auto create json schema from database code example

Example: json schema generator

String json = "{\"sectors\": [{\"times\":[{\"intensity\":30," +
                "\"start\":{\"hour\":8,\"minute\":30},\"end\":{\"hour\":17,\"minute\":0}}," +

                "\"id\":\"dbea21eb-57b5-44c9-a953-f61816fd5876\"}]}";
        String result = JsonSchemaGenerator.outputAsString("Schedule", "this is a test", json);
