How to use ssl certificate with feign? Know the answer here – To use an SSL certificate with Feign, you can configure your Feign client with an SSLSocketFactory
that trusts the SSL certificate. You can do this by creating an OkHttpClient
with an X509TrustManager
that trusts the SSL certificate and then passing this client to the Feign builder:
X509TrustManager trustManager = ...; // Create trust manager that trusts the SSL certificate
SSLSocketFactory sslSocketFactory = new SSLSocketFactoryCompat(trustManager);
OkHttpClient client = new OkHttpClient.Builder()
.sslSocketFactory(sslSocketFactory, trustManager)
.build();
GitHub github = Feign.builder()
.client(new OkHttpClient(client))
.target(GitHub.class, "https://api.github.com");
Alternatively, you can also use a Client.Default
instance with the OkHttpClient
as the delegate:
GitHub github = Feign.builder()
.client(new Client.Default(client, null))
.target(GitHub.class, "https://api.github.com");
Here, GitHub
is the interface defining the Feign client and https://api.github.com
is the base URL of the API being called. With these configurations in place, the Feign client will use the provided SSLSocketFactory
and trust the SSL certificate when making requests to the API.
