Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
Embodiment 1
As shown in figure 1, a kind of light weight method that distributed sequence number is generated based on JAVA chained lists, is comprised the following steps：
S1, parameter is generated with default generating mode generation setting quantity according to the sequence number in default configuration file
Sequence number, and the sequence number of the setting quantity of generation is stored in the global variable chained list of the JAVA of distributed deployment applications；
S2, the position of last sequence number in the sequence number of the setting quantity of generation recorded relative in configuration file
In the sequence number generation parameter answered；
S3, is carried out with synchronization mechanism according to the quantity of the sequence number of required acquisition to the sequence number in global variable chained list
Shearing, obtains the sequence number of requirement.
The present invention is by the global currently available sequence numbers of storage of linked list of JAVA, in JAVA application software to distributed deployment
When, independent of other software and application, it is that the generation of unique sequence numbers under distributed deployment can be achieved by easy configuration, only needs
Take the hardware and underlying resource of lightweight.The position of formation sequence number is recorded after formation sequence number, it is ensured that sequence number
The continuity of generation and repetition is prevented effectively from, and realizes that sequence number provides uniqueness by JAVA synchronization mechanism.
Further, the sequence number generation parameter in configuration file includes：It is initial using coding, default queue length, sequence
Value and current sequence maximum；Current sequence maximum is used for last in the sequence number for the setting quantity that record has been generated
In the position of sequence number, S1 first generation setting quantity sequence number when, by current sequence maximum be initialized as with the beginning of sequence
The equal value of initial value.
Specifically, the parameter included in configuration file has：Using coding, default queue length, sequence initial value and current
Sequence maximum.First during formation sequence, current sequence maximum is initialized as to the value equal with sequence initial value, that is, worked as
The position of last sequence number is the value equal with sequence initial value in the preceding sequence number generated.Such as sequence initial value can
To be set to 100000000, then first formation sequence when, the position of last sequence number is in the sequence number currently generated
100000000, subsequently generate sequence number on the basis of this position.

Default queue length, sequence initial value and current sequence maximum.For example, being 001 using encoding setting, sequence number initial value is
100000000, default queue length is 200000.Then according to default generating mode, for example, coding+(current sequence is applied
Maximum+1) mode assemble formation sequence number 001100000001, sequentially generate 200000 sequence numbers, storage to JAVA should
In global variable chained list；And recorded the position of last sequence number in the sequence number of generation relative in configuration file
In the sequence number generation parameter answered, i.e., current sequence maximum is changed to 100200000.
, can be according to not incrementally again with application coded combination into sequence number after formation sequence value in the improvement
Same scene needs to generate various types of sequence numbers, adapts to multiple use；The sequence number of generation is continuously regular, with unique
Property, it is prevented effectively from repetition.
Further, first judge whether the length of global variable chained list meets before the shearing with synchronization mechanism is carried out in S3
Length needed for this shearing, if so, the shearing of mechanism is then synchronized, if it is not, then performing S1.
Specifically, before the shearing of mechanism is synchronized, first judging that global variable chained list length is less than required length (such as
100), if less than required length, S1 being introduced into before shearing and is increased newly in a collection of sequence number deposit global variable chained list, then
The sequence number of requirement is sheared again.
In the improvement, the length of global variable chained list is first judged before shearing sequence number, can be prevented in real process
The problem of needing the sequence number that is produced during long-term a large amount of shearing sequence number not enough, so that an automatic rounded system is formed,
Can continuous continual offer sequence number.
Further, as shown in figure 1, this method also includes：S4, carries out what is got after the shearing with synchronization mechanism in S3
Default prefix is added before sequence number, combination obtains required sequence number.
Specifically, prefix can will be added to meet the demand under different application scene before the sequence number of acquisition, such as
YYYYMMDD+ sequence numbers.
In the improvement, the bigger type for enriching sequence number, it is adaptable to more different application scenarios.

The mode of coding+(current sequence maximum+1) assembles formation sequence number 001100000001, sequentially generates 200000 sequences
Number, store in the global variable chained list applied to JAVA；And sequence number logging modle is by last sequence in the sequence number of generation
The position of row number recorded in sequence number generation parameter corresponding in configuration file, i.e., be changed to current sequence maximum
100200000。
, can be according to not incrementally again with application coded combination into sequence number after formation sequence value in the improvement
Same scene needs to generate various types of sequence numbers, adapts to multiple use；The sequence number of generation is continuously regular, with unique
Property, it is prevented effectively from repetition.
Further, sequence number acquisition module is additionally operable to before the shearing with synchronization mechanism is carried out, and first judges global variable chain
Whether the length of table meets the length needed for this shearing, if so, the shearing of mechanism is then synchronized, if it is not, then calling sequence
The sequence number of number generation module generation setting quantity.
Specifically, before the shearing of mechanism is synchronized, first judging that global variable chained list length is less than required length (such as
100), if less than required length, first calling sequence generation module increases a collection of sequence number deposit overall situation newly and become before shearing
Measure in chained list, the sequence number of requirement is then sheared again.
In the improvement, the length of global variable chained list is first judged before shearing sequence number, can be prevented in real process
The problem of needing the sequence number that is produced during long-term a large amount of shearing sequence number not enough, so that an automatic rounded system is formed,
Can continuous continual offer sequence number.
