spring-boot - 如何避免 spring-boot-admin 中的证书验证？

Question

以什么方式可以避免 spring-boot-admin 中的证书验证？

我在一个类中配置了 RestTemplate 以避免证书，但我不知道如何发送它，我猜它必须在客户端，spring-boot-admin-starter-client 自动工作。

这是避免证书验证的代码。

public class SSLUtil {

    public RestTemplate getRestTemplate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
        TrustStrategy acceptingTrustStrategy = new TrustStrategy() {
            @Override
            public boolean isTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                return true;
            }
        };
        SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy)
                .build();
        SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());
        CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
        HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
        requestFactory.setHttpClient(httpClient);
        RestTemplate restTemplate = new RestTemplate(requestFactory);
        return restTemplate;
    }

}

应用程序属性

spring.application.name=管理员-应用程序

服务器端口=1111

安全用户名=管理员

security.user.password=admin123

@Configuration
    public static class SecurityConfig extends WebSecurityConfigurerAdapter {
        @Override
        protected void configure(HttpSecurity http) throws Exception {
            // Page with login form is served as /login.html and does a POST on
            // /login
            http.formLogin().loginPage("/login.html").loginProcessingUrl("/login").permitAll();
            // The UI does a POST on /logout on logout
            http.logout().logoutUrl("/logout");
            // The ui currently doesn't support csrf
            http.csrf().disable().authorizeRequests()

                    // Requests for the login page and the static assets are
                    // allowed
                    // http.authorizeRequests()
                    .antMatchers("/login.html", "/**/*.css", "/img/**", "/third-party/**").permitAll();
            // ... and any other request needs to be authorized
            http.authorizeRequests().antMatchers("/**").authenticated();

            // Enable so that the clients can authenticate via HTTP basic for
            // registering
            http.httpBasic();
        }
    }

我将 Spring Boot Admin 2.1.3 与 Eureka 一起使用。

似乎 SBA 已从 RestTemplate 转移到 WebClient。所以我创建了一个 WebClient，它有一个 SSLContext 和一个信任管理器设置为InsecureTrustManagerFactory，它信任一切。然后我使用这个 webclient 并实例化 SBA 的 InstanceWebClient。不确定是否有更简单的方法，但这对我有用。

    private final AdminServerProperties adminServerProperties;

    public SslConfiguration(AdminServerProperties adminServerProperties) {
        this.adminServerProperties = adminServerProperties;
    }


    @Bean
    public InstanceWebClient instanceWebClient(HttpHeadersProvider httpHeadersProvider,
                                        ObjectProvider<List<InstanceExchangeFilterFunction>> filtersProvider) throws SSLException {
        List<InstanceExchangeFilterFunction> additionalFilters = filtersProvider.getIfAvailable(Collections::emptyList);
        return InstanceWebClient.builder()
                .defaultRetries(adminServerProperties.getMonitor().getDefaultRetries())
                .retries(adminServerProperties.getMonitor().getRetries())
                .httpHeadersProvider(httpHeadersProvider)
                .webClient(getWebClient())
                .filters(filters -> filters.addAll(additionalFilters))
                .build();
    }

    private WebClient getWebClient() throws SSLException {
        SslContext sslContext = SslContextBuilder
                .forClient()

                }));
        ReactorClientHttpConnector reactorClientHttpConnector = new ReactorClientHttpConnector(httpClient);

        return WebClient.builder().clientConnector(reactorClientHttpConnector).build();
    }
