mybatis实现批量插入并返回主键(xml和注解两种方法)

void batchInsertCameras(@Param("list") List<Camera> cameras);

<insert id="batchInsertCameras" useGeneratedKeys="true" keyProperty="cameraNo">
    insert into camera (chanIndex,cameraName)
    values
    <foreach collection="list" item="c" separator=",">
        (#{c.chanIndex},#{c.cameraName})
    </foreach>
</insert>

@Insert("<script>insert into camera (chanIndex,cameraName) values " +
        "<foreach collection='list' item='c' separator=','>(#{c.chanIndex},#{c.cameraName})</foreach></script>")
@Options(useGeneratedKeys = true, keyProperty = "cameraNo")
void batchInsertCameras(@Param("list") List<Camera> cameras);

cameraMapper.batchInsertCameras(cameras);
for(Camera camera : cameras){
    System.out.println(camera.getCameraNo());
}

int insertBatchUserReturnId(List<User> users);

<insert id="insertBatchUserReturnId" keyProperty="userId" useGeneratedKeys="true">
 insert into message (user_id, user_name, user_type, user_passwd, user_phone,user_pic,user_address)
 values
 <foreach collection="list" item="item" open="(" close=")" separator=",">
  #{item.userId,jdbcType=INTEGER}, #{item.userName,jdbcType=VARCHAR}, #{item.userType,jdbcType=TINYINT}, 
  #{item.userPasswd,jdbcType=VARCHAR}, #{item.userPhone,jdbcType=VARCHAR},
  #{item.userPic,jdbcType=VARCHAR},#{item.userAddress,jdbcType=VARCHAR}
 </foreach>
</insert>
