spring-data - StringRedisConnection 的 Spring Bean 范围

Question

我有以下两个 Spring Data Redis 的 bean 定义。我似乎找不到相关文档来确定 Web 应用程序的这些 bean 的范围（单例、请求或会话）。

@Bean
public StringRedisTemplate redisTemplate() throws Exception {
    StringRedisTemplate redisTemplate = new StringRedisTemplate();
    redisTemplate.setConnectionFactory(jedisConnectionFactory());
    return redisTemplate;
}

@Bean
public StringRedisConnection stringRedisConnection() throws Exception {
    return new DefaultStringRedisConnection(redisTemplate().getConnectionFactory().getConnection());
}

感谢@Christoph Strobl 推荐这里是我目前使用的实现

  public  List<String> testAutoComplete(String key,String query, int limitCount){
        StringRedisSerializer serializer = new StringRedisSerializer();
        RedisZSetCommands.Range range = Range.range();
        range.gt(query);
        RedisZSetCommands.Limit limit = new RedisZSetCommands.Limit();
        limit.count(limitCount);
       return template.execute(new RedisCallback< List<String>>() {
            public  List<String> doInRedis(RedisConnection connection) {
                Set<byte[]> results = connection.zRangeByLex(serializer.serialize(key), range,limit);
                List<String> resultAsString = new ArrayList<String>();
                for(byte[] result : results){
                    resultAsString.add(serializer.deserialize(result));
                }
                return resultAsString;
            }
        },false); 
    }
