Spring Boot jsp文件找不到404奇怪的前缀

Question

我目前正在学习Spring/Spring Boot，我正试图编码忘记密码的功能。所有其他功能，如登录等都按预期工作，但由于某种原因重定向到重置密码页面不起作用，并给了我以下错误，其中它查找具有奇怪前缀的jsp。

有一个意想不到的错误(type=Not Found, status=404).

JSP文件[/reset-password]/WEB-INF/jsp/reset-password.jsp] not found

文件夹结构

生成如下链接:http://localhost:8080/reset-password/{a-random-uuid}

reset-password.jsp

<%@ include file="includes/header.jsp" %>
<div class="panel panel-primary">
<div class="panel-heading">
<h3 class="panel-title">Reset your password</h3>
</div>
<div class="panel-body">
<form:form modelAttribute="resetPasswordForm" role="form">
<form:errors cssClass="error" />
<div class="form-group">
<form:label path="password">Type new password</form:label>
<form:password path="password" class="form-control"
placeholder="Password" />
<form:errors cssClass="error" path="password" />
</div>
<div class="form-group">
<form:label path="retypePassword">Retype new password</form:label>
<form:password path="retypePassword" class="form-control"
placeholder="Retype password" />
<form:errors cssClass="error" path="retypePassword" />
</div>
<button type="submit" class="btn btn-primary">Reset password</button>
</form:form>
</div>
</div>
<%@include file="includes/footer.jsp"%>

我的积分控制器:

[imports]
@Controller
@RequestMapping("/reset-password/{resetPasswordCode}")
public class ResetPasswordController {
private final UserCommandService userCommandService;
public ResetPasswordController(UserCommandService userCommandService) {
this.userCommandService = userCommandService;
}
@GetMapping
public String forgotPassword(Model model){
model.addAttribute(new ResetPasswordForm());
return "reset-password";
}
@PostMapping
public String resetPassword(@PathVariable String resetPasswordCode, @Validated ResetPasswordForm resetPasswordForm, BindingResult result, RedirectAttributes redirectAttributes){
if (result.hasErrors()) {
return "reset-password";
}
try{
userCommandService.resetPassword(resetPasswordCode, resetPasswordForm.getPassword());
MyUtils.flash(redirectAttributes, "success", "Password was changed");
return "redirect:/login";
} catch (NoSuchElementException e) {
result.reject("Url is invalid");
return "reset-password";
}
}
}

Resetpasswordform

package com.learningspring.springdiproject.dto;
import constraints.Password;
import constraints.RetypePassword;
@RetypePassword
public class ResetPasswordForm {
@Password
private String password;
@Password
private String retypePassword;

public String getRetypePassword() {
return retypePassword;
}
public void setRetypePassword(String retypePassword) {
this.retypePassword = retypePassword;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

我很确定我的pom和控制器是正确的，因为我看不出这个控制器和我的其他控制器之间的区别。

注意:Password和Retype Password只是自定义约束，检查，密码的大小，如果两个密码的形式数学等。

我想在某个地方，视图控制器搞砸了，把前缀放在那里。但我不知道这是从哪里来的。其他有同样问题的人在他们的文件夹中没有jasper或者文件夹结构错误，但我仔细检查了这些错误。

尝试更改以下属性以/

开头

spring.mvc.view.prefix= /WEB-INF/jsp/

这将允许spring搜索到您的webapp/WEB-INF/jsp路径的子文件夹。
