Question

如果删除对日期的任何引用，表单会成功提交，但是当我包含日期字段时，我会收到以下错误：

出现意外错误（type = Bad Request，status = 400）。 object ='film'的验证失败。错误计数：1

我的代码如下：

addfilm.html

<form action="#" th:action="@{/film/addfilm}" th:object="${film}" method="post">
    <p>Title:</p> <input type="text" th:field="*{title}"/>
    <p>Director:</p> <input type="text" th:field="*{director}"/>
    <p>Description:</p> <input type="text" th:field="*{description}"/>
    <p>Release Date:</p> <input type="date" th:field="*{date}"/>
    <p/><input type="submit" value="Add"/>
</form>

film.java

package com.demo.spring.domain;

import java.util.Date;

public class Film {

    String title;
    String director;
    String description;
    Date date;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getDirector() {
        return director;
    }

    public void setDirector(String director) {
        this.director = director;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }


}

FilmController中

package com.demo.spring.controller;

import com.demo.spring.domain.Film;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@RequestMapping(value = "/film")
public class FilmController {

    @RequestMapping(value = "/addfilm", method = RequestMethod.GET)
    public String filmView(Model model)
    {
        Film film = new Film();
        model.addAttribute("film", film);
        return "addfilm";
    }

    @RequestMapping(value = "/addfilm", method = RequestMethod.POST)
    @ResponseBody
    public String film(Model model, @ModelAttribute("film") Film film)
    {
        return "This film was added to the database: "+film.getTitle()+" "+film.getDate();
    }
}

的HomeController

package com.demo.spring.controller;

import com.demo.spring.domain.Film;
import com.demo.spring.domain.User;
import com.demo.spring.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseBody;

import javax.servlet.http.HttpSession;
import java.util.List;

@Controller
public class HomeController {

    @Autowired
    UserService userService;

    @RequestMapping(value = "/", method = RequestMethod.GET )
 //   @ResponseBody
    public String index(Model model, HttpSession session)
    {
        if(session.getAttribute("login")==null)
        {
            return "redirect:/user/login";
        }

        Film film = new Film();
        model.addAttribute("film", film);

        List<User> users = userService.findAll();
        model.addAttribute("users",users);
        return "index";
    }
}

Answer 1

请尝试提交表单并检查浏览器为您的日期字段发送的格式。按Ctrl + Shift + i然后转到网络选项卡（如果您使用Chrome）。

格式因您使用的日期组件而异。字段通常具有格式＆＃34; yyyy-MM-dd＆＃34;。

如果您的请求中发送的格式为＆＃34; yyyy-MM-dd＆＃34;，请使用正确的格式对日期字段进行分配，如下所示：

@DateTimeFormat("yyyy-MM-dd")
Date date;

它会使它发挥作用。

希望这有帮助。

具有日期字段
