首先讲一下， 插入一条记录返回主键的 Mybatis 版本要求低点，而批量插入返回带主键的 需要升级到3.3.1版本，3.3.0之前的都不行,
<dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>3.3.1</version> </dependency>
1.MySQL
<insert id="insertByBatch" useGeneratedKeys="true" keyProperty="id" parameterType="java.util.List">
insert into test (sblsh, xh, jsjg,
is_success, is_display, gmt_create,
gmt_modify, create_user)
values
<foreach collection="list" item="item" index="index" separator=",">
(
#{item.sblsh,jdbcType=BIGINT},
#{item.xh,jdbcType=CHAR},
#{item.jsjg,jdbcType=BIGINT},
#{item.isSuccess,jdbcType=TINYINT},
#{item.isDisplay,jdbcType=TINYINT},
SYSDATE(),
SYSDATE(),
#{item.createUser,jdbcType=VARCHAR})
</foreach>
</insert>
单条和多条 使用都是一样的， 加入useGeneratedKeys="true" keyProperty="主键字段"
2.Oracle
<insert id="insertBatch">
<selectKey keyProperty="id" resultType="Long" order="BEFORE">
select test.nextval as id from dual
</selectKey>
insert into test
(id,value,gmt_create,gmt_modified)
select test.nextval, A.* FROM (
<foreach collection="list" item="item" index="index"
separator="union all">
select
#{item.value,jdbcType=VARCHAR},
#{item.gmtCreate,jdbcType=DATE},
#{item.gmtModified,jdbcType=DATE}
from
dual
</foreach>
) A
</insert>
