找不到Spring Boot jsp文件错误404奇怪前缀

Question

我目前正在学习Spring/Spring Boot，我正在尝试编写忘记密码功能。我的所有其他功能，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，并给我带来以下错误，其中它查找带有奇怪前缀的jsp。

有一个意外的错误（type=未找到，status=404）。

找不到JSP文件[/reset-password/WEB-INF/JSP/reset-password.JSP]

我的文件夹结构

我生成如下所示的链接：http://localhost:8080/reset-password/{a-随机-uuid}

重置密码。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"%>

我的重置控制器：

[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";
        }
    }
}

重置密码形式

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;
    }
}

属性文件

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

spring.datasource.url=jdbc:h2:~/test;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE
spring.datasource.username= spring

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有什么区别。

注意：密码和重新键入密码只是自定义约束，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，Viewcontroller搞糟了，把前缀放进去了。但我不知道这可能来自哪里。其他有相同问题的人的pom中没有jasper或错误的文件夹结构，但我仔细检查了这些错误。

Answer 1

尝试更改以下属性以/开头

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

这将允许spring搜索您的路径的子文件夹。
