Through the above technical solutions, the product feature of product and product data can be stored as to the mode of key-value pair, it is
These key-value pairs are assigned in each classification bucket, in this way, need to only utilize Kazakhstan when user wants to look up the product data of corresponding product
Uncommon algorithm finds corresponding key-value pair from classification bucket, and then the corresponding product data of key-value pair is passed through corresponding to the key-value pair
Output interface output, and show user.When effectively preventing product data output, there are multiple product data and share one
Output interface, the case where causing output interface to block, and then accelerate the search speed of product data.
The data search method based on key-value pair of the present embodiment, further includes:
Step (1) collects at least one corresponding product feature of each name of product and the corresponding product of product feature
Data.
Product feature is converted into corresponding key assignments by step (2), and key assignments is formed key-value pair with corresponding product data,
And corresponding output interface is matched for key-value pair.
In this step, the product feature of various products and corresponding product data are collected, for subsequent use
Family is searched, and product feature is matched into the form of key-value pair with product data.And for the ease of the defeated of the product data
Out, corresponding output interface is matched for each key-value pair.
For example, being directed to product rotary drum washing machine, corresponding product feature has: washing weight, the date of manufacture, product colour,
Operating power etc., corresponding product data are as follows: 7.5kg, December 1, silvery white, 500w/h in 2017.Then, it does washing for impeller
The product feature of machine matches corresponding key assignments, washing weight: 001, the date of manufacture: and 002, product colour: 003, operating power:
004.The then key-value pair of product feature and product data composition are as follows: 001-7.5kg, 002-2017 December 1,003- are silvery white
Color, 004-500w/h.Finally, matching corresponding output interface for key-value pair, the output interface of 001-7.5kg is No. 1 delivery outlet,
002-2017 December 1 is No. 2 delivery outlets, and 003- silvery white is No. 3 delivery outlets, and 004-500w/h is No. 4 delivery outlets.

And put) stable performance is provided.
Step (5), in the database by the storage of classification bucket.
In this step, it will be stored with the classification bucket of multiple key-value pairs and corresponding output interface, existed according to the difference of classification
It is stored in database, to search corresponding classification bucket from database according to classification.
Through the above technical solutions, the product feature of each product and corresponding product data can be converted into accordingly
Key-value pair matches corresponding output interface for each key-value pair, when can prevent multiple product data while export, occupies same
A output interface, and appearance the case where cause output interface to block.It recycles hash algorithm that these key-value pairs are carried out classification to draw
It is stored in the classification bucket of corresponding classification after point, it thus can be according to the corresponding key assignments of product feature of certain product, from classification
Corresponding key-value pair, and then the product feature of certain product of calling and obtaining user needs are searched in bucket, so that entire search procedure is convenient
Quickly.
If in step 103, not searching key assignments to be found key-value pair to be found accordingly from classification bucket to be found, it was demonstrated that
The corresponding product data of one or more product features of the product to be found are not stored in database.
It then needs to be updated the classification bucket stored in database, therefore, the data based on key-value pair of the present embodiment
Lookup method, further includes:
Step A passes through internet search all-network product feature corresponding with name of product to be found.
In this step, it is first determined have all websites of the name of product to be found, and extract station address, to website
It accesses, all product features relevant to the name of product to be found in each website is all concentrated in together, then
Identical product feature is only retained into remaining deletion, remaining product feature is summarized as networking products spy
Sign.
Step B, by all-network product feature, networking products feature identical with product feature to be found is deleted, and is remained
Remaining networking products feature is missing product feature.
In this step, have in the all-network product feature to gather it is some identical as product feature to be found,
Have it is some different from product feature to be found, therefore in order to avoid these networking products features identical with product feature to be found
Interference, need to be deleted.Remaining networking products feature is only the missing product feature supplemented.
Step C searches the corresponding missing product data of missing product feature from network.
In this step, the corresponding station address of missing product feature is obtained, and is accessed to these websites, according to scarce
It loses product feature and obtains corresponding missing product data.And missing product data are downloaded and are saved in cache database.
Missing product data are passed through missing output for the corresponding missing output interface of missing product data matching by step D
Interface output.
In this step, from having found the corresponding missing product number of name of product to be found not having in database in network
According to rear, directly for these corresponding missing output interfaces of missing product data matching, (wherein, different missing product data are corresponding
Different missing output interface).Then it is combined with the target product data found in above-mentioned steps, and by respective
Output interface output.
Through the above technical solutions, the product data of the product needed in the classification bucket of database to user are searched
In the process, if corresponding product data can not be found in the classification bucket of database, or a part of corresponding product number is only found
According to the target for then needing to be searched in a network according to the name of product, and missing product data being corresponded to found
Product data are exported by corresponding output interface together, show user.It can guarantee the product number shown for user in this way
According to integrality.
Step E is converted into missing product feature to lack key assignments accordingly, by missing key assignments and corresponding missing product number
Key-value pair is lacked according to composition, missing key-value pair is subjected to mapping matching with corresponding missing output interface.
Step F is that missing key-value pair determines corresponding classification, and will lack key-value pair in the way of Hash mapping, with
And corresponding missing output interface is placed in corresponding classification bucket, and corresponding classification bucket is updated.
Step G, in the database by the storage of updated classification bucket.
In the above-mentioned technical solutions, when finding that the corresponding product data of corresponding name of product to be found can not be in database
After all being found in the classification bucket of storage, the corresponding missing product data of the name of product to be found that need to find from network
It adds in corresponding classification bucket, and then guarantees that the later period again searches the corresponding product data of the name of product to be found
When, it can all be found in the classification bucket of the database, no longer need to obtain from network, when saving the lookup of product data
Between.
Before step (5), the method for the present embodiment further include:
Step (5 ') is patterned each classification bucket in the way of iteration collection view by key-value pair,
Obtain lookup figure corresponding with each classification bucket.
It then corresponds to step 103 to specifically include: transferring the lookup figure in classification bucket to be found, according to key assignments to be found from looking into
It looks in figure and obtains corresponding key-value pair to be found.
In the above-mentioned technical solutions, by hash algorithm iteration collection view in the way of, by each classification bucket
In key-value pair be patterned, then by the key-value pair in each classification bucket with grid, stack, circle etc. search figure store,
Thus the product data that user needs directly can be searched according to figure of searching corresponding in classification bucket, wherein collection
View can dynamically change the layout for searching figure, or be laid out with any arrangement that you are envisioned that figure is searched.
It is deposited through the above technical solutions, the key-value pair in each classification bucket is searched figure with grid, stack, circle etc.
Storage, can accelerate the lookup time of product data.
Step (1) specifically includes:
Step (11), transfers the network address of at least one corresponding website of each name of product.
Step (12) accesses to website by network address, and obtains product corresponding with each name of product in website
Feature, and product data corresponding with product feature.
And/or
Step (11 '), after the setting command for receiving each name of product, by the corresponding setting window of each name of product
It is shown, so that user inputs product feature corresponding with name of product and product data in corresponding setting window.
Step (12 ') receives at least one product feature corresponding with each name of product and production that setting window transmits
Product data.
Through the above technical solutions, multiple product features of each product and corresponding can be obtained by two ways
Product data are obtained automatically by Web search respectively, if network obtains incomplete automatically, user can be by setting
It sets window and is manually entered corresponding product data.And then guarantee the integrality of the product data for each product collected.
Furthermore it is also possible to which periodically (for example, a week) to classification bucket storing data each in database, is updated, more
New mode can be any of the above-described one or two.
Step (5) specifically includes:
Step (51) is that each classification bucket is encrypted using setting code, wherein the setting code of each classification bucket is
Identical or different number.
For example, be arranged to 263* for the password of I classification bucket, the password of II classification bucket is arranged to 264* etc., or by this
The password of a little classification buckets is uniformly arranged to 2596.
It can guarantee the safety of each classification bucket store data inside in this way, and the password of each classification bucket can be regular
Adjustment, after cryptocompromise, someone steals data in classification bucket.
Step (52) matches corresponding symbol code for each encrypted classification bucket, wherein symbol code adds with each
The classification of classification bucket after close is corresponding.
In this step, the corresponding password of each classification bucket can be preferably distinguished, the password of each classification bucket is avoided to go out
The case where now obscuring.
Then corresponding step 103 specifically includes:
The classification that key assignments to be found is determined using hash algorithm obtains the corresponding symbol code of classification of key assignments to be found,
Corresponding classification bucket to be found is searched from database according to corresponding symbol code, and using setting code to classification to be found
Bucket is decrypted.
By the process for encrypting and decrypting above, the safety of the data stored in each classification bucket can effectively ensure that,
Data are avoided to be stolen.
Technical solution through this embodiment, the product feature of product and product data can be stored as key-value pair
Mode is assigned in each classification bucket for these key-value pairs, in this way, when user wants to look up the product data of corresponding product, only
Corresponding key-value pair need to be found from classification bucket using hash algorithm, so by the corresponding product data of key-value pair by with the key
Value exports corresponding output interface, and shows user.When effectively preventing product data output, there are multiple product data
The case where sharing an output interface, output interface caused to block, and then accelerate the search speed of product data.
Include the following steps: in the data search method based on key-value pair of another embodiment of the application
One, data management
1, data update, and data (that is, product feature and product data of product) acquisition modes are broadly divided into network interface
Two ways is obtained and be manually entered, data real-time update and data scalability, two kinds of acquisition data mode data are realized
Source is different, and network interface obtains mainly adds data by administrator in back-stage management, and APP is getting data needs
Back office interface can be requested when update, complete the update to local data；It is manually entered mainly by developer to data management
The addition interface of system calls, the update of complete paired data.In order to guarantee the safety of data, need for the data got
Carry out data encryption.
2, data are stored
After the completion of data update, each product feature and corresponding product data are corresponding, and data can be in terms of storing
The corresponding product data of product feature are simply interpreted as key-value pair one by one, according to different data types by data with key
The form of value pair stores in the database, as shown in Fig. 2, key-value paies, i.e. key-value pair, key indicate key in figure
(that is, product feature), value indicate key assignments (that is, product data).Corresponding output interface is matched for each value.
Two, data search is laid out
Fast data search matching is a main modular based on key-value pair quick search, is mainly answered in key-value pair inquiry
With Hashmap, the realization of the Map interface based on Hash table.For business demand, HashMap is as unordered storage side
In case, data search speed is fast.
Specific search procedure is as follows:
It (1) is that each key-value pair matches corresponding mapping relations, and allows using null value and null by Hashmap
Key.This mode does not guarantee the sequence of the mapping relations of each key-value pair, less guarantees the sequence constancy.
Then, category division is carried out using the mapping relations that hash function is these key-value pairs, it is corresponding assigns to each classification
Classification bucket in, can for basic operation (get and put) provide stable performance.
(2) according to the mapping relations of the key-value pair in each classification bucket obtained above and classification bucket, iteration is utilized
The mode of collection view is patterned, and is obtained grid, stack, circle etc. and is searched figure, collection view can move
State changes the layout for searching figure, or the lookup figure formed with arrangement mode set by user is laid out.
Wherein, the quantity and classification bucket that iteration collection view is patterned required time and classification bucket can deposit
The mapping relations quantity of the largest key value pair of storage is proportional.
(3) corresponding value product data are searched using hash algorithm, detailed process is as shown in Figure 3.
The first step obtains hashcode according to key key using hash algorithm in the lookup figure in corresponding classification bucket.
Method: int hash=hash (key.hashCode ()).
Second step obtains the corresponding position in searching figure value according to hashcode, phase is extracted from corresponding position
The value answered.Method: int i=indexFor (hash, table.length).
If not finding the corresponding hashcode of key key in the graphic, it was demonstrated that corresponding value product data information lacks
It loses, needs quickly to be searched corresponding value product data by following manner:
Firstly, it is necessary to which the title of corresponding product is obtained by network according to key key.
Then, the corresponding all value product data of the name of product, and the value that will acquire are obtained from network
Product data value product data corresponding with the name of product in database are compared, and finding does not have in database
One or more value, i.e. missing product data.
Thus a key can be converted into a fixed position, the reason of this is also that by quick lookup.
When user needs to obtain corresponding product data, so that it may obtain the position where the corresponding value of the key key, quickly
Take out value.
Wherein, hashmap bottom is realized with data, specific procedure code are as follows:
transient Entry[]table；Here table is exactly for storing data.
static class Entry<K,V>implements Map.Entry<K,V>{
final Kkey；
V value；
Entry<K,V>next；
final inthash；}
Wherein, Entry indicates variable.
Three, data export
The correspondence output interface for obtaining the value found returns to caller by corresponding output interface, and is opened up
Show.
Above-mentioned corresponding flow chart is summarized as shown in figure 4, steps are as follows:
Step 401, network obtains product data, is directly entered step 403.
Step 402, product data are manually entered, enter step 403.
Step 403, product data are encrypted.
Step 404, product data are stored.
Step 405, product data are searched.
Step 406, judge whether to find corresponding product data, be to enter step 407, otherwise enter step 408.
Step 407, product data are decrypted and is exported.
Step 408, network obtains name of product.
Step 409, the product data of missing are searched.
Step 410, the product data of missing are encrypted, subsequently into step 407.
Step 411, product data are shown.
In conclusion need to only utilize hash algorithm from classification bucket when user wants to look up the product data of corresponding product
In find corresponding key-value pair, and then it is the corresponding product data of key-value pair are defeated by output interface corresponding with the key-value pair
Out, the purpose for quickly searching product data is realized.In addition, can also effectively the product data of missing quickly be searched and be opened up
Show.
