[Spring boot] spring boot based redis pipeline pipeline, bulk operations redis command

 

 

spring boot 2.x 

Use RedisTemplate operation

===================================

2.redisConfig need to add spring autoconfiguration

/**

 * @date 2019/5/27 16:13
 */
@Configuration
@AutoConfigureAfter(RedisAutoConfiguration.class)
public class RedisConfig {



    @Bean
    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {
        RedisTemplate redisTemplate = new RedisTemplate();
        redisTemplate.setConnectionFactory(factory);
        RedisSerializer keySerializer = new StringRedisSerializer();
//        = New new GenericJackson2JsonRedisSerializer ValueSerializer RedisSerializer ();
         // Key string using deserialized 
        redisTemplate.setKeySerializer (keySerializer);
         // value also takes a string deserialized
         @ reasons: pipeline operation, the operation of a batch command redis , various types of command returns may vary
         // may be a Boolean type may be of type String may be byte [] type String according to the results thus uniform treatment 
        redisTemplate.setValueSerializer (keySerializer);
         return redisTemplate; 
    }
