ibatis 对事务和批量提交的处理，以及回滚的处理

//ibatis batch 示例

    protected void batchCreate(final List<T> memberList, final String statement) {
        
        SqlMapClientCallback callback = new SqlMapClientCallback() {
            public Object doInSqlMapClient(SqlMapExecutor executor) throws SQLException {    
                executor.startBatch();
                for (T tObject : memberList) {               
                    executor.insert(statement, tObject); // statement在*MapSql.xml一条语句的id    
                }            
                executor.executeBatch();           
                return null;
                
            }
            
        };
        
如果有很多非查询的（insert/update/delete）语句要处理，为了减少网络通讯的流量，可以进行批处理
sqlMap.startBatch();
  insert/update/delete 语句处理
sqlMap.endBatch();

try {

      sqlMapClient.startTransaction(); //事务开始
      Person p = 

       (Person)sqlMapClient.queryForObject

                       ("getPerson", new Integer(9));

      p.setLastName("Smith");

      sqlMapClient.update("updatePerson", p);

      Department d = 

       (Department)sqlMapClient.queryForObject       

                       ("getDept", new Integer(3));

      p.setDepartment(d);

      sqlMapClient.update("updatePersonDept", p);

      sqlMapClient.commitTransaction(); //提交事务，从开始到这里是一个事务


} finally {

        sqlMapClient.endTransaction(); //事务结束
}

//回滚

sqlMap.getCurrentConnection().rolback();

即可。
