redistemplate设置序列化的方式

redistemplate 默认的序列化方式是 JdkSerializationRedisSerializer , java操作时会产生乱码，故更改其序列化方式

（附加：StringRedisTemplate 的默认序列化方式为 StringRedisSerializer）

方法1：

@Bean
    public RedisTemplate<String, Object> getRedisTemplate(RedisConnectionFactory redisConnectionFactory){
        RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
        redisTemplate.setConnectionFactory(redisConnectionFactory);

        GenericJackson2JsonRedisSerializer genericJackson2JsonRedisSerializer = new GenericJackson2JsonRedisSerializer();

        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // 设置value的序列化规则和 key的序列化规则
        redisTemplate.setKeySerializer(stringRedisSerializer);
        redisTemplate.setValueSerializer(genericJackson2JsonRedisSerializer);

        redisTemplate.setHashKeySerializer(stringRedisSerializer);
        redisTemplate.setHashValueSerializer(genericJackson2JsonRedisSerializer);

        redisTemplate.setDefaultSerializer(genericJackson2JsonRedisSerializer);
        redisTemplate.setEnableDefaultSerializer(true);
        redisTemplate.afterPropertiesSet();
        return redisTemplate;

    }

方法2：

@Bean
public RedisTemplate<String,Object> redisTemplate(RedisConnectionFactory factory){
    RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
    redisTemplate.setConnectionFactory(factory);
    redisTemplate.setKeySerializer(new StringRedisSerializer()); // key的序列化类型

    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);
    redisTemplate.setValueSerializer(jackson2JsonRedisSerializer); // value的序列化类型
    redisTemplate.setHashKeySerializer(new StringRedisSerializer());
    redisTemplate.setHashValueSerializer(jackson2JsonRedisSerializer);
    redisTemplate.afterPropertiesSet();
    return redisTemplate;
}

注意：无论方法1还是方法2，都会有类的信息存储在redis里，本人习惯使用使用字符串，加fastjson进行处理。
