Figure 16-2. Entering details for a Spring MVC project
Upon completion, STS will create a web project with the required dependencies, including the
Spring MVC module.
Implementing the Service Layer for the Samples
We want to show you some more practical samples instead of a simple "Hello World" application. So, we
will implement a simple contact information service (like the one in previous chapters) using JPA and
then expose its services to remote clients. This section discusses how to implement the service layer.
Adding Required Dependencies for the JPA Backend
We need to add the required dependencies to the project. Table 16-1 shows the dependencies required
for implementing a service layer with JPA 2 and Hibernate as the persistence provider. Also, Spring Data
JPA will be used. In addition, verify that the project is using Spring 3.1.
