controller代码：

@Controller("/fruit")

public class FruitsController {

@Autowired

private FruitsService fruitsService;

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

@ResponseBody

public String showfruit(HttpServletRequest request){

System.out.println("==================--------------");

Map<String,Object> result = new HashMap<String,Object>();

result.put("success", false);

Map<String, String[]> map = request.getParameterMap();

Object oid = map.get("id");

if(oid!=null){

int id = Integer.parseInt(((String[]) oid)[0]);

Fruits fruit = fruitsService.getFruitById(id);

System.out.println(fruit);

result.put("success", true);

result.put("fruit", fruit);

}

return "showfruit";

}

}

访问路径：

localhost:端口号//项目名/fruit/showfruit?id=1

运行结果：

404 

[org.springframework.web.servlet.PageNotFound] - No mapping found for HTTP request with URI [/fruitStore/fruit/showfruit] in DispatcherServlet with name 'SpringMVC'

Answer 1

@Controller  @RequestMapping("/fruit") ?

Answer 2

如下：@Controller @RequestMapping("/fruit") public class FruitsController {     ... }
