java中的批量导入，批量更新数据

批量插入 数据，提高效率

Dao层

int insertBatch(List<HealthImport> list);

xml文件

<insert id="insertBatch" parameterType="java.util.List" >
    insert into health_import
    (answer_id, sample_num, `name`,
    sex, age, select_goal,
    pro_id, pro_name, select_result,
    sample, patient_id, barcode,
    reviewer, idcard, refer_range,
    unit, create_time, `result`,
    flag, message)
    values
    <foreach collection="list" index="index" item="monitor" separator=",">
      (#{monitor.answerId,jdbcType=INTEGER}, #{monitor.sampleNum,jdbcType=VARCHAR}, #{monitor.name,jdbcType=VARCHAR},
      #{monitor.sex,jdbcType=VARCHAR}, #{monitor.age,jdbcType=VARCHAR}, #{monitor.selectGoal,jdbcType=VARCHAR},
      #{monitor.proId,jdbcType=VARCHAR}, #{monitor.proName,jdbcType=VARCHAR}, #{monitor.selectResult,jdbcType=VARCHAR},
      #{monitor.sample,jdbcType=VARCHAR}, #{monitor.patientId,jdbcType=VARCHAR}, #{monitor.barcode,jdbcType=VARCHAR},
      #{monitor.reviewer,jdbcType=VARCHAR}, #{monitor.idcard,jdbcType=VARCHAR}, #{monitor.referRange,jdbcType=VARCHAR},
      #{monitor.unit,jdbcType=VARCHAR}, #{monitor.createTime,jdbcType=TIMESTAMP}, #{monitor.result,jdbcType=INTEGER},
      #{monitor.flag,jdbcType=INTEGER}, #{monitor.message,jdbcType=VARCHAR})
    </foreach>
  </insert>

批量 更新数据 提高效率

Dao层

int updateBatch(List<HealthImport> list);

xml文件
