我想爲我的自舉應用程序添加自定義登錄頁面。我正在關注this教程。我無法使用自定義登錄頁面進行工作。春季開機自定義登錄頁面
這裏是我的pom.xml：
...

<artifactId>spring-data-commons</artifactId>

MvcConfig.java
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
public class MvcConfig extends WebMvcConfigurerAdapter {
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("forward:/index.html");
registry.addViewController("/login").setViewName("login");
}
}
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");
}
}
我打開了所有的網址，所以我只是檢查我是否可以看到/登錄或不。 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;
}
}
}
當我嘗試本地主機：8080 /登錄我會收到以下錯誤：
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.
There was an unexpected error (type=Internal Server Error, status=500).
Error resolving template "login", template might not exist or might not be accessible by any of the configured Template Resolvers
然而，當我嘗試本地主機：8080 /它會成功重定向到index.html作爲我在MvcConfig.java中指定。
這裏是我的login.html代碼：
<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>
我貼我的login.html在/ src目錄/主/資源/模板和/ src目錄/主/ web應用/和/ src目錄/主/ web應用/模板它仍然沒有工作！
您查看控制器配置必須攔截「登錄」請求並重定向到不存在的「登錄」頁面，因此出現錯誤。這是繞過了thymeleaf視圖解析器。你嘗試刪除該行：'registry.addViewController（「/ login」）。setViewName（「login」）;'從你的MvcConfig？ –
@ FinbarrO'Brien是的，嘗試過。實際上，我嘗試添加其他類似login1的東西，並將相應的login1.html放在模板中，但我也得到了同樣的錯誤。 – D3GAN
您是將您的應用程序構建爲war文件還是可執行jar？ –
