How do you handle Oracle stored procedures in Spring Boot?
Table of Contents
Introduction
Stored procedures in Oracle are reusable blocks of PL/SQL code that encapsulate business logic. Integrating stored procedures in a Spring Boot application allows efficient database interaction and centralized logic execution. This guide explores how to handle Oracle stored procedures using JdbcTemplate and SimpleJdbcCall in Spring Boot.
Methods to Handle Oracle Stored Procedures
1. Using JdbcTemplate
The JdbcTemplate class enables straightforward execution of stored procedures using SQL callable statements.
Example: Call a Stored Procedure
2. Using SimpleJdbcCall
SimpleJdbcCall is a more abstract and declarative way to call stored procedures. It supports input, output, and in-out parameters with type mapping.
Example: Call a Procedure with Input and Output Parameters
Practical Examples
Example 1: Using SimpleJdbcCall with Multiple Parameters
Stored procedure:
Java code:
Example 2: Error Handling
Conclusion
Handling Oracle stored procedures in Spring Boot is straightforward using JdbcTemplate for direct calls or SimpleJdbcCall for a more declarative approach. Both methods allow efficient execution of business logic stored in the database. By leveraging these tools, you can ensure robust and maintainable interactions with Oracle stored procedures in your Spring Boot applications.
