>[info]BaseService支持使用transaction方法实现在回调接口中使用事务操作，如下： ``` public void t12() { BaseService service = Application.getService("demo"); service.transaction(new TransactionSql() { @Override public void doTranSql() { service.setData(123,"aaaa","bbbbb").insert("i","s","t"); service.where("id", 3).delete(); service.where("id", 5).setData(134,"0123456789012345678901234超过30长度","b2").update("i","s","t"); } }); if(null==service.getError()) { System.out.println("事务执行成功"); }else { System.out.println("事务执行失败，事务回滚"); } } ```
