Redis学习笔记五 -- 指定序列化的方式

Springboot操作Redis时，发现key值出现 \xac\xed\x00\x05t\x00\tb

今天使用Spring Boot Data 操作Redis时，发现key值出现 \xac\xed\x00\x05t\x00\tb，但不影响程序读写，查询资料发现RedisTemplate 默认的序列化方式为 JdkSerializeable, StringRedisTemplate 的默认序列化方式为 StringRedisSerializer

话不多说，上解决方案：

其实就是指定序列化的方式，默认是 JdkSerializeable 是以二进制数组方式存储，内容没有可读性。

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

        // 使用Jackson2JsonRedisSerialize 替换默认序列化
        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);

        // 设置value的序列化规则和 key的序列化规则
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

    @Bean(name = "redisTemplateString")
    public RedisTemplate getRedisTemplate(RedisConnectionFactory factory) {
        RedisTemplate redisTemplate = new RedisTemplate<>();
        redisTemplate.setConnectionFactory(factory);
        // key的序列化类型
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        // value的序列化类型
        redisTemplate.setValueSerializer(new StringRedisSerializer());
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setDefaultSerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }

Jackson2JsonRedisSerializer效率最高
