Anyone read the book or learn the topics about Spring Data

[zach zhang]

I just check the contents of the book Spring Data.

It seems very interesting. Does anyone use ever Spring data, batch, integration and how do you feel about them?

I don't write any DAO code. For ex: I just relied on Spring Data JPA module to do the job for me and if needed few customization (easy)

Just download any Spring Data and experiment with it:

I use it all the time its great

Spring Data JPA is amazing. It makes it super easy to store entities in the database and do queries. You hardly have to write any code at all yourself.

You create a repository interface, but you don't have to write any implementation yourself - Spring will automatically generate the implementation. It is very smart, just by looking at the names of the methods you put in the interface it can automatically an implementation that does what you want.

For example, suppose you have a Customer entity and you want to have a method to find customers by last name. You create an interface that looks like this:

import java.util.List;

import org.springframework.data.repository.CrudRepository;

public interface CustomerRepository extends CrudRepository<Customer, Long> {

    List<Customer> findByLastName(String lastName);
}

and Spring will automatically generate the right implementation. It does this by looking at the method name; from "findByLastName" it automatically understands that you want to do a query like "select Customer c where c.lastName = ...". Besides this example, there are lots of other possibilities for which it can automatically generate the implementation for the methods.

See this tutorial and the reference documentation.
