kennyliao1982 opened a new issue #2178: please consider supporting Java 8 Date/Time type when serializing with Kryo
URL: https://github.com/apache/incubator-dubbo/issues/2178
 
 
   ### Environment
   
   * Dubbo version: 2.6.2
   * Java version: 1.8
   
   I am using java.time.LocalDateTime and Dubbo complains "**class java.time.LocalDateTime has no zero-arg constructor and this will affect the serialization performance**", which is caused by Dubbo's wrapper class "**CompatibleKryo**"
   
   Any thoughts ??
   
   ```
   package com.alibaba.dubbo.common.serialize.kryo;
   
   import com.alibaba.dubbo.common.logger.Logger;
   import com.alibaba.dubbo.common.logger.LoggerFactory;
   import com.alibaba.dubbo.common.serialize.kryo.utils.ReflectionUtils;
   
   import com.esotericsoftware.kryo.Kryo;
   import com.esotericsoftware.kryo.Serializer;
   import com.esotericsoftware.kryo.serializers.JavaSerializer;
   
   public class CompatibleKryo extends Kryo {
   
       private static final Logger logger = LoggerFactory.getLogger(CompatibleKryo.class);
   
       @Override
       public Serializer getDefaultSerializer(Class type) {
           if (type == null) {
               throw new IllegalArgumentException("type cannot be null.");
           }
   
           if (!type.isArray() && !type.isEnum() && !ReflectionUtils.checkZeroArgConstructor(type)) {
               if (logger.isWarnEnabled()) {
                   logger.warn(type + " has no zero-arg constructor and this will affect the serialization performance");
               }
               return new JavaSerializer();
           }
           return super.getDefaultSerializer(type);
       }
   }
   ```
