我正在从hibernate 4.2.5.Final升级到4.3.6.Final,4.3.6 hibernate libs导致mysql未知的列类型异常.以下课程已经简化,因为我无法完整地展示我公司的生产代码.

@Entity
@Table(name = "area")
public class Area {
    private Integer id;
    private Map<BasicType, BasicConfiguration> configurationsMap =
        new HashMap<BasicType, BasicConfiguration>();

    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    public Integer getId() {
        return id;

    public void setId(Integer id) {

    }

    @OneToMany(fetch = FetchType.EAGER, cascade = {CascadeType.ALL}, orphanRemoval = true)
    @JoinTable(name = "area_configuration", joinColumns = {@JoinColumn(name = "area_id")},
               inverseJoinColumns = {@JoinColumn(name = "basic_configuration_id")})
    @MapKeyEnumerated(EnumType.STRING)
    @MapKeyColumn(name = "type")
    public Map<BasicType, BasicConfiguration> getConfigurationsMap () {
        return configurationsMap;
    }

BasicType只是一个枚举
