Java 使用ApacheHttpClient 4.5和SpringRestTemplate忽略SSL警告

我们有一个内部服务，我们希望开始通过HTTPS进行呼叫。该服务仅在内部提供，因此我不担心接受所有自签名警告。这就是我正在使用的：

    BasicCredentialsProvider credentialsProvider =  new BasicCredentialsProvider();
    credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(REST_USER, REST_PASS));
    SSLContextBuilder builder = new SSLContextBuilder();
    builder.loadTrustMaterial(null, new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            return true;
        }
    });
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build(),
            SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
    CloseableHttpClient client = HttpClients.custom()
            .setDefaultCredentialsProvider(credentialsProvider)
            .setSSLSocketFactory(sslsf)
            .build();
    HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
    requestFactory.setHttpClient(client);
    RestTemplate restTemplate =  new RestTemplate(requestFactory);

但我得到了以下错误：

org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://localhost/addrgeo/standardUSAddresses": sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

我甚至尝试创建了一个

池客户端连接管理器

：

    BasicCredentialsProvider credentialsProvider =  new BasicCredentialsProvider();
credentialsProvider.setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(REST_USER, REST_PASS));

SSLContextBuilder builder = new SSLContextBuilder();
builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build(),SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", new PlainConnectionSocketFactory())
        .register("https", sslsf)
        .build();
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
cm.setMaxTotal(2000);//max connection

CloseableHttpClient httpClient = HttpClients.custom()
        .setDefaultCredentialsProvider(credentialsProvider)
        .setSSLSocketFactory(sslsf)
        .setConnectionManager(cm)
        .build();

HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);

BasicCredentialsProvider凭证提供者=新的BasicCredentialsProvider（）；
setCredentials（AuthScope.ANY，新用户名密码Credentials（REST_USER，REST_PASS））；
SSLContextBuilder=新的SSLContextBuilder（）；
loadTrustMaterial（空，新TrustSelfSignedStrategy（））；
SSLConnectionSocketFactory sslsf=新的SSLConnectionSocketFactory（builder.build（），SSLConnectionSocketFactory.ALLOW\u ALL\u主机名\u验证器）；
Registry Registry=RegistryBuilder.create（）
.register（“http”，新的PlainConnectionSocketFactory（））
.注册（“https”，sslsf）
.build（）；
PoolightPClientConnectionManager cm=新的PoolightPClientConnectionManager（注册表）；
cm.setMaxTotal（2000年）//最大连接
CloseableHttpClient httpClient=HttpClients.custom（）
.setDefaultCredentialsProvider（credentialsProvider）
.setSSLSocketFactory（sslsf）
.setConnectionManager（cm）
.build（）；
HttpComponents客户端HttpRequestFactory requestFactory=新的HttpComponents客户端HttpRequestFactory（）；
setHttpClient（httpClient）；

但我也犯了同样的错误

我们正在用Hystrix来包装我们的呼叫，但我不知道为什么这会对实际呼叫本身产生任何影响

我看了一下这个问题:

但似乎没有一个答案能让我达到我需要的地方

我做错了什么

解决方案 我觉得自己像个傻瓜

结果是IntelliJ出现了一个奇怪的缓存问题。Maven仍在使用旧的源代码。解决方案是关闭IntelliJ，运行

mvn清洁安装

，打开IntelliJ中的缓存并使其失效，然后重新导入项目。为了更好地衡量，我还刷新了

VCS

下的文件状态，并执行了同步
