I am using Spring Boot, Spring MVC and Spring Web with HttpClient. While trying to create HttpClient object in @Configuration class I get exception for following code:
SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
.register("http", PlainConnectionSocketFactory.getSocketFactory())
.register("https", sslSocketFactory)
.build();
POM dependencies
<properties>
<http.client>4.5.2</http.client>
<http.core>4.4.4</http.core>
</<properties>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpcore</artifactId>
<version>${http.core}</version>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>${http.client}</version>
</dependency>

I had faced similar kind of issue. An old httpClient jar was loaded first. After replacing that jar, it's working fine.
java.lang.NoSuchMethodError: org.apache.http.conn.ssl.SSLConnectionSocketFactory.(Ljavax/net/ssl/SSLContext;Ljavax/net/ssl/HostnameVerifier;)V

I was able to find the source of the library collision using this source:
"That's odd, maybe it's loading the Apache classes from a different jar. Can you try running the following and pasting the output? It may give us a clue where it's trying to get those classes from: org.apache.http.conn.ssl.SSLConnectionSocketFactory.class.getProtectionDomain().getCodeSource().getLocation().getPath()"
Once I found the location, it turned out to be another jar file in my /.m2/repository/ folder and then I cleaned up that folder so now it refers to the /org/apache/httpcomponents/httpclient/4.5.6/httpclient-4.5.6.jar jar.

Remove the explicit httpcore
dependency (it will be included with httpclient
) and do mvn clean install
. If the problem persists, show your complete POM as you might have a conflicting version of httpclient
installed with something else.
