服务启动model生成表异常

model生成新表异常，字段没有DEFAULT NULL 了，以前是好的，是不是最近两天官网改过这个生成逻辑？

@Table("mv_conflict")
public class Mv_conflict extends Model implements Serializable {
    private static final long serialVersionUID = 1L;

    @Column
    @Id
    @Comment("ID")
    private int id;

    @Column
    @Comment("冲突关键词")
    @ColDefine(type = ColType.VARCHAR, width = 50)
    private String key;

    @Column
    @Comment("状态：1:未处理，2:已处理")
    private int status;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getKey() {
        return key;
    }

    public void setKey(String key) {
        this.key = key;
    }

    public int getStatus() {
        return status;
    }

    public void setStatus(int status) {
        this.status = status;
    }
}
