我正在尝试为我的Bootstrap应用程序添加自定义登录页面。我正在遵循这个教程。但是我无法让它与我的自定义登录页面一起工作。
这是我的pom.xml:

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");
}
}
我打开了所有的URL,以便检查是否可以看到“/login”。 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;
}
}
}
当我尝试访问 localhost:8080/login 时,会出现以下错误:
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,当我尝试访问localhost:8080/时,它会成功重定向到我在MvcConfig.java中指定的index.html。
这是我的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>
我将我的login.html文件复制到了/src/main/resources/templates、/src/main/webapp/ 和 /src/main/webapp/templates下,但仍然无法使用!
registry.addViewController("/login").setViewName("login");
