restTemplate忽略ssl证书

好的，您的问题是关于restTemplate忽略SSL证书。是的，可以通过以下代码让restTemplate忽略SSL证书：

RestTemplate restTemplate = new RestTemplate();

// 忽略SSL证书
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory(HttpClientBuilder.create().setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, (certificate, authType) -> true).build()).build()));

需要注意的是，忽略SSL证书会降低网络通信的安全性，建议只在测试环境下使用。

resttemplate 无视ssl证书

要使RestTemplate忽略SSL证书，你可以创建一个自定义的SimpleClientHttpRequestFactory，并覆盖其createRequest方法。在这个方法中，你可以使用自定义的SSLContext和HostnameVerifier来创建HttpsURLConnection，并绕过证书验证。以下是一个示例代码：

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;
import javax.net.ssl.HostnameVerifier;
import javax.net.ssl.HttpsURLConnection;
import javax.net.ssl.SSLContext;
import javax.net.ssl.SSLSession;
import javax.net.ssl.SSLSocketFactory;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

public class SSL extends SimpleClientHttpRequestFactory {
    
    @Override
    protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
        if (connection instanceof HttpsURLConnection) {
            // Create a custom SSLContext that trusts all certificates
            SSLContext sslContext;
            try {
                sslContext = SSLContext.getInstance("TLS");
                sslContext.init(null, new TrustManager[] { new X509TrustManager() {
                    @Override
                    public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {}

                    @Override
                    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {}

                    @Override
                    public X509Certificate[] getAcceptedIssuers() { return null; }
                }}, null);
            } catch (Exception e) {
                throw new IOException("Failed to create SSLContext", e);
            }

            SSLSocketFactory socketFactory = sslContext.getSocketFactory();
            ((HttpsURLConnection) connection).setSSLSocketFactory(socketFactory);

            // Bypass hostname verification
            ((HttpsURLConnection) connection).setHostnameVerifier(new HostnameVerifier() {
                @Override
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            });
        }

        super.prepareConnection(connection, httpMethod);
    }
}

// 使用自定义的SSL类创建RestTemplate
RestTemplate restTemplate = new RestTemplate(new SSL());

// 现在，你可以使用这个RestTemplate进行无视SSL证书的请求了

通过使用这个自定义的SSL类创建RestTemplate，你可以使其忽略SSL证书验证，并且可以安全地发送请求。请注意，这样做会增加潜在的安全风险，因为它不验证服务器的身份。所以在生产环境中使用时需谨慎。

restTemplate.exchange忽略ssl证书

对于使用 RestTemplate 发起 HTTPS 请求时忽略 SSL 证书验证，你可以通过创建自定义的 HttpClient 来实现。下面是一个示例：

import org.springframework.http.HttpMethod;
import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
import org.springframework.web.client.RequestCallback;
import org.springframework.web.client.ResponseExtractor;
import org.springframework.web.client.RestTemplate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class SSLIgnoreRestTemplate extends RestTemplate {
    
    public SSLIgnoreRestTemplate() {
        super();
        initialize();
    }

    public SSLIgnoreRestTemplate(HttpComponentsClientHttpRequestFactory requestFactory) {
        super(requestFactory);
        initialize();
    }

    private void initialize() {
        try {
            // 创建信任所有证书的 SSLContext
            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, new TrustManager[]{new X509TrustManager() {
                @Override
                public void checkClientTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                }

                @Override
                public void checkServerTrusted(X509Certificate[] x509Certificates, String s) throws CertificateException {
                }

                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }
            }}, null);

            // 创建忽略 SSL 证书验证的 HttpClient
            HttpComponentsClientHttpRequestFactory requestFactory = new HttpComponentsClientHttpRequestFactory();
            requestFactory.setHttpClient(HttpClients.custom().setSSLContext(sslContext)
                    .setSSLHostnameVerifier((hostname, session) -> true).build());

            setRequestFactory(requestFactory);
        } catch (Exception e) {
            throw new RuntimeException("Failed to initialize SSLIgnoreRestTemplate", e);
        }
    }

    // 如果有其他需要扩展的方法，可以在这里进行覆盖

    @Override
    public <T> T execute(String url, HttpMethod method, RequestCallback requestCallback,
                         ResponseExtractor<T> responseExtractor, Object... uriVariables) {
        return super.execute(url, method, requestCallback, responseExtractor, uriVariables);
    }
    
    // ...
}

使用时，你可以像使用普通的 RestTemplate 一样进行请求。这个自定义的 RestTemplate 将会忽略 SSL 证书验证。例如：

RestTemplate restTemplate = new SSLIgnoreRestTemplate();
ResponseEntity<String> response = restTemplate.exchange("https://your-url.com", HttpMethod.GET, null, String.class);

需要注意的是，忽略 SSL 证书验证存在安全风险，因此建议仅在开发和测试环境中使用，并不推荐在生产环境中使用。
