[MyBatis] 如何让MyBatis支持代码级事务处理

MyBatis提供的sqlSession对象是可以用来帮助我们实现事务处理的，方式和JDBC的类似，具体请见代码：

import java.sql.Connection;
import java.sql.SQLException;
import java.text.Format;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import org.apache.ibatis.session.SqlSession;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import jp.co.rakuten.rtms.batch.common.exception.BatchApplicationException;

/**
 * To verify the possibility of commit/rollback after a part of code

        long startTime = System.currentTimeMillis(); 

        try {
            logger.info("isAutoCommit="+session.getConnection().getAutoCommit());

            Connection conn = session.getConnection();
            conn.setAutoCommit(false);

            
            try {
