java客户端验证https连接（忽略证书验证和证书验证两种方式）

首先根据如下操作生成证书，配置springboot https，生成一个简单的https web服务

验证客户端pom依赖

</dependency>

            <dependency>

                <groupId>org.springframework.boot</groupId>

                <artifactId>spring-boot-starter-web</artifactId>

            </dependency>

            <dependency>

                <groupId>org.apache.httpcomponents</groupId>

                <artifactId>httpclient</artifactId>

                <version>4.5.10</version>

            </dependency>

            <dependency>

                <groupId>org.apache.httpcomponents</groupId>

                <artifactId>httpcore</artifactId>

                <version>4.4.12</version>

            </dependency>

httpclient和httpcore版本要对应，否则可能会出现异常

验证方式包括跳过证书验证，也即是添加信任，就像浏览器访问自签名https服务时，页面会给出提示“您的链接不是私密连接”，点击了高级，继续前往即是对该服务添加了信任，可以继续访问该网站服务，另外一种方式就是通过服务器证书来验证，下面就直接上代码

跳过证书验证方式

package com.demo.bootdemo;

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;

import org.apache.http.conn.ssl.SSLConnectionSocketFactory;

import org.apache.http.impl.client.HttpClients;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.context.annotation.Bean;

import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;

import org.springframework.stereotype.Component;

import org.springframework.web.client.RestTemplate;

@Component

public class SkipVerifyRestTemplateBuilder {

	private Logger logger = LoggerFactory.getLogger(SkipVerifyRestTemplateBuilder.class);

	// 初始化ssl resttemplate

	@Bean("skipVerifyRestTemplate")

	public RestTemplate skipVerifyRestTemplate() {

		RestTemplate rest = new RestTemplate();

		SSLConnectionSocketFactory buildSSLSocketFactory = null;

		try {

			buildSSLSocketFactory = this.buildSSLSocketFactory();

		} catch (Exception e) {

			logger.error("", e);

		}

		HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(

				HttpClients.custom().setSSLSocketFactory(buildSSLSocketFactory).build());

		factory.setConnectionRequestTimeout(1000);

		factory.setConnectTimeout(1000);

		rest.setRequestFactory(factory);

		return rest;

	}

	private SSLConnectionSocketFactory buildSSLSocketFactory() throws Exception {

		SSLContext sslContext = SSLContext.getInstance("SSL");

		// 设置信任证书（绕过TrustStore验证）

		sslContext.init(null, new TrustManager[] { new AuthX509TrustManager() }, null);

		HttpsURLConnection.setDefaultSSLSocketFactory(sslContext.getSocketFactory());

		SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslContext,

				new String[] { "TLSv1" }, null, new HostnameVerifier() {

					// hostname,默认返回true,不验证hostname

					@Override

					public boolean verify(String urlHostName, SSLSession session) {

						return true;

					}

				});

		return sslConnectionSocketFactory;

	}

	private class AuthX509TrustManager implements TrustManager, X509TrustManager {

		public X509Certificate[] getAcceptedIssuers() {

			return null;

		}

		public void checkServerTrusted(X509Certificate[] certs, String authType)

				throws java.security.cert.CertificateException {

			return;

		}

		public void checkClientTrusted(X509Certificate[] certs, String authType) throws CertificateException {

			return;

		}

	}

}

第二种跳过证书验证方式

import org.springframework.context.annotation.Bean;

import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;

import org.springframework.stereotype.Component;

import org.springframework.web.client.RestTemplate;

@Component

public class SecondSkipVerifyRestTemplateBuilder {

    @Bean("secondSkipRestTemplate")

    public RestTemplate verifyCaRestTemplate() {

        RestTemplate rest = new RestTemplate();

        SSLConnectionSocketFactory ssLSocketFactory = null;

        try {

            ssLSocketFactory = sslFactory("PKCS12", "abc123");

        } catch (Exception e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory(

                HttpClients.custom().setSSLSocketFactory(ssLSocketFactory).build());

        // 设置传递数据超时时长

        httpRequestFactory.setReadTimeout(1000);

        rest.setRequestFactory(httpRequestFactory);

        // 如果返回的数据非json则可能需要添加对应httpmessageconverter

        // Jaxb2RootElementHttpMessageConverter converter = new

        // Jaxb2RootElementHttpMessageConverter();

        //

        // List<MediaType> mediaTypeList = new ArrayList<>();

        //

        // List<HttpMessageConverter<?>> list = new ArrayList<>();

        // list.add(converter);

        // rest.setMessageConverters(list);

        return rest;

    }

    public SSLConnectionSocketFactory sslFactory(String keyStoreType, String keyPassword) {

        SSLConnectionSocketFactory sslConnectionSocketFactory = null;

        try {

            SSLContext sslcontext = SSLContexts.custom()

                    // //忽略掉对服务器端证书的校验

                    .loadTrustMaterial(new TrustStrategy() {

                        @Override

                        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {

                            return true;

                        }

                    }).build();

            sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslcontext, new String[] { "TLSv1" }, null,

                    SSLConnectionSocketFactory.getDefaultHostnameVerifier());

        } catch (Exception e) {

            e.printStackTrace();

        }

        return sslConnectionSocketFactory;

    }

}

根据证书验证

package com.demo.bootdemo;

import java.io.IOException;

import java.security.KeyStore;

import java.util.ArrayList;

import java.util.List;

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.context.annotation.Bean;

import org.springframework.core.io.Resource;

import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;

import org.springframework.stereotype.Component;

import org.springframework.web.client.RestTemplate;

@Component

public class VerifyCaRestTemplateBuilder {

    private Logger logger = LoggerFactory.getLogger(VerifyCaRestTemplateBuilder.class);

    @Value("classpath:cert.p12")

    private Resource certFile;

    @Bean("verifyCaRestTemplate")

    public RestTemplate verifyCaRestTemplate() {

        RestTemplate rest = new RestTemplate();

        SSLConnectionSocketFactory ssLSocketFactory = null;

        try {

            ssLSocketFactory = sslFactory("PKCS12", "abc123");

        } catch (Exception e) {

            logger.error("", e);

        }

        HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory(

                HttpClients.custom().setSSLSocketFactory(ssLSocketFactory).build());

        // 设置传递数据超时时长

        httpRequestFactory.setReadTimeout(1000);

        rest.setRequestFactory(httpRequestFactory);

        // 如果返回的数据非json则可能需要添加对应httpmessageconverter

        // Jaxb2RootElementHttpMessageConverter converter = new

        // Jaxb2RootElementHttpMessageConverter();

        //

        // List<MediaType> mediaTypeList = new ArrayList<>();

        // mediaTypeList.addAll(converter.getSupportedMediaTypes());

        // mediaTypeList.add(MediaType.TEXT_HTML);

        return rest;

    }

    public SSLConnectionSocketFactory sslFactory(String keyStoreType, String keyPassword) {

        SSLConnectionSocketFactory sslConnectionSocketFactory = null;

        try {

            KeyStore keyStore = null;

            try {

                keyStore = KeyStore.getInstance(keyStoreType);

                keyStore.load(certFile.getInputStream(), keyPassword.toCharArray());

            } catch (IOException e) {

                logger.error("", e);

            }

            HostnameVerifier hv = new HostnameVerifier() {

                @Override

                public boolean verify(String urlHostName, SSLSession session) {

                    // 如果需要验证https域名，可以在该处做判断,如果访问的hostname与判断不一致，则会出现如下异常

                    // if("localhost".equals(urlHostName)) {

                    // return true;

                    // }else {

                    // return false;

                    // }

                    // 此处不校验hostname，接收所有hostname，只是用于测试。

                    return true;

                }

            };

            SSLContext sslcontext = SSLContexts.custom()

                    .loadTrustMaterial(certFile.getFile(), keyPassword.toCharArray(), new TrustSelfSignedStrategy())

                    .loadKeyMaterial(keyStore, keyPassword.toCharArray()).build();

            sslConnectionSocketFactory = new SSLConnectionSocketFactory(sslcontext, new String[] { "TLSv1" }, null, hv);

        } catch (Exception e) {

            e.printStackTrace();

        }

        return sslConnectionSocketFactory;

    }

}

注：在上述HostnameVerifier 中，可以验证hostname有效性，如果无效，返回fase，则会出现类似以下异常

javax.net.ssl.SSLPeerUnverifiedException: Certificate for <localhost> doesn't match any of the subject alternative names: []

测试controller

package com.demo.bootdemo;

import javax.annotation.Resource;

import org.springframework.http.ResponseEntity;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import org.springframework.web.client.RestTemplate;

@Controller

public class HttpsSendController {

    @Resource(name = "skipVerifyRestTemplate")

    private RestTemplate skipVerifyRestTemplate;

    @Resource(name = "verifyCaRestTemplate")

    private RestTemplate verifyCaRestTemplate;

    @Resource(name = "secondSkipRestTemplate")

    private RestTemplate secondSkipRestTemplate;

    @RequestMapping("/skip")

    @ResponseBody

    public String skipVerifyCert() {

        ResponseEntity<String> forEntity = skipVerifyRestTemplate.getForEntity("https://127.0.0.1:8443/test",

                String.class, new Object[] {});

        return forEntity.getBody();

    }

    @RequestMapping("/secondskip")

    @ResponseBody

    public String secondSkipVerifyCert() {

        ResponseEntity<String> forEntity = skipVerifyRestTemplate.getForEntity("https://127.0.0.1:8443/test",

                String.class, new Object[] {});

        return forEntity.getBody();

    }

    @RequestMapping("/verify")

    @ResponseBody

    public String verifyCert() {

        ResponseEntity<String> forEntity = verifyCaRestTemplate.getForEntity("https://127.0.0.1:8443/test",

                String.class, new Object[] {});

        return forEntity.getBody();

    }

}

可分别访问当前客户端的skip、secondskip、verify验证结果
