我猜这与此配置类中的自动接线阿曲布他有关：

@Configuration
@ComponentScan(value="spring.example")
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UsuarioService usuario;

    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth
            .userDetailsService(usuario)
            .passwordEncoder(encoder());
    }

    private Md5PasswordEncoder encoder() {
        return new Md5PasswordEncoder();
    }

    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
                .disable()
            .authorizeRequests()
                .antMatchers("/acesso/erro").permitAll()
                .antMatchers("/resources/**").permitAll()
                .anyRequest().authenticated()
                .and()
            .formLogin()
                .loginPage("/acesso/login").permitAll()
                .loginProcessingUrl("/login").permitAll()
                .usernameParameter("login")
                .passwordParameter("senha")
                .defaultSuccessUrl("/acesso/start")
                .failureUrl("/acesso/login")
                .and()
            .rememberMe()
                .key("lembrete")
                .useSecureCookie(true)
                .and()
            .logout()
                .logoutUrl("/logout")
                .logoutSuccessUrl("/acesso/login").permitAll();
    }

}

我的类UsuarioService.java有以下实现：

@Service
public class UsuarioService implements UserDetailsService {

    private UsuarioDao usuario;

    @Transactional(readOnly = true, propagation = Propagation.SUPPORTS)
    public UserDetails loadUserByUsername(String arg0) throws UsernameNotFoundException {
        Usuario account = usuario.findByField("login", arg0);

        if(account==null) {
            throw new UsernameNotFoundException("No such user: " + arg0);
        } else if (account.getAutorizacao().isEmpty()) {
            throw new UsernameNotFoundException("User " + arg0 + " has no authorities");
                    }

        boolean accountIsEnabled = true;
        boolean accountNonExpired = true;
        boolean credentialsNonExpired = true;
        boolean accountNonLocked = true;

        return new User(account.getLogin(), account.getSenha(), accountIsEnabled, accountNonExpired, credentialsNonExpired, accountNonLocked, getAuthorities(account.getAutorizacao()));

    }

    public List<String> getRolesAsList(List<Autorizacao> list) {
        List <String> rolesAsList = new ArrayList<String>();
        for(Autorizacao role : list){
            rolesAsList.add(role.getNome());
        }
        return rolesAsList;
    }

    public static List<GrantedAuthority> getGrantedAuthorities(List<String> roles) {
        List<GrantedAuthority> authorities = new ArrayList<GrantedAuthority>();
        for (String role : roles) {
            authorities.add(new SimpleGrantedAuthority(role));
        }
        return authorities;
    }

    public Collection<? extends GrantedAuthority> getAuthorities(List<Autorizacao> list) {
        List<GrantedAuthority> authList = getGrantedAuthorities(getRolesAsList(list));
        return authList;
    }

}

@服务
公共类USUARIService实现UserDetailsService{
私人用武之地；
@事务性（只读=true，传播=propagation.SUPPORTS）
public UserDetails loadUserByUsername（字符串arg0）引发UsernameNotFoundException{
Usuario帐户=Usuario.findByField（“登录”，arg0）；
如果（帐户==null）{
抛出新的UsernameNotFoundException（“没有这样的用户：+arg0”）；

布尔值accountIsEnabled=true；

布尔值accountNonLocked=true；
返回新用户（account.getLogin（）、account.getSenha（）、accountIsEnabled、accountNonExpired、credentialsnexpired、accountNonLocked、getAuthorities（account.getautorizao（））；

公共列表获取角色列表（列表列表）{

}
public Collection您正在SpringConfig中自动连接一个具体的类（UsuarioService
），而不是一个接口（UserDetailsService
）
您应该在配置中自动连线UserDetailsService
：
@Autowired
private UserDetailsService usuario;

好的，我现在可以试试，但是当我需要（并且我会）自定义UserDetailsService实现时？您已经为自定义实现提供了UsuarioService
类，该类实现了UserDetailsService
，是Spring管理的bean。Spring将注入（并使用）当在config.Ok中连接UserDetailsService依赖项时，我现在可以尝试这个实现，但是当我需要时（我会）自定义UserDetailsService实现？您已经为自定义实现提供了UsuarioService
