使用带有自签名证书的 Spring RestTemplate 时如何修复 "SSLHandshakeException"
How to fix "SSLHandshakeException" while using Spring RestTemplate with a self-signed certificate
我正在尝试使用 Spring 的 RestTemplate 通过 Java 客户端调用 REST Api（https，使用自签名证书保护）。当我尝试使用 Postman 时，它是成功的。我有一个crt文件和一个私钥文件。我在 Postman settings/certificates 中定义它们并且请求成功。但是当我尝试使用 Java 代码时，我得到 SSLHandshakeException。
我正在使用 Java 11 和 Spring Boot。我使用 keytool 创建了一个 .jks 文件并将其放在类路径中。我使用的keytool命令是：
keytool -import -alias alias -file blahblah.crt -keypass keypass -keystore mykeystore.jks -storepass mystorepass
(我估计不能直接使用.crt证书文件，所以我创建了一个.jks文件)
然后我运行下面的代码：
URL storeUrl = new URL("classpath:mykeystore.jks");
SSLContext sslContext = new SSLContextBuilder()
.setProtocol("TLSv1.2")
.loadTrustMaterial(new TrustSelfSignedStrategy())
.loadKeyMaterial(storeUrl, trustStorePassword.toCharArray(), keyPassword.toCharArray())
.build();
SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(sslContext);
HttpClient httpClient = HttpClients.custom()
.setSSLSocketFactory(socketFactory)
.build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
restTemplate = new RestTemplate(factory);
//...
restTemplate.postForObject(myUri, new HttpEntity<>(json, httpHeaders), String.class);

我已经尝试解决这个问题 2 天了，但仍然找不到解决方案。有什么我看不到的，或者是否有可能了解握手失败的原因？非常感谢。
我会回答我自己的问题：是的，我们需要从 .crt 文件创建一个 .jks 文件。然后 Java 代码是：
try {
RestTemplate restTemplate = new RestTemplate();
KeyStore keyStore = KeyStore.getInstance("jks");
File keyFile = new File(KEY_STORE_FILE);
FileSystemResource fileSystemResource = new FileSystemResource(keyFile);
InputStream inputStream = fileSystemResource.getInputStream();
keyStore.load(inputStream,
Objects.requireNonNull(KEY_STORE_PASS).toCharArray());
SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(new SSLContextBuilder()
.loadTrustMaterial(null, new TrustSelfSignedStrategy())
.loadKeyMaterial(keyStore,
KEY_PASS.toCharArray()).build(),
NoopHostnameVerifier.INSTANCE);
HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory)
.build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);
restTemplate.setRequestFactory(requestFactory);
return restTemplate;
} catch (Exception e) {
logger.debug("SSL keystore exception", e);
throw new BlahBlahException(e);
}

我已经尝试解决这个问题 2 天了，但仍然找不到解决方案。有什么我看不到的，或者是否有可能了解握手失败的原因？非常感谢。
我会回答我自己的问题：是的，我们需要从 .crt 文件创建一个 .jks 文件。然后 Java 代码是：
try {
RestTemplate restTemplate = new RestTemplate();
KeyStore keyStore = KeyStore.getInstance("jks");
File keyFile = new File(KEY_STORE_FILE);
FileSystemResource fileSystemResource = new FileSystemResource(keyFile);
InputStream inputStream = fileSystemResource.getInputStream();
keyStore.load(inputStream,
Objects.requireNonNull(KEY_STORE_PASS).toCharArray());
SSLConnectionSocketFactory socketFactory = new SSLConnectionSocketFactory(new SSLContextBuilder()
.loadTrustMaterial(null, new TrustSelfSignedStrategy())
.loadKeyMaterial(keyStore,
KEY_PASS.toCharArray()).build(),
NoopHostnameVerifier.INSTANCE);
HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(socketFactory)
.build();
HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient);
restTemplate.setRequestFactory(requestFactory);
return restTemplate;
} catch (Exception e) {
logger.debug("SSL keystore exception", e);
throw new BlahBlahException(e);
}
