【问题描述】：

我正在运行启用了基本身份验证的 Spring Boot 应用程序和启用了 UI 安全性的 Spring Boot 管理员。

我的 Spring Boot 客户端无法注册到 Spring Boot 管理服务器。以下是日志：

下面是我来自管理服务器的 webSecurity 配置类

@SpringBootApplication
@EnableAdminServer
@EnableAutoConfiguration
@Configuration
public class SpringStarterAdminApplication 

    public static void main(String[] args) 
        SpringApplication.run(SpringStarterAdminApplication.class, args);
    


    // Added for spring boot security login ui for admin



        public static class SecuritySecureConfig extends WebSecurityConfigurerAdapter 
        private final String adminContextPath;

        public SecuritySecureConfig(AdminServerProperties adminServerProperties) 
            this.adminContextPath = adminServerProperties.getContextPath();
        

        @Override
        protected void configure(HttpSecurity http) throws Exception 
            // @formatter:off
            SavedRequestAwareAuthenticationSuccessHandler successHandler = new SavedRequestAwareAuthenticationSuccessHandler();
            successHandler.setTargetUrlParameter("redirectTo");
            successHandler.setDefaultTargetUrl(adminContextPath + "/");

            http.authorizeRequests()
                .antMatchers(adminContextPath + "/assets/**").permitAll() 
                .antMatchers(adminContextPath + "/login").permitAll()
                .anyRequest().authenticated() 
                .and()
            .formLogin().loginPage(adminContextPath + "/login").successHandler(successHandler).and() 
            .logout().logoutUrl(adminContextPath + "/logout").and()
            .httpBasic().and() 
            .csrf()
                .csrfTokenRepository(CookieCsrfTokenRepository.withHttpOnlyFalse())  
                .ignoringAntMatchers(
                    "/instances",   
                    "/actuator/**"  
                );
            // @formatter:on
        
    

不确定是什么阻止了客户端注册到管理服务器。

【问题讨论】：

我也面临同样的问题。你有什么解决办法吗？？

【参考方案1】：

内部配置类也应该用@Configuration注解。

如果你将它重构为一个单独的类，那就更好了。
