错误信息:找不到具有URI[/TestSpringWebApp/hello.htm]的HTTP请求的映射

任何帮助都将不胜感激!

我正在使用注释将请求映射到控制器。控制器代码:

@Controller
@RequestMapping("/hello.htm")
public class HelloController  {    
    protected final Log logger = LogFactory.getLog(getClass());

    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)    
            throws ServletException, IOException {
        String now = (new Date()).toString();

        logger.info("Returning hello view with " + now);

        return new ModelAndView("hello", "now", now);    
    }    
}

Dispatcher-servlet.xml如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans ...>

    <bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping"/>

    <!--
    Most controllers will use the ControllerClassNameHandlerMapping above, but
    for the index controller we are using ParameterizableViewController, so we must
    define an explicit mapping for it.

您必须将@RequestMapping添加到方法,而不是类。如果将它添加到类中,它将作为前缀应用于该类的所有方法映射,但也必须映射该类的方法。

您还需要添加

<mvc:annotation-driven />

发送到Dispatcher-servlet.xml文件。

类也可以有@RequestMapping,但是每个方法也应该有自己的“@RequestMapping”,请参见下面的示例。

@Controller
@RequestMapping("/appointments")
public class AppointmentsController {

    private final AppointmentBook appointmentBook;

    @Autowired
    public AppointmentsController(AppointmentBook appointmentBook) {
        this.appointmentBook = appointmentBook;
    }

    @RequestMapping(method = RequestMethod.GET)
    public Map<String, Appointment> get() {
        return appointmentBook.getAppointmentsForToday();
    }

    @RequestMapping(value="/{day}", method = RequestMethod.GET)
    public Map<String, Appointment> getForDay(@PathVariable @DateTimeFormat(iso=ISO.DATE) Date day, Model model) {
        return appointmentBook.getAppointmentsForDay(day);
    }

    @RequestMapping(value="/new", method = RequestMethod.GET)
    public AppointmentForm getNewForm() {
        return new AppointmentForm();
    }

    @RequestMapping(method = RequestMethod.POST)
    public String add(@Valid AppointmentForm appointment, BindingResult result) {
        if (result.hasErrors()) {
            return "appointments/new";
        }
        appointmentBook.addAppointment(appointment);
        return "redirect:/appointments";
    }
}
