本文介绍了一种在Java中调用第三方HTTPS接口时忽略安全证书的方法，通过自定义信任管理器和主机名验证器实现对所有证书的信任，适用于测试或特殊情况下的需求。

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.TrustManager;
import javax.net.ssl.X509TrustManager;
/**

public class SslUtil {

	private static void trustAllHttpsCertificates() throws Exception {  
	    TrustManager[] trustAllCerts = new TrustManager[1];  
	    TrustManager tm = new miTM();  
	    trustAllCerts[0] = tm;  
	    SSLContext sc = SSLContext.getInstance("SSL");  
	    sc.init(null, trustAllCerts, null);  
	    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());  
	}  
	  
	static class miTM implements TrustManager,X509TrustManager {  
	    public X509Certificate[] getAcceptedIssuers() {  
	        return null;  
	    }  
	  
	    public boolean isServerTrusted(X509Certificate[] certs) {  
	        return true;  
	    }  
	  
	    public boolean isClientTrusted(X509Certificate[] certs) {  
	        return true;  
	    }  
	  
	    public void checkServerTrusted(X509Certificate[] certs, String authType)  
	            throws CertificateException {  
	        return;  
	    }  
	  
	    public void checkClientTrusted(X509Certificate[] certs, String authType)  
	            throws CertificateException {  
	        return;  
	    }  
	}  
	   
	/** 
	 * 忽略HTTPS请求的SSL证书，必须在openConnection之前调用 
	 * @throws Exception 
	 */  
	public static void ignoreSsl() throws Exception{  
	    HostnameVerifier hv = new HostnameVerifier() {  
	        public boolean verify(String urlHostName, SSLSession session) {  
	            System.out.println("Warning: URL Host: " + urlHostName + " vs. " + session.getPeerHost());  
	            return true;  
	        }  
	    };  
	    trustAllHttpsCertificates();  
	    HttpsURLConnection.setDefaultHostnameVerifier(hv);  
	}  


}

在调用接口前调用ignoreSsl()方法即可：如：

RestTemplate restTemplate = new RestTemplate();
		HttpHeaders headers=null;
		JSONObject jsonObj = null;
		HttpEntity<String> formEntity = new HttpEntity<String>(jsonObj.toString(), headers);
		SslUtil.ignoreSsl();//忽略安全证书
       //调用第三方接口
		ResponseEntity<String> exchange = restTemplate.exchange(url, HttpMethod.POST, formEntity, String.class);
