Control的方法中return不跳转页面

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");
    }
}
