Spring Boot jsp file not found Error 404 weird prefix

I am currently learning Spring/Spring Boot and I am trying to code a forgot password function. All my other functions, like login etc. are working as intended, but redirecting to an reset-password page does not work for some reason and gives me the following error, in which it looks for the jsp with a weird prefix.

There was an unexpected error (type=Not Found, status=404).

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

My folder structure

I generate links that look like so: 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"%>

My reset-controller:

[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";
        }
    }
}

The 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;
    }
}

I am pretty sure my pom and controller are right, since I can’t see a difference between this controller and my other controllers.

Note: Password and Retype password are just custom constraints, that check, the size of the password and if the two passwords of the form math an such.

I think somewhere, the Viewcontroller messes up and puts the prefix in there. But I could not find out where that may come from. Others with the same problem didnt have jasper in their pom or the wrong folder structure, but I double checked those errors.

Answer

Try to change the following property to start with a /

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

This will allow spring to search into subfolders of your webapp/WEB-INF/jsp path.
