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。
