springboot 使用RestTemplate调用https接口绕过证书限制

springboot 使用RestTemplate调用https接口unable to find valid certification path to requested targer pfix，可以绕过证书

使用以下 代码即可绕过证书限制

`@Slf4j
public class RestTemplateUtil {

public static RestTemplate getRestTemplate(int timeOut){
    ClientHttpRequestFactory requestFactory = null;
    try {
        requestFactory = new HttpComponentsClientHttpRequestFactory(httpClient(timeOut));
    } catch (Exception e) {
        log.info("RestTemplateConfig 出现异常：",e);
    }
    return new RestTemplate(requestFactory);
}

/**
 * 绕过ssl 验证
 */
private static org.apache.http.client.HttpClient httpClient(int timeOut) throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
    RequestConfig requestConfig = RequestConfig.custom()
            .setSocketTimeout(timeOut) // 服务器返回数据(response)的时间，超时抛出read timeout
            .setConnectTimeout(timeOut) // 连接上服务器(握手成功)的时间，超时抛出connect timeout
            .setConnectionRequestTimeout(timeOut)// 从连接池中获取连接的超时时间，超时抛出ConnectionPoolTimeoutException
            .build();
    SSLContext sslContext = SSLContextBuilder.create().setProtocol(SSLConnectionSocketFactory.SSL).loadTrustMaterial((x, y) -> true).build();
    return HttpClientBuilder.create().setDefaultRequestConfig(requestConfig).setSSLContext(sslContext).setSSLHostnameVerifier((x, y) -> true).build();
}
