fig. 1 is a kind of schematic diagram of the main flow of the method for the anti-frequency of service request according to an embodiment of the present invention, such as Fig. 1
Shown, a kind of method of the anti-frequency of service request of the embodiment of the present invention mainly includes the following steps:
Step S101: the corresponding cache key of current business code is obtained, updates the value of cache key to obtain return value.Pass through
It is preset in service code and explains configuration information, and carry out anti-frequency using configuration information is explained in subsequent treatment process,
To reach technical effect of the invention, overcomes and exist in the prior art because while handling multiple business due to anti-frequency is caused to lose
Effect repeats to write heavy workload caused by rate height and the low problem of the security reliabilities such as network duration occurs.It will caching
The mode that the value+1 of key is handled can be executed using common INCR order.It should be noted that updating the side of the value of cache key
Formula can be the mode for updating the value itself of cache key, for example, obtaining after being handled the value+1 of cache key using INCR order
Return value.It should be pointed out that the value of the cache key in the application is the numerical value returned after handling service code,
Illustrate that the service code is specifically which time is handled；Anti- frequency is the stabilization in order to guarantee service, to need to user
Access times in specific time make restriction scheme.
In embodiments of the present invention, explaining configuration information further includes cache key prefix, obtains current business code pair
The step of cache key answered includes: that the unique identification of the cache key prefix and user that will acquire is spliced, to be cached
Key, wherein the unique identification of user is the unique identification of the user of current business code.The unique identification of user can be using use
ID, the IMS at family and the combination of other forms.
Step S102: return value is compared with anti-frequency number, when determining that return value is greater than anti-frequency number, does not execute industry
Business code.By comparing, it is abnormal to determine that current service code whether there is, if result is that return value is greater than anti-frequency number,
It determines that current service code is abnormal, does not execute the service code；If return value is less than or equal to anti-frequency number, continue to execute described
Service code (namely continuing to carry out the service code abnormal judgement).
In embodiments of the present invention, explaining configuration information further includes the cache key time-to-live, by return value and anti-
Before the step of frequency number is compared further include: judge the size of return value, if return value is equal to 1, survived according to cache key
The validity period of cache key is arranged in time, executes service code；If return value is greater than 1, execute by return value and anti-frequency number into
It the step of row compares, is compared.
Specifically, after determining that return value is greater than anti-frequency number, it is also necessary to which whether the validity period for judging cache key is forever
Long property；If permanent, then throw exception；If not permanent, then number of dishing out transfinites exception.There is message by cache key
To facilitate subsequent be further processed to classifying extremely.
In an embodiment of the present invention, specific processing mode is, when throw exception, to delete cache key and execute business
Code.Certainly, it transfinites exception if number, then recycle time transfinites prompt information.It should be noted that working as in the present invention, throws
When abnormal out, delete cache key and simultaneously execute service code, be only a kind of example, it, can also be with when network timeout or when mistake occurs
It deletes cache key and executes service code.
In an embodiment of the present invention, the process of above-mentioned judgement and comparison is by towards tangent plane programming frame
Spring AOP configuration is realized.It is above-mentioned service code is analyzed and is judged after, just will do it execution step.
Fig. 2 is the flow diagram of the method according to embodiments of the present invention for implementing the anti-frequency of service request, as shown in Fig. 2,
Before starting to illustrate embodiments of the present invention, description below first is made to noun according to the present invention:
Redis: one high performance key-value database memory-based, it is ensured that complications are issued orders execution
Succession.
INCR order in Redis: the corresponding value of key is increased into the value returned after increasing one together, if key is not present, key
Value can first be initialized to 0, then execute again INCR operation.
EXPIRE order in Redis: the expired time for set key.
DEL order in Redis: for deleting already present key.
TTL order in Redis: the remaining expired time of return key in seconds.
SET order in Redis: for specified key setting value and its expired time.
GET command in Redis: for obtaining the value of assignment key.
Spring: being an Open Framework, and Spring is the Java Development Framework of the lightweight risen in 2003,
It is created by Rod Johnson.In simple terms, Spring is JavaSE/EEfullstack (one-stop) lightweight of a layering
Open Framework.
AOP:Aspect Oriented Programming, towards tangent plane programming.The purpose that AOP is mainly realized is to be directed to
Section in business procession extracts, and what it was faced is some step or the stage in treatment process, to be patrolled
During volume between each section lower coupling isolation effect.
It explains: being also metadata.A kind of other explanation of code level.It is JDK1.5 and the spy that later version introduces
Property, and class, interface, to enumerate be in the same level.It can be stated in packet, class, field, method, local variable, method parameter
Deng before, for being illustrated to these elements, annotation.
DDOS: distributed denial of service (Distributed Denial of Service) attack refers to by means of client/clothes
It is engaged in device technology, multiple computers is joined together as Attack Platform, ddos attack is started to one or more targets, from forming
The power of Denial of Service attack is improved again.
Following two step is specifically divided by the process that database Redis is judged in the prior art:
One, it into after the service code method of execution, is obtained in Redis by the GET command in Redis and corresponds to this industry
Value corresponding to the key of business gives an initial value 0 if not having corresponding value in Redis, then will by SET order
This value is stored in Redis, while the expired time of this key is arranged.
Two, judge whether the value that this corresponding service key is obtained in previous step is greater than the maximum number of times of setting, if it is greater than then
Service code is not executed and directly returns to miscue, and the value+1 that otherwise will be obtained in previous step will this corresponding industry by SET order
It is engaged in the value deposit Redis of key, continues to execute service code.
In the application, after certain server receives user's request in Distributed Services, judging request first will be held
Whether capable service code method has note configuration information, can be directly by service code if not explaining configuration information
It is sent to execution module, executes the service code.
If before executing service code, user's request is intercepted with configuration information is explained, prevent into of the invention
Frequency processor module logic, to analyze the service code.
Further, it obtains and explains configuration information (cache key prefix information, cache key time-to-live information, anti-frequency number
Information), cache key prefix information and the unique identification of the user currently logged in are spliced to generate the caching in database Redis
Key, and execute the INCR order of database Redis (INCR order is every, which to be executed, primary can all add the corresponding value of cache key after 1
Return again to), obtain return value.Judge whether return value is 1 (namely judging whether current return value is more than or equal to 1),
Then prove that the cache key is not present before the request if return value is 1, the EXPIRE order setting executed in Redis at this time should
The validity period of cache key is the cache key time-to-live explained in configuration information；It proves if return value is not 1 in request
The preceding cache key has existed and also not out of date, continues to judge whether return value is greater than the anti-frequency number explained in configuration information
Information lets pass this request if return value is less than or equal to anti-frequency number information, if return value is believed greater than anti-frequency number
Breath, then execute the TTL order of database Redis, obtain return value, then further judge whether the validity period of the cache key is forever
(the judge whether return value is -1 (- 1 represent permanent) of long property), be permanently represent program occur exception directly dish out it is different
Often；Cache key is not the cache key time-to-live permanently then proved in anti-frequency control normal program operation and current business code
Already exceed preset anti-frequency number information, number of dishing out transfinites exception.That then collects that anti-frequency processor module dishes out is all
Whether exception information (i.e. comprising above-mentioned throw exception, number of dishing out transfinite exception and system exception), judge Exception Type
It transfinites exception for number, if it (may be that the above-mentioned caching key information analyzed is wrong that Exception Type, which is not that number transfinites abnormal,
Exception accidentally, it is also possible to network timeout or system exception) then prove that graunch occurs for anti-frequency programmed logic, execute Redis
In DEL order the cache key is deleted, continue to execute service code, i.e., mistake occur in anti-frequency component or in the case of exception
Still ensure that service is available；Service code is not executed if Exception Type transfinites exception for number and returns to requester requests time
Count the prompt information that transfinites.
The method of the anti-frequency of service request according to an embodiment of the present invention can be seen that because using adding in service code
Configuration information is explained, and using configuration information is explained come the technological means of anti-frequency, is existed in the prior art so overcoming because same
When handle multiple business and lead to the failure of anti-frequency, repeat to write rate height caused by heavy workload and there is network duration etc.
The low problem of security reliability, and then reach the technical effect for reducing anti-frequency failure and reducing workload, be conducive to improve journey
Sequence development efficiency reduces the workload of programmer.The method of the anti-frequency of service request of the invention when in use, in service code
Set up defences in advance the note configuration information of frequency, specified in explaining configuration information cache key prefix information, cache key time-to-live information,
Anti- frequency number information, it is high-efficient, it is easy to maintain, and absolutely not coupled with service code module.

In:
It obtains module 301 and updates the value of cache key for obtaining the corresponding cache key of current business code to be returned
Value；Processing module 302 when determining that return value is greater than anti-frequency number, is not executed for return value to be compared with anti-frequency number
Service code.Configuration information is explained by presetting in service code, and using explaining configuration information come the technological means of anti-frequency,
And then technical effect of the invention is reached.
Further, explaining configuration information further includes cache key prefix, obtains module and is also used to: the cache key that will acquire
Prefix and the unique identification of user are spliced, to obtain cache key, wherein the unique identification of user is current business code
The unique identification of user.
In embodiments of the present invention further include judgment module (not shown), be used for: judging the size of return value,
If return value is equal to 1, service code is directly executed；If return value is greater than 1, return value and anti-frequency number are compared in execution
