SpringBoot之redis使用FastJSON自定义序列化_parserconfig 自定义序列化

1.1、使用自定义FastJSON来序列化你的对象 注意如果不配置白名单地址将会出现com.alibaba.fastjson.JSONException: autoType is not support具体可以看看我的转载文章https://blog.csdn.net/qq_37892957/article/details/89303903

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;
    }
    //配置白名单 地址是实体类包地址
    static {
        ParserConfig.getGlobalInstance().addAccept("com.bean.springcloudcommon.model");
    }
    @Override
    public byte[] serialize(T o) throws SerializationException {
        if (o == null) {
            return new byte[0];
        }
        return JSON.toJSONString(o, 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);
    }
}

1.2、配置RedisConfig

@Configuration
public class RedisConfig {
    @Bean
    public RedisSerializer fastJson2JsonRedisSerializer() {
        return new FastJson2JsonRedisSerializer<Object>(Object.class);
    }
 
    @Bean
    public RedisTemplate initRedisTemplate(RedisConnectionFactory redisConnectionFactory, RedisSerializer fastJson2JsonRedisSerializer) throws Exception {
        RedisTemplate redisTemplate = new RedisTemplate();
        redisTemplate.setConnectionFactory(redisConnectionFactory);
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(fastJson2JsonRedisSerializer);
        redisTemplate.setHashKeySerializer(new StringRedisSerializer());
        redisTemplate.setHashValueSerializer(fastJson2JsonRedisSerializer);
        redisTemplate.setDefaultSerializer(new StringRedisSerializer());
        redisTemplate.afterPropertiesSet();
        return redisTemplate;
    }
}
