无法返回百里香模板

Question

问题在于，浏览器没有输出 thymeleaf 模板，而是显示带有“login”一词的页面。我认为这与配置有关，但我找不到错误。可能有人知道如何解决这个问题

application.yml

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration;
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/getyourhotel
    password: *password*
    username: root
  jpa:
    database-platform: org.hibernate.dialect.MySQL8InnoDBDialect
    generate-ddl: true
    show-sql: true
    hibernate:
      ddl-auto: update
    properties:
      hibernate:
        globally_quoted_identifiers: true
        dialect: org.hibernate.dialect.MySQL8Dialect
        format_sql: true
  sql:
    init:
      mode: never
      continue-on-error: false
  thymeleaf:
    prefix: classpath:/templates/
    suffix: .html
    mode: HTML
    cache: false

application:
  title: getyourhotel
  version: 1.0

控制器

    @PostMapping("/login")
       public String login(@RequestBody @Valid User user, Model model) {
         UserDTO userDTO = userService.findUser(user);
         model.addAttribute("user", userDTO);
         return "login";
        }

Answer 1

控制器不是设置为@RestController吗？

如果是@RestController，则返回的登录字符串将作为正文返回。

在这种情况下，请将其更改为@Controller。
