如何從其他webelements存在的test.properties中讀取json數據

Question

我在test.properties文件中有一些WebElements，我需要讀取和存儲該文件中的所有json數據。任何人都可以請幫助閱讀從Java中的屬性文件中的所有json數據。

我試過所有閱讀和存儲數據的方式，但沒有運氣。

這是我在性能webElements文件：

mprHomePageLogo=//span[@class='si mpr-logo-h40px' and text()='MyPerfectResume.com'] 
mprHomePageLogoNewLP=//*[@class='inner-container']/span[@class='logo'] 
textLabel1=//*[@id='mt_mac_headline']/h1[text()='The Online Resume Builder So Easy to Use'] 
headingTextLabelOnNewLP=//*[contains(@class,'h1') and contains(text(),'Your Resume, Made')]/../h1/span[text()='Easy'] 
textLabel2=//*[text()='My Perfect Resume takes the hassle out of resume writing. Easy prompts help you create the perfect job-worthy resume effortlessly!'] 
desktoplikeImageOnLP=//object[contains(@class,'hero-desktop')]/following-sibling::a 
iconsAndArrows=//*[@id='page-header-ctnr']/ul/li[@id="icon1" and @class="icon-ctnr"]/following-sibling::li[@id="arrow1" and @class="arrow-ctnr"]/following-sibling::li[@id="icon2" and @class="icon-ctnr"]/following-sibling::li[@id="arrow2" and @class="arrow-ctnr"]/following-sibling::li[@id="icon3" and @class="icon-ctnr"] 
jsonArray= {"card":[{"Name":"1test1","place":"1placetest1"},{"Name":"2test2","place":"placetest2"},{"Name":"3test3","place":"3placetest3"}]} 
textLabel3532=//*[text()='My Perfect Resume takes the hassle out of resume writing. Easy prompts help you create the perfect job-worthy resume effortlessly!'] 
desktoplikeImageOtestnLP=//object[contains(@class,'hero-desktop')]/following-sibling::a 
jsonArray2= {"card":[{"Name":"test1","place":"placetest1"},{"Name":"test2","place":"placetest2"},{"Name":"test3","place":"placetest3"}]} 

正如你可以看到有這個屬性文件（jsonArray & jsonArray2）兩大JSON數據，我需要閱讀這一切鍵和值jsonArray。

Answer 1

首先，您需要讀取文件中的值。這可以用下面的代碼使用standart java包來完成

try { 
     Properties prop = new Properties(); 
     String propFileName = "test.properties"; 
     inputSecretStream = getClass().getClassLoader().getResourceAsStream(propFileName); 
     if (inputSecretStream != null) { 
      prop.load(inputSecretStream); 
     } else { 
      throw new FileNotFoundException("property file '" + propFileName + "' not found in the classpath"); 
     } 

     String jsonArray = prop.getProperty("jsonArray"); 
     String jsonArray2= prop.getProperty("jsonArray2"); 
    } catch (Exception e) { 
     System.out.println("Exception: " + e); 
    } finally { 
     inputSecretStream.close(); 
    } 

然後你應該解析你的JSON。我正在使用Google的圖書館Gson。它應該是這個樣子

 JsonArray jarray = new JsonParser().parse(jsonArray).getAsJsonArray(); 
     JsonObject jobject = jarray.getAsJsonObject("Name");

@Ravi : you need gjson lib to parse the json data as @Sympth explained in above solution. 
Please find the below solution , Here I am reading data as InputFile.properties data and parsing it and storing it in HashMap. 

import java.io.BufferedReader; 
import java.io.FileInputStream; 
import java.io.FileReader; 
import java.io.IOException; 
import java.util.HashMap; 
import java.util.Properties; 

import com.google.gson.JsonArray; 
import com.google.gson.JsonElement; 
import com.google.gson.JsonObject; 
import com.google.gson.JsonParser; 

public class JsonParserUtility { 

    public static void main(String[] args) { 
     try { 
      HashMap<String,String>jsonMap = new HashMap<String,String>(); 
      JsonParserUtility jsonParserUtility = new JsonParserUtility(); 
      String filePath = "$PLEASE PROVIDE properties file path here"; 
      //e.g. /Users/maheshjoshi/Desktop//InputFile.properties 
      Properties prop = new Properties(); 
      FileInputStream input = new FileInputStream(filePath); 
      // load a properties file 
      if (input != null) { 
       prop.load(input); 
      } 
      String jsonArray1 = prop.getProperty("jsonArray"); 
      String jsonArray2= prop.getProperty("jsonArray2"); 

      jsonMap.putAll(jsonParserUtility.parseJsonDataAndFetchAllValues(jsonArray1)); 
      jsonMap.putAll(jsonParserUtility.parseJsonDataAndFetchAllValues(jsonArray2)); 

      int count = 0; 
      for (String key : jsonMap.keySet()) { 
       count++; 
       System.out.println(count+". key : "+key+" value : "+jsonMap.get(key)); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 

    } 

    /** 
    * @param String : partialJsonData 
    * @return hasmap with all key elements 
    * */ 

    private HashMap<String,String> parseJsonDataAndFetchAllValues(String partialJsonData) { 
     HashMap<String,String>jsonMap = new HashMap<String,String>(); 
     JsonElement jelement = null; 
     JsonObject jsonObject = null; 
     try { 
      JsonParser jsonParser = new JsonParser(); 
      jelement = jsonParser.parse(partialJsonData); 
      jsonObject = jelement.getAsJsonObject(); 

      jsonObject = new JsonParser().parse(partialJsonData).getAsJsonObject(); 
      JsonArray jsonArray = jsonObject.getAsJsonArray("card"); 
      for (Object object : jsonArray) { 
       JsonObject aJson = (JsonObject) object; 
       String name = aJson.getAsJsonPrimitive("Name").toString().replaceAll("^\"|\"$", ""); 
       String place = aJson.getAsJsonPrimitive("place").toString().replaceAll("^\"|\"$", ""); 
       //System.out.println(name); 
       //System.out.println(place); 
       jsonMap.put(name, place); 
      }   
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     return jsonMap; 
    } 

    /** 
    * 
    * @param fileName 
    * @return string data 
    * @throws IOException 
    */ 
    public String readFile(String fileName) throws IOException { 
     BufferedReader br = new BufferedReader(new FileReader(fileName)); 
     StringBuilder sb = null; 
     try { 
      sb = new StringBuilder(); 
      String line = br.readLine(); 

      while (line != null) { 
       sb.append(line); 
       line = br.readLine(); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } finally { 
      br.close(); 
     } 
     return sb.toString(); 
    } 
}
