java - Thymeleaf 启动时出错

标签 java spring-mvc spring-boot thymeleaf

我在启动网站时遇到问题

这些是我认为可能有问题的文件

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.config.annotation.authentication.builders.AuthenticationManagerBuilder;
import org.springframework.security.config.annotation.method.configuration.EnableGlobalMethodSecurity;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.core.userdetails.UserDetailsService;
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()
                .and()
                .formLogin().loginPage("/login")
                .usernameParameter("email").passwordParameter("password")
                .and()
                .logout().logoutSuccessUrl("/login?logout")
                .and()
                .exceptionHandling().accessDeniedPage("/error/403")
                .and()
                .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，如果需要，我将提供更多代码

最佳答案

我发现的一些要点:

您声明 <thymeleaf-layout-dialect.version>2.2.1</thymeleaf-layout-dialect.version>

但没有添加依赖本身？

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？切换至thymeleaf-spring5看看这是否也有帮助。
