Under using the framework style based on RESTful+JSON, because a large amount of programs write in the past are all based on web
Service+XML mode.In order to avoid Technical Architecture change to cause a large amount of modifications of application program, it is necessary to which foreground is adjusted as far as possible
JSON forms are converted into the incoming XML of service form, JSON forms reconvert will be returned and return XML format, therefore, this is just related to
And to the mutual conversion between XML format and JSON forms.Final purpose is exactly transparent to application program, reduces project wind
Danger.
The analysis changed between XML format and JSON forms and implementation process：
1. the XML format and standard JSON forms of the company of analysis
The XML format node attribute of agreement has 4 types, is int, long, string, double respectively, specific case
Under such as：
<BATCH_TYPE type=" int ">1</BATCH_TYPE>
<TEMPLATE_ID type=" long ">1</TEMPLATE_ID>
<AUTO_CONFIRM type=" string ">N</AUTO_CONFIRM>
<SALE_PRICE type=" double ">100</SALE_PRICE>
In the JSON forms of standard character string must be caused with double quotation marks come, remaining need not, such as character string " a ".
Based on above premise, addition double quotation marks is needed to be converted into JSON type=in XML format " string " data
Form, namely need individually parsing XML file, for nodal community be type=" string " data addition double quotation marks turn
Change JSON form into.Other kinds of data can directly use the raw value in XML.Conversely, turn from JSON forms
Gaining XML format also has above-mentioned requirement.
2. XML format is converted into JSON forms
First, analysis default XML format is converted into JSON forms are what a kind of situations, specific data format fragment citing
It is as follows：
XML format data：<POOL_ID type=" string ">11</POOL_ID>
JSON data after conversion：
And the result that actually we want is " POOL_ID ":"11".Therefore, it is necessary to which XML format first is carried out into one
The process of " pretreatment ", i.e., the attribute of XML data format is removed, become<POOL_ID>11</POOL_ID>Form.
Secondly, for the ease of controlling transfer process, org.json storehouses is have selected as conversion API, be implemented as follows：
XML xml=new XML ()；
JSONObjectjso=xml.toJSONObject (xmlstr)；
String jsonstr=jso.toString ()；
1) org.json storehouses are increased income, it is possible to achieve the conversion of java objects and json objects, referring to:http://
www.json.org/java/index.html.The conversion between json and xml can also be realized.
2) above code API is that org.json storehouses provide.
3.JSON forms are converted into XML format
It is implemented as follows：
JSONObjectjo=new JSONObject (result)；
XML xml=new XML ()；
String xmlstr=xml.toString (jo)；
Above code library is all that org.json storehouses provide.
The implementation steps of the present invention are as follows：
1. environmental preparation
The jar bags that xml and json is changed introduce engineering project
2. xml forms are converted into json forms
String jsonStr=Xml2JsonForSitech.xmlToJson (xmlStr)
3. json forms are converted into xml forms
JSONObjectjo=new JSONObject (jsonStr)；
XML xml=new XML ()；
String xmlstr=xml.toString (jo).
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
