解釋壹下:
這段代碼我記得是看了spring源碼後自己寫的。
1、getBean("transactionManager");是獲得spring中事務管理器那個bean,妳自己改名字。
2、把這段代碼放到妳的BaseAction中:
protected Object beginTransaction(ITransactionManager transactionManagerImpl){
DataSourceTransactionUtil dt = new DataSourceTransactionUtil();
return dt.execute(transactionManagerImpl);
}
3.在妳需要開啟事務的action中調用beginTransaction方法transactionManagerImpl這個對象妳寫個匿名內部類然後實現doInTransaction() 方法,在doInTransaction() 中去寫妳調用多個service的代碼
