[FIXED] Spring 5 WebClient using ssl

Issue

I'm trying to find examples of WebClient use.

My goal is to use Spring 5 WebClient to query a REST service using https and self signed certificate

Any example?

Solution

See example of use href="https://netty.io/4.0/api/io/netty/handler/ssl/util/InsecureTrustManagerFactory.html" rel="noreferrer">insecure TrustManagerFactory that trusts all X.509 certificates (including self-signed) without any verification. The important note from documentation:

Never use this TrustManagerFactory in production. It is purely for testing purposes, and thus it is very insecure.

@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();
}
