Okay, let's dive deep into using Spring JDBC Template for calling Stored Procedures. This tutorial aims to be comprehensive, covering various scenarios and best practices.

*Spring JDBC Template: A Quick Overview*

Spring JDBC Template is a central class in the Spring Framework that simplifies JDBC operations. It handles resource management (connections, statements, result sets) and exception handling, reducing boilerplate code and improving the overall robustness of your JDBC interactions. When calling stored procedures, it provides a clean and organized way to define input parameters, execute the procedure, and process the output.

*Why Use JDBC Template for Stored Procedures?*

*Simplified Code:* Reduces repetitive JDBC boilerplate.
*Exception Handling:* Converts JDBC exceptions into Spring's consistent DataAccessException hierarchy.
*Resource Management:* Ensures proper connection and resource cleanup.
*Parameter Handling:* Provides mechanisms for mapping parameters using Java objects or `SqlParameter` and `SqlOutParameter` definitions.
*Type Safety:* Offers type-safe parameter binding.
*Transaction Management:* Seamless integration with Spring's transaction management system.
*Abstraction:* Decouples your code from specific JDBC implementations.

*Steps to Call a Stored Procedure using Spring JDBC Template*

Here's the general process, which we'll break down with examples:

1. *Set up the DataSource:* Configure a DataSource to connect to your database. This is the foundation for all JDBC interactions.
2. *Create the JdbcTemplate:* Instantiate a `JdbcTemplate` and associate it with the DataSource.
3. *Define the Stored Procedure:* Create a `StoredProcedure` object and configure it to match your database's stored procedure. This includes defining the name of the procedure, the input parameters, and the output parameters.
4. *Execute the Stored Procedure:* Call the `execute` method of the `StoredPro ...
