一：概述
SSM框架在项目开发中经常使用到，相比于SSH框架，它在仅几年的开发中运用的更加广泛。

  • Spring作为一个轻量级的框架，有很多的拓展功能，最主要的我们一般项目使用的就是IOC和AOP。
  • SpringMVC是Spring实现的一个Web层，相当于Struts的框架，但是比Struts更加灵活和强大！
  • Mybatis是 一个持久层的框架，在使用上相比Hibernate更加灵活，可以控制sql的编写，使用 XML或注解进行相关的配置！

根据上面的描述，学习SSM框架就非常的重要了！

二：搭建一个SSM的过程

然后直接配置 pom.xml文件中的包依赖！

7：编写Controller，和对应得业务界面
新增UserController ，通过参数传递uid获取用户，若用户存在，跳转到showName.jsp ，若用户不存在，则跳转到error.jsp,并返回提示信息！

 

  1. package org.ssm.dufy.web;

  2.  

  3. import javax.servlet.http.HttpServletRequest;

  4.  

  5. import org.springframework.beans.factory.annotation.Autowired;

  6. import org.springframework.stereotype.Controller;

  7. import org.springframework.ui.Model;

  8. import org.springframework.web.bind.annotation.RequestMapping;

  9. import org.springframework.web.bind.annotation.RequestMethod;

  10. import org.springframework.web.bind.annotation.RequestParam;

  11. import org.springframework.web.servlet.ModelAndView;

  12. import org.ssm.dufy.entity.User;

  13. import org.ssm.dufy.service.IUserService;

  14.  

  15. @Controller

  16. public class UserController {

  17.  

  18. @Autowired

  19. private IUserService userService;

  20.  

  21. @RequestMapping(value="/showname",method=RequestMethod.GET)

  22. public String showUserName(@RequestParam("uid") int uid,HttpServletRequest request,Model model){

  23. System.out.println("showname");

  24. User user = userService.getUserById(uid);

  25. if(user != null){

  26. request.setAttribute("name", user.getUserName());

  27. model.addAttribute("mame", user.getUserName());

  28. return "showName";

  29. }

  30. request.setAttribute("error", "没有找到该用户！");

  31. return "error";

  32. }

  33. }
