SpringBoot2.x配置JsonRedisSerializer

Posted 2021-02-08 brx_blog

@Configurationpublic class SpringCacheRedisConfig {
   
    @Bean
    public RedisCacheManager cacheManager(RedisConnectionFactory factory) {
        RedisSerializer<String> redisSerializer = new StringRedisSerializer();
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);

        //解决查询缓存转换异常的问题
        ObjectMapper om = new ObjectMapper();
        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
        jackson2JsonRedisSerializer.setObjectMapper(om);

        // 配置序列化（解决乱码的问题）
        RedisCacheConfiguration config = RedisCacheConfiguration.defaultCacheConfig()
                .entryTtl(timeToLive)
                .serializeKeysWith(RedisSerializationContext.SerializationPair.fromSerializer(redisSerializer))
                .serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(jackson2JsonRedisSerializer))
                .disableCachingNullValues();

        RedisCacheManager cacheManager = RedisCacheManager.builder(factory)
                .cacheDefaults(config)
                .build();
        return cacheManager;
    }

//给redisTemplate配置json序列化

@Bean
public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory){
    RedisTemplate redisTemplate = new RedisTemplate();
    redisTemplate.setDefaultSerializer(RedisSerializer.json());
    redisTemplate.setConnectionFactory(redisConnectionFactory);
    return redisTemplate;
}

这样就可以解决，使用redisTemplate或redisCacheManager操作k-v，导致key：x0x0x00x000key，value：乱码
比如：

Order order = orderMapper.selectOrderByOrderId(Long.parseLong(id));
redisTemplate.opsForValue().set("testbrx",order);//
redisTemplate1.opsForValue().set("asda",order);
System.out.println(redisTemplate1.opsForValue().get("asda"));
Cache cache = xcacheManager.getCache("h::1");
if (cache!=null) {
    System.out.println(cache.getName());
    cache.put("2","asdasdasdasd");
    System.out.println(cache.get("2",String.class));
    cache.put("3",order);
    System.out.println(cache.get("3",Order.class));
}
