JdbcTemplate

• Spring Framework
• JDBC

Overview

Basic persistence with JDBC is supported by the Spring Framework with JdbcTemplate. JdbcTemplate provides the means by which developers can perform SQL operations against a relational database without the need to retort to verbose JDBC low-level API. With JdbcTemplate, the interaction with the database is reduced to specifying the query and how to map the result of the query to the domain model object.

Spring Boot Support

To add support for JdbcTemplate to a Spring Boot project, add the following starter dependency:

dependencies {
    implementation('org.springframework.boot:spring-boot-starter-jdbc')
}

JdbcTemplate needs a database to work with. This is how to add H2 support:

dependencies {
    runtimeOnly('com.h2database:h2')
}

JdbcTemplate-Based Repository

This is a JdbcTemplate-based concrete repository implementation that conceals from the application low-level data access details while exposing a domain model-typed API, represented by the example "IngredientRepository" interface.
