错误Java连接使用SSL证书的HTTPS

问题描述：

我在使用Java连接SSL时遇到问题。错误Java连接使用SSL证书的HTTPS

我使用java 1.7.80和S.O. ：ubuntu 14.04

我的问题是证书，甚至证书。我有四个元素必须使用pkcs12格式连接。

testservizi.fattura.it.cer - 标识该远程服务器>证书

SDI-11036210158 - >客户端证书的

CAEntratetest.cer - >证书CA

private.key - >私钥

1）步骤 - 将文件cer转换为文件pem

$ openssl x509 -in CAEntratetest.cer -outform PEM -out CAEntratetest.pem 
$ openssl x509 -in SDI-11036210158.cer -inform DER -out SDI-11036210158.pem -outform PEM 
$ openssl x509 -in testservizi.fatturapa.it.cer -inform DER -out testservizi.fatturapa.it.pem -outform PEM

2）步骤 - 联合PEM文件创建链证书

$ cat CAEntratetest.pem SDI-11036210158.pem testservizi.fatturapa.it.pem > sum_cert.pem

3）步骤 - 创建P12文件

$ openssl pkcs12 -export -in sum_cert.pem -inkey private.key -out sogei_auth.p12 -name sogei_auth

确定。我的第一个测试是在浏览器（Mozilla Firefox）中导入p12文件以验证操作。导入成功，在这一点上我输入网址

https://testservizi.fatturapa.it/ricevi_file

您好！这是一个Axis2 Web服务！

..完美的作品！

现在我必须使它与Java工作，我创建一个测试客户端

import java.io.File; 
import javax.net.ssl.SSLContext; 
import org.apache.http.HttpEntity; 
import org.apache.http.client.methods.CloseableHttpResponse; 
import org.apache.http.client.methods.HttpGet; 
import org.apache.http.conn.ssl.SSLConnectionSocketFactory; 
import org.apache.http.impl.client.CloseableHttpClient; 
import org.apache.http.impl.client.HttpClients; 
import org.apache.http.ssl.SSLContexts; 
import org.apache.http.util.EntityUtils; 

public class TestHTTPSClient { 

    public static void main(String[] args) throws Exception { 
     SSLContext sslcontext = SSLContexts.custom().loadTrustMaterial(new File("C:/testSSL/sogei_auth.p12"), "changeit".toCharArray()).build(); 
     SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext); 
     CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build(); 
     try { 
      HttpGet httpget = new HttpGet("https://testservizi.fatturapa.it/ricevi_file"); 
      System.out.println("executing request " + httpget.getRequestLine()); 
      CloseableHttpResponse response = httpclient.execute(httpget); 
      try { 
       HttpEntity entity = response.getEntity(); 
       System.out.println("----------------------------------------"); 
       System.out.println(response.getStatusLine()); 
       EntityUtils.consume(entity); 
      } finally { 
       response.close(); 
      } 
     } finally { 
      httpclient.close(); 
     } 
    } 
}

2）更改格式密钥存储在java.security，否则您无法读取该文件P12

keystore.type=jks

变化成

keystore.type=pkcs12

3）启动在Java测试，我回答了一个错误

Exception in thread "main" 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 
...

你可以帮我...

答

您可以在JRE cacerts文件存储永久解决此问题，如果运行时认证的东西不需要！检查this安装证书给cacerts的答案...

并从您的源代码中删除所有与认证相关的代码！请澄清，如果你想只做这个运行时间而不是手动。
