return appointmentBook.getAppointmentsForToday();
}
@RequestMapping(value="/{day}", method = RequestMethod.GET)
public Map
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”;
}
}
value的uri值为以下三类：
A） 可以指定为普通的具体值；
B) 可以指定为含有某变量的一类值(URI Template Patterns with Path Variables)；
C) 可以指定为含正则表达式的一类值( URI Template Patterns with Regular expressions);
example B)
@RequestMapping(value="/owners/{ownerId}", method=RequestMethod.POST)
public String findOwner(@PathVariable String ownerId, Model model) {
Owner owner = ownerService.findOwner(ownerId);
model.addAttribute(“owner”, owner);
return “displayOwner”;
}
example C)
@RequestMapping("/spring-web/{symbolicName:[a-z-]+}-{version:d.d.d}.{extension:.[a-z]}")
public void handle(@PathVariable String version, @PathVariable String extension) {
// …
}
}
2 consumes、produces 示例
cousumes的样例：
@Controller
@RequestMapping(value = “/pets”, method = RequestMethod.POST, consumes=“application/json”)
public void addPet(@RequestBody Pet pet, Model model) {
// implementation omitted
}
方法仅处理request Content-Type为“application/json”类型的请求。
produces的样例：
@Controller
@RequestMapping(value = “/pets/{petId}”, method = RequestMethod.GET, produces=“application/json”)
@ResponseBody
public Pet getPet(@PathVariable String petId, Model model) {
// implementation omitted
}
方法仅处理request请求中Accept头中包含了”application/json”

的请求，同时暗示了返回的内容类型为application/json;
3 params、headers 示例
params的样例：
@Controller
@RequestMapping("/owners/{ownerId}")
public class RelativePathUriTemplateController {
@RequestMapping(value = “/pets/{petId}”, method = RequestMethod.GET, params=“myParam=myValue”)
public void findPet(@PathVariable String ownerId, @PathVariable String petId, Model model) {
// implementation omitted
}
}
仅处理请求中包含了名为“myParam”，值为“myValue”的请求；
headers的样例：
@Controller
@RequestMapping("/owners/{ownerId}")
public class RelativePathUriTemplateController {
@RequestMapping(value = “/pets”, method = RequestMethod.GET, headers=“Referer=http://www.ifeng.com/”)
public void findPet(@PathVariable String ownerId, @PathVariable String petId, Model model) {
// implementation omitted
