我一直在寻找一些帮助来解决以下问题，我试图通过带有 jks 的 restTemplate 从 java 进行休息调用。我环顾四周，无法弄清楚为什么这不起作用。
所以从我的服务器我有一个带有密码的 crt 和 key 文件。如果我对服务器进行以下 curl 调用，一切正常，它会检索我需要的信息。
curl --key example.key --cert example.crt:certpassword --digest --user user:password https://myhost/user?id={url_encoded_id}
当我尝试通过 Spring 从 java 运行它时，我创建了如下 jks 文件:
keytool -import -file example.crt -alias exampleCA -keystore truststore.jks
openssl pkcs12 -export -in example.crt -inkey example.key -certfile example.crt -name "examplecert" -out keystore.p12
keytool -importkeystore -srckeystore keystore.p12 -srcstoretype pkcs12 -destkeystore keystore.jks -deststoretype JKS
然后我编写了以下 java 代码来使用 jks:
HttpHeaders httpHeaders = new HttpHeaders();
httpHeaders.add("Authorization", basicAuthValueForUser);
httpHeaders.setContentType(MediaType.APPLICATION_JSON);
String keystore = "<path>\\keystore.jks";
String truststore = "<path>\\truststore.jks";
String certPassPhrase = "certpassword";
SSLContext sslContext = SSLContextBuilder
.create()
.loadKeyMaterial(ResourceUtils.getFile(keystore), certPassPhrase.toCharArray(), certPassPhrase.toCharArray())
.loadTrustMaterial(ResourceUtils.getFile(truststore), certPassPhrase.toCharArray())
.build();
HttpClient client = HttpClients.custom()
.setSSLContext(sslContext)
.build();
HttpComponentsClientHttpRequestFactory factory =
new HttpComponentsClientHttpRequestFactory(client);
RestTemplate restTemplate = new RestTemplate(factory);
ResponseEntity<String> exchange = restTemplate.exchange("https://myhost/user?id={url_encoded_id}",
HttpMethod.GET, new HttpEntity<>("", httpHeaders), String.class);
当我尝试运行它时，出现以下错误:

如有任何帮助，我们将不胜感激!
最佳答案
经过更多的测试和研究，我发现我的信任库缺少完成链所需的证书。
我必须打开浏览器，转到 https://myhost ，从服务器下载证书(crt)文件并将其添加到我的 truststore.jks 之后错误被清除，我可以调用电话。
关于java - 需要帮助使用证书文件运行 Spring restTemplate - 无法找到请求目标的有效证书路径，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/48157905/
