unable to find valid certification path to requested target 的简单解决办法

在使用httpClient执行Https的URL中出现此错误unable to find valid certification path to requested target 的简单解决办法！！

解决方法，在httpClient执行的之前调用此方法

/**
* Trust every server - dont check for any certificate
*/
public static void trustAllHosts() {
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return new java.security.cert.X509Certificate[] {};
}

public void checkClientTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}

public void checkServerTrusted(X509Certificate[] chain, String authType)
throws CertificateException {
}
}
};

try {
SSLContext sc = SSLContext.getInstance("TLS");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
e.printStackTrace();
}
}
