如何使用Spring RestTemplate调用HTTPS restful Web服务

Question

我正在使用Tomcat7,Spring框架进行ReST Web服务.我试图使用Spring RestTemplate调用https Web服务.我收到以下错误:

无法找到要求目标的有效证书路径; 嵌套异常是javax.net.ssl.SSLHandshakeException:sun.security.validator.ValidatorException:PKIX路径构建失败:sun.security.provider.certpath.SunCertPathBuilderException:无法找到所请求目标的有效证书路径

我在stackoverflow上在线检查.我尝试了url中的示例代码: 使用Spring RestTemplate访问Https Rest服务

我无法让它发挥作用.任何人都可以根据下面的代码告诉我,我需要更改什么？也有人可以告诉我或者向我提供我需要的java库的pom.xml文件吗？

        import org.springframework.web.bind.annotation.RequestMethod;
        import org.springframework.web.client.RestTemplate;

        import com.fasterxml.jackson.core.JsonGenerationException;
        import com.fasterxml.jackson.databind.JsonMappingException;
        import com.fasterxml.jackson.databind.ObjectMapper;
        import com.journaldev.spring.controller.EmpRestURIConstants;
        import com.journaldev.spring.model.CostControlPost;
        import com.journaldev.spring.model.Employee;
        import com.journaldev.spring.model.RfxForUpdate;

        import static org.junit.Assert.*;
        import org.apache.commons.codec.binary.Base64;


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


        public class TestExample2
        {
            public static final String SERVER_LIST="https://abc/sourcing/testServices";


            @Test
            public void testGetListOfServiceNames()
            {
                try
                {


                    RestTemplate restTemplate = new RestTemplate();
                    ResponseEntity<String> response = restTemplate.exchange(SERVER_LIST,HttpMethod.GET,null,String.class);
                    assertNotNull(response);    
                }
                catch(Exception e)
                {
                    System.out.println("e:"+e.getMessage());
                }
            }


        }

您需要在密钥库中拥有证书,或者您可以接受所有证书(关闭忽略证书验证)

所以你可以将rest模板的bean重新定义为

import javax.net.ssl.SSLContext;
import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
import org.apache.http.conn.ssl.TrustStrategy;
import java.security.cert.X509Certificate;

@Bean
public RestTemplate restTemplate() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {
    TrustStrategy acceptingTrustStrategy = (X509Certificate[] chain, String authType) -> true;

    SSLContext sslContext = org.apache.http.ssl.SSLContexts.custom()
                    .loadTrustMaterial(null, acceptingTrustStrategy)
                    .build();

    SSLConnectionSocketFactory csf = new SSLConnectionSocketFactory(sslContext);

    CloseableHttpClient httpClient = HttpClients.custom()
                    .setSSLSocketFactory(csf)
                    .build();

    HttpComponentsClientHttpRequestFactory requestFactory =
                    new HttpComponentsClientHttpRequestFactory();

    requestFactory.setHttpClient(httpClient);
    RestTemplate restTemplate = new RestTemplate(requestFactory);
    return restTemplate;
 }

除了apache核心,客户端和依赖项之外,您不需要额外的jar.
