java - 如何将资源文件夹中的html文件与Spring Boot连接起来？

问题描述

我的 SpringWebConfiguration.class 在这里：

@Configuration
@EnableWebSecurity
public class SpringSecurityConfig extends WebSecurityConfigurerAdapter {

    private static Logger logger = LoggerFactory.getLogger(SpringSecurityConfig.class);

    @Autowired
    private UserDetailsService userDetailsService;

    @Autowired
    private PasswordEncoder passwordEncoder;
    @Override
    public void configure(WebSecurity web) throws Exception {
        web.ignoring().antMatchers("/resources/**");
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        logger.info("-----configure(HttpSecurity http)");

        http.authorizeRequests()
                .antMatchers("/**").permitAll()
                .antMatchers("/admin/**").hasAnyRole("ADMIN")
                .antMatchers("/user/**").hasAnyRole("USER")
                .anyRequest().authenticated()
                .and()
                .formLogin()
                .loginProcessingUrl("/login")
                .loginPage("/login")//
                .defaultSuccessUrl("/userAccountInfo")//
                .failureUrl("/login?error=true")//
                .usernameParameter("username")//
                .passwordParameter("password")
                .defaultSuccessUrl("/")
                .permitAll().
                and().rememberMe().rememberMeParameter("remember-me").key("uniqueAndSecret").tokenValiditySeconds(1296000).userDetailsService(userDetailsService)
                .and()
                .logout().logoutRequestMatcher(new AntPathRequestMatcher("/logout")).logoutSuccessUrl("/")
                .deleteCookies("guid")
                .deleteCookies("JSESSIONID")
                .permitAll()
                .and().csrf().disable();
    }

    @Autowired
    public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        logger.info("-----configureGlobal(AuthenticationManagerBuilder auth)");
        auth.userDetailsService(userDetailsService).passwordEncoder(passwordEncoder);
    }
}

我的登录控制器：

@RestController
public class LoginController() {
@GetMapping("/login")
    public String login(Model model) {
        return "/login";
    }
}

我的html文件：

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <title>Bootstrap Example</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css">

    <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
    <h2>Stacked form</h2>
    <form th:action="@{/login}" method="post">
        <div class="form-group">
            <label for="email">Email:</label>
            <input type="email" class="form-control" id="email" placeholder="Enter email" name="email">
        </div>
        <div class="form-group">
            <label for="pwd">Password:</label>
            <input type="password" class="form-control" id="pwd" placeholder="Enter password" name="pswd">
        </div>
        <div class="form-group form-check">
            <label class="form-check-label">
                <input class="form-check-input" type="checkbox" name="remember"> Remember me
            </label>
        </div>
        <button type="submit" class="btn btn-primary">Submit</button>
    </form>
</div>
</body>
</html>

当我打开浏览器并转到“localhost:8080/login”时。它返回字符串“/login”，而不是 html 登录页面。为什么？也许我错过了一些连接到我的 html 文件的东西。我认为我的控制器需要类似 url 的东西来连接到 html 文件。我不明白它是如何正常工作的。请帮帮我！

解决方案

首先需要修改LoginController

@Controller
public class LoginController() {
  @GetMapping("/login")
  public String login(Model model) {
        return "/login";
  }
}

如果它不起作用，则将 html 转换为 jsp 页面。
