In this tutorial will talk about the Entity Creation. lets discuss what is the entity creation. Entity creation nothing but a table creation.in your core java application your create the database then create the table the same thing in spring called as entity.
Phone No creation there a rule imagen if you have more than 1 phone no you have to use json format.create a arraylist and use them.i attached the example below.
1 2 | @Type(type = "json") @Column(name = "contact_numbers",columnDefinition = "json") private ArrayList contactNumbers; |
in order to use them you have download the corresponding dependencies
go to the google and search maven vladmihalcea and get the corresponding dependencies.
then paste into your pom.xml
i attached the video below.that will explained every thing.
