java - Spring页面重定向：找不到页面问题

Question

我正在尝试从这个站点运行一个示例项目。Jboss开始时没有任何错误但是当我进入路径时

http://localhost:8080/Spring3Hibernate/index

我收到异常“请求的资源不可用”。

我的 spring-servlet.xml 类是

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

和 web.xml 是

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

控制器类是

package main.java.net.viralpatel.contact.controller;

import java.util.Map;

import main.java.net.viralpatel.contact.form.Contact;
import main.java.net.viralpatel.contact.service.ContactService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
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;

@Controller
public class ContactController {

    @Autowired
    private ContactService contactService;

    @RequestMapping("/index")

    public String listContacts(Map<String, Object> map) {

        System.out.println("In Index method");

        map.put("contact", new Contact());
        map.put("contactList", contactService.listContact());

        return "contact";
    }

    @RequestMapping(value = "/add", method = RequestMethod.POST)
    public String addContact(@ModelAttribute("contact")
    Contact contact, BindingResult result) {
        System.out.println("in ADD method");

        contactService.addContact(contact);

        return "redirect:/index";
    }

    @RequestMapping("/delete/{contactId}")
    public String deleteContact(@PathVariable("contactId")
    Integer contactId) {

        System.out.println("IN delete method");

        contactService.removeContact(contactId);

        return "redirect:/index";
    }
}

当我尝试运行该项目时，我得到了

10:33:25,415 WARN  [PageNotFound] No mapping found for HTTP request with URI [/Spring3Hibernate/index] in DispatcherServlet with name 'spring'

在 Lib 文件夹中，我有这些罐子

我会非常感谢您宝贵的时间和帮助。我正在使用 eclipes 3.4 和 jboss 4.2

是http://localhost:8080/Spring3Hibernate/index还是http://localhost:8080/Spring3-Hibernate/index

请验证您的上下文路径是否正确

在您从中获取代码的站点中，web.xml 中的 servlet 映射是这样完成的。

<servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
 </servlet-mapping>

在您已在其上方发布的代码中

<url-pattern>/*</url-pattern>

网址模式意味着：

/ by itself is the default servlet called if there are no other matches.

和

/* mapping in web.xml it answers all requests except other path mappings.

检查并使用你真正想要的。

试试这个在类级别指定 RequestMapping 为

@Controller
@RequestMapping("/contact")
public class ContactController

然后在方法级别指定

@RequestMapping(value = "/list", method = RequestMethod.GET)
public String listContacts(Map<String, Object> map)

现在尝试将 URL 设为

“http://localhost:8080/Spring3Hibernate/contact/list”
