Description
Technical Field
The invention belongs to the technical field of computer software, relates to an ID generation system, and particularly relates to a configurable ID generation system and method based on expressions.
Background
In modern software systems, unique numbers, business serial numbers or primary keys are the most common design elements. Such as a user number, order number, request for running water. These numbers generally require one or more of the following characteristics: (1) the global is unique; (2) (7) the length is moderate, and the service requirement can be met; (8) the generation efficiency required under the high concurrency scene is met.
In terms of solving distributed IDs, many enterprises or individuals propose good solutions, typically uuid, guid, database self-increment sequence, snowflow algorithm, and the like. These solutions address one or more of the 4 basic features. For example, uuid has the above-mentioned characteristics 1 and 4, but cannot satisfy the above-mentioned characteristics 2, 3, 5, etc., and thus cannot be used for the database primary key; guid satisfies the characteristics 1, 2, 4 and 5, but the length is 128bit, which is not satisfied, and the storage consumption is too large; the database self-increment sequence meets the characteristics 1, 3 and 7, but does not meet the requirements 4, 5, 6 and 8, and is generally used in scenes with small non-sensitive data volume. The snowfly meets the requirements of 1, 2, 4, 5 and 8, is a very excellent ID generation algorithm and is also the algorithm which is most used in the internet industry at present, but the sequence length of the snowfly is generally greater than 19 bits, the snowfly is overlong in most occasions, and in addition, the service date attribute of the snowfly is not obvious and can be deduced through complex bit operation.
To summarize, the prior art provides solutions from a unique perspective, with fewer solutions in customization.
In actual production, enterprises generally use various ID generation algorithms comprehensively, and on the basis of the original algorithm, some generation modes are subjected to secondary transformation through modes of character string splicing, filling and the like, and finally, a numbering rule meeting requirements is generated. This transformation process is typically done by hard coding and cannot be flexibly customized to some specific scenarios. Hard coding can also easily damage historical rules, causing errors in the generating system.
In view of the above, there is a need to design a new ID generation method to overcome at least some of the above-mentioned disadvantages of the existing ID generation methods.

Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
For a further understanding of the invention, reference will now be made to the preferred embodiments of the invention by way of example, and it is to be understood that the description is intended to further illustrate features and advantages of the invention, and not to limit the scope of the claims.
The description in this section is for several exemplary embodiments only, and the present invention is not limited only to the scope of the embodiments described. It is within the scope of the present disclosure and protection that the same or similar prior art means and some features of the embodiments may be interchanged.
The term "connected" in the specification includes both direct connection and indirect connection.
The invention discloses a configurable ID generation system based on an expression, and FIG. 1 is a schematic diagram of the configurable ID generation system in an embodiment of the invention; referring to fig. 1, the system includes: an ID expression setting module 1, an ID expression analysis module 2 and an ID generation module 3.
The ID expression setting module 1 is used for setting an ID expression, and the ID expression includes at least one node, and the nodes are combined to form the ID expression (a combination mode or a decorator mode can be used in implementation). The ID expression parsing module 2 is configured to parse the ID expression set by the ID expression setting module, and parse each node included in the ID expression from the ID expression (in implementation, an interpreter mode may be used to parse the expression to generate a combined ID generator). The ID generation module 3 is configured to generate a corresponding ID by using an analysis result of the ID expression analysis module according to each node of the ID expression analyzed by the ID expression analysis module.
The invention is different from other ID solutions in that a unique sequence is generated, and the key service significance is not considered to be contained in the ID. The invention mainly solves the problem that various service meanings are included in the expression according to requirements, and the sequence length is cut according to the requirements, thereby ensuring that the total length of the ID is maintained in a set length range.
Meanwhile, the method of the invention is different from the hard coding method, the ID needs to be customized and developed in different programming languages, and business personnel have no ability to customize and adjust the ID. The invention uses a simple character string expression mode, hides the coding details, realizes the quick customization of the ID, and can customize the ID according to the requirement even for operators without programming experience.
In an embodiment of the present invention, the ID generation module 3 introduces a sequence generation interface in the sequence converter, and the client uses a customized sequence generator through the sequence generation interface. In an embodiment, the ID generation module 3 uses a precompilation mode to initialize each sequence converter in advance, and assigns and compiles the relevant parameters, so that it is not necessary to initialize the object each time the generation is performed.
The invention further discloses a configurable ID generation method based on expression, and FIG. 2 is a flow chart of the configurable ID generation method in an embodiment of the invention; referring to fig. 2, the method includes:
step S1, setting an ID expression, wherein the ID expression comprises at least one node, and all the nodes are combined to form the ID expression;
step S2, parsing the set ID expression, and parsing out each node included in the ID expression from the ID expression;
step S3, the corresponding ID is generated from each node of the ID expression analyzed by the ID expression analysis step using the analysis result of the ID expression analysis step.
In an embodiment of the present invention, in step S3, a sequence generation interface is introduced into the sequence converter, and the client uses a customized sequence generator through the sequence generation interface. In an embodiment, a precompilation mode is adopted to initialize each sequence converter in advance, and the relevant parameters are assigned and compiled, so that the object does not need to be initialized every time the object is generated.
In an embodiment of the present invention, a configurable ID generation method includes:
step S1, an ID expression design step.
The ID typically has one or more of the following elements: fixed identifiers, variable identifiers, dates (different formats are used on different occasions), relative date values (difference values with respect to a reference date), random numbers, sequences (increasing trend, and will not repeat under certain conditions; for example, when conditions other than sequences are consistent, sequences will not repeat), and lengths of segments. A typical flow diagram is shown in figure 3.
The segment identifiers are described using special keywords, such as: d or date represents a date field, seq represents a traffic flow, r represents a random number, offset day represents an offset date, ph represents a dynamic variable, these keys are identified with a% number, and the value following the% number identifies the field length of this field. And the identifier is not represented by a fixed identifier and is output as it is. The above business numbering rule may be described as A% 2 ph% 8 date% 10 seq.
In an embodiment of the invention, further enhancement and optimization are carried out on the basis of the following steps: (1) the length that the input party can guarantee can not be disposed, for example the service identifier itself is also 2 bits, the default is 8 bits after the date is formatted, then these two do not need to dispose again, simplify to: a% ph% date% 10 seq; (2) sequence we expect to use a specific service sequence, avoiding global mix-ups, the date requirement can be configured in other formats, where corresponding parameters can be added, such as: a% ph% date { yyMMdd }% 10seq { BIZ _ TAG }.
Based on the idea, the invention can freely expand the keywords and add more elements which are expected to be used, such as complex expression operation, special character filling and the like.
Step S2, an ID expression parsing step.
The ID expression is processed by a Parser to be responsible for conversion, and the conversion process is shown in FIG. 4.
The final nodes comprise simple nodes and combined nodes, and the analyzed nodes form a chain relation. As shown in fig. 5, the node types are freely combined.
Step S3, an ID generation implementation step of the ID expression.
When generating the ID, the nodes are actually output character strings conforming to the node rule and spliced together. For example: the data output by the date node is implemented as follows: i.e. the current date is formatted and output.
The focus here is on the implementation of the sequence segments. The sequence is the core of an ID and is an essential part. Therefore, the scheme does not create a sequence generation scheme additionally, but introduces a sequence generation interface in the sequence converter, and the client can use a self-defined sequence generator by implementing the interface, so that the modification of the existing system is reduced with the minimum cost.
In order to improve the efficiency of sequence generation, the scheme also adopts a precompilation mode to initialize each converter in advance, and assigns and compiles related parameters, so that an object does not need to be initialized every time of generation.
The Converter is an abstraction of the Converter, and a customer can customize the Converter to meet the composition requirements of more elements and customize a more personalized ID scheme.
The invention realizes the customized output of different ID elements through different converters by innovatively abstracting various common elements in the ID. And then, the combination processing of each element is completed through a simple and easy-to-use regular expression, and finally a format requirement meeting the ID under different scenes is generated, so that the ID customization workload is greatly simplified, and the development time is saved. Meanwhile, the format expression perspectives the sequence rule to a user, so that the user can understand and use the sequence rule more conveniently.
The invention creatively completes the customization of a complex ID through a simple expression without any additional coding on a using end, which is not available in the prior art. By using the scheme, the efficiency of ID customization realization can be improved by hundreds of times.
The following are currently several typical ID customization schemes comparisons:
TABLE 1 several exemplary ID customization scenarios comparison tables
The table shows that the invention can meet various coding customization requirements with little cost, and has the characteristics of customizable length, high degree of freedom and small development workload.
In summary, the system and the method for generating configurable IDs based on expressions provided by the present invention can fulfill the customization requirements of various IDs through simple mode configuration, and do not need hard coding, thereby reducing the coding workload and the error probability.
