Lettuce 客户端自定义 RedisTemplate

背景：公司项目有两个 redis，一个是 sso 使用，一个是业务使用，为了区分，需要自定义 RedisTemplate

1. 自定义 RedisTemplate

import org.springframework.data.redis.core.StringRedisTemplate;

/**
 * @author liuyuan
 * @version ItemBuyerRedisTemplate.java, v 0.1 2024-03-15 16:27
 */
public class ItemBuyerRedisTemplate extends StringRedisTemplate {
}

2. 配置 RedisTemplate

import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.autoconfigure.condition.ConditionalOnSingleCandidate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.connection.RedisStandaloneConfiguration;
import org.springframework.data.redis.connection.lettuce.LettuceConnectionFactory;
import org.springframework.data.redis.core.StringRedisTemplate;

/**
 * @author liuyuan
 * @version ItemRedisConfiguration.java, v 0.1 2024-03-15 15:49
 */
@Configuration
public class ItemRedisConfiguration {

    @Value("${item.buyer_redis_host}")
    private String buyerRedisHost;
    @Value("${spring-redis-port:6379}")
    private int buyerRedisPort;
    @Value("${spring-redis-database:1}")
    private int buyerRedisDatabase;

    @Bean
    public ItemBuyerRedisTemplate itemBuyerRedisTemplate() {

        RedisStandaloneConfiguration redisStandaloneConfiguration = new RedisStandaloneConfiguration();
        redisStandaloneConfiguration.setHostName(buyerRedisHost);
        redisStandaloneConfiguration.setPort(buyerRedisPort);
        redisStandaloneConfiguration.setDatabase(buyerRedisDatabase);
        LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory(redisStandaloneConfiguration);
        // 初始化
        lettuceConnectionFactory.afterPropertiesSet();

        ItemBuyerRedisTemplate stringRedisTemplate = new ItemBuyerRedisTemplate();
        stringRedisTemplate.setConnectionFactory(lettuceConnectionFactory);
        return stringRedisTemplate;
    }

    @Primary
    @Bean
    @ConditionalOnSingleCandidate(RedisConnectionFactory.class)
    public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
        return new StringRedisTemplate(redisConnectionFactory);
    }
}
