我像这样使用RestTemplate配置：
private RestTemplate createRestTemplate() throws Exception {
final String username = "admin";
final String password = "admin";
final String proxyUrl = "localhost";
final int port = 443;
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(proxyUrl, port),
new UsernamePasswordCredentials(username, password));
HttpHost host = new HttpHost(proxyUrl, port, "https");
HttpClientBuilder clientBuilder = HttpClientBuilder.create();
clientBuilder.setProxy(host).setDefaultCredentialsProvider(credsProvider).disableCookieManagement();
HttpClient httpClient = clientBuilder.build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
factory.setHttpClient(httpClient);
return new RestTemplate(factory);
}
这就是我的方法的工作方式：
public String receiveMessage(String message) {
try {
restTemplate = createRestTemplate();
ObjectMapper mapper = new ObjectMapper();
Class1 class1 = null;
String json2 = "";
class1= mapper.readValue(message, Class1.class);
Class1 class2 = restTemplate.getForObject(URL_SERVICE_1 + "/class1/findByName?name=" + class1.getName(),
Class1.class);
System.out.println("Server 1 : " + message);
json2 = mapper.writeValueAsString(class2);
return "Error - " + json2;
} catch (Exception e) {
// TODO Auto-generated catch block
return e.getMessage();
}
}
URL_SERVICE_1包含https://localhost
当我尝试调用函数GET时，我总是这样返回：
I/O error on GET request for "https://localhost/class1/findByName?name=20-1P": Host name 'localhost' does not match the certificate subject provided by the peer (CN=*.webku-cool.com, OU=EssentialSSL Wildcard, OU=Domain Control Validated); nested exception is javax.net.ssl.SSLPeerUnverifiedException: Host name 'localhost' does not match the certificate subject provided by the peer (CN=*.webku-cool.com, OU=EssentialSSL Wildcard, OU=Domain Control Validated)
我不知道https使用restTemplate的正确设置。我已经尝试了23个关于SSL设置的引用并得到了相同的错误。

由于已接受的答案已弃用代码，因此我发现这有用：
SSLContextBuilder sslcontext = new SSLContextBuilder();
sslcontext.loadTrustMaterial(null, new TrustSelfSignedStrategy());
httpclient = HttpAsyncClients.custom().setSSLContext(sslcontext.build()).setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
.build();

此问题的正确解决方法是通过将localhost添加到主题列表来更正ssl证书。但是，如果您的目的是绕过ssl进行开发，则需要定义一个连接工厂，它始终将主机名验证的结果返回为true。
<强> SSLClientHttpRequestFactory
public class SSLClientHttpRequestFactory extends SimpleClientHttpRequestFactory {
@Override
protected void prepareConnection(HttpURLConnection connection, String httpMethod) {
try {
if (!(connection instanceof HttpsURLConnection)) {
throw new RuntimeException("An instance of HttpsURLConnection is expected");
}
HttpsURLConnection httpsConnection = (HttpsURLConnection) connection;
TrustManager[] trustAllCerts = new TrustManager[] { new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(X509Certificate[] certs, String authType) {
}
} };
SSLContext sslContext = SSLContext.getInstance("TLS");
sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
httpsConnection.setSSLSocketFactory(new MyCustomSSLSocketFactory(sslContext.getSocketFactory()));
httpsConnection.setHostnameVerifier(new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
super.prepareConnection(httpsConnection, httpMethod);
} catch (Exception e) {
e.printStackTrace();
}
}

if (!(socket instanceof SSLSocket)) {
throw new RuntimeException("An instance of SSLSocket is expected");
}
((SSLSocket) socket).setEnabledProtocols(new String[] { "TLSv1" });
return socket;
}
}
}使用上面提到的连接工厂作为RestTemplate的构造函数参数。覆盖主机名验证以始终返回true的代码部分如下：
httpsConnection.setHostnameVerifier(new HostnameVerifier() {
public boolean verify(String hostname, SSLSession session) {
return true;
}
});
快乐的编码！

在从网上尝试了很多不同的选项之后，这个选项对我有用...非常感谢...
SSLContextBuilder sslcontext = new SSLContextBuilder();
sslcontext.loadTrustMaterial(null, new TrustSelfSignedStrategy());
HttpClient httpClient = HttpAsyncClients.custom().setSSLContext(sslcontext.build()).setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
.build();

这就是我的工作方式： 1.此bean忽略SSL检查 2.它也忽略证书不匹配
@Bean
public RestTemplate restTemplate()
throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;
SSLContextBuilder sslcontext = new SSLContextBuilder();
sslcontext.loadTrustMaterial(null, new TrustSelfSignedStrategy());
SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
.loadTrustMaterial(null, acceptingTrustStrategy)
.build();
SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);
CloseableHttpClient httpClient = HttpClients.custom().setSSLContext(sslcontext.build()).setSSLHostnameVerifier(
NoopHostnameVerifier.INSTANCE)
.build();
HttpComponentsClientHttpRequestFactory requestFactory =
new HttpComponentsClientHttpRequestFactory();
requestFactory.setHttpClient(httpClient);
RestTemplate restTemplate = new RestTemplate(requestFactory);
return restTemplate;
}
