Specific embodiment

This specification embodiment provides a kind of fault filling method, device and equipment.

In order to make those skilled in the art more fully understand the technical solution in this specification, below in conjunction with this explanation Attached drawing in book embodiment is clearly and completely described the technical solution in this specification embodiment, it is clear that described Embodiment be only this specification a part of the embodiment, instead of all the embodiments.The embodiment of base in this manual, Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all should belong to The range of this specification protection.

Embodiment one

As shown in Figure 1, this specification embodiment provides a kind of fault filling method, the executing subject of this method can be clothes Business device, wherein the server can be to be made of an independent server, is also possible to the service being made of multiple servers Device cluster etc., which, which can be, provides the server of service for a certain item business or multinomial business, which can use In the one or more operation systems of carrying.This method can be used for judging whether certain operation system has a certain or certain one kind and refer to In the processing such as fault-tolerant ability of fixed abnormal behaviour.This method can specifically include following steps:

In step s 102, the call request of interception target method of servicing includes the destination service side in the call request The mark of method and the numerical value of call parameters.

Wherein, destination service method can be in certain one or more service in any business for solve the problems, such as certain or The method for realizing certain function, destination service method can be created in the application, and be cited elsewhere, target clothes Business method can be by multiple sentences write using predetermined programming language, to solve the problems, such as certain or the step of realizing certain function is Multiple sentences are composed by built-up sequence, and multiple sentences, which are combined, can execute a function or solve the problems, such as a certain Deng.Call request can be to be executed for invocation target method of servicing, to realize the request of certain function.The mark of destination service method Knowledge can be title (i.e. method name) or coding of destination service method of destination service method etc..Call parameters, which can be, to be used for Parameter required for invocation target method of servicing executes.

In an implementation, for internet system, with the continuous promotion of business complexity, amount of access and data volume, before Common monomer applications are gradually split into multiple applications, can pass through Distributed Services between the different application in multiple applications Frame can also pass through the scheduled service that RPC (Remote Procedure Call, remote procedure call) may be implemented Frame carries out communication interaction, to realize the internet system of Service-Oriented Architecture Based.Business dismantling through the above way, can be with So that the complexity of operation system with the dismantling of application (or application system) by cohesion inside each application, also, it is each O&M, capacity planning of application etc. can be carried out independently.At the same time, application process under Service-Oriented Architecture Based itself is ill-mannered The status information of state information, application process can be external into external persistent storage system, such as external can arrive DB In (DataBase, database).

Based on above content, business dismantling can make the application generated have above-mentioned two variation, and then can make The service that primary complete service request has been disassembled at striding course service call tree, as tree node can have following spy Sign: method of servicing can towards interface rather than realize；It the call parameters of method of servicing and returns the result as POJO (Plain Ordinary Java Object, simple Java object), rather than the object of conditioning；Method of servicing be far call rather than It is local to call.

For having accomplished the internet system of Service-Oriented Architecture Based, monitored on line generally directed to servicing: for each clothes Desired indicator (rate that such as reports an error, response time, upstream and downstream data consistency and amount of access) configuration monitoring deep bid of business；For difference Monitoring deep bid can configure different monitoring threshold values, to alarm etc. the exception service method call occurred in system.

And for the validity of monitoring deep bid monitoring, it can usually take the mode of direct fault location to realize, specifically, for The special services of inline system are called, and abnormal behaviour data are injected under special parameter, period, for example, the abnormal row of delay For data, the abnormal behaviour data to report an error or the abnormal behaviour data for distorting parameter values etc..Then, it is infused in abnormal behaviour data After entering, can observe monitoring alarm as a result, to judge to monitor whether deep bid has the ability for finding such abnormal behaviour.

For example, that is, using A and using B, two applications are respectively arranged with clothes as shown in Fig. 2, two applications can be split as Be engaged in interface, in general, in the application may include multiple method of servicing, as using in A including method of servicing 1 and method of servicing 2, Using in B include method of servicing 1 and method of servicing 2 etc., in general, can by into specified services method inject fault data come The fault-tolerant ability for judging whether to have abnormal behaviour is realized, as shown in Fig. 2, can be before the realization logic of original method of servicing Or fault data is injected later.By the processing mode of upper figure it is found that being write due to fault data is in method of servicing realization Portion completes, and new applies generation so that increasing fault type (or failure behavior) newly every time and/or needing when injection condition to issue Code, moreover, the injection of fault data and the realization of method of servicing are indicated by same programming language (such as Java language), And common programming language is procedural programming language, rather than the programming language of descriptionization, express and be meant that " how Do " rather than " what does ", so that the meaning (failure is semantic) of sentence behind can not be embodied in speech level.In addition, above-mentioned Direct fault location logic in processing mode has certain model utility, such as both for special services method, in call parameters number Value and calling time of origin meet to be injected under specified conditions, moreover, the failure of injection generally comprises delay, throws mistake, distorts Three kinds of parameter values etc., in order to solve the above problem existing for direct fault location in method of servicing, this specification embodiment provides one Kind implementation, can specifically include the following contents:

In view of different direct fault location scenes is the various combination for above-mentioned mode, therefore exists and pass through DSL (Domain Specific Language, Domain Specific Language) language is abstracted a possibility that direct fault location logic, meanwhile, consider Fault type to injection can be enumerated, and therefore, fault type can also be abstracted as the syntactic element in DSL language, so that Syntactic element includes that failure is semantic.If direct fault location logic can be expressed by the DSL language of descriptionization, DSL language Grammatical element itself can embody direct fault location semanteme, moreover, fault logic can drive enforcement engine to be infused by DSL Enter, the mode used for explanatory rather than compiled, can make change or update fault type and/or when injection condition without It need to issue and restart and be applied on the line injected, be based on this, failure can be write by DSL language in this specification embodiment and retouched State information.

Specified application can be installed in the terminal device (such as mobile phone, tablet computer or computer) of user, passed through The application can provide one or more different services for user, each service can be real by one or more method of servicing Existing, different functions may be implemented in different method of servicing.When user needs to carry out a certain item operation or a certain using the application When item business, the key provided in application or link etc. can be provided, after getting trigger action, the triggering can be executed Operate corresponding processing logic, wherein may include the calling to certain method of servicing (i.e. destination service method), work as terminal device Determine that title of available destination service method etc. identifies and the number of call parameters when needing invocation target method of servicing Value etc., and the call request of destination service method can be generated based on the information or data of above-mentioned acquisition, and can be by the calling Request is sent to server, at this point, server can intercept the call request.

In step S104, if the mark and call parameters of scheduled target faults description information and destination service method Numerical value match, then to the corresponding target faults injection logic of destination service method injection target faults description information, with true Determine the fail result of performance objective direct fault location logic generation, which includes carrying out the service of direct fault location The numerical value of the mark of method call parameters corresponding with the method for servicing.

Wherein, it is based on above content, target faults description information can be is write by DSL language, target faults description Information can be used for describing needing the case where meeting preset injection condition, patrol certain method of servicing injection direct fault location Volume, to determine the fail result for executing the direct fault location logic and generating, the failure tolerant ability of operation system, failure are judged according to this Fault-tolerant ability may include that whether there is or not self-healing abilities and operation system management whether there is or not the ability for the behavior of noting abnormalities, operation system itself Emergency investigation ability of person etc..Failure-description information does not need operation system and is compiled to it, but can be directly by business Network analysis goes out the mark of method of servicing therein and the numerical value of call parameters and its corresponding target faults injection logic Deng, and execute and target faults injection logic corresponding operation.Target faults injection logic can be by corresponding data come table Sign, then at this point, target faults injection logic can be target faults injection data, which injects tables of data and service is illustrated The mark of method and the numerical value of call parameters etc., and to which method of servicing, any failure is injected under which kind of injection condition (or fault logic) etc., in addition, target faults injection logic can also can be characterized by other to which method of servicing, at what Any way what failure is injected under kind injection condition indicates, for example, pass through flow chart or the logic figure of implementation procedure etc., This specification embodiment does not limit this.

In an implementation, can be believed according to different requirements, by the failure-description that DSL language writes different method of servicing It ceases, may include the mark of different method of servicing and the call parameters of corresponding method of servicing in different failure-description information Numerical value.The failure-description information (i.e. target faults description information) write for interim storage and management can be preset Management system can store it in above-mentioned management system after the completion of by failure-description message composition, and can be by this Management system pushes corresponding failure-description information to corresponding operation system in real time.Operation system receives failure-description letter After breath, which can be analyzed, therefrom the targeted method of servicing of the available failure-description information (that is to say to which method of servicing injection direct fault location logic) injects failure note in what under the conditions of of the method for servicing Entering logic (that is to say the injection condition of direct fault location logic, may include the corresponding call parameters of the method for servicing and its numerical value Deng) and the content of fault logic etc., after obtaining above- mentioned information, above- mentioned information can be stored in the server of operation system In.

It, can be to this after the call request of destination service method is intercepted in the processing of server S102 through the above steps Call request is analyzed, therefrom the numerical value of the mark of available destination service method and call parameters, and then, server can The method of servicing that the mark of destination service method and target faults description information are directed to first is carried out matching comparison, if target The method of servicing that the mark of method of servicing is directed to target faults description information matches, then can further by call parameters and Call parameters and its numerical value in its numerical value and above-mentioned target faults description information carry out matching comparison, if the two match, It can then determine that the target faults description information is the failure-description information for destination service method.If destination service method The method of servicing that is directed to the target faults description information of mark mismatch, and/or, call parameters and its numerical value and above-mentioned mesh The call parameters and its numerical value marked in failure-description information mismatch, then continue to execute the processing of above-mentioned steps S102, that is, continue Other method of servicing are intercepted, and carry out the processing of above-mentioned steps S104.

Target faults description information can be the associated description information for the direct fault location that destination service method needs to carry out, this When, the corresponding target faults injection logic of target faults description information can be injected to destination service method can after the completion of injection To execute the target faults injection logic of injection, pass through the available corresponding failure knot of the target faults injection logic of execution It is corresponding with target faults injection logic can to judge whether server or operation system have by obtained fail result for fruit The fault-tolerant ability of the abnormal behaviour of fault category.If verification passes through, it may indicate that the operation system can continue to use, such as Fruit verification does not pass through, then can modify to operation system, also guarantees the safety of operation system.

It should be noted that in above-mentioned treatment process, it can be according to failure-description information, from the normal call of method of servicing In filter out expectation inject failure (or fault logic) one or many calling carry out direct fault location logic injection, specifically Ground might have a method of servicing and call (such as 10 times or 5 inferior) many times, if merely desire to wherein certain is primary (such as Call parameters meet certain requirement etc.) do failure (or fault logic) injection, then what the failure-description information that DSL writes described can To be how to be selected from above-mentioned multiple calling the method for servicing to call desired that time and inject current calling assorted Failure (or fault logic) etc..

This specification embodiment provides a kind of fault filling method, should by the call request of interception target method of servicing The numerical value of mark and call parameters in call request including destination service method, in scheduled target faults description information and mesh In the case that the numerical value of the mark and call parameters of marking method of servicing matches, to the injection target faults description of destination service method The corresponding target faults injection logic of information, to determine the fail result of performance objective direct fault location logic generation, target faults Description information includes the numerical value for carrying out the mark and the corresponding call parameters of method of servicing of the method for servicing of direct fault location, in this way, Only need the mark and the corresponding tune of method of servicing of the method for servicing by carrying out direct fault location described in failure-description information The information such as the numerical value with parameter can select the method for servicing in operation system, and carry out corresponding target faults note Enter the injection of logic, so that the fail result of performance objective direct fault location logic generation is obtained, without writing above-mentioned progress The numerical value of the corresponding call parameters of mark and method of servicing of the method for servicing of direct fault location and target faults injection logic etc. The related program code of information does not need to carry out the compiled of program code using the server or terminal device of operation system yet Journey enormously simplifies the treatment process of direct fault location, improves direct fault location efficiency.

Embodiment two

As shown in figure 3, this specification embodiment provides a kind of fault filling method, the executing subject of this method can be clothes Business device, wherein the server can be to be made of an independent server, is also possible to the service being made of multiple servers Device cluster etc., which, which can be, provides the server of service for a certain item business or multinomial business, which can use In the one or more operation systems of carrying.This method can be used for judging whether certain operation system has a certain or certain one kind and refer to In the processing such as fault-tolerant ability of fixed abnormal behaviour.This method can specifically include following steps:

As shown in figure 4, in operation system AOP (Aspect Oriented can be passed through to the reference of downstream service Programming, towards tangent plane programming) mechanism determines direct fault location blocker, direct fault location blocker can be used for carrying therefore Barrier description information simultaneously analyzes failure-description information, at the same time it can also be intercepted to the method for servicing that downstream request is called, and it is right Specified method of servicing injection direct fault location logic etc..

In step s 302, the content of target faults description information is analyzed, respectively obtains each critical field pair The content answered.

In an implementation, during injecting direct fault location logic to method of servicing, it is to be understood that the information of three aspects, i.e., Which method of servicing the direct fault location logic (that is to say the targeted method of servicing of failure-description information) is injected, in the clothes to Business method what under the conditions of inject the direct fault location logic and (that is to say the injection condition of direct fault location logic, may include this The corresponding call parameters of method of servicing and its numerical value etc.), and injection fault logic content etc., in this specification embodiment Based on the information of above-mentioned three aspect, failure-description information is write using DSL, the specific syntax can be such that

Dsl:='UPDATE'inject [', ' inject]+' FROM'serviceSignature'WHERE'

expression

Inject:=delay | throw | manipulate

Delay:='DELAY (' time') '

Time:=digit+

Throw:='THROW (' exceptionClassName') '

Manipulate:='MANIPULATE (' paraIdx', ' targetValue') '

ParaIdx:=digit+

TargetValue:=literal

ServiceSignature:=packageName'.'interfaceName'.'methodNa me

Expression:=expression logicOperator expression

|'('expression')'

|paramKey compareOperator literal

LogicOperator:='OR'| ' AND'

CompareOperator:='>' | '<' | '=' | '！='

Literal:=' " ' char+' " '

ParamKey:='['digit+'] " .'OGNL | ' { time } '

Wherein, font is italic but non-overstriking is nonterminal symbol, and font is italic and overstriking is the language of Java language The grammer etc. of method or OGNL (Object-Graph Navigation Language, object diagram navigation language) language, single quotation marks Interior part is character, and remaining part can be terminal symbol etc..

The failure-description information write by above-mentioned DSL can be determined including multiple critical fielies, such as " UPDATE " Field, " FROM " field and " WHERE " field etc., different fields can correspond to different effects, and different field is corresponding Content can be different, as the corresponding content of UPDATE field can be the content of fault logic (or failure), FROM field pair The content answered can be injects (mark etc. that is to say method of servicing) for which method of servicing, and WHERE field is corresponding Content can be call parameters and its numerical value etc..

For example, certain serviced component is realized such as lower interface:

Wherein, AssetDecreaseRequest may include following critical field:

Wherein, the content of above-mentioned multiple critical fielies may refer to following failure-description information are as follows:

UPDATE DELAY(100)

FROM com.alipay.paycore.service.payment.asset.AssetFluxService.decren ent

WHERE [1] .assetExtra [" userId "]=208800000000000000；AND{time}>

'2017-12-3122:01:00'AND{time}>'2017-12-31 22:01:59'。

Above-mentioned failure-description information can be indicated for com.alipay.paycore.service.payment.asset. This method of servicing of AssetFluxService.decrement, in the primary calling to it, the 1st parameter The key of assetExtra field (really a map), i.e. userId correspond to value be equal to ' 2088000000000000', and adjust When with the time between 2017-12-3122:01:00 to 2017-12-31 22:01:59, injection postpones 100 milliseconds of failure (or fault logic) (wherein, it should be noted that for calling every time, need to postpone 100 milliseconds).

The failure-description information of different method of servicing can be write by DSL according to different requirements,.As shown in figure 4, can To preset the management system of failure-description information, after the completion of by failure-description message composition, can store it in It states in management system, and corresponding failure-description information can be pushed to corresponding operation system by the management system in real time. After operation system receives the failure-description information, which can be analyzed, can therefrom be respectively obtained UPDATE field, FROM field and the corresponding content of WHERE field.Based on above-mentioned example, available UPDATE field is corresponding Content be DELAY (100), the corresponding content of FROM field be com.alipay.paycore.service.payment.ass The corresponding content of et.AssetFluxService.decrenent, WHERE field be [1] .assetExtra [" userId "]= 208800000000000000；AND{time}>'2017-12-3122:01:00'AND{time}>'2017-12-31 22:01: 59'.Above content correspondence can be stored in the server of operation system.

It should be noted that the failure-description information write by DSL does not need operation system and is compiled to it, but The mark of method of servicing therein and the numerical value of call parameters, and corresponding failure note can be directly analyzed by operation system Enter logic etc., and executes and the direct fault location logic corresponding operation.

In addition, the critical field for including in failure-description information is not limited to UPDATE field mentioned above, FROM word Section and WHERE field etc. can also include in practical applications a variety of other critical fielies, can specifically set according to the actual situation It is fixed, it is not limited this in this specification embodiment.

In step s 304, the call request of interception target method of servicing includes destination service method in the call request Mark and call parameters numerical value.

In an implementation, as shown in figure 4, when the method for servicing (i.e. destination service method) that downstream relies on needs called, Downstream can send call request to operation system can be by direct fault location blocker institute after the call request reaches operation system It intercepts, to intercept the call request of destination service method, wherein may include destination service method in the call request The numerical value of mark and call parameters.

In step S306, if the mark and call parameters of scheduled target faults description information and destination service method Numerical value match, then the corresponding fault type of target faults injection logic is obtained, before which includes preposition class and is non- Set class.

Wherein, target faults description information can be is write by Domain Specific Language DSL.In target faults description information It may include multiple critical fielies, and multiple critical fielies are respectively used to the corresponding method of servicing of characterization target faults description information Mark and call parameters numerical value.Multiple critical fielies of target faults description information respectively can for FROM, WHERE and UPDATE etc..In addition, the critical field for including in failure-description information is not limited to UPDATE field mentioned above, FROM word Section and WHERE field etc. can also include in practical applications a variety of other critical fielies, can specifically set according to the actual situation It is fixed, it is not limited this in this specification embodiment.

In an implementation, since failure usually may include preposition class failure and non-preposition class failure, rather than preposition class failure Fail result can not usually be showed to user or technical staff, and be only in operation system internal record, therefore, before non- It sets class failure and possibly can not directly obtain corresponding direct viewing fault as a result, for this purpose, in this specification embodiment, it can be only to failure Type is the injection that preposition class failure carries out direct fault location logic, therefore, to the injection target faults injection of destination service method Before logic, the corresponding fault type of target faults injection logic can be obtained from target faults description information, alternatively, can be with By preassign etc. modes determine the corresponding fault type of target faults injection logic, and judge the fault type whether be before Class is set, if it is not, then original destination service method logic can be executed with invocation target method of servicing, it is corresponding to realize Function.

It should be noted that if the method for servicing that the mark of destination service method is directed to the target faults description information It mismatches, and/or, call parameters and its call parameters and its numerical value mismatch in numerical value and above-mentioned failure-description information, then Original destination service method logic can be executed with invocation target method of servicing, to realize corresponding function, meanwhile, Ke Yiji The continuous processing for executing above-mentioned steps S304, that is, continue to intercept other method of servicing.

In step S308, if above-mentioned fault type is preposition class, destination service method injection target faults are retouched State the corresponding target faults injection logic of information.

In an implementation, as shown in figure 4, if the processing of S306 determines that target faults injection logic is corresponding through the above steps Fault type is preposition class, then can inject target faults injection logic to destination service method, after the completion of injection, can execute The target faults injection logic of injection can be with by the available corresponding fail result of the target faults injection logic of execution Obtained fail result is recorded in serve log (such as log file etc.).When user or technical staff need to check it is above-mentioned When fail result, corresponding serve log can be obtained by monitoring system, and can be obtained from the serve log corresponding Fail result can judge whether server or operation system have and target faults injection logic by obtained fail result The fault-tolerant ability of the abnormal behaviour of corresponding fault category.If verification passes through, it may indicate that the operation system can continue It uses, if verification does not pass through, operation system can be modified, also guarantee the safety of operation system.
