Java 创建名为'；springSecurityFilterChain'；

当我在springboot中使用spring安全性时，出现了一个错误

然后我用谷歌搜索它，我仍然无法解决它

然后我参考了spring文档（很简单），我做了配置，我仍然有一个问题

这是我的错误：

这是我的安全配置：

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {

@Bean
UserDetailsService customUserService() {
    return new CustomUserService();
}

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.authorizeRequests()
            .antMatchers("/**").access("hasRole('ROLE_USER')")
            .antMatchers("/admin/**").access("hasRole('ROLE_ADMIN')")
            .anyRequest().authenticated().and() 
            .rememberMe().tokenValiditySeconds(60 * 60 * 24 * 7).key("").and() 
            .formLogin().loginPage("/login").failureUrl("/login?error").permitAll().and() 
            .logout().permitAll(); 
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.userDetailsService(customUserService());
}
}

这是CustomUserService

@Service
public class CustomUserService implements UserDetailsService {

@Autowired
private UserService userService;

@Override
public UserDetails loadUserByUsername(String s) throws UsernameNotFoundException {
    System.out.println("loaduser " + s);
    User user = userService.getUserByUsername(s);
    if (user == null || user.getIsDel() == 1) {
        throw new UsernameNotFoundException("用户不存在或已被删除");
    }
    List<GrantedAuthority> auths = new ArrayList<>();
    for (Role role : user.getRoles()) {
        auths.add(new SimpleGrantedAuthority(role.getName()));
    }
    System.out.println("load finish");
    return new org.springframework.security.core.userdetails.User(s, user.getPwd(), auths);
}
}

@服务
公共类CustomUserService实现UserDetailsService{
@自动连线
私人用户服务；
@凌驾
public UserDetails loadUserByUsername（字符串s）引发UsernameNotFoundException{
System.out.println（“加载用户”+s）；
User=userService.getUserByUsername；
if（user==null | | user.getIsDel（）==1）{
抛出新的UsernameNotFoundException（“用户不存在或已被删除");
}
List auths=new ArrayList（）；
for（角色：user.getRoles（））{
add（新的SimpleGrantedAuthority（role.getName（））；
}
System.out.println（“加载完成”）；
返回新的org.springframework.security.core.userdetails.User（s，User.getPwd（），auths）；
}
}
