在春天的resttemplate发出的每个请求发送客户端证书的正确方法是什么？

Question

我想用我的spring应用程序使用REST服务.要访问该服务,我有一个客户端证书(自签名和.jks格式)进行授权.对其他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());
}

Answer 1

以下是使用RestTemplate和Apache HttpClient执行此操作的示例

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,将使用此模板执行的所有远程调用cert.jks. 注意:您需要放入cert.jks类路径

@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());
}
