ibatis batch import mysql database

Need to batch import excel data into mysql database at work

The amount of excel data is relatively large, about 10,000 items are imported at a time

Using the traditional for loop to import the mysql database is very time-consuming, about 3 minutes

All need to use batch processing, the core algorithm is as follows

/**
		* Bulk insert function
		*/
	   @SuppressWarnings("unchecked")
	   public void insertBatch(final List<WinddataBo> list) {
		   SqlMapClient sqlMapClientTemplate = baseDao.getSqlMapClient();
		   try {
			   sqlMapClientTemplate.startTransaction();//Start transaction
			   /**Transaction todo start***/
			   /**First execute delete all**/
			   sqlMapClientTemplate.delete("com.zero2ipo.ylcf.winddata.deleteAll");
			   sqlMapClientTemplate.insert("com.zero2ipo.ylcf.winddata.insertBatch",list);
			   /**Transaction todo end***/
			   sqlMapClientTemplate.commitTransaction();//Commit the transaction
		   } catch (SQLException e) {
			   e.printStackTrace ();
		   }finally {
			   try {
				   sqlMapClientTemplate.endTransaction();//The transaction is completed
			   } catch (SQLException e) {
				   try {
					   sqlMapClientTemplate.getCurrentConnection().rollback(); //Transaction rollback
				   } catch (SQLException e1) {
					   e1.printStackTrace();
				   }
				   e.printStackTrace ();
			   }
		   }

	   }

   The ibatis sql file is as follows

<!--Batch Insert-->
<insert  id ="com.zero2ipo.ylcf.winddata.insertBatch"  parameterClass ="java.util.List">
   <![CDATA[
        insert into winddata(CRETE_DATE , SHOUPANJIA , COLUMN1,COLUMN2 ) values
    ]]>
	<iterate  conjunction ="," >
	<![CDATA[
            (#list[].creteDate#,#list[].shoupanjia#,#list[].column1#,#list[].column2#)
        ]]>
	</iterate >
</insert >

 

   

   It takes about 3 seconds to import more than 10,000 pieces of data into excel at a time
