+## Part 3: JPA
+ 
+In this section we're going to re-create our service class using JPA. 
+
+Start by breaking your `PersonService` class into an interface and implementation eg: `interface PersonService` and `class jdbcPersonServiceImpl`. Place the `@Service` annotation on the implementation class.
+
+Now create a new class that implements the PersonService, this time with JPA. Once you annotate this class with @Service you will get an error when you start spring -- you can fix this by annotation the service you want to use with `@Primary` -- This tells Spring that if there are multiple beans competing for autowiring, the one marked with `@Primary` should be used (this won't work if multiple competing beans are marked `@Primary`
 
+Implement all of the methods found in your `PersonService` interface in this new JPA-based service. You won't have to change your controller at all if you are autowiring a reference to a `PersonService` - Spring will automatically inject the `@Primary`-annotated implementation of `PersonService`
 
+Remember that you won't be using the Jdbc service or any `JdbcTemplate` objects in this part of the lab.
