WebSecurityConfig：添加 属性 需要 Bean？

Question

出于某种原因，每当我尝试向此 class 添加 属性 时，应用程序就会中断。无法弄清楚我需要配置哪个构造函数。

    @Configuration
    @AllArgsConstructor
    @EnableWebSecurity
    public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
    
        private final AppUserService appUserService;
        private final BCryptPasswordEncoder bCryptPasswordEncoder;
    
        //without this line it works
        private String newProp;
    
        private FacebookConnectionSignup facebookConnectionSignup;
    
        @Override
        protected void configure(AuthenticationManagerBuilder auth) throws Exception {
            auth.authenticationProvider(daoAuthenticationProvider());
        }
    
        @Bean
        public DaoAuthenticationProvider daoAuthenticationProvider() {
            DaoAuthenticationProvider provider =
                    new DaoAuthenticationProvider();
            provider.setPasswordEncoder(bCryptPasswordEncoder);
            provider.setUserDetailsService(appUserService);
            return provider;
        }
    
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            http
                    .csrf().disable()
                    .authorizeRequests()
                    .antMatchers("/api/v*/registration/**")
                    .permitAll()
                    .anyRequest()
                    .authenticated().and()
                    .formLogin();
        }
        @Bean
        public ProviderSignInController providerSignInController() {
            ConnectionFactoryLocator connectionFactoryLocator =
                    connectionFactoryLocator();
            UsersConnectionRepository usersConnectionRepository =
                    getUsersConnectionRepository(connectionFactoryLocator);
            ((InMemoryUsersConnectionRepository) usersConnectionRepository)
                    .setConnectionSignUp(facebookConnectionSignup);
            return new ProviderSignInController(connectionFactoryLocator,
                    usersConnectionRepository, new FacebookSignInAdapter());
        }
    
        private ConnectionFactoryLocator connectionFactoryLocator() {
            ConnectionFactoryRegistry registry = new ConnectionFactoryRegistry();
            registry.addConnectionFactory(new FacebookConnectionFactory("appId", "appSecret"));
            return registry;
        }
    
        private UsersConnectionRepository getUsersConnectionRepository(ConnectionFactoryLocator
                                                                               connectionFactoryLocator) {
            return new InMemoryUsersConnectionRepository(connectionFactoryLocator);
        }
    }

启动 ApplicationContext 时出错。要显示条件报告，请重新 运行 您的应用程序并启用 'debug'。 2021-12-17 00:40:17.874 错误 21160 --- [主要] o.s.b.d.LoggingFailureAnalysisReporter :

描述：

com.example.demo.security.config.WebSecurityConfig 中构造函数的参数 2 需要一个 'java.lang.String' 类型的 bean，但找不到。

操作：

考虑在您的配置中定义类型为 'java.lang.String' 的 bean。

而不是 AllArgsConstructor 使用 RequiredArgsConstructor 注释并最终完成此 属性:

private final FacebookConnectionSignup facebookConnectionSignup;
