RedisTemplate Spring boot

Question

I am going to store my token in redis

RedisConfig

@Configuration
@EnableCaching
public class RedisConfig {

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


        JedisConnectionFactory jedisConnectionFactory = new JedisConnectionFactory(redisStandaloneConfiguration);
        return jedisConnectionFactory;
    }

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

Service

final var st =AuthenticationSuccessDto
                .builder()
                .accessToken(jwtUtils.generateAccessToken(user))
                .refreshToken(jwtUtils.generateRefreshToken(user))
                .tokenType("Bearer")
                .user(user)
                .expiresIn(TimeUnit.SECONDS.toSeconds(60)).build();

        try {
            redisTemplate.opsForHash().put(KEY,"1",st.getAccessToken());
        } catch (Exception e) {
            e.printStackTrace();
            throw new Exception();
        }

        return st;
    }

throws an exception java.lang.NoSuchMethodError: 'long redis.clients.jedis.Jedis.hset(byte[], byte[], byte[])'

I need to convert string to bytes? help plz

You can also have Spring Boot automatically generate the connection to Redis based on your.yml or a.properties file. You just need to add the following to your application.yml:

spring:
  redis:
    host: localhost
    port : '6379'

Everything worked for me when I changed the connection to the redis from JedisConnectionFactory to LettuceConnectionFactory

@Bean
    public LettuceConnectionFactory redisStandAloneConnectionFactory() {
        return new LettuceConnectionFactory(new RedisStandaloneConfiguration("127.0.0.1", 6379));
    }
