一.首先奉上项目目录结构：
说明： dao,mapping,model包下的所有内容可以使用Generator工具自助生成。
具体用法，可以网上学习一下，比较简单，主要做以下工作：
１.提供相关的数据库的jar包及数据库连接配置
２.提供实体类与表映射关系
３.提供一个生成代码的空目录。
４.执行一条执行语句
进入到generator的目录下，shift右键选择 在此处打开命令窗口。
执行 java -jar mybatis-generator-core-1.3.2.jar -configfile generator.xml -overwrite
二.核心配置文件spring.xml, spring-mybatis.xml,spring-mvc.xml 具体源码
１.spring.xml 源码：

五. 核心控制器部分代码：
@Controller
@RequestMapping("userController")
public class UserController {
private static final Logger logger = Logger.getLogger(UserController.class);
@Autowired
public UrUserServiceI uruserService;
@RequestMapping("/login")
public String handleLogin(String username,String password,HttpServletRequest request){
logger.info(username+","+password);
String adminUser=ConfigUtils.getValue("admin");
String adminPwd=ConfigUtils.getValue("pwd");
if(username==null|password==null|username==""|password==""){
request.setAttribute("loginError", "用户名密码不能为空");
return "login";
}else if(adminUser.equals(username.trim())&&adminPwd.equals(password.trim())){
request.getSession().setAttribute("user", username);
return "redirect:/userController/showUsers.do";
}else{
request.setAttribute("loginError", "用户名密码有误");
return "login";
}
}
}
