如何修复 Spring Boot 的 BasicAuth？

Question

我正在编写一个 SpringBoot 应用程序。 当我向 Postman 发出请求时 - 我经常收到此错误：

java.lang.NullPointerException: null
    at org.springframework.security.web.authentication.www.BasicAuthenticationFilter.authenticationIsRequired(BasicAuthenticationFilter.java:222) ~[spring-security-web-5.2.1.RELEASE.jar:5.2.1.RELEASE]
    at org.springframework.security.web.authentication.www.BasicAuthenticationFilter.doFilterInternal(BasicAuthenticationFilter.java:166) ~[spring-security-web-5.2.1.RELEASE.jar:5.2.1.RELEASE]
    at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:119) ~[spring-web-5.2.2.RELEASE.jar:5.2.2.RELEASE]

这是我的安全配置：

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    @Autowired
    private UserService userService;

    @Autowired
    private PasswordEncoder passwordEncoder;

    @Bean
    public PasswordEncoder getPasswordEncoder() {
        return new BCryptPasswordEncoder(8);
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
                .authorizeRequests()
                .antMatchers("/", "/registration", "/restaurants").permitAll()
                .anyRequest().authenticated()
                .and()
                .httpBasic()
                .and()
                .rememberMe()
                .and()
                .logout()
                .permitAll();

        //Set enable when frontend added
        http.csrf().disable();
    }

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

如何解决？ 我需要从邮递员那里请求，所以我不能更改登录表单。

转到 Postman 窗口中的Authorization选项卡（它在请求类型下）并选择“Basic Auth”并填写您的凭据，如果您正在执行除“/”、“/registration”、“/restaurants”之外的任何请求。
