关于ibatis批量操作的代码

Mysql数据库，批量入库操作
使用ibatis批处理
代码如下：
public int addMessages(List list) {
    int result = 0;
    try {
        //this.getSqlMapTransactionManager().startTransaction();
        this.startBatch();
        for(int i=0;i<list.size();i++) {
  this.insert("addMessage",(Message)list.get(i));
        }
        this.executeBatch();
//this.getSqlMapTransactionManager().commitTransaction();
result = 1;
} catch (Exception e) {
   result = 0;
   e.printStackTrace();
} finally {
   try {
//this.getSqlMapTransactionManager().endTransaction();
    } catch (Exception e) {
e.printStackTrace();
    }
return result;
   }
}


我将事务管理的代码注掉了是没有错误的，但是不能实现事务管理。
我加的事务代码是会报错的，希望各位大侠指点谜经。我在这里先谢谢了！

加上我的事务管理代码报如下错误：

晕，可我没找到那里开始事务了啊。
我发现ibatis的batch自动提交了每次的数据库操作，所以当操作发生异常时，怎么样能实现事务的回滚，我自己加的事务又不能执行，郁闷。帖子还被评为新手贴，更打击人了。是啊自己刚用ibatis，不够强啊。
那为大侠对ibatis的batch比较熟，同事又能进行事务管理，请多指点。
小弟不盛感激！！！！
  

最后补充一句，我是用的mysql数据库。

TransactionManager could not start a new transaction. A transaction is already started.

提示信息已经很明显了，请检查事务已经在什么别的地方开启？

我想问一下Mysql数据库的事务管理怎么实现，谢谢！
