   > spring security Authentication 对象在反序列化的时候，有时会出现一些错误，主要错误体现在，在反序列化时，构造参数不能为空等条件，介于此，dubbo 内部加入了默认对象的一些反序列化器，可以查看ObjectMapperCodec这个类。如果是自定义认证对象，可以通过ObjectMapperCodecCustomer扩展反序列化方式，具体反序列化器实现参考 UsernamePasswordAuthenticationTokenDeserializer
   
   我修改了增加了mixin，但是MyObjectMapperCustomer这个类dubbo怎么加载
   ```java
   public class MyObjectMapperCustomer implements ObjectMapperCodecCustomer {
       @Override
       public void customize(ObjectMapperCodec objectMapperCodec) {
           objectMapperCodec.configureMapper(objectMapper -> {
               objectMapper.addMixIn(PasswordAuthenticationToken.class, PasswordAuthenticationTokenMixin.class);
           });
       }
   }
   ```
