Spring Hibernate“映射数据类型”；字节"；枚举属性转换器不工作-错误：没有JDBC类型的方言映射：277630005

使用spring启动版本：2.2.6.RELEASE |数据库：SQLServer2008 | org.hibernate.dialent.SQLServer2008dialent

使用转换器映射java中引用“Byte”的“TINYINT”类型列的枚举时，出现以下错误：

当对初始数据库休眠ddl时，JDBC类型277630005没有方言映射

但是，当在不使用枚举的情况下作为字节进行直接映射时，它可以正常工作

转换器：

@Converter
public class CharacterClassConverter implements AttributeConverter<CharacterClassIndicator, Byte> {
    @Override
    public Byte convertToDatabaseColumn(CharacterClassIndicator characterClassIndicator) {
        return characterClassIndicator != null ? characterClassIndicator.getCode() : null;
    }

    @Override
    public CharacterClassIndicator convertToEntityAttribute(Byte code) {
        return Stream.of(CharacterClassIndicator.values())
                .filter(value -> value.getCode().equals(code))
                .findFirst()
                .orElseThrow(UnsupportedOperationException::new);
    }
}

实体代码：

@Entity
@Table(name = "Character")
public class Character {
    @Id
    @Column(name = "AccountID")
    private String id;

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

    @Column(name = "Class")
    @Convert(converter = CharacterClassConverter.class) // if remove this line and change type to Byte, works correctly
    private CharacterClassIndicator characterClass;

    @Column(name = "cLevel")
    private Integer level;

    @Column(name = "Strength")
    private Short strenght;

    @Column(name = "Dexterity")
    private Short dexterity;

    @Column(name = "Vitality")
    private Short vitality;

    @Column(name = "Energy")
    private Short energy;

    @Column(name = "Resets")
    private Integer resets;

    .... gets and setters
}

有人知道如何解决吗？

使用

columnDefinition

@Column(name = "Class", columnDefinition = "TINYINT") 

---

数据库中的

TINYINT

的大小是多少？这是TINYINT（4）谢谢Eklavya，它是这样工作的。

@Column(name = "Class", columnDefinition = "TINYINT")
