我正在尝试为我的引导应用程序添加自定义登录页。我在学习教程。我无法使用自定义登录页

FrontendApp.java:

import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Import;

import ch.qos.logback.classic.Logger;

 @SpringBootApplication
 @Import(value = MvcConfig.class)
 public class FrontendApp {

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

      public static void main(String[] args) {

          SpringApplication app = new SpringApplication(FrontendApp.class);
          app.run(args);
     }

}
SecurityConfiguration.java

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Autowired
    private CustomAuthenticationProvider customAuthenticationProvider;

    @Autowired
    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
         auth.authenticationProvider(this.customAuthenticationProvider);
    }

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

}
我打开了所有的url,所以我可以检查我是否可以查看/登录。 CustomAuthenticationProvider.java

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {    

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


    public CustomAuthenticationProvider() {
        logger.info("*** CustomAuthenticationProvider created");
    }

    @Override
    public boolean supports(Class<?> authentication) {
         return UsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication);
    }

    @Override
    public Authentication authenticate(Authentication authentication) throws AuthenticationException {

        if(authentication.getName().equals("karan")  && authentication.getCredentials().equals("saman")) {
            List<GrantedAuthority> grantedAuths = new ArrayList<>();
            grantedAuths.add(new SimpleGrantedAuthority("ROLE_USER"));
            grantedAuths.add(new SimpleGrantedAuthority("ROLE_ADMIN"));
            return new UsernamePasswordAuthenticationToken(authentication.getName(), authentication.getCredentials(), grantedAuths);
         } else {
              return null;
         }
    }

}
但是,当我尝试localhost:8080/时,它将成功重定向到index.html,正如我在MvcConfig.java中指定的那样

以下是我的login.html代码:

   <html xmlns="http://www.w3.org/1999/xhtml" 
         xmlns:th="http://www.thymeleaf.org" 
         xmlns:sec="http://www.thymeleaf.org/thymeleaf-extras-springsecurity3"
         xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">

<head>
    <meta charset="utf-8" />
    <title>k</title> 
</head>

K

我将login.html粘贴到/src/main/resources/templates和/src/main/webapp/和/src/main/webapp/templates中,但仍然无法工作

好的,这是pom.xml中的一个简单错误

<!--<resources>-->
        <!--<resource>-->

            <!--<includes>-->

在我从pom文件中注释掉这些(如您所见)后,它工作得非常好。至少上述代码可能对其他人有用。

您查看控制器配置时必须拦截“登录”请求并重定向到不存在的“登录”页面,因此出现错误。这是绕过thymeleaf视图解析器。您是否尝试删除以下行:
registry.addViewController(“/login”).setViewName(“login”)从你的MvcConfig?@FinbarrO'Brien是的,试过了。事实上,我尝试添加类似login1的其他内容,并将相应的login1.html放入模板中,但我也遇到了同样的错误。您是将应用程序构建为war文件还是可执行jar?@FinbarrO'Brien我正在使用嵌入式Tomcat并将其构建为可执行jar。
