MyBatis-spring和spring JDBC批量插入Mysql的效率比较

工具框架用spring-batch，数据库是mysql（未做特殊优化）。

比较数据框架mybatis和spring jdbc的插入效率。

 

Mybatis三种实现：

1、mybatis的官方写法

public void batchInsert1(List<Poi> poilist) throws Exception {SqlSession sqlSession = sqlSessionFactory.getObject().openSession(ExecutorType.BATCH);PoiMapper pmapper = sqlSession.getMapper(PoiMapper.class);try {for (Poi poi : poilist) {pmapper.insertPoi(poi);}sqlSession.commit();} finally {sqlSession.close();}}

 其中Poi是一个bean。

 PoiMapper定义：

public interface PoiMapper {@Insert("insert into tb_poi (tag, poi, poiid, meshid, owner, featcode, sortcode, namec, namee, namep, names) values (#{tag}, GeomFromText(#{point}), #{poiid}, #{meshid}, #{owner}, #{featcode}, #{sortcode}, #{namec}, #{namee}, #{namep}, #{names}) ")public void insertPoi(Poi poi);}

2、利用mysql特性，拼写insert sql。

public void batchInsert2(List<Poi> poilist) throws Exception {SqlSession sqlSession = sqlSessionFactory.getObject().openSession(ExecutorType.BATCH);try {sqlSession.insert("com.emg.trans.mapper.batchMapper.batchInsert", poilist);sqlSession.commit();} finally {sqlSession.close();}}

“com.emg.trans.mapper.batchMapper.batchInsert”在mybatis的xml中定义的sql，定义如下：

<mapper namespace="com.emg.trans.mapper.batchMapper">  <insert id="batchInsert" parameterType="List">    insert into tb_poi (tag, poi, poiid, meshid, owner, featcode, sortcode, namec, namee, namep, names) values    <foreach collection="list" item="poi" index="index" separator="," >         (#{poi.tag}, GeomFromText(#{poi.point}), #{poi.poiid}, #{poi.meshid}, #{poi.owner}, #{poi.featcode}, #{poi.sortcode}, #{poi.namec}, #{poi.namee}, #{poi.namep}, #{poi.names})    </foreach>  </insert></mapper>

3、利用spring的事务，直接执行插入操作。

@Transactional("dbTransaction")public void batchInsert3(List<Poi> poilist) throws Exception {for (Poi poi : poilist) {apmapper.insertPoi(poi);}}

 apmapper是PoiMapper的实例，用@Autowired配置。

Spring-JDBC的三种实现：

A、用spring事务执行插入操作

@Transactional("dbTransaction")public void batchInsertJDBC1(List<Poi> poilist) throws DataAccessException {String sql = "insert into tb_poi (tag, poi, poiid, meshid, owner, featcode, sortcode, namec, namee, namep, names) values (?, GeomFromText(?), ?, ?, ?, ?, ?, ?, ?, ?, ?)";for (Poi poi : poilist) {Object[] args = {poi.getTag(), poi.getPoint(), poi.getPoiid(), poi.getMeshid(), poi.getOwner(), poi.getFeatcode(), poi.getSortcode(), poi.getNamec(),poi.getNamee(), poi.getNamep(), poi.getNames()};jdbcTemplate.update(sql, args);}}

B、用spring事务和springjdbc的batchUpdate

@Transactional("dbTransaction")public void batchInsertJDBC2(List<Poi> poilist) throws DataAccessException {String sql = "insert into tb_poi (tag, poi, poiid, meshid, owner, featcode, sortcode, namec, namee, namep, names) values (?, GeomFromText(?), ?, ?, ?, ?, ?, ?, ?, ?, ?)";List<Object[]> batchArgs = new ArrayList<Object[]>();for (Poi poi : poilist) {Object[] args = {poi.getTag(), poi.getPoint(), poi.getPoiid(), poi.getMeshid(), poi.getOwner(), poi.getFeatcode(), poi.getSortcode(), poi.getNamec(),poi.getNamee(), poi.getNamep(), poi.getNames()};batchArgs.add(args);}jdbcTemplate.batchUpdate(sql, batchArgs);}

C、用spring事务，利用mysql特性，拼写insert sql。

@Transactional("dbTransaction")public void batchInsertJDBC3(List<Poi> poilist) throws DataAccessException {StringBuffer sqlbuf = new StringBuffer().append("insert into tb_poi (tag, poi, poiid, meshid, owner, featcode, sortcode, namec, namee, namep, names) values ");MessageFormat form = new MessageFormat("(''{0}'', GeomFromText(''{1}''), ''{2}'', ''{3}'', ''{4}'', ''{5}'', ''{6}'', ''{7}'', ''{8}'', ''{9}'', ''{10}''),");for (Poi poi : poilist) {Object[] args = {poi.getTag(), poi.getPoint(), poi.getPoiid(), poi.getMeshid(), poi.getOwner(), poi.getFeatcode(), poi.getSortcode(), poi.getNamec().replaceAll("'", "\\\\'"),poi.getNamee().replaceAll("'", "\\\\'"), poi.getNamep().replaceAll("'", "\\\\'"), poi.getNames().replaceAll("'", "\\\\'")};sqlbuf.append(form.format(args));}String sql = sqlbuf.toString();sql = sql.substring(0, sql.length()-1);jdbcTemplate.update(sql);}

 

测试一：每次处理100条，共600条。

测试二：每次处理1000条，共9000条。

直接上结论：

mybatis.1最慢。而且慢很多，很多。

mybatis.2很快。是mybatis中最快的。

mybatis.3比2慢一点。

jdbc.A比B稍快，两者差不多，和mybatis.3也在伯仲之间。

jdbc.C最快，比其他5种都快。

大排行，从用时少到用时多：

jdbc.C < mybatis.2 < jdbc.A < jdbc.B , mybatis.3 << mybatis.1
