Java Hibernate:MySQLSyntaxErrorException:未知列'；在'；字段列表'；

我刚开始冬眠

我想从事务表中获取所有记录

我犯了以下错误

 Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column transactio2_.deleted' in 'field list'

虽然表中存在

已删除
列

实体类：

@Entity
@Table(name = "transaction")
public class Transaction implements Comparable<Transaction>
{
@Id
@GeneratedValue
@Column(name = "transactionId")
private int transactionId;

@Column(name = "date")
private Date date;

@Column(name = "amount")
private BigDecimal amount;

@ManyToOne
@JoinColumn(name = "transactionTypeId")
private TransactionType transactionType;

@ManyToOne
@JoinColumn(name = "userId")
private User user;

@Column(name = "operation")
private String operation;

@Column(name = "lastUpdate")
private Date lastUpdate;

@Column(name = "deleted")
private int deleted;

@Column(name = "remark")
private String remark;

public Transaction()

    super();

    {
        return 1;

    return 0;

public Date getLastUpdate()
{
    return lastUpdate;

public void setLastUpdate(Date lastUpdate)

@ManagedBean
@ViewScoped
public class TransactionBean implements Serializable
{

    ArrayList<Transaction> transactionList = new ArrayList<>();

    /**
   * Public Constructor
    */
public TransactionBean()
{
     Session session = HibernateUtil.getSessionFactory().openSession();
    @SuppressWarnings("unchecked")
    transactionList = (ArrayList<Transaction>) session.createCriteria(Transaction.class).list();     
}

您正在
tinyint
列中使用0或1，使用下面的映射它将起作用。

@Column(name = "deleted")
private boolean deleted;

如果你需要尝试的话，还有一个改变，
您使用的是布尔值
0,1
，因此可以使用
tinyint（1）
，这对于0,1来说已经足够了。

您可以找到有关hibernate映射的更多信息
如果我手动创建JPA实体，我会遇到同样的问题。
只需确保每个getter函数都有@Column注释

@Column(name = "deleted")
public int getDeleted()
{
    return deleted;
}

我最近也遇到过类似的问题。在我的例子中，缺少数据库列
请添加表创建脚本，以使用hibernate Mapping验证db列名，可能是您在db中拼写了错误的列名，首先检查将
deleted
列数据类型从
tinyint
更改为
int
与
transactionId
列相同，并解决您的问题我使用tinyint是因为我要设置值，仅为零（0）或一（1），然后在映射中尝试
boolean
。如果只需要删除@Column（name=“deleted”）private int的0或1，只需再更改一次
tinyint（1）
；映射和tinyint（4），当我插入数据时，数据被很好地插入到“TransactionType”（在“Transaction”实体中，它在插入时不会给出任何错误）中，我错过了删除列。这就是为什么它会给出错误，但Hibernate会给出错误“未知列transactio2”。删除“在“字段列表”中”，这就是为什么我感到困惑的原因，它应该给出类似“未知列”TarnActionType。删除“在“字段列表”中”的错误@JubinPetel:thanx供您参考
@Column(name = "deleted")
public int getDeleted()
{
    return deleted;
}
