Question

我一直在尝试在Tomcat中使用Eclipse中的Spring Hibernate Web示例。不幸的是，我收到以下警告：

警告：org.springframework.web.servlet.PageNotFound - 找不到映射用于在DispatcherServlet中使用URI [/ SpringMVCHibernate /]的HTTP请求名称＆＃39; appServlet＆＃39;

警告需要做什么？据我所知，我无法找到确切的解决方案。如果你能帮助我，我将不胜感激。

这是我的web.xml

Answer 1

你应该添加

<context:component-scan base-package="com.journaldev" />

Answer 2

控制器类代码：

package com.journaldev.spring;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.stereotype.Controller; 
import org.springframework.ui.Model; 
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 com.journaldev.spring.model.Person; 
import com.journaldev.spring.service.PersonService;

@Controller
public class PersonController {

    private PersonService personService;

    @Autowired(required = true)
    @Qualifier(value = "personService")
    public void setPersonService(PersonService ps) {
        this.personService = ps;
    }

    @RequestMapping(value = "/persons", method = RequestMethod.GET)
    public String listPersons(Model model) {
        model.addAttribute("person", new Person());
        model.addAttribute("listPersons", this.personService.listPersons());
        return "person";
    }

    // For add and update person both
    @RequestMapping(value= "/person/add", method = RequestMethod.POST)
    public String addPerson(@ModelAttribute("person") Person p) {

        if (p.getId() == 0) {
            //new person, add it
            this.personService.addPerson(p);
        } else {
            //existing person, call update
            this.personService.updatePerson(p);
        }

        return "redirect:/persons"; 
    }

    @RequestMapping("/remove/{id}")
    public String removePerson(@PathVariable("id") int id) {

        this.personService.removePerson(id);
        return "redirect:/persons";
    }

    @RequestMapping("/edit/{id}")
    public String editPerson(@PathVariable("id") int id, Model model) {
        model.addAttribute("person", this.personService.getPersonById(id));
        model.addAttribute("listPersons", this.personService.listPersons());
        return "person";
    }
}

在DispatcherServlet中找不到带有URI [/ SpringMVCHibernate /]的HTTP请求的映射，其名称为＆＃39; appServlet＆＃39;
