JGit代碼

Question

代理配置，我能夠在JGit使用clone命令來克隆回購

回購是http，當然它的失敗

你能幫助我的代碼示例如何克隆當我身後代理

在java中使用代理配置JGit

謝謝！

JGit使用標準ProxySelector機制進行Http連接。 截至今日，該框架使用的字段org.eclipse.jgit.transport.TransportHttp.proxySelector不可覆蓋。它是可配置的，不過，定製JVM默認代理選擇，如：

ProxySelector.setDefault(new ProxySelector() { 
    final ProxySelector delegate = ProxySelector.getDefault(); 

    @Override 
    public List<Proxy> select(URI uri) { 
      // Filter the URIs to be proxied 
     if (uri.toString().contains("github") 
       && uri.toString().contains("https")) { 
      return Arrays.asList(new Proxy(Type.HTTP, InetSocketAddress 
        .createUnresolved("localhost", 3128))); 
     } 
     if (uri.toString().contains("github") 
       && uri.toString().contains("http")) { 
      return Arrays.asList(new Proxy(Type.HTTP, InetSocketAddress 
        .createUnresolved("localhost", 3129))); 
     } 
      // revert to the default behaviour 
     return delegate == null ? Arrays.asList(Proxy.NO_PROXY) 
       : delegate.select(uri); 
    } 

    @Override 
    public void connectFailed(URI uri, SocketAddress sa, IOException ioe) { 
     if (uri == null || sa == null || ioe == null) { 
      throw new IllegalArgumentException(
        "Arguments can't be null."); 
     } 
    } 
});

在卡羅佩萊格里尼回答的補充，如果你的代理服務器需要一些認證，你應該配置一個Authenticator，像（基於Authenticated HTTP proxy with Java問題）：

Authenticator.setDefault(new Authenticator() { 
     @Override 
     public PasswordAuthentication getPasswordAuthentication() { 
      // If proxy is non authenticated for some URLs, the requested URL is the endpoint (and not the proxy host) 
      // In this case the authentication should not be the one of proxy ... so return null (and JGit CredentialsProvider will be used) 
      if (super.getRequestingHost().equals("localhost")) { 
       return new PasswordAuthentication("foo", "bar".toCharArray()); 
      } 
      return null; 
     } 
    }); 

    ProxySelector.setDefault(new ProxySelector() {...});
