嗨,我正在創建一個春天mvc應用程序。春天的上下文似乎將控制器方法映射到錯誤的URL。Spring MVC URL映射
我已經以下控制器:
HelloWorldController
package com.springapp.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/hello")
public class HelloWorldController {
@RequestMapping(method = RequestMethod.GET)
public ModelAndView helloWorld() {
String message = "Hello World, Spring 3.0!";
return new ModelAndView("hello", "message", message);
}
}
ContactsController
package com.springapp.controller;
import com.springapp.form.Contact;
import com.springapp.service.ContactService;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.servlet.ModelAndView;
@Controller
@RequestMapping("/contacts")
public class ContactsController {
@Autowired
private ContactService contactService;
@RequestMapping(method = RequestMethod.GET)
public String listContacts(Model map) {
map.addAttribute("contact", new Contact());
map.addAttribute("contactList", contactService.listContacts());
return "contact";
}
@RequestMapping(value="{contactId}", method=RequestMethod.GET)
public String showContact(@PathVariable("contactId") Integer contactId) {
contactService.getContact(contactId);
return "redirect:/contacts";
}
@RequestMapping(value = "/add", method = RequestMethod.POST)
public String addContact(@ModelAttribute("contact") Contact contact, BindingResult result) {
contactService.addContact(contact);
return "redirect:/contacts";
}
@RequestMapping("/{contactId}/delete")
public String deleteContact(@PathVariable("contactId") Integer contactId) {
contactService.removeContact(contactId);
return "redirect:/contacts";
}
}
然而彈簧上下文映射它們爲:
INFO: Mapped URL path [/contacts/new] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/new.*] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/new/] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/addContact] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/addContact.*] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/addContact/] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/delete/{contactId}] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/delete/{contactId}.*] onto handler 'contactsController'
INFO: Mapped URL path [/contacts/delete/{contactId}/] onto handler 'contactsController'
INFO: Mapped URL path [/hello] onto handler 'helloWorldController'
INFO: Mapped URL path [/hello.*] onto handler 'helloWorldController'
INFO: Mapped URL path [/hello/] onto handler 'helloWorldController'
它在哪裏得到這些new
和addContact
模式?此外,映射/contacts
丟失。
你的問題中的日誌很奇怪,因爲它不符合你的'ContactsController'中的映射。你確定你發佈的代碼和日誌來自同一版本嗎? – davioooh
@davioooh順便說一句,我在前面的ContactsController中有一個'addContact'映射,後來我更新爲'add'。正如你所看到的,我也改變了'deleteContact'的映射,但它沒有生效。 –
你使用Eclipse來開發/運行你的項目嗎? – davioooh
