When trying to use feign-httpclient with Spring-cloud-starter-openfeign, I am getting SSL Handshake exception while the same code works if I don't use feign-httpclient.
I need to use feign-httpclient as I want to use the connection factory.
build.gradle
//on commenting the below dependency the code works fine.
compile('io.github.openfeign:feign-httpclient:9.4.0')
compile('org.springframework.cloud:spring-cloud-starter-openfeign')
Feign Client
@FeignClient(name = "testClient", url = "https://test:9820")
public interface TestClient {
@RequestMapping(method = RequestMethod.POST, value = "/test", consumes = "application/json", produces = "application/json")
TesteDto get(TestRequestDto testRequestDto);
}
Invocation Code:
testClient.get(new TestRequestDto("test"));
application.yml
feign:
client:
config:
default:
connectTimeout: 5000
readTimeout: 5000
loggerLevel: full
httpclient:
maxConnections: 200
maxConnectionsPerRoute: 200
enabled: true
Exception:
javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to
find valid certification path to requested target
What was required was the following configuration:
feign:
httpclient:
disableSslValidation: true
