javax.net.ssl.SSLHandshakeException：sun.security.validator.ValidatorException：PKIX路径构建失败

问题描述

我正在使用java应用程序检查url connrectivity，对于某些url（内部）应用程序url，我得到200（成功），对于其他人我得到以下异常。

i am using java application to check the url connrectivity, for the some url (internal) application url, i am getting 200 (success), for the others i am getting the below exception.

但如果我手动连接到以下网址，没有问题，我需要pki证书。
需要你的帮助。

but if i manually connect to the below url , no issues on that, do i need pki certificates.need your help.

200 OK OK

推荐答案

Java不信任SSL证书。证书可以是自签名的，也可以由其根证书不在Java证书库中的CA（证书颁发机构）签名。

The SSL certificate isn't trusted by Java. The certificate may be self-signed, or it may be signed by a CA (Certificate Authority) whose root certificate is not in the Java certificate store.

添加代码以信任主机提供的证书。在使用URL之前导入证书。

Add the code to trust the certificate provided by host. Import the certificate before consuming the URL.

只需添加以下代码即可信任证书

Just add below code to trust the certificate

TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
        return null;
    }
    public void checkClientTrusted(
        java.security.cert.X509Certificate[] certs, String authType) {
    }
    public void checkServerTrusted(
        java.security.cert.X509Certificate[] certs, String authType) {
    }
}};

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

// Add your code below
