Technique effect.
Technical solution of the present invention is described in detail below by accompanying drawing and specific embodiment, it should be understood that the application
Specific features in embodiment and embodiment are the detailed description to technical scheme, rather than to present techniques
The restriction of scheme, in the case where not conflicting, the technical characteristic in the embodiment of the present application and embodiment can be mutually combined.
The terms "and/or", only a kind of incidence relation for describing affiliated partner, represents there may be three kinds of passes
System, for example, A and/or B, can be represented:Individualism A, while there is A and B, these three situations of individualism B.In addition, herein
Middle character "/", it is a kind of relation of "or" to typically represent forward-backward correlation object.
Embodiment 1:
A kind of data processing method flow chart that Fig. 1 provides for the embodiment of the present application, methods described is applied to webpage
Data acquisition, specifically, a kind of data processing method that the embodiment of the present application is provided, including three phases:Preparatory stage, solution
Analyse content of pages stage, data persistence stage.
The preparatory stage includes step 101 to step 103:
Step 101:Obtain the first webpage;
Step 102:The object of first webpage is obtained according to first webpage;
Specifically, obtained after first webpage, first webpage is analyzed, according to right by step 101
The analysing content of first webpage, determines the object of first webpage, and the object can be specifically JavaBean,
JavaBean is a kind of special class in Java language, be able to can be carried out by multiple object encapsulations into an object (Bean)
There is provided without reference configuration device, there is provided getter methods and the attribute of setter way access objects for serializing.In JavaBean
" Bean " is the usual call of the software capable of being recombined component for Java.
Step 103:The between first webpage and the object is obtained according to the object and first webpage
One mapping relations;
Specifically, the info web of first webpage is encapsulated into the object, then completed first net
Page arrives the mapping of the object.Further, the object includes:Need crawl data, positioning explain, value explain and
Data normalization processing.First mapping relations include:The data that are captured the need for first webpage, positioning are explained, taken
Data, positioning note, the value captured the need for value note and data normalization processing and the object is explained and data mark
The mapping relations of standardization processing.By setting up the first mapping relations of first webpage and the object, page is subsequently completed
When face is parsed, with the technique effect for improving rate of code reuse.
Wherein, it is described note be also metadata, be a kind of other explanation of code level, can state bag, class, field, method,
Before local variable, method parameter etc., for being illustrated to these elements, annotation;The data normalization be enterprise or
The process being standardized to the definition of data, tissue, supervision and protection is organized, because different variables usually have different lists
Position and different degrees of variation, before data analysis, we are usually required data normalization first.
The parsing content of pages stage includes step 104 to step 107:
Step 104:The second webpage is obtained, wherein, first webpage and second webpage have identical attribute letter
Breath;
Specifically, it can be downloaded on network and obtain second webpage, second webpage is webpage to be resolved,
Wherein, first webpage and second webpage have identical attribute information, so that second webpage utilizes described the
First mapping relations of one webpage and the object carry out page parsing.
Step 105:Position of the element to be obtained in second webpage is obtained according to first mapping relations;
Specifically, the object also includes positioning note, and first mapping relations include determining for first webpage
Explain the mapping relations that the positioning with the object is explained in position.The note content that the positioning is explained is specifically, pass through positioning
Mode obtains the element being selected in DOM using JSoup.Wherein, the positioning can by element ID, element property or
Select selectors are realized;The JSoup is a kind of Java html parser, can directly parse some URL addresses, Html
Content of text, can take out and peration data by DOM, CSS and similar to jQuery operating method;The DOM's is complete
Referred to as DocumentObject Model, i.e. DOM Document Object Model, define the standard side for accessing and operating HTML/XML documents
Method, and corresponding document is rendered as the tree construction with element, attribute and text.
It is described to obtain position of the element to be obtained in second webpage according to first mapping relations, be specially:
The position for obtaining element to be obtained in second webpage is explained according to positioning, i.e., by element ID, element property or
Select selectors realize that the modes such as element are positioned, and position of the element to be obtained in second webpage is obtained using Jsoup
Put.
Step 106:Data of the element to be obtained in the position are obtained according to first mapping relations;
Specifically, the object also includes value note, and first mapping relations also include first webpage
Value explains the mapping relations explained with the value of the object.The note content that the value is explained is specifically, pass through positioning
Behind the position for obtaining the element to be obtained, the value of the element is obtained, can obtain described by Text, Html, Attr
Data of the element to be obtained in the position.It is described to obtain the element to be obtained in institute's rheme according to first mapping relations
The data put, be specially:The element to be obtained is obtained in the data of the position by calling value to explain, that is, is passed through
Text, Html, Attr obtain the element to be obtained in the data of the position, for json data structures, can be used directly
One special note@json carrys out value.Wherein, the json is a kind of data interchange format of lightweight.
Step 107:Judge the data type of the data;
Specifically, the element to be obtained is obtained after the data of the position by step 106, it is necessary to judge described
The data type of data.
Step 108:When the data type is basic data type, the data are standardized.
Specifically, when the data type is the array of basic data type either basic data type composition, institute
It is the data that can not directly use to state data, then the data is standardized, the data that can be used directly.Its
In, the basic data type includes:In java, each variable must state a type, java basic data types
Include Boolean type, integer, floating point type etc..
Further, the data persistence stage includes:By the data Cun Chudao databases after the standardization
In.
Specifically, the data after the standardization that above-mentioned steps are obtained are the data that can be used directly, can by described in
The data storage directly used is to database, or the position such as local disk, available for subsequently using, saves time and resource.
Further, methods described also includes:When the data type is not basic data type, then the 3rd net is obtained
Page, wherein, first webpage and the 3rd webpage have identical attribute information.
Specifically, by the judgement of step 107, when the data type is not basic data type, then need after
It is continuous to obtain the 3rd webpage, that is, continue to download webpage to be resolved, and repeat step 104 to step 107.
