这看起来是一个标准问题，但我在任何地方都找不到明确的方向。
我有java代码试图连接到一个可能自签名(或过期)证书的服务器。代码报告以下错误:
[HttpMethodDirector] I/O exception (javax.net.ssl.SSLHandshakeException) caught
when processing request: sun.security.validator.ValidatorException: PKIX path
building failed: sun.security.provider.certpath.SunCertPathBuilderException:
unable to find valid certification path to requested target
根据我的理解，我必须使用keytool并告诉java允许此连接是OK的。
解决此问题的所有说明都假设我完全熟练使用keytool，例如
为服务器生成私有密钥并将其导入密钥存储库
有人能给我详细说明吗?
我正在运行unix，所以bash脚本将是最好的。
不确定这是否重要，但在jboss中执行的代码。
您可以通过在RestTemplate级别禁用它来实现这一点。
注意，此TrustStrategy将信任所有证书，并且使用NoopHostnameVerifier()禁用了主机名验证。
public RestTemplate getRestTemplate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
TrustStrategy acceptingTrustStrategy = (x509Certificates, s) -> true;
SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext, new NoopHostnameVerifier());
CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(csf).build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
return new RestTemplate(requestFactory);
}

Apache HttpClient 4.5支持接受自签名证书:
SSLContext sslContext = SSLContexts.custom()
.loadTrustMaterial(new TrustSelfSignedStrategy())
.build();
SSLConnectionSocketFactory socketFactory =
new SSLConnectionSocketFactory(sslContext);
Registry<ConnectionSocketFactory> reg =
RegistryBuilder.<ConnectionSocketFactory>create()
.register("https", socketFactory)
.build();
HttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(reg);
CloseableHttpClient httpClient = HttpClients.custom()
.setConnectionManager(cm)
.build();
HttpGet httpGet = new HttpGet(url);
CloseableHttpResponse sslResponse = httpClient.execute(httpGet);
这将构建一个SSL套接字工厂，它将使用TrustSelfSignedStrategy，将其注册到自定义连接管理器，然后使用该连接管理器执行HTTP GET。
我同意那些高呼“不要在生产环境中这样做”的人，但是在生产环境之外接受自签名证书是有用例的;我们在自动化集成测试中使用它们，因此即使不在生产硬件上运行，我们也在使用SSL(就像在生产中一样)。
信任所有SSL证书:—
如果希望在测试服务器上进行测试，可以绕过SSL。
但是不要将此代码用于生产。
public static class NukeSSLCerts {
protected static final String TAG = "NukeSSLCerts";
public static void nuke() {
try {
TrustManager[] trustAllCerts = new TrustManager[] {
new X509TrustManager() {
public X509Certificate[] getAcceptedIssuers() {
X509Certificate[] myTrustedAnchors = new X509Certificate[0];
return myTrustedAnchors;
}
@Override
public void checkClientTrusted(X509Certificate[] certs, String authType) {}
@Override
public void checkServerTrusted(X509Certificate[] certs, String authType) {}
}
};
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
@Override
public boolean verify(String arg0, SSLSession arg1) {
return true;
}
});
} catch (Exception e) {
}
}
}
请在Activity或应用程序类的onCreate()函数中调用此函数。
NukeSSLCerts.nuke();
这可以用于Android的Volley。
