我已经参考了这些示例，使用出站网关发送POST参数。
Spring Integration - how to send POST parameters with http outbound-gateway
然而我得到例外
网关接口
import org.springframework.http.HttpStatus;
import java.util.Map;
public interface MultipartRequestGateway {
HttpStatus postMultipartRequest(Map<String, Object> multipartRequest);
}
测试
public class TestClient {
public static void main(String[] args) {
ConfigurableApplicationContext context = new ClassPathXmlApplicationContext(
"/META-INF/spring/integration/http-outbound-config.xml");
Map<String, Object> requestMap = new HashMap<String, Object>();
requestMap.put("cardNo", "4444333322221111");
requestMap.put("currencyCode", "USD");
requestMap.put("amount", "10.00");
MultipartRequestGateway requestGateway = context.getBean("requestGateway", MultipartRequestGateway.class);
HttpStatus httpStatus = requestGateway.postMultipartRequest(requestMap);
}
}
HTTPS的自定义HTTP客户端
public class HttpClientFactory extends AbstractFactoryBean<HttpClient> {
@Override
public Class<?> getObjectType() {
return HttpClient.class;
}
@Override
protected HttpClient createInstance() throws Exception {
KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
TrustStrategy allTrust = new TrustStrategy() {
public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
return true;
}
};
SSLContext sslcontext = SSLContexts.custom().useTLS().loadTrustMaterial(trustStore, allTrust).build();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslcontext, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
return httpClient;
}
}
