越来越多的企业开始选择springmvc+mybatis来构建系统架构，在电商热门的今天，springmvc+mybatis已成为电商项目架构的最佳搭配。Spring mvc和struts2都属于表现层的框架，spring mvc是Spring框架的一部分，较于struts2框架使用的更加广泛;mybatis和hibernate都属于持久层的框架，mybatis是对jdbc操作数据库的的过程进行封装，使开发者只需要关注 SQL 本身，而不需要花费精力去处理例如注册驱动、创建connection、创建statement、手动设置参数、结果集检索等jdbc繁杂的过程代码。

算法是指完成一个任务所需要的具体步骤和方法。也就是说给定初始状态或输入数据，经过计算机程序的有限次运算，能够得出所要求或期望的终止状态或输出数据。算法常常含有重复的步骤和一些比较或逻辑判断。如果一个算法有缺陷，或不适合于某个问题，执行这个算法将不会解决这个问题。不同的算法可能用不同的时间、空间或效率来完成同样的任务。一个算法的优劣可以用空间复杂度与时间复杂度来衡量。 -Algorithm is required to complete a task specific steps and methods. That is a given initial state or input data through a computer program for a limited time operations, able to draw the required or desired end state or output data. Algorithm often contain repeat the steps and some of the more or logical judgments. If an algorithm is defective, or not suitable for a particular problem, the implementation of this algorithm will not solve the problem. Different algorithms may use a different time, space or efficiency to accomplish the same task. Pros and cons of an algorithm can use space complexity and time complexity of the evaluation.

现象为蜂鸣器频率的鸣响四个拨码开关，拨上去对应的前四个LED灯亮，体现了pld io功能的灵活。请把拨码开关右上方的跳线帽跳上，同时拔掉ADC0804的跳线帽。-Phenomenon for the buzzer frequency ringing four DIP switches, dial up the corresponding first four LED lights, reflect the function of flexible pld io. Please dial code switch at the top right of the jumper cap jumped, and pulled out the jumper cap ADC0804.

实现方法: 用MFC的程序向导生成一个常规DLL,在常规DLL内有一派生自CWinApp的实例,再用MFC的程序向导生成一个MFC EXE应用程序,把MFC EXE应用程序中 CAppView,CMainFrame,CAppDocument的文挡和RES目录下的资源拷贝到常规DLL项目中,添加到项目中,编译生成一DLL,在另外一个WIN32应用程序中,启动一线程,在线程函数中显式装载该DLL,取的该DLL内的当前线程, CWinThread *pThread=GetCurrentThread() pThread->Run() 就可装载启动常规DLL内应用程序框架.-method: a normal DLL file has been created with the program wizard and there is an instance generated from CWinApp in the DLL file.Create another MFC EXE appliaction and copy CAppView,CMainFram,CAppDocument and the resources in RES directory to the normal DLL and add to the projec and compile and generate a DLL. In a Win32 application, start a thread which loads the DLL with codes, get the running thread, ie.CWinThread*pThread=GetCurrentThread(), then,pThread->Run() executes the loading and start the execution of the application framework in the normal DLL file.
