我对 Spring MVC 很陌生。我正在创建一个应用程序，并且我想使用 xml 配置（因为它对我来说更容易理解和学习），但是我想使用注释配置有一些好处。
我有一个在 xml 配置中运行良好的应用程序，所以我只想将我的 MVC 控制器转换为注释，并仍然维护我的其余 xml 配置。基本上我想要的是使用 @Controller 注释，因为 SimpleFormController 已被弃用。我在这个论坛上关注了以前的主题，但我收到了HTTP 404 错误。有人可以在这里帮助我或告诉我我做错了什么吗？
控制器
import java.util.HashMap;
import java.util.Map;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.log4j.Logger;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.bind.annotation.RequestMethod;
import com.crimetrack.service.CountryManager;
@Controller
@RequestMapping(value="/hello.htm", method = RequestMethod.GET)
public class CountryListController{
private final Logger logger = Logger.getLogger(getClass());
private CountryManager countryManager;
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception {
logger.debug("In Http method for CountryListController");
Map<String, Object> myModel = new HashMap<String, Object>();
myModel.put("countryList", this.countryManager.getCountries());
return new ModelAndView("hello", "model", myModel);
}
public void setCountryManager(CountryManager countrymanager){
this.countryManager = countrymanager;
}
}
