我们都知道Mybatis在插入单条数据的时候有两种方式返回自增主键:
1、对于支持生成自增主键的数据库:useGenerateKeys和keyProperty。
2、不支持生成自增主键的数据库:<selectKey>。
但是怎对批量插入数据返回自增主键的解决方式网上看到的还是比较少,至少百度的结果比较少。
Mybatis官网资料提供如下:
First, if your database supports auto-generated key fields (e.g. MySQL and SQL Server), then you can simply set useGeneratedKeys="true" and set the keyProperty to the target property and you're done. For example, if the Authortable above had used an auto-generated column type for the id, the statement would be modified as follows:
<insert id="insertAuthor" useGeneratedKeys="true"
keyProperty="id">
insert into Author (username,password,email,bio)
values (#{username},#{password},#{email},#{bio})
</insert>
id
