Is there any good generic JPA DAO implemenation?
dao, java, jpa
Solution
You could take a look into the Spring Data JPA.
A few new concepts were introduced into Spring Data JPA, for instance the Query creation based on the method name, so you can declare a method like `findById(String id)` and the "generic" implementation will interpret the method's name and execute something like `select Entity from Entity where id = 'given string'`
Methods like `findByNameAndLastName(String name, String lastName)` or even `findByNameOrInternalId(String name, int internalId)` are supported too.
Problem
According this article, generic JPA DAO(Data Access Object) is a pretty nice pattern. Is there any good implementation?
