mybatis 批量新增 插入 案例

XML配置如下 ElementDefineMapper.xml
  

 <insert id="batchInsert" parameterType="java.util.List" >    insert into AM_ELEMENT_DEFINE (ELEMENT_ID, ELEMENT_NAME, TYPE_ID, CATEGORY_ID)      <foreach collection="list" item="item" index="index" separator="union all">    select #{item.elementId,jdbcType=VARCHAR}, #{item.elementName,jdbcType=VARCHAR},    #{item.typeId,jdbcType=VARCHAR}, #{item.categoryId,jdbcType=VARCHAR}      from dual      </foreach>  </insert>

      
ElementDefineMapper dao层如下
 
void batchInsert(@Param('list') List inerstList);
 
如此这般即可
