我不确定如何修复以下异常。我的数据源被注入(inject)到 sessionfactory 中并由 DAO 使用来创建查询。考虑到应用程序的其他模块运行良好，我的数据库运行良好。这让我怀疑我的模型类“购物”在某种程度上是错误的。使用 java.sql.blob 是在 mysql 数据库中表示长 blob 的错误方法吗？

模型类:
@Entity
@Table(name="shopping")
public class Shopping implements java.io.Serializable {
private static final long serialVersionUID = 1L;
@Id
@Column(name="Name", unique=true, nullable=false, length=50)
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Column(name="Price", nullable=false, length=50)
public String getPrice() {
return price;
}
public void setPrice(String price) {
this.price = price;
}
@Temporal(TemporalType.DATE)
@Column(name="Date1", nullable=false)
public Date getDate1() {
return date1;
}
public void setDate1(Date date1) {
this.date1 = date1;
}
@Temporal(TemporalType.DATE)
@Column(name="Date2", nullable=false)
public Date getDate2() {
return date2;
}
public void setDate2(Date date2) {
this.date2 = date2;
}
private String name;
private String price;
private Date date1;
private Date date2;
private Blob image;
@Column(name="Image", nullable=false)
public Blob getImage() {
return image;
}
public void setImage(Blob image) {
this.image = image;
}
}
DAO方法:
public List<Shopping> getShopping() {
Session session = sessionFactory.openSession();
List<Shopping> list = session.createCriteria(Shopping.class).list();
session.close();
return list;
}

我非常感谢任何帮助
最佳答案
原来错误是由 mySQL 表中的错误日期引起的，我没有正确格式化日期。
关于java - org.hibernate.exception.GenericJDBCException : could not execute query] with root cause，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/42558157/
