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
