我正在尝试创建一个简单的注册和登录系统。当我尝试注册用户时，我向输入提供了所有信息，例如用户名、密码和确认密码，但是当我点击提交按钮时，它会将我重定向到/login，即使它应该是/welcome 页面，正如我在 Controller 。当我在特定映射的 Controller 中添加简单的调试时，没有任何反应，我想该方法甚至没有执行，有人可以看一下这段代码并告诉我这里出了什么问题吗？
@Controller
public class UserController {
private UserService userService;
private SecurityService securityService;
@Autowired
public UserController(UserService userService, SecurityService securityService) {
this.userService = userService;
this.securityService = securityService;
}
@RequestMapping(value = "/registration", method = RequestMethod.GET)
public String registration(Model model) {
// model.addAttribute("user", new User());
//
return "registration";
}
@RequestMapping(value = "/registration", method = RequestMethod.POST)
public String registration(@RequestParam("username") String username, @RequestParam("password")
String password, @RequestParam("confirmPassword") String confirmPassword,
Model model, HttpServletRequest request) {
User foundUser = userService.findByUsername(username);
if (foundUser != null) {
model.addAttribute("msgError", "That user already exists");
return "registration";
}
if (username.equals("") || username.length() < 2) {
model.addAttribute("msgError", "Wrong username");
return "registration";
}
if (!password.equals(confirmPassword)) {
model.addAttribute("msgError", "Passwords can not be different");
return "registration";
}
User user = new User(request.getParameter("username"), request.getParameter("password"), request.getParameter("confirmPassword"));
securityService.autoLogin(username, password);
userService.addUser(user);
model.addAttribute("msgSuccess", "User registered successfully");
return "redirect:/welcome";
}
@RequestMapping(value = "/login", method = RequestMethod.GET)
public String login(Model model, String error, String logout) {
if (error != null)
model.addAttribute("msgError", "Your username and password is invalid");
if (logout != null)
model.addAttribute("msgError", "You have been logged out successfully");
return "login";
}
}
注册JSP如下
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>Watchers - Registration</title>
</head>
<body>
<div class="container">
<form method="POST" action="registration" class="sign-form">
<h2 class="sign-form-heading">Create an new account</h2>
<p><input type="text" name="username" /></p>
<p><input type="text" name="password" /></p>
<p><input type="text" name="confirmPassword" /></p>
<input type="submit" value="Submit" />
</form>
</div>
</body>
</html>
最佳答案
我认为这是因为您的表单action-value。
尝试使用spring的taglib准备action值
在这个例子中它有前缀 spring
<spring:url value="/registration" var="url"/>
<form method="POST" action="${url}" class="sign-form">
编辑:
根据您的评论，我想问几个问题:
如何使用 web.xml 中的 spring-security 或 security-constraints 来保护/保护您的 Web 应用程序？
/registration路径也受到保护/安全吗？如果是，并且您的登录配置引用了 /login，您将被重定向到 /login
关于java - 单击提交按钮时不执行任何操作，但应该注册用户，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56546911/
