Spring-data-redis配置Fastjson序列化方式

前言

项目中由于使用FastJson替换Jackon为默认Json序列化方式，配置redis使用Fastjson进行序列化

序列化配置

redis传入的序列化器必须实现RedisSerializer接口：

    public void setValueSerializer(RedisSerializer serializer) {
        this.valueSerializer = serializer;
    }

定义FastJson序列化器：

public class FastJson2JsonRedisSerializer implements RedisSerializer {

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

    private Class clazz;

    public FastJson2JsonRedisSerializer(Class 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);
    }

}

设置RedisTemplate的序列化方式

    @Configuration
    public class RedisConfig {


        @Bean
        public RedisSerializer fastJson2JsonRedisSerializer() {
            return new FastJson2JsonRedisSerializer
