Spring5WebClient使用SSL

切勿在生产中使用此TrustManagerFactory。它仅用于测试目的，因此非常不安全。

@Bean
public WebClient createWebClient() throws SSLException {
SslContext sslCOntext= SslContextBuilder
.forClient()
.trustManager(InsecureTrustManagerFactory.INSTANCE)
.build();
ClientHttpConnector httpCOnnector= HttpClient.create().secure { t -> t.sslContext(sslContext) }
return WebClient.builder().clientConnector(httpConnector).build();
}


像Spring 5.1.1长相（spring启动2.1.0）移除HttpClientOptions从ReactorClientHttpConnector，所以你不能配置选项在创建实例ReactorClientHttpConnector

现在有效的一种选择是：

val sslCOntext= SslContextBuilder
.forClient()
.trustManager(InsecureTrustManagerFactory.INSTANCE)
.build()
val httpClient = HttpClient.create().secure { t -> t.sslContext(sslContext) }
val webClient = WebClient.builder().clientConnector(ReactorClientHttpConnector(httpClient)).build()


基本上，在创建HttpClient时，我们将配置不安全的 sslContext，然后将该httpClient传递给ReactorClientHttpConnector全局使用。

另一个选项是TcpClient使用不安全的sslContext 进行配置并使用它来创建HttpClient实例，如下所示：

val sslCOntext= SslContextBuilder
.forClient()
.trustManager(InsecureTrustManagerFactory.INSTANCE)
.build()
val tcpClient = TcpClient.create().secure { sslProviderBuilder -> sslProviderBuilder.sslContext(sslContext) }
val httpClient = HttpClient.from(tcpClient)
val webClient = WebClient.builder().clientConnector(ReactorClientHttpConnector(httpClient)).build()
