表单未发布值，'browser edit and resend' 有效

Question

我正在使用 Spring mvc web 提交表单。表单呈现良好，但是当我提交此表单时，我收到 http 状态代码 400，但是如果我使用 firefox 的 'edit and resend' 函数，它会触发相应的控制器方法（当我提交此表单时不会发生这种情况来自 html）。但是还有另一个问题，当我检查我的 modelAttribute object 时，在那个控制器方法中，我发现这个 object 中的所有内容都是空的。事实并非如此，因为我在此表单中提交值。

    <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
    <%@ include file="include.jsp"%>
    <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
    <title>${message}</title>
    </head>
    <body>
        General:
<br>
<form:form modelAttribute="initialMatchConfiguration" action="../match/configure" method="post" >
    Date and time:
    <form:input path="dateAndTimeOfMatch" type="text" />
    <br> Match Type:
    <form:select path="matchType">
        <option value="friendly">friendly</option>
        <option value="international">international</option>
        <option value="domestic">domestic</option>
        <option value="local">local tournament</option>
    </form:select>
    <br> Match Rules Configuration:
    <form:select path="matchConfigurationId">
        <option value="0">Random</option>
        <option value="1">T20</option>
        <option value="2">One Day</option>
        <option value="3">Test</option>
    </form:select>
    <button type="button">Create a new rule configuration</button>
    <br> Tournament:
    <form:input type="text" path="tournament" />
    <form:hidden path="tournamentId"/>
    <button type="button">Create a new Tournament</button>
    <br> Played at Stadium:
    <form:input type="text" path="stadium" />
    <form:hidden path="stadiumId"/>
    <button type="button">Create a new stadium</button>
    <br> <input type="submit" value="Save" />
</form:form>
    </body>
    </html>

渲染表单的方法如下：

    @RequestMapping(value = "/match/create", method = RequestMethod.GET)
public String  createMatch(Model model){
    model.addAttribute("initialMatchConfiguration", new InitialMatchConfiguration());
    return "config-match-initial";
}

提交表单的方法如下：

@RequestMapping(value = "/match/configure", method = RequestMethod.POST)
public String  configureMatch(@ModelAttribute("initialMatchConfiguration") InitialMatchConfiguration initialMatchConfig, Model model){
    System.out.println(initialMatchConfig);
    return "config-match-team";
}

初始匹配配置class

public class InitialMatchConfiguration {
private Date dateAndTimeOfMatch;
private String matchType;
private Long matchConfigurationId;
private Long tournamentId;
private Long stadiumId;
private String tournament;
private String stadium;
public Date getDateAndTimeOfMatch() {
    return dateAndTimeOfMatch;
}
public void setDateAndTimeOfMatch(Date dateAndTimeOfMatch) {
    this.dateAndTimeOfMatch = dateAndTimeOfMatch;
}
public String getMatchType() {
    return matchType;
}
public void setMatchType(String matchType) {
    this.matchType = matchType;
}
public Long getMatchConfigurationId() {
    return matchConfigurationId;
}
public void setMatchConfigurationId(Long matchConfigurationId) {
    this.matchConfigurationId = matchConfigurationId;
}
public Long getTournamentId() {
    return tournamentId;
}
public void setTournamentId(Long tournamentId) {
    this.tournamentId = tournamentId;
}
public Long getStadiumId() {
    return stadiumId;
}
public void setStadiumId(Long stadiumId) {
    this.stadiumId = stadiumId;
}
public String getTournament() {
    return tournament;
}
public void setTournament(String tournament) {
    this.tournament = tournament;
}
public String getStadium() {
    return stadium;
}
public void setStadium(String stadium) {
    this.stadium = stadium;
}

}

从 firefox 编辑和重新发送工具触发时请求：

dateAndTimeOfMatch=&matchType=friendly&matchConfigurationId=0&tournament=&tournamentId=&stadium=&stadiumId=

Answer 1

根本原因： 将 dateAndTimeOfMatch 的类型从文本更改为日期

并在表格 class 中：

    @DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
    private Date dateAndTimeOfMatch;

表格：

 <form:form modelAttribute="initialMatchConfiguration" action="../match/configure" method="post" >
Date and time:
<form:input path="dateAndTimeOfMatch" type="date" />
<br> Match Type:
<form:select path="matchType">
    <option value="friendly">friendly</option>
    <option value="international">international</option>
    <option value="domestic">domestic</option>
    <option value="local">local tournament</option>
</form:select>
<br> Match Rules Configuration:
<form:select path="matchConfigurationId">
    <option value="0">Random</option>
    <option value="1">T20</option>
    <option value="2">One Day</option>
    <option value="3">Test</option>
</form:select>
<button type="button">Create a new rule configuration</button>
<br> Tournament:
<form:input type="text" path="tournament" />
<form:hidden path="tournamentId"/>
<button type="button">Create a new Tournament</button>
<br> Played at Stadium:
<form:input type="text" path="stadium" />
<form:hidden path="stadiumId"/>
<button type="button">Create a new stadium</button>
<br> <input type="submit" value="Save" />

InitialMatchConfiguration.java:

 public class InitialMatchConfiguration {

@DateTimeFormat(iso = DateTimeFormat.ISO.DATE)
private Date dateAndTimeOfMatch;
private String matchType;
private Long matchConfigurationId;  
private Long tournamentId;
private Long stadiumId;
private String tournament;
private String stadium;

 //getters and setters

}

控制器：

@RequestMapping(value = "/match/configure", method = RequestMethod.POST)
    public String  configureMatch(@ModelAttribute("initialMatchConfiguration") InitialMatchConfiguration initialMatchConfig, Model model){
        System.out.println(initialMatchConfig.toString());

        return "config-match-team";
    }

响应：

** InitialMatchConfiguration [dateAndTimeOfMatch=1 月 10 日星期二 05:30:00 IST 2017，matchType=international，matchConfigurationId=2，tournamentId=null，stadiumId=null，tournament=sa，stadium=]**
