尝试在Java中使用Apache HttpClient执行GET时出错

我正在尝试编写一个Java代码，需要使用ApacheHttpClient从RESTfulAPI获取数据。 我的web服务器具有自签名证书。我使用的代码如下：

public class WebClientDevWrapper {

    public static HttpClient wrapClient(HttpClient base) {
        try {
            ClientConnectionManager ccm = base.getConnectionManager();
            SSLSocketFactory sslsf = new SSLSocketFactory(new TrustSelfSignedStrategy());
            Scheme https = new Scheme("https", 444, sslsf);
            ccm.getSchemeRegistry().register(https);
            return new DefaultHttpClient(ccm, base.getParams());
        } catch (Exception ex) {
            ex.printStackTrace();
            return null;
        }
    }
    public static void main(String[] args) throws ClientProtocolException, IOException{
        HttpClient client ;
        client = new DefaultHttpClient();
        client = WebClientDevWrapper.wrapClient(client);
        HttpGet request = new HttpGet("https://localhost/restapi");
        HttpResponse response = client.execute(request);
        BufferedReader rd = new BufferedReader (new InputStreamReader(response.getEntity().getContent()));
        String line = "";
        while ((line = rd.readLine()) != null) {
          System.out.println(line);
        }
    }
}

运行此代码时，我遇到以下错误： “javax.net.ssl.SSLException:的证书不包含CN或DNS subjectAlt”

请提供帮助。

您需要在JAVA中导入SSL证书。使用下面的行

\bin\keytool-import-v-trustcacerts
-别名[您的别名]-文件[您的证书位置]
-密钥库[密钥库位置]-密钥传递[您的密码]
-storepass[您的密码]

CN代表“通用名”您确定用名称生成了您的证书吗？您是否使用keytool.exe导入了证书？它是否在您的jdk\jre\lib\security\cacerts路径下？然后，您是否使用-Djavax.net.ssl.trustStore JVM参数提供了证书路径？
