Spring aims to deliver on many of the promises of the J2EE framework, but in a less invasive and more productive manner.

Spring’s JDBC abstraction layer eliminates much of the repetitive coding normally associated with even simple SQL queries. The abstraction layer includes a StoredProcedure class that can be used to incorporate stored procedure calls into a Spring application. In this section we will provide a brief overview of how to access a MySQL stored procedure from within a Spring application.

The first result set contains a list of employees in that department, and the second contains a list of customers associated with the department.
