Description
Technical field
This application involves data processing fields, in particular to a kind of parameter verification method and device.
Background technique
As the data explosion formula in industry increases, traditional relevant database has been unable to satisfy industry to more than one hundred million easily
Big data table storage and quick-searching requirement, be badly in need of a kind of new database in industry and be used to store what these explosions increased
Data.HBase comes into being in this context.HBase is building in HDFS (Hadoop Distributed File
System, Hadoop distributed file system) on NoSQL (not only SQL, non-relational data) database, pass through
High reliability, high-performance, column storage, the scalable and real-time ability for reading and writing database are provided, becomes big watch in industry and stores, is fast
Widely used database solution under speed retrieval scene, and achieve good effect.
HBase as the distributed non-relational database operated on HDFS, possess the data storage capacities of magnanimity with
And the data retrieval advantage of high speed, it is widely used in the real-time analysis of mass data, quick-searching application scenarios.However it is primary
HBas do not support directly Chinese to be used to build table, if can be directly dished out corresponding error message when creation table using Chinese.Mesh
Before, the common way of industry is that Chinese is converted to Unicode coding by program, using Unicode coding as table name
Create tables of data.But the Chinese of Unicode coding form, user is readability very poor, and needing to consult corresponding encoded table can just obtain
Obtain its corresponding Chinese character.Therefore, for using the user of Chinese, user experience is extremely bad.

Fig. 1 is please referred to, is the hardware structural diagram that the application is the data processing equipment 100 that embodiment provides, the number
It include processor 130, memory block and parameter calibrator 110 according to processing equipment 100, the memory 120 and processor
130 each elements are directly or indirectly electrically connected between each other, to realize the transmission or interaction of data.For example, these element phases
It can be realized and be electrically connected by one or more communication bus or signal wire between mutually.The parameter calibrator 110 includes extremely
Few one can be stored in the memory 120 or be solidificated in the data processing in the form of software or firmware (firmware)
Software function module in the operating system (operating system, OS) of equipment 100.The processor 130 is for executing
The executable module stored in the memory 120, for example, software function module included by the parameter calibrator 110 and
Computer program etc..
Wherein, the memory 120 may be, but not limited to, random access memory (Random Access
Memory, RAM), read-only memory (Read Only Memory, ROM), programmable read only memory (Programmable
Read-Only Memory, PROM), erasable read-only memory (Erasable Programmable Read-Only
Memory, EPROM), electricallyerasable ROM (EEROM) (Electric Erasable Programmable Read-Only
Memory, EEPROM) etc..Wherein, memory 120 is for storing program, the processor 130 after receiving and executing instruction,
Execute described program.
The processor 130 may be a kind of IC chip, the processing capacity with signal.Above-mentioned processor can
To be general processor, including central processing unit (Central Processing Unit, abbreviation CPU), network processing unit
(Network Processor, abbreviation NP) etc.；Can also be digital signal processor (DSP), specific integrated circuit (ASIC),
Field programmable gate array (FPGA) either other programmable logic device, discrete gate or transistor logic, discrete hard
Part component.It may be implemented or execute disclosed each method, step and the logic diagram in the embodiment of the present application.General processor
It can be microprocessor or the processor be also possible to any conventional processor etc..
Referring to figure 2., Fig. 2 is the step flow chart of parameter verification method, which is applied to shown in FIG. 1
Data processing equipment 100, the data processing equipment 100 may be, but not limited to, smart phone, PC (personal
Computer, PC), tablet computer, personal digital assistant (personal digital assistant, PDA), mobile Internet access set
Standby (mobile Internet device, MID) etc..Each step of this method is described in detail below.
Step S100, obtains the operating parameter in the Hbase database operating instruction, and the operating parameter is byte class
The array of type.
Optionally, which obtains the operational order to the Hbase database, and according to the Hbase number
According to the syntax rule of library operational order, which is parsed, obtains operating parameter therein.
For example, in a kind of possible example, the operational order be " create'student_info', '
contacts','address'".The function of the operational order is to establish one in Hbase database to be " student_
The table of info ", the table include two column families, respectively " contacts " and " address "；" create " is the behaviour of operational order
Make function, is the keyword in Hbase database.In this way, the data processing equipment 100 is corresponding according to different operational orders
Syntax rule obtains operating parameter therein.
The operating parameter is converted to the array of char type by step S200.
The data are converted to integer by step S300, the data being successively read in the char type array, with described
Unicode coding range is compared.
Optionally, operating parameter acquired in the data processing equipment 100 is the array of byte type in Java.The byte
The data length of each data is 8bit in the array of type, and the Unicode of Chinese character is encoded to 16bit length.For
The coding of each of operating parameter character is judged, needs for the byte type array of the 8bit to be converted into
The char type array of 16bit.
For example, in a kind of possible example, one table of creation in Hbase database, entitled " student information _
Name ", with the storage of array of byte type, array is entitled " qualifierName ".The data processing equipment 100 is got
After the table name, the array of the byte type is converted to the array of char type by following code:
Char arr=new String (qualifierName) .toCharArray ()；
Wherein, " qualifierName " is used as parameter, creates anonymity String object, calls the object
String object, is converted into the array of char type by " toCharArray () " method.The data processing equipment 100 successively will
Data conversion in char type array is compared at integer, and with the coding range of preset characters, wherein the preset characters
Type includes default English character, predetermined symbol character and Chinese character.For example, the data processing equipment 100 is by char class
" " of type is converted into integer, by the integer successively with the Unicode range of English character, the coding range of predetermined symbol character
And the coding range of Chinese character is compared.
Step S400, if the corresponding integer of the data is all located in the Unicode coding range, according to the behaviour
Make parameter and executes corresponding operation instruction.
After the data processing equipment 100 verifies operating parameter, if the character in the operating parameter belong to it is default
The legitimate characters of English character, predetermined symbol character and Chinese character then execute corresponding operation according to the operating parameter and refer to
It enables, the tables of data of corresponding Chinese is created in the Hbase database.If including forbidden character in the operational character,
Such as " < ", "? " or " % " etc., then the data processing equipment 100 is without the corresponding operational order of the operating parameter.
In this way, user directly can establish Chinese data table using Chinese in Hbase database, making for user is improved
With experience.
It is worth noting that parameter verification method provided by the embodiments of the present application, which passes through modification
Hbase data after source code carry out execution this method.
