在春季，resttemplate发出的每个请求都发送客户证书的正确方法是什么？

问题内容：

我想在我的spring应用程序中使用REST服务。要访问该服务，我需要获得客户端证书（自行签名并以.jks格式）。对其余服务进行身份验证的正确方法是什么？

这是我的要求：

public List<Info> getInfo() throws RestClientException, URISyntaxException {

    HttpEntity<?> httpEntity = new HttpEntity<>(null, new HttpHeaders());

    ResponseEntity<Info[]> resp = restOperations.exchange(
            new URI(BASE_URL + "/Info"), HttpMethod.GET, 
            httpEntity, Info[].class);
    return Arrays.asList(resp.getBody());
}

问题答案：

这是使用RestTemplate和Apache
HttpClient的
方法示例

您应该RestTemplate使用配置的SSL上下文定义自己的：

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) throws Exception {
    char[] password = "password".toCharArray();

    SSLContext sslContext = SSLContextBuilder.create()
            .loadKeyMaterial(keyStore("classpath:cert.jks", password), password)
            .loadTrustMaterial(null, new TrustSelfSignedStrategy()).build();

    HttpClient client = HttpClients.custom().setSSLContext(sslContext).build();
    return builder
            .requestFactory(new HttpComponentsClientHttpRequestFactory(client))
            .build();
}

 private KeyStore keyStore(String file, char[] password) throws Exception {
    KeyStore keyStore = KeyStore.getInstance("PKCS12");
    File key = ResourceUtils.getFile(file);
    try (InputStream in = new FileInputStream(key)) {
        keyStore.load(in, password);
    }
    return keyStore;
}

现在，此模板执行的所有远程呼叫将使用签名cert.jks。 注意 ：您需要将其cert.jks放入类路径中

@Autowired
private RestTemplate restTemplate;

public List<Info> getInfo() throws RestClientException, URISyntaxException {
    HttpEntity<?> httpEntity = new HttpEntity<>(null, new HttpHeaders());

    ResponseEntity<Info[]> resp = restTemplate.exchange(
            new URI(BASE_URL + "/Info"), HttpMethod.GET, 
            httpEntity, Info[].class);
    return Arrays.asList(resp.getBody());
}
