We will go through the process of integrating Redis with a Spring Boot application step by step. You will learn how to correctly add dependencies and configure connection parameters.

Adding Dependencies

To integrate Redis into the project, you need to add the necessary dependencies to your application's build system.

For Maven, add the following code to the pom.xml file:

python
9
1
2
3
4
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

For Gradle, add the following dependency to your build.gradle file:

python
implementation 'org.springframework.boot:spring-boot-starter-data-redis'

This dependency includes the components required to work with Redis, enabling the Spring application to use Redis for data storage, caching, and other distributed data operations. It simplifies interaction with Redis through Spring annotations and components, making it easier to work with the database and caching.

Configuration

To configure Redis as a cache, all you need to do is add a single line to the application.properties file. You'll specify that Redis will be used for caching.

python
spring.cache.type=redis

The configuration in the application.properties file for Spring Boot specifies the use of Redis as the caching mechanism with the line spring.cache.type=redis. This integrates Redis into the application, allowing for efficient data storage in the cache.

Summary

As a result of these steps, we have successfully integrated Redis into the Spring Boot application, enabling the connection to a Redis server and performing data operations. The application is now ready to use Redis as a cache.
