Configuring Application

   1. login to your sql host (localhost:3306, in my case)
   2. [Optional]Create a new user (iqvia)
   3. Note down the password (IqVia@542)
   4. Now login as this new user.
   5. Create a new Database (iqvia_messageScheduler)
   6. Dump the sql file provied at src/main/resources/database/quartzTables.sql into this database.
4. Update the src/main/resources/application.properties file
   1. spring.datasource.url
      • Specify the mysql host url (eg: localhost:3306)
      • Database Name created earlier (eg: iqvia_messageScheduler)

      • User to this above database(iqvia_messageScheduler) (eg: iqvia)
   3. spring.datasource.password
      • User Password (IqVia@542)
5. All set, run the file MessageSchedulerApplication.java as java application

Testing the application

We can use any REST client to test this application, I used curl

curl -X POST -H 'Content-Type: application/json' -i http://localhost:8080/schedulemessage --data '{
"content" : "Demo Message",
"deliveryTime" : "2020-07-19T17:32:16"
}'

Json data passed in request should have these 2 fields:

1. content - the message to be printed on console
2. deliveryTime - the time at which this message to be printed, in ISO-8601 format ,such as 2007-12-03T10:15:30

Empty message or past delivery time message is not accepted.
