Spring Framework provides excellent support to call stored procedures from Java application. In fact there are multiple ways to call stored procedure in Spring Framework, e.g. you can use one of the query() method from JdbcTemplate to call stored procedures, or you can extend abstract class StoredProcedure to call stored procedures from Java. In this Java Spring tutorial, we will see second approach to call stored procedure. It's more object oriented, but same time requires more coding. StoredProcedure class allows you to declare IN and OUT parameters and call stored procedure using its various execute() method, which has protected access and can only be called from sub class. I personally prefer to implement StoredProcedure class as Inner class, if its tied up with one of DAO Object, e.g. in this case it nicely fit inside EmployeeDAO. Then you can provide convenient method to wrap stored procedure calls. In order to demonstrate, how to call stored procedures from spring based application, we will first create a simple stored proc using MySQL database, as shown below.
