When configuring a Jedis Pool in Spring Boot, it is usually necessary to first import the Jedis dependency.

  1. Add the Jedis dependency.
<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
</dependency>
  1. Configure Redis connection information in the application.properties or application.yml file.
spring.redis.host=127.0.0.1
spring.redis.port=6379
spring.redis.password=
spring.redis.jedis.pool.max-active=8
spring.redis.jedis.pool.max-idle=8
spring.redis.jedis.pool.min-idle=0
spring.redis.jedis.pool.max-wait=-1
  1. Create a Jedis configuration class:
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.jedis.JedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class JedisConfig {

    @Bean
    public JedisConnectionFactory jedisConnectionFactory() {
        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory();
        jedisConnectionFactory.setHostName("127.0.0.1");
        jedisConnectionFactory.setPort(6379);
        return jedisConnectionFactory;
    }

    @Bean
    public RedisTemplate<String, String> redisTemplate() {
        RedisTemplate<String, String> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(jedisConnectionFactory());
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new StringRedisSerializer());
        return redisTemplate;
    }
}

This allows configuring and using Jedis Pool to connect to the Redis database. In other classes, you can inject RedisTemplate using the @Autowired annotation and then use it to operate on Redis data.
