搭建好 SsM 集成框架，Hellocontroller 的编写就变得非常简单

@Controller
public class HelloController {
/**
* 注入 service 层 userService 接口
*/
@Autowired
private UserService userService;
@RequestMapping(“/hello”)
public ModelAndView hello(){
ModelAndView mv=new ModelAndView();
/**
* 调用 service 层查询方法
*/
User user=userService.queryUserById(7);
System.out.println(user);
mv.addObject(“user”, user);
mv.setViewName(“hello”);
return mv;
}
}

视图页面局部代码接管结果显示:

<body>
欢送你，${user.userName}
</body>

启动 jetty 服务器，拜访地址: http://localhost:8080/ssM/hello.do
