在 Spring Boot 2.5.4 应用程序中 JedisClient 初始化时发生 ClassNotFoundException

Question

I have a Spring Boot 2.5.4 application in which I would like to add Redis and access it via Spring Data Redis.My current configuration looks like this:

RedisConfiguration.java

@Configuration

  private int port;

    redisConfiguration.setDatabase(database);
    redisConfiguration.setPassword(RedisPassword.of(password));

    JedisClientConfigurationBuilder jedisClientConfiguration = JedisClientConfiguration.builder();
    jedisClientConfiguration.connectTimeout(Duration.ofMillis(Long.parseLong(timeout)));

    return new JedisConnectionFactory(redisConfiguration, jedisClientConfiguration.build());
  }

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

for current configuration while application start I am receiving

So far I have tried manipulating the redis.clients and spring-boot-starter-data-redis versions by decreasing and increasing it but always problems with initialization occur. Every single tutorial which I found doesn't contain configuration for the new Spring Boot application version. I Will be grateful for suggestions on how to manipulate the pom.xml version of redis.clients and spring-boot-starter-data-redis to make the application starts again.

Answer 1

spring-boot-starter-data-redis<\/code> already includes jedis<\/code> as a dependency so you shouldn't add it to your pom.xml with a version that might not be compatible with your spring-boot-starter-data-redis<\/code> .

---

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-redis</artifactId>
  <version>2.5.1</version>
  <scope>compile</scope>
</dependency>

Answer 2

Spent several hours, so posting for spring boot versions 2.7.3 to be helpful for others.

spring-boot-starter-data-redis uses lettuce by default instead of jedis client. You would have to exclude lettuce and include jedis instead.

implementation ('org.springframework.boot:spring-boot-starter-data-redis') {
        exclude group: 'io.lettuce.lettuce-core'
    }
    implementation 'com.github.houbb:redis-client-jedis:0.0.3'```
