Hi, I am creating Spring Boot Redis Application. Find my Maven dependencies.

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-data-redis</artifactId>

<version>2.0.4.RELEASE</version>

</dependency>

But it is not resolving JedisPoolConfig. I am getting error.

How to fix it?

JedisPoolConfig is needed when we use Jedis Configuration. In Spring Boot 2.0, spring-boot-starter-data-redis gives Lettuce dependency by default instead of Jedis. To use Jedis configuration, exclude Lettuce and add Jedis as following.

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
<exclusions>
    <exclusion>
    <groupId>io.lettuce</groupId>
    <artifactId>lettuce-core</artifactId>
    </exclusion>
</exclusions>
</dependency>
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
