A Spring Boot microservice to provide alerts based on location.

The current implementation allows providing a country name, a state name and a specific date. The returned result, will be a measures recommendation based on the current number of new cases in that region.

• Port: 9090
• Endpoint: /status/
• Request: GET
• Path variables: /{country}/{state}/{YYYY-MM-DD}/

http://localhost:9090/status/Germany/Berlin

The main source API for this implementation will be https://covid19tracking.narrativa.com/index_en.html

  • Basic usage

      import jsonij.Value;
      import jsonij.parser.JSONParser;
      import jsonij.parser.ParserException;
      
      public class json {
          public static void main(String[] arg){
              // Create a new parser object
              JSONParser parser = new JSONParser();
              // Mock a jason response from a REST endpoint
              String JsonResponse = "{\"key\":[{\"imdKey\":55},1,2.3,0.4,-5,-5.92,0.001E1,-0.045E45,987654321], \"key2\":{\"key21\":1,\"key22\":2}}";
              // Parse the response
              Value jsonBody = parser.parse(JsonResponse);
              // Extract a nested value
              Value nestedValue = jsonBody.get("key").get(0).get("imdKey");
              // Type case the response to string
              String stringValue = String.valueOf(jsonBody);
              // Print the values.  Note: you can use/print the value directly.
              System.out.println("The raw response value is " + stringValue + "\nThe nested value extracted is " + nestedValue);
          }
      }

In order to the level correctly, take the path from the root and use . as a separator till you reach the package name.
Levels: TRACE, DEBUG, INFO, WARN, ERROR, FATAL, OFF .

In the application.yaml file add the following:

logging:
  level:
    com.nexthink.mnt.covidalertservice.service: DEBUG
