How to Store Spring Boot Application Metrics in InfluxDB
Please note: The H2 database was chosen for simplicity. You can replace it with any other database technology and use the Spring Boot JPA to connect. The demo application will still work.

How to write a native query in spring boot jpa(postgres) which has "where in" check on composite columns?
What you are trying to do is not supported in JPA/JPQL or Spring Data (see here) Not even all databases support that syntax as far as I'm aware. You either need to concat the columns or add functionality to do this yourself, perhaps a Hibernate UserType will work.

How do access sql through java in the real world?
If you go with hibernate note that there are a few different ways to use it. It can be used standalone and it can be used as a JPA implementation. If you use Spring and use hibernate as a JPA implementation then a popular Spring data layer abstraction is Spring Data which has JPA support with its Spring Data JPA library (https://spring.io/projects/spring-data-jpa)
What are some alternatives?

jOOQ - jOOQ is the best way to write SQL in Java
purefun - Functional Programming library for Java
spring-data-r2dbc - Provide support to increase developer productivity in Java when using Reactive Relational Database Connectivity. Uses familiar Spring concepts such as a DatabaseClient for core API usage and lightweight repository style data access.
OrmLite - Core ORMLite functionality that provides a lite Java ORM in conjunction with ormlite-jdbc or ormlite-android
