当我使用TrustSelfSignedStrategy对象作为HttpClient的信任材料时问题得以解决。

        httpClient = HttpClients.custom()
            .setSSLSocketFactory(new SSLConnectionSocketFactory(SSLContexts.custom()
                    .loadTrustMaterial(null, new TrustSelfSignedStrategy())
                    .build()
                )
            ).build();

我使用的代码如上所示..

对于HttpClient4.x，以下内容将信任所有

public static HttpClientBuilder createTrustAllHttpClientBuilder() {
  SSLContextBuilder builder = new SSLContextBuilder();
  builder.loadTrustMaterial(null, (chain, authType) -> true);           
  SSLConnectionSocketFactory sslsf = new 
  SSLConnectionSocketFactory(builder.build(), NoopHostnameVerifier.INSTANCE);
  return HttpClients.custom().setSSLSocketFactory(sslsf);
}
