nutz版本：nutz-1.r.60
问题描述：
在Setup中存在如下代码

Daos.createTablesInPackage(dao, "com.kerbores", false);// 创建表 line99
Daos.createTablesInPackage(dao, "com.melo", false);// 创建表 line100
Daos.migration(dao, "com.kerbores", true, true, true);// 更改表 line101
Daos.migration(dao, "com.melo", true, true, true);// 更改表 line102

实体类代码如下：

@Table("h_notice_user_sync_record")
@Comment("站内通知同步记录")
@TableMeta("{'mysql-charset':'utf8mb4'}")
@TableIndexes(@Index(fields = {"user_id", "user_type"}, name = "h_notice_user_sync_record.unique_idx"))
public class NoticeUserSyncRecord extends Entity {

    @Column("user_id")
    @Comment("用户Id")
    @ColDefine(notNull = true)
    private int userId;

    @Comment("用户类型")
    @Column("user_type")
    @ColDefine(notNull = true)
    private User.Type userType;

    @Comment("通知Id")
    @Column("notice_id")
    private int noticeId;

    @Column("sync_time")
    @Comment("最后同步时间")
    private Date syncTime;
}

Entity中有个自增主键id
当实体类没有@TableIndexes这一行注解且数据库无表h_notice_user_sync_record时，可以成功创建表
当增加@TableIndexes注解后，
1.当数据库无表h_notice_user_sync_record时，出现以下报错

从报错内容来看是Table 'h_notice_user_sync_record' doesn't exist!导致的
2.如果表存在，不会创建索引
希望解答：
是否使用方式不正确？如果是，正确使用方式应该如何写？
如果是nutz版本问题，由于项目原因无法更新，就采用手工建索引方式解决

2 回复

索引名不要写 表名.xx

顶多写个 yyy_xxx ，不要包含点号
