------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。
