Json比较异常：Can'；t在java中访问getJSONArray

我使用的代码：

 JSON1:
 {
   "array1": [
    {
      "id": "1",
      "Name": "Xytrex Co.",
      "Description": "Industrial Cleaning Supply Company",
      "Account Number": "ABC15797531",
      "Address": {
       "Permanent": {
       "Street": "st.road",
       "pin": "789723"
       },
        "Temporary": {
         "Street": "st.road",
         "pin": "789723"
       }
     }
   },

{
  "id": "2",
  "Name": "Xytrex Co.",
  "Description": "Industrial Cleaning Supply Company",
  "Account Number": "ABC15797531",
  "Address": {
    "Permanent": {
      "Street": "st.road",
      "pin": "789723"
    },
    "Temporary": {
      "pin": "789723"
    }
  }
}
 ]
 }

JSON2:

     {
   "array2": [
     {
      "id": "1",
      "Name": "Xytrex Co.",
      "Description": "Industrial Cleaning Supply Company",
      "Account Number": "ABC15797531",
      "Address": {
        "Permanent": {
          "Street": "st.road",
          "pin": "789723"
        },
        "Temporary": {
          "Street": "st.road",
          "pin": "789723"
        }
      }
   },

  {
     "id": "2",
     "Name": "Xytrex Co.",
    "Description": "Industrial Cleaning Supply Company",
    "Account Number": "ABC15797531",
        "Address": {
        "Permanent": {
        "Street": "st.road",
        "pin": "789723"
       },
       "Temporary": {
        "Street": "st.road",
        "pin": "789723"
       }
     }
   }
 ]
 }

我所期望的结果是，

id:“2”

下的

JSON1

中缺少键

Street

，或者类似的东西，它们提供了适当的信息，帮助我们识别缺少的键以执行

Junit

测试

我在IDE中得到的错误是

package com.company;

import com.google.gson.JsonArray;
import com.google.gson.JsonObject;
import org.skyscreamer.jsonassert.JSONAssert;
import org.skyscreamer.jsonassert.JSONCompareMode;
import com.google.gson.JsonParser;

import java.io.FileNotFoundException;
import java.io.FileReader;


public class Main {

public static void main(String[] args) throws FileNotFoundException {

    Main cmp = new Main();
    cmp.myTest();
}

public void myTest() throws FileNotFoundException {

     JsonParser Parser = new JsonParser();
     JsonObject obj1 = (JsonObject) Parser.parse(new 
 FileReader("/home/cloudera/Desktop/SampleJson/src/JSON1.json"));
    JsonArray array1 = obj1.getAsJsonArray("array1");
    JsonObject obj2 = (JsonObject)Parser.parse(new 
 FileReader("/home/cloudera/Desktop/SampleJson/src/JSON2.json"));
    JsonArray array2 = obj1.getAsJsonArray("array2");
    JSONAssert.assertEquals(array1, array2, JSONCompareMode.STRICT);
 }
}

请帮我解决这个问题。

我认为您对

JSONArray

对象类的初始化在这些行中似乎不正确

"java: cannot access org.json.JSONArray
  class file for org.json.JSONArray not found". 

您没有在方法

getAsJsonArray（）

中传递正确的参数。您传递了一个硬编码值

“array1”

和

“array2”

，该值不是要转换为

JSONArray

的正确值

您确定要从正确的包导入类吗？也许作为“com.google.gson.JsonArray”的导入应该类似于“org.json.something.JsonArray”@Stéphaneamar

org.json.JsonArray

也是一个类，可以在

json Simple

中找到。您确定从正确的包导入了类吗？也许作为“com.google.gson.JsonArray”的导入应该像“org.json.something.JsonArray”@StéphaneAmmar

org.json.JsonArray

也是一个类，它在

json Simple

中可用，不是硬编码值，这是我必须给这两个文件的名称。这不是硬编码值，这些是我必须给这两个文件起的名字。
