将java类转换为groovy：Groovy：数组构造函数调用没有表达式

Question

出于测试目的，我想尝试使用下面的 java 类。但我需要将它移植到groovy。

java类：

public class HttpsTrustManager implements X509TrustManager {
    private static TrustManager[] trustManagers;
    private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};

    @Override
    public void checkClientTrusted(
            X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {

    }

    @Override
    public void checkServerTrusted(
            X509Certificate[] x509Certificates, String s)
            throws java.security.cert.CertificateException {

    }

    public boolean isClientTrusted(X509Certificate[] chain) {
        return true;
    }

    public boolean isServerTrusted(X509Certificate[] chain) {
        return true;
    }

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return _AcceptedIssuers;
    }

    public static void allowAllSSL() {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {

            @Override
            public boolean verify(String arg0, SSLSession arg1) {
                return true;
            }

        });

        SSLContext context = null;
        if (trustManagers == null) {
            trustManagers = new TrustManager[]{new HttpsTrustManager()};
        }

        try {
            context = SSLContext.getInstance("TLS");
            context.init(null, trustManagers, new SecureRandom());
        } catch (NoSuchAlgorithmException | KeyManagementException e) {
            e.printStackTrace();
        }

        HttpsURLConnection.setDefaultSSLSocketFactory(context != null ? context.getSocketFactory() : null);
    }
}

当我将其移动到 .groovy 文件时，我在这一行收到以下错误：

private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[]{};

错误：

Groovy:No expression for the array constructor call at line:

还有这一行：

if (trustManagers == null) {
    trustManagers = new TrustManager[]{new HttpsTrustManager()}; 
}

错误：

Groovy:No expression for the array constructor call at line:

我这样移植的第一行：

  private static final X509Certificate[] _AcceptedIssuers = [ new X509Certificate(){} ] as X509Certificate[]

但不能 100% 确定其正确性。但我在第二行仍然有错误：

    trustManagers = new TrustManager[]{new HttpsTrustManager()};

有任何想法吗？

我们不能在 Groovy 中使用 Java 数组初始化语法。

所以

private static final X509Certificate[] _AcceptedIssuers = [ new X509Certificate(){} ] as X509Certificate[]

是正确的，你还需要改变

trustManagers = new TrustManager[]{new HttpsTrustManager()};

到

trustManagers = [new HttpsTrustManager()] as TrustManager[];
