通常如果rest服務(wù)支持https，需申請收費(fèi)的ssl證書，但也可自制這種證書。
httpClient進(jìn)行鏈接時要進(jìn)行相應(yīng)的設(shè)置， 主要是設(shè)置SSLContext中的
TrustSelfSignedStrategy：
import java.security.KeyManagementException;
import java.security.KeyStoreException;
import java.security.NoSuchAlgorithmException;
import java.util.concurrent.TimeUnit;
import javax.net.ssl.SSLContext;
import org.apache.http.client.config.RequestConfig;
import org.apache.http.conn.ssl.TrustSelfSignedStrategy;
import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.conn.PoolingHttpClientConnectionManager;
import org.apache.http.ssl.SSLContexts;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

result.setMaxTotal(200);
result.setDefaultMaxPerRoute(20);
return result;
}
@Bean
public RequestConfig requestConfig(AbstractProperties kycProperties) {

}
@Bean

相應(yīng)設(shè)置
