我在启动网站时遇到问题
这些是我认为可能是问题的文件
这是我的BlogUserDetails.java
package softuniBlog.Config;
import org.springframework.security.core.GrantedAuthority;
import org.springframework.security.core.authority.AuthorityUtils;
import org.springframework.security.core.userdetails.UserDetails;
import org.springframework.util.StringUtils;
import softuniBlog.Entity.User;
import java.util.ArrayList;
import java.util.Collection;
public class BlogUserDetails extends User implements UserDetails {
public BlogUserDetails(User user, ArrayList<String> roles) {
super(user.getEmail(), user.getFirstName(), user.getLastName(), user.getPassword());
this.roles = roles;
this.user = user;
}
public User getUser() {
return this.user;
}
@Override
public Collection<? extends GrantedAuthority> getAuthorities() {
String userRoles = StringUtils.collectionToCommaDelimitedString((this.roles));
return AuthorityUtils.commaSeparatedStringToAuthorityList(userRoles);
}
@Override
public String getUsername() {
return null;
}
@Override
public boolean isAccountNonExpired() {
return true;
}
@Override
public boolean isAccountNonLocked() {
return true;
}
@Override
public boolean isCredentialsNonExpired() {
return true;
}
@Override
public boolean isEnabled() {
return true;
}
private ArrayList<String> roles;
private User user;
}
这是WebSecurityConfig.java
package softuniBlog.Config;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.security.SecurityProperties;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.annotation.Order;

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@EnableWebSecurity
@Order(SecurityProperties.BASIC_AUTH_ORDER)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private UserDetailsService userDetailsService;
@Autowired
public void configAuthentication(AuthenticationManagerBuilder auth) throws Exception {
auth.userDetailsService(this.userDetailsService).passwordEncoder(new BCryptPasswordEncoder());
}
@Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests()
.anyRequest().permitAll()

.csrf();
}
}
我的问题是，当我启动应用程序时，出现以下错误

任何帮助将不胜感激，如有需要，我会提供更多代码
答案 0 :(得分：1)
我发现了一些要点：
您声明了<thymeleaf-layout-dialect.version>2.2.1</thymeleaf-layout-dialect.version>
但是没有添加依赖项本身吗？
然后您添加了thymeleaf-spring3，尽管您正在运行使用spring 5的spring boot 2应用程序？切换到thymeleaf-spring5看看是否有帮助。
答案 1 :(得分：0)
关于我的问题，我需要以下2个依赖项。
显然，该版本与您的春季版本有关。
我赞成mrkernelpanic的答案，因为它〜帮助〜使我得以解决。
但是我的贡献是给出了两个依赖项的xml。
“ 3.0.11.RELEASE”修复了我的问题，仅供参考。
new MyComponent(props)及以后
React.createElement(MyComponent, props).....................................
现在是原始问题。
您已定义此属性版本：
<properties>
<thymeleaf-layout-dialect.version>3.0.11.RELEASE</thymeleaf-layout-dialect.version>
</properties>
但是您不使用该属性，而是在SINGLE依赖项中使用硬编码版本：
（在您的问题下方粘贴）
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf</artifactId>
<version>${thymeleaf-layout-dialect.version}</version>
</dependency>
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf-spring5</artifactId>
<version>${thymeleaf-layout-dialect.version}</version>
</dependency>
我〜认为〜您需要第二个依赖项（请参阅上面的两个），并使要如何定义版本一致。 （硬代码或使用专有，但对于您的代码读者而言，请使其整洁清晰）
