------解决方法--------------------------------------------------------
你的实体类有没有实现serializable接口?
  对象序列化出错
  比如
  public class BaseBusinessClass implements Serializable{
  private String id;
  private String name;
 
  public String getId(){

return id;
  }
  public void setId(String id){
  this.id=id;
  }
  public String getName(){
  return name;
  }
  .....
------解决方法--------------------------------------------------------
could not deserialize,不能反序列化，你看看你的hibernate配置中是否有序列化类型数据，即SerializableType，与对应的数据库数据是否相同，（数据库对应blob型），还有你是否有换过jdk，不同的jdk序列化的时候得到的结果是不同的，如果保存数据的时候用的是一个版本的jdk，而读数据（即反序列化的时候）是另一个版本的jdk那么有可能反序列化不成功。
