Spring Cloud里修改Redis的序列化方式

@Configuration
public class RedisTemplateConfig {

    @Autowired
    public RedisTemplateConfig(RedisTemplate redisTemplate) {
        //创建jackson的序列化方式
        Jackson2JsonRedisSerializer<Object> jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer<>(
                Object.class);
        ObjectMapper objectMapper = new ObjectMapper();
        //设置序列化时允许访问对象中的所有属性
        objectMapper.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
        //json转化时保存类的信息
        objectMapper.activateDefaultTyping(LaissezFaireSubTypeValidator.instance, ObjectMapper.DefaultTyping.NON_FINAL,
                JsonTypeInfo.As.WRAPPER_ARRAY);
        //修改jackson序列化的方式
        jackson2JsonRedisSerializer.setObjectMapper(objectMapper);
        StringRedisSerializer stringKeySerializer = new StringRedisSerializer();
        //修改key序列化为string序列化
        redisTemplate.setKeySerializer(stringKeySerializer);
        //将值得对象序列化转换为jackson序列化
        redisTemplate.setValueSerializer(jackson2JsonRedisSerializer);
        //设置hashkey的序列化为string序列化
        redisTemplate.setHashKeySerializer(stringKeySerializer);
        //设置hashvalue的序列化为jackson序列化
        redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
        //工厂创建redisTemplate对象之后在进行配置
        redisTemplate.afterPropertiesSet();
    }
}
