我正在尝试为我的 bootstrap 应用程序添加自定义登录页面。我在关注 this教程。我无法使用我的自定义登录页面。
这是我的 pom.xml:
...
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-commons</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<scope>test</scope>
</dependency>
...
配置文件
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);
}
}
安全配置文件
@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 localhost:8080/login 时,我会收到以下错误:
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
但是,当我尝试 localhost:8080/时,它将成功重定向到我在 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 粘贴到/src/main/resources/templates 和/src/main/webapp/和/src/main/webapp/templates 中,但它仍然无法正常工作!
最佳答案
好的,所以这是 pom.xml 中的一个简单错误。
<!--<resources>-->
<!--<resource>-->
<!--<directory>src/main/resources</directory>-->
<!--<includes>-->
<!--<include>*</include>-->
<!--</includes>-->
<!--<filtering>true</filtering>-->
<!--</resource>-->
<!--</resources>-->
在我从 pom 文件中注释掉这些(如您所见)之后,它运行良好。至少上面的代码可能对其他人有用。
