java调用https接口报错详解编程语言

调用第三方https接口，在本地测试没问题，将项目提交到测试环境怎么都掉不通，报如下错误：

查了下大概就是说没证书，本地是在chrome浏览器上测试的，测试过程中一直没提示说要安装什么证书，也看了下本地的证书，……东西太多，一下子找不出到底本地在不知道的情况下安装了哪个证书，网上查了很多资料，有说在服务器上安装证书的，有说改代码的，最后解决的办法是创建CloseableHttpClient用了以下代码，https接口成功调用：

public static CloseableHttpClient createSSLClientDefault(){ 
        try { 
            SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() { 
                //信任所有 
                public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException { 
                    return true; 
                } 
            }).build(); 
            SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext); 
            return HttpClients.custom().setSSLSocketFactory(sslsf).build(); 
        } catch (KeyManagementException e) { 
            e.printStackTrace(); 
        } catch (NoSuchAlgorithmException e) { 
            e.printStackTrace(); 
        } catch (KeyStoreException e) { 
            e.printStackTrace(); 
        } 
        return  HttpClients.createDefault(); 
    }
