Java 从'序列化RestHighLevelClient；org.elasticsearch.client'；

我想从elastic序列化RestHighLevelClient。下面是我的代码

 import org.elasticsearch.client.RestHighLevelClient
 @Component
 public class Client implements Serializable {
  private transient RestHighLevelClient client;
  @PostContruct
  private void init() {
  //code to initialize RestHighLevelClient 
  }
}
private void writeObject(ObjectOutputStream oos) throws Exception {
 oos.defaultWriteObject();
 oos.writeObject(client); 
}
private void readObject(ObjectInputStream ois) throws Exception 
{ 
  ois.defaultReadObject(); 
  client= (RestHighLevelClient)ois.readObject(); 
}

我已经编写了readObject和writeObject进行序列化。但它没有按预期工作。有没有关于如何序列化的线索？

没有建议？没有建议？
