找不到请求目标的有效证书路径-java

我正在尝试使用对象连接到网站。它适用于我们通常使用的网站（如谷歌）。但是有一个网站，当我尝试连接时，我的程序会给出这个错误

当我尝试从浏览器转到此url时，我必须单击“继续”。否则，浏览器将不会加载该页面。它给出了一个隐私错误说你的连接不是私有的

---

如何在java应用程序中克服这个问题。。？我希望我的软件与该url连接时不会出现任何错误，也不会要求任何确认。

当我使用对象作为信任材料时，问题得到了解决

---

我使用的代码如上图所示。

对于HttpClient4.x，以下代码将信任所有

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);
}

这回答了你的问题吗？什么是链和授权类型？

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);
}
