xACxEDx00x05tx00x0redis存key出现

在使用RedisTemplate存key的时候发现在redis的key是这样的:

在RedisTemplate源码里面可以知道默认序列化是使用的JdkSerializationRedisSerializer就是jdk自己的序列化方式


那就明了了,我们在创建的RedisTemplate指定序列化方式为阿里的FastJson2JsonRedisSerializer就可以了:
一开始没有指定:

需要引入阿里的fastjson pom依赖 ;新增FastJson2JsonRedisSerializer类,:

public class FastJson2JsonRedisSerializer<T> implements RedisSerializer<T> {

    public static final Charset DEFAULT_CHARSET = Charset.forName("UTF-8");

    private Class<T> clazz;

    public FastJson2JsonRedisSerializer(Class<T> clazz) {
        super();
        this.clazz = clazz;
    }

    @Override
    public byte[] serialize(T t) throws SerializationException {
        if (t == null) {
            return new byte[0];
        }
        return JSON.toJSONString(t, SerializerFeature.WriteClassName).getBytes(DEFAULT_CHARSET);
    }

    @Override
    public T deserialize(byte[] bytes) throws SerializationException {
        if (bytes == null || bytes.length <= 0) {
            return null;
        }
        String str = new String(bytes, DEFAULT_CHARSET);

        return (T) JSON.parseObject(str, clazz);
    }

}

添加序列化类

创建RedisTemplate的时候指定序列化:

   @Bean
    public RedisTemplate taskRedisTemplate(RedisConnectionFactory redisConnectionFactory) {
        RedisTemplate<Object, Object> configRedisTemplate = new RedisTemplate<>();
        configRedisTemplate.setValueSerializer(fastJson2JsonRedisSerializer());
        configRedisTemplate.setHashValueSerializer(fastJson2JsonRedisSerializer());
        configRedisTemplate.setKeySerializer(new StringRedisSerializer());
        configRedisTemplate.setHashKeySerializer(new StringRedisSerializer());
        configRedisTemplate.setConnectionFactory(redisConnectionFactory);
        return configRedisTemplate;
    }

但是测试发现还是一样的:试了很多总都是不行,最后想了想还是直接使用StringRedisTemplate,不使用RedisTemplate

 public StringRedisTemplate stringRedisTemplate() {
        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(rddConnectionFactory());
        return template;
    }

这样就好了…
