You are given a spring boot application $($version $2\mathrm{.}0\mathrm{.}5)$ with spring boot$-$starter$-$data$-$jpa module included. Database access is fully configured.

The database contains table "person$\_$data" with columns:

id $($bigint$)$

first$\_$name $($varchar$)$

last$\_$name $($varchar$)$

All columns are not nullable.

Tasks

Implement method getFullName in Person class, so that it would return full name for given entity. For example: "John Smith" $($when first$\_$name$=$John, last$\_$name$=$Smith$)$

Register PersonService class as spring bean

$$ Implement method findAll in PersonService. It should return all entities from database
