返回的默认为resource/templetes下的html或jsp文件
1.Control包中的类如果加入的注解为@Controller
「使用@Controller注解，在对应方法上视图解析切可以解析return的jsp\html页面，并且跳转到相对应的页面」
@Controller
public class UnitConntrol {
@Autowired
UnitService unitService;
@RequestMapping(value = "/findUintId/{id}",method = RequestMethod.GET)
public Object findUnitId(@PathVariable("id") Integer id, Model model){
System.out.println("jinru");
Unit unit = unitService.selectByPrimaryKey(id);
System.out.println(unit.getName());
model.addAttribute(unit);
return "unitview";
}
/**
——第二种方法---
@RequestMapping(value = "/findUintId/{id}",method = RequestMethod.GET)
public @ResponseBody ModelAndView findUnitId(@PathVariable("id") Integer id, Model model){
System.out.println("jinru");
Unit unit = unitService.selectByPrimaryKey(id);
System.out.println(unit.getName());
model.addAttribute(unit);
return new ModelAndView("unitview.html");
}
*/
}
2.Control包中的类如果加入的注解为@RestController{RestController = ResponseBody + Controller}
方法return无法返回jsp/html页面，配置的视图解析器 InternalResourceViewResolver不起作用，返回的内容就是Return里的内容。
@RestController
public class UserControl {
@Autowired
UserService userService;
//根据ID对user查看
@RequestMapping(value = "/findByUserid/{id}",method = RequestMethod.GET)
public ModelAndView findByUserid(@PathVariable("id")Integer id, Model model){
System.out.println(“running findByUserid");
User user = userService.findByUserid(id);
System.out.println(user.getName());
model.addAttribute("user",user);
return new ModelAndView("userview.html");
}
}
