1、需要jar包：
gradle引入：
compile group: 'com.belerweb', name: 'pinyin4j', version: '2.5.1'
搜索jar包网址：http://mvnrepository.com
2、代码：

3、批量插入语句：
<!-- 批量导入 --> <insert id="batchInsert" parameterType="java.util.List" > insert into t_hro_xxx( uuid, parent_id, code, name, order_num, corp_id, creator, updater, create_time, modify_time, first_letter, full_pinyin) values <foreach collection="list" item="item" index="index" separator="," > ( #{item.uuid,jdbcType=BIGINT}, #{item.parentId,jdbcType=BIGINT}, #{item.code,jdbcType=VARCHAR}, #{item.name,jdbcType=VARCHAR}, #{item.orderNum,jdbcType=INTEGER}, #{item.corpId,jdbcType=BIGINT}, #{item.creator,jdbcType=BIGINT}, #{item.updater,jdbcType=BIGINT}, #{item.createTime,jdbcType=VARCHAR}, #{item.modifyTime,jdbcType=VARCHAR}, #{item.firstLetter,jdbcType=VARCHAR}, #{item.fullPinyin,jdbcType=VARCHAR} ) </foreach> </insert>
4、打印语句：
