Querying for Data in a Java Spring App - Alternatives

1. Create a method with a name including all attributes you want to query by in your PersonRepository interface that implements CrudRepository<> (or PagingAndSortingRepository<>)
2. Create a Specification object and use Spring findAll to find all records matching the Specification.
3. Use @Query in the PersonRepository and define the query using JQL
4. Use GraphQL (see for example https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#core.extensions.querydsl)
