您可以执行以下查询：

TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
KeyStore truststore = createTrustStore(truststorePath, truststorePassword);

trustManagerFactory.init(truststore);

// Get hold of the default trust manager

X509TrustManager x509Tm = null;
for (TrustManager tm : trustManagerFactory.getTrustManagers()) {
    if (tm instanceof X509TrustManager) {
        x509Tm = (X509TrustManager) tm;
        break;
    }
}


final X509TrustManager finalTm = x509Tm;
X509TrustManager customTm = new X509TrustManager() {
    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return finalTm.getAcceptedIssuers();
    }

    @Override
    public void checkServerTrusted(X509Certificate[] chain,String authType) throws CertificateException {
            finalTm.checkServerTrusted(chain, authType);
