引入对应的 pom 坐标

配置一个配置类

@Configuration
@EnableCaching
public class LettuceRedisConfig {

    @Bean
    public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        return redisTemplate;
    }
}

开始存放

@Autowired
private RedisTemplate redisTemplate;

@Override
public void getRedisListGoods() {
    //查询到的集合
    List<GoodsVo> list = getGoods();
    //获取 redis 操作对象
    //泛型类型(key,对应的实体类)
    ListOperations<String, GoodsVo> ops = redisTemplate.opsForList();
    //开始存放
    list.forEach(k -> {
        ops.leftPush(k.getGoodsName(), k);
    });
}

模糊查询

/**
 * 模糊查询
 * @param matchKey 关键字
 * @return
 */
@Override
public List<GoodsVo> scan(String matchKey) {
    //搜索到的 key 值存放的集合
    Set<String> keys = new LinkedHashSet<>();
    //开始搜索,数据存储在上面的 set 集合中
    redisTemplate.execute((RedisConnection connection) -> {
        try (Cursor<byte[]> cursor = connection.scan(
                ScanOptions.scanOptions()
                        .count(Long.MAX_VALUE)
                        //* 号通配符的作用
                        .match("*"+matchKey+"*")
                        .build()
        )) {
            cursor.forEachRemaining(item -> {
                keys.add(RedisSerializer.string().deserialize(item));
            });
            return keys;
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    });
    //获取一个 redis 操作对象
    ListOperations ops = redisTemplate.opsForList();
    //设置一个存放查询数据的集合
    List<GoodsVo> voList = new ArrayList<>();
    //遍历搜索的 key 并存放到集合中
    keys.forEach(key ->{
        voList.add((GoodsVo) ops.index(key,-1));
    });
    return voList;
}
