Redis annotation

@Autowired
private StringRedisTemplate redisTemplate;

 @Autowired
 private RedisTemplate redisTemplate;

  The upper and lower ones are the same, but using the following one will cause garbled code. You have to use  

@Configuration
public class RedisConfig {

    @Bean(name = "redisTemplate")
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> template = new RedisTemplate<>();
        template.setConnectionFactory(redisConnectionFactory);

        // Customized    Serialization tools customized for values 
        Jackson2JsonRedisSerializer jacksonSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jacksonSerializer.setObjectMapper(om);
        // To key Set the serialization tool 
        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // Set up customized serialization tools 
        //  Using annotations @Bean return RedisTemplate When , Simultaneous configuration hashKey And hashValue How to serialize .
        // key use String How to serialize 
        template.setKeySerializer(stringRedisSerializer);
        // value The serialization method adopts jackson
        template.setValueSerializer(jacksonSerializer);
        // hash Of key Also used String How to serialize 
        template.setHashKeySerializer(stringRedisSerializer);
        // hash Of value The serialization method adopts jackson
        template.setHashValueSerializer(jacksonSerializer);
        template.afterPropertiesSet();
        // Customization ends 
        return template;
    }

}

ListOperations、ValueOperations、SetOperations、ZSetOperations、HashOperations How to use the interface 

​​​​​​​@Resource(name="redisTemplate")
 private ValueOperations valueOperations;

And so on .

Why use Resource Annotation is because  ValueOperations yes StringRedisTemplate Subclasses of

 This is a redisTemplate elective  

 ValueOperations<String, String> ValueOperations1 = redisTemplate.opsForValue();

This is the choice redisTemplate.opforValue(). Things will be found with the following direct use  ValueOperations It's the same

 

  So choose ValueOperations Yes, I skipped redisTemplate.opforValue(). But the results are the same
