title: No accessor to set property private final java.util.Map org.springframework.boot.configurationprocessor.json.JSONObject.nameValuePairs
body: <p>I'm trying to use Mongo DB for one of Java application using Spring boot. I have created model for my document and then using Mongo Repository and then trying to use JSONObject as one of the property in my document. While inserting a document into the collection works fine but while trying to access it I'm getting the exception. Below is my code please let me know if I'm making any mistake. Thanks in advance. </p>
  
  <pre><code>@Document(collection="AppSetting")
  public class AppSetting {
  
      @Id
      private ObjectId id;
      private String name;
      private JSONObject value;
  
  
      /**
       * @return the name
       */
      public String getName() {
          return name;
      }
      /**
       * @param name the name to set
       */
      public void setName(String name) {
          this.name = name;
      }
  
      /**
       * @return the value
       */
      public JSONObject getValue() {
          return value;
      }
      /**
       * @param value the value to set
       */
      public void setValue(JSONObject value) {
          this.value = value;
      }
  }
  </code></pre>
  
  <p>Repository:</p>
  
  <pre><code>public interface AppSettingRepository extends MongoRepository&lt;AppSetting, ObjectId&gt;{
      AppSetting findByName(String name);
  }
  </code></pre>
  
  <p>Finally the service where I'm performing the operation is goes here:</p>
  
  <pre><code>@RestController
  @RequestMapping("/apidoc/appsetting")
  public class AppSettingController {
  
      @Autowired
      AppSettingRepository appRepo;
  
      @RequestMapping(method = RequestMethod.POST, value = "/updateConnector/{appname}")
      public ResponseEntity&lt;String&gt; updateAvailableConnector(@PathVariable("appname") final String appName,
              @RequestBody final Map&lt;String, String&gt; connectors
      ) {
  
          if( connectors == null || appName == null) {
              return null;
          }
  
          AppSetting setting = appRepo.findByName(appName);
  
  
          if(setting == null) {
              setting = new AppSetting();
              setting.setName(appName);
          }
  
          if(setting.getValue() == null)
              setting.setValue(new JSONObject());
  
          // Update Existing Connectors
          for( String key : connectors.keySet()) {
              try {
                  setting.getValue().put(key, connectors.get(key));
              } catch (JSONException e) {
                  // TODO Auto-generated catch block
                  e.printStackTrace();
              }
          }
  
          appRepo.save(setting);
          return null;
      }
