redis - 为什么redis-cli获取程序设置的对象的值总是nil

Question

我使用了 spring-data-redis 并将模板设置如下:

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



@Autowired
private RedisTemplate<String, Object> redisTemplate;
private ValueOperations<String, Object> valueOps;
public static final String CATEGORY="QUOTE"; 

public void save(String key, String value) {

    valueOps.set(key, value);
    logger.info("redis get key={}, value={}", key, get(key));
}   

当我运行代码时，它可以将值显示为字符串，

Aug 02, 2017 5:00:52 下午 com.web.service.QuoteRepo save
INFO: redis get key=QUOTE:932:324371:rem, value=4

当我去redis客户端的时候

$ ./redis-cli
127.0.0.1:6379>get QUOTE:932:324371:rem
(nil)

注意这行代码:

private ValueOperations<String, Object> valueOps;

您应该将模板作为 ValueOperations 注入(inject)。你忘记了这样的事情:

@resource(name="redisTemplate")
private ValueOperations<String, Object> valueOps;
