Question

问题是我想使用对象AdminLogin来验证管理员。

这是AdminLogin类

package com.mintad.admin.beans;

import java.io.Serializable;

import org.springframework.stereotype.Component;
/**
 * 
 * Used to authenticate admin
 *
 */

@Component("adminLogin")
public class AdminLogin implements Serializable {

    private static final long serialVersionUID = -6394045014528037520L;

    private String username;

    private String password;

    public AdminLogin() {
    }

    public AdminLogin(String username, String password) {
        super();
        this.username = username;
        this.password = password;
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

和控制器方法

    @ModelAttribute("adminLogin")
        public AdminLogin createModel() {
            return new AdminLogin();
        }

@RequestMapping(value = "/admin/login", method = RequestMethod.POST)
public ModelAndView login(@ModelAttribute AdminLogin adminLogin, HttpServletRequest request,
        @RequestParam(value = "error", required = false) String error, @RequestParam(value = "logout", required = false) String logout) {
    LOGGER.debug("admin login page");
    ModelAndView model = new ModelAndView();
    model.addObject("adminLogin", adminLogin);
    if (error != null) {
        model.addObject("error", "Invalid username and password!");
    }

    if (logout != null) {
        model.addObject("msg", "You've been logged out successfully.");
    }

    model.setViewName("/admin/index");

    LOGGER.debug("returning admin login page");

    return model;

}

@RequestMapping(value = "/admin/login", method = RequestMethod.GET)
public String greetingForm(Model model) {
    model.addAttribute("adminLogin", new AdminLogin());
    return "/admin/login";
}

问题是表格是通过GET提交的，尽管它的POST如下;

<form class="m-t" role="form" th:action="@{/admin/login}" th:object="${adminLogin}" method=" POST" autocomplete="off">
                <div th:if="${param.error}" class="alert alert-danger">Invalid username and password.</div>
                <div th:if="${param.logout}" class="alert alert-success">You have been logged out.</div>
                <div class="form-group">
                    <input type="text" class="form-control" id="username" name="username" th:field="*{username}" placeholder="Username" required="" />
                </div>
                <div class="form-group">
                    <input type="password" class="form-control" id="password" name="password" th:field="*{password}" placeholder="Password" required="" />
                </div>
                <input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}" />
                <button type="submit" class="btn btn-primary block full-width m-b">Login</button>
                <a href="#"><small>Forgot password?</small></a>
                <p class="text-muted text-center">
                    <small>Do not have an account?</small>
                </p>
                <a class="btn btn-sm btn-white btn-block" href="register.html">Create an account</a>
            </form>

我已经添加了GET以确认我的感觉，也因为我已经看过有关如何在登录表单中使用对象的示例。

请帮我解决这个问题，或者请你更清洁地实现我的目标。

谢谢！

尝试删除表单中method=" POST"中的空格。它是case-insensitive，但可接受的值为GET和POST。默认方法是GET。

带有弹簧4的Thymeleaf形式：Etat HTTP 405 - 请求方法＆＃39; GET＆＃39;不支持
