尝试替换请求json中的整数值(用于使用request.replace()的字符串)

Question

我们正在使用REST自动化Rest，在其中一些属性值需要在运行时被替换，在某些情况下可以是String，在另一些情况下可以是Integer。

请求json：

{
 "bInfo":{
  "bEx":9, //Need to replace Integer value here
  "oriDate":"2020-07-08"    

},     

"education":{
  "educationE":{
      "proCal":9, //Need to replace Integer value here
      "cutAmt":250, //Need to replace Integer value here
      "totalAmt":20 //Need to replace Integer value here
  },
  "educationInfo":{
      "educationPur":"purtest", //Need to replace String value here
      "educationStr":"Mu",
      "educationPro":"RT",
      "rec":"N",
      "oriDate":"2019-08-10"
  } 
  },  
  "educationRes":{  
     "pTest": "", //Set String value here
     "rTest":"",
     "sFl":""
 },   

"educationRResult":{
   "as":""

}, 

 "qualities":[{

 "qualitiesE":{
 "gt":10, //Need to replace Integer value here
 "oValue":10,
 "pPr":10,
 "oVa":7,
 "cIn":1,
 "rRatio":2    
 }
  },
  {    
"qualitiesE":{
 "gt":1000,
 "oValue":10,
 "pPr":2,
 "oVa":5,
 "cIn":200,
 "rRatio":1
 }
  },
  {
  "qualitiesE":{
 "gt":70,
 "oValue":25,
 "pPr":100,
 "oVa":7,
 "cIn":40,
 "rRatio":5    
  }
  }]      
} 

用于替换字符串的代码：“虚拟值”

request.replace("dummyvalue", "Test123");

O/P:工作成功。值替换为Test123

类似地，在同一个json中，需要用Integer: xyz值50替换值。

request.replace works only with String, if want to replace as Integer value tried

Declared String value = "50" as String and Tried

然后，它将字符串值替换为" 50“，因此当发送时请求失败，因为json有效负载期望该值为Integer 50。如果按以下方式尝试：

int amtIntValue = Integer.parseInt(50);

Then request.replace won't work

请指点。附加了尝试过的代码。

您可以在JsonObject中使用葛森；

// Required imports
import com.google.gson.Gson;
import com.google.gson.JsonObject;

    Gson gson = new Gson();

    // request is the json in the OP converted to a String
    JsonObject jsonObject = gson.fromJson(request, JsonObject.class);

    // Update bEx in bInfo
    jsonObject.getAsJsonObject("bInfo").add("bEx", gson.toJsonTree(555));

    // Update proCal,cutAmt and totalAmt in educationE
    jsonObject.getAsJsonObject("education").getAsJsonObject("educationE").add("proCal", gson.toJsonTree(555));
    jsonObject.getAsJsonObject("education").getAsJsonObject("educationE").add("cutAmt", gson.toJsonTree(555));
    jsonObject.getAsJsonObject("education").getAsJsonObject("educationE").add("totalAmt", gson.toJsonTree(555));

    // Update educationPur in educationInfo
    jsonObject.getAsJsonObject("education").getAsJsonObject("educationInfo").add("educationPur", gson.toJsonTree("educationPur_updated"));

    // Update pTest in educationRes
    jsonObject.getAsJsonObject("educationRes").add("pTest", gson.toJsonTree("pTest_updated"));

    // Update gt in the first item of the qualities JsonArray
    JsonObject qualitiesE = jsonObject.getAsJsonArray("qualities").get(0).getAsJsonObject();
    qualitiesE.get("qualitiesE").getAsJsonObject().add("gt", gson.toJsonTree(555));

    // Convert JsonObject back to String
    request = gson.toJson(jsonObject);

    System.out.println(request);

产出；{"bInfo":{"bEx":555，"oriDate":"2020-07-08"}，“教育”：{“educationE”：{“proCal”：555，"cutAmt":555，"totalAmt":555}，"educationStr":"Mu"，"educationPro":"RT"，"rec":"N"，“oriDate”：“2019-08-10”}"educationRes":{"pTest":"pTest_updated“、"rTest":"”、“sFl”：“}”、“educationRResult”：{“as”：“}”、“质量”：{“qualitiesE”：{“qualitiesE”：555、"oValue":10、"pPr":10、"oVa":7、"cIn":1、“rRatio”：2}、{"qualitiesE":{"gt":1000、"oValue":10、"pPr":2，"oVa":5，"cIn":200，“rRatio”：1}，{"qualitiesE":{"gt":70，"oValue":25，"pPr":100，"oVa":7，"cIn":40，“rRatio”：5}
