java - trustStore路径找不到可信证书错误

所以我试图从我的Java代码访问HTTPS服务器，但由于我的localhost和服务器之间的SSL握手问题，我无法使用 . 我尝试访问的服务器具有从私有证书颁发机构颁发的有效证书 .

因此，经过一些研究，我将CA根证书导入JVM信任库 . 我使用keytool命令将证书导入JRE . keytool -import -alias mycertificate -keystore .. \ lib \ security \ cacerts -file c：\ mycert.cer

public static void main (String[]args)  {

try {

        // Open a secure connection.
        URL url = new URL("*****");

        HttpsURLConnection con = (HttpsURLConnection)url.openConnection();
        // Set up the connection properties
        con.setRequestProperty( "Connection", "close" );
        con.setDoInput(true);
        con.setDoOutput(true);
        con.setUseCaches(false);
        con.setConnectTimeout( 30000 );
        con.setReadTimeout( 30000 );

        con.setRequestProperty("Accept","application/json");

         con.setRequestProperty( "Content-Type","application/x-www-form- urlencoded");
        con.setRequestMethod("POST");




        // Set up the user authentication portion of the handshake with    the private




        File pKeyFile = new File("C:/cert.p12");
        String pKeyPassword = "xxxx";
        TrustManagerFactory tmf=     TrustManagerFactory.getInstance("SunX509");
        KeyStore keyStore = KeyStore.getInstance("PKCS12");

        InputStream keyInput = new FileInputStream(pKeyFile);
        keyStore.load(keyInput, pKeyPassword.toCharArray());
        keyInput.close();
        tmf.init(keyStore);


 SSLContext context = SSLContext.getInstance("SSL");

 context.init(null,  tmf.getTrustManagers(), new SecureRandom());

        SSLSocketFactory sockFact = context.getSocketFactory();
        con.setSSLSocketFactory( sockFact );


        // Send the request
        OutputStream outputStream = con.getOutputStream();
        OutputStreamWriter osw = new OutputStreamWriter(outputStream, "UTF-8");
        osw.write("grant_type=client_credentials&scope=sc0:fal");
        osw.flush();
        osw.close();

        // Check for errors
        int responseCode = con.getResponseCode();
        System.out.println("POST Response Code :: " + responseCode);


        InputStream inputStream;
        if (responseCode == HttpURLConnection.HTTP_OK) {
            //success
            inputStream = con.getInputStream();
        } else {
            inputStream = con.getErrorStream();
        }

        // Process the response
        BufferedReader reader;
        String line = null;
        reader = new BufferedReader( new InputStreamReader( inputStream ) );
        while( ( line = reader.readLine() ) != null )
        {
            System.out.println( line );
            //reader.append(line);
        }

        inputStream.close();
    } catch (Exception e) { e.printStackTrace(); }











    }
