Springboot 2.0 如何修改redis序列器

springboot 2.0以前整合redis存入key-value時，客戶端連接redis時候key是一長串的亂碼，由於使用了默認的序列器導致的，這就需要我們修改默認配置的序列器。

springboot 2.0以前整合redis有專門的redis配置管理器修改默認的序列器。

import com.fasterxml.jackson.annotation.PropertyAccessor;

@SpringBootApplication

public class LiveAppApplication {

    public static void main(String[] args) {
        SpringApplication.run(LiveAppApplication.class, args);
    }
    
    @Bean
    public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        // 使用Jackson2JsonRedisSerialize 替換默認序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        objectMapper.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);

        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);

        // 設置value的序列化規則和 key的序列化規則
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
    
}
