resttemplate发送post请求忽略证书

如果你想在使用 RestTemplate 发送 POST 请求时忽略证书，可以通过创建一个自定义的 RestTemplate 来实现。下面是一个示例代码：

import org.springframework.http.client.SimpleClientHttpRequestFactory;
import org.springframework.web.client.RestTemplate;

import javax.net.ssl.*;
import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

public class CustomRestTemplate extends RestTemplate {

    public CustomRestTemplate() {
        super();
        setRequestFactory(new SimpleClientHttpRequestFactory() {
            @Override
            protected void prepareConnection(HttpURLConnection connection, String httpMethod) throws IOException {
                if (connection instanceof HttpsURLConnection) {
                    ((HttpsURLConnection) connection).setHostnameVerifier(new HostnameVerifier() {
                        @Override
                        public boolean verify(String hostname, SSLSession session) {
                            return true;
                        }
                    });
                    ((HttpsURLConnection) connection).setSSLSocketFactory(createSslSocketFactory());
                }
                super.prepareConnection(connection, httpMethod);
            }
        });
    }

    private static SSLSocketFactory createSslSocketFactory() {
        SSLSocketFactory sslSocketFactory = null;
        try {
            TrustManager[] trustAllCerts = 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;
                }
            }};
            SSLContext sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
            sslSocketFactory = sslContext.getSocketFactory();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return sslSocketFactory;
    }

}

在上面的代码中，我们创建了一个自定义的 RestTemplate，其中重写了 prepareConnection 方法，在发送 HTTPS 请求时忽略了证书。

使用这个自定义的 RestTemplate，只需要在代码中实例化它并使用即可：

CustomRestTemplate restTemplate = new CustomRestTemplate();
String result = restTemplate.postForObject(url, request, String.class);
