Fig. 1 is a kind of schematic diagram of the management method key step of regular text according to embodiments of the present invention.
As shown in Figure 1, a kind of key step of the management method of regular text of the embodiment of the present invention includes：
S11：Server obtains regular text, and obtains the parameter object list that regular text operation needs.
After the list object that gets parms, parameter object list is put into context (Context)；And upper and lower
Dynamic queries are provided in text.The parameter list can be full dose, will and the relevant parameter object of the business be all put into up and down
Wen Zhong；It can also dynamically specify, i.e., corresponding parameter object is passed to by upper strata called side.It generally all can be in context pair
As middle offer dynamic query method, dynamic query method refers to through the parameter key in regular text, i.e. Key, Ke Yitong
It crosses the dynamic query method and inquires corresponding Value values within a context.It is to be identified by corresponding object entity, dynamic
The object entity is inquired, includes and uses in context, not comprising then inquiring.Also, the form of context is set as Key-
Value forms, i.e. form are [key, bean].Parameter list forms the set of Key, a Value, can be obtained by Key
To corresponding Value values.Fig. 3 is the context entity of system, i.e., when system is literary regular in commission, needs cut-and-dried ginseng
Number object entity class, such as [order, order] the i.e. mapping relations of [key, value] can be got corresponding below by key
Value values, i.e., specific parameter entity class object, such as Order classes below and Sku classes all contain correspondence in these classes
Attribute field, when rule calculates just needing the value of these attribute fields participates in calculating.
S12：Regular text is split, and is converted to word list.Chinese and English binding and category are carried out to vocabulary
Property binding, and by binding information storage in the database；And it after regular text is split, is converted according to binding information
To word list.Binding is to be preserved in the database, and system carries out data base querying on startup, is loaded into Installed System Memory
In, for Chinese rules text segmentation after Chinese language words, Chinese language words list to be converted in English word list process and is used,
Carry out the processes such as semantic analysis again later.Wherein, Chinese and English binding includes English word, phrase and symbol and Chinese is tied up
It is fixed, and Chinese is the machine language that user is often represented with language or mother tongue, English, therefore other common language and machine
The binding of language is included in the technical solution in the application.In Chinese vocabulary and english vocabulary binding, Chinese vocabulary and attribute
After binding, using Chinese redaction rule, then application system, that is, server-side dynamic analysis rule text, structure syntax tree, logic
The mode that execution etc. is combined, the Chinese so as to fulfill rule are write and are performed.As shown in Fig. 2, predefined system constant pool
Including vocabulary binding and attribute binding, these binding informations are stored into database.Logic rules define, the English of these definition
Vocabulary is all predefined in systems, which predefines and voluntarily predefine.Such as if, multi, system
The processing logic of if is defined, i.e., true/false judgement is carried out to expression formula below, system, which predefines to define to ask, multiplies letter
Number, multiplication calculating etc. is carried out to value below.Voluntarily predefine is that business personnel voluntarily predefines word progress logic.Data
Entity attribute binding is that some data entities that the system that is directed to is used carry out Chinese definition, if Order Instance is defined as order,
The order amount of money is defined as order.price, and order is order entity, and price is the attribute field of the order amount of money.Also, these
Entity can be added by the back-stage management page, be safeguarded.
S13：Semantic analysis is carried out to word list.Semantic analysis is carried out to word list to further include：Analyze word list,
Judge in word list with the presence or absence of the word for not carrying out semantic analysis；If being not present, terminate；If in the presence of, judge not into
Whether the word of row semantic analysis is the one kind predefined in vocabulary, pre-defined function, constant, parameter class and method；If so,
Corresponding predefined entity is appointed as, and is added in analysis word list；Otherwise throw exception.The analysis of words process be
Build the word meaning of a word analysis carried out before syntax tree, syntax tree be exactly after each word meaning of a word is analyzed and, it is basic again
On build.In embodiments of the present invention, specially：The first step, the word list after the fractionation of traversal rule text, judges
Whether the word that does not carry out semantic analysis is had, if it does not exist, then terminating；If it is present perform second step；Second step is sentenced
Whether the disconnected word is predefined vocabulary, such as：If, (, the vocabulary such as return to, if it is, being assigned therein as corresponding predetermined
Adopted entity；If it is not, then perform third step；Third walks, and judges whether the word is pre-defined function, such as：Seek multiplying letters of Denging
Number, if it is, being assigned therein as corresponding function entity；If it is not, then perform the 4th step；4th step judges the word
Whether it is constant, such as：300th, the constants such as 0.8, if it is, being assigned therein as corresponding constant entity；If it is not, then it holds
The 5th step of row；5th step judges whether the word is parameter class and method, such as：The parameters such as order price class, more than etc. side
Method, if it is, being assigned therein as corresponding object entity；If it is not, then perform the 6th step；6th step, does not all match
What is met is predefined, then throw exception.Predefined is the logic that a chain judges, can add and predefined sentence into chain
Disconnected logic, can extend at any time；The predefined entity that word confirms is added in meaning of a word analysis list by the 7th step.
S14：According to parameter object list builder syntax tree and performed.As shown in figure 4, after according to each analysis of words
As a result, structure syntax tree, which is exactly the layout of the execution sequence of code segment, performs each branch of syntax tree.
Syntax tree is code branch tree in fact, and each branch is a code number branch, and each branch is sequentially to perform
, each branch tree can perform according to the meaning of each keyword in the branch tree, such as the method tune of an object
With meeting goes to obtain corresponding parameter key, then go in Context by parameter key below according to the number of parameters of this method
Corresponding value is obtained, to trigger this method；Meanwhile the result that method returns can be also put into Context, so as to below
When code performs, the implementing result of front code can be got.Number in the result such as first row of the syntax tree, according to from
It is small to be performed to big data, if wherein illustrating that there are two branches at 1 time there are two 2, performing in sequence, branch below
The result of calculation of front branch may be used.Form is [word in syntax tree:Type declaration type definition], word is exactly generation
Code section in decomposite come word, type declaration is exactly to indicate the type of the word, type definition be exactly indicate the word as
Fruit is handled, and if class is object definition, constant is exactly that a variable stated or static constant, parameter are then needed from context
Obtained in Context etc..
Syntax tree branch be with '；' be split, syntax tree is built on the basis of the semanteme of word later, with " such as
Fruit (the order amount of money is more than 300), which then returns to ask, to be multiplied (the order amount of money, 0.8)；" for.After semanteme of word analysis, ' if ' analyzed
Go out for ' if ', just to below ' (the order amount of money is more than 300) ' expression formula carries out true and false judgement, i.e., ' the order amount of money ' is corresponding
' order.price ' and 300 progress ' being more than ' (>) compare, from Fig. 2-5, fourth line, it can be seen that '>' it is a binary ratio
Compared with one comparison function of correspondence, the function needs to obtain two parameter lists, i.e., two parameters before and after ' being more than ' carry out
Function relatively after, true-false value can be returned.If it is true, (return) logical consequence below is returned to, i.e., ' asks and multiplies (order gold
Volume, 0.8) it is ' multi ' corresponding function that ', ' ask and multiply ' is corresponding, and function needs can be that binary is multiplied or more
Member is multiplied, will behind parameter list asked multiplied successively, finally return that as a result, i.e. branch's execution terminates.In Fig. 2-5
CHILD_EXPRESS be branch's expression formula label, i.e. a code branch；METHOD_CALL is a parameter object
Function call label；ID is a parameter object label；CONST_STRING, CONST_INTEGER are a constant label,
Text i.e. in rule is constant or for the constant in parameter object.FUNCTION_CALL is a function call label
Deng.
