【问题描述】：

我正在尝试制作一个 Spring Boot 应用程序，但是，我无法加载第一页。似乎（基于提出的许多类似问题）此错误可能有多种原因，但是，似乎没有一个原因可以解决导致此特定错误的问题。我觉得在 SO 上对这个问题有一些见解不会有什么坏处吗？

目前的错误是：

org.thymeleaf.exceptions.TemplateInputException: Error resolving template "login", template might not exist or might not be accessible by any of the configured Template Resolvers

控制器方法

@Controller
public class UserController 
    @Autowired
    private UserService userService;

    @Autowired
    private SecurityService securityService;

    @Autowired
    private UserValidator userValidator;

    @Autowired
    UserRepository userRepository;
  @RequestMapping(value = "/registration", method = RequestMethod.GET)
    public String registration(Model model) 
        model.addAttribute("userForm", new User());

        return "registration";
    

    @RequestMapping(value = "/registration", method = RequestMethod.POST)
    public String registration(@ModelAttribute("userForm") User userForm, BindingResult bindingResult, Model model) 
        userValidator.validate(userForm, bindingResult);

        if (bindingResult.hasErrors()) 
            return "registration";
        

        userService.save(userForm);

        securityService.autologin(userForm.getUsername(), userForm.getPasswordConfirm());

        return "redirect:/welcome";
    

    @RequestMapping(value = "/login", method = RequestMethod.GET)
    public String login(Model model, String error, String logout) 
        if (error != null)
            model.addAttribute("error", "Your username and password is invalid.");

        if (logout != null)
            model.addAttribute("message", "You have been logged out successfully.");

        return "login";
    

    @RequestMapping(value = "/", "/welcome", method = RequestMethod.GET)
    public String welcome(Model model) 
        return "welcome";
    

网络配置文件

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter 
    @Autowired
    private UserDetailsService userDetailsService;

    @Bean
    public BCryptPasswordEncoder bCryptPasswordEncoder() 
        return new BCryptPasswordEncoder();
    

    @Override
    protected void configure(HttpSecurity http) throws Exception 
        http
                .authorizeRequests()
                    .antMatchers("/resources/**", "/registration").permitAll()
                    .anyRequest().authenticated()
                    .and()
                .formLogin()
                    .loginPage("/login")
                    .permitAll()
                    .and()
                .logout()
                    .permitAll();
    

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception 
        auth.userDetailsService(userDetailsService).passwordEncoder(bCryptPasswordEncoder());
    

Application.properties

## Spring DATASOURCE (DataSourceAutoConfiguration & DataSourceProperties)
spring.datasource.url = jdbc:mysql://localhost:3306/arearatingdb?useSSL=false
spring.datasource.username = root
spring.datasource.password = root


## Hibernate Properties
# The SQL dialect makes Hibernate generate better SQL for the chosen database
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

# Hibernate ddl auto (create, create-drop, validate, update)
spring.jpa.hibernate.ddl-auto = update

spring.mvc.view.prefix: /
spring.mvc.view.suffix: .jsp
spring.messages.basename=validation

我的目录设置如下：

请更新 spring.thymeleaf.enabled=false 在 application.properties 中
