### 1.HttpURLConnection ###

#### 1.1配置Connection ####

if(url.startsWith(PROTECT_HTTPS)){
    	HttpsURLConnection https = (HttpsURLConnection) connection;
    	trustAllHosts(https);
    	https.setHostnameVerifier(DO_NOT_VERIFY);
    }

#### 1.2 trustAllCerts ####

/** * 信任管理器 */
    private static final TrustManager[] trustAllCerts = new TrustManager[]{ 
        new X509TrustManager() { 
            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() { 
                return new java.security.cert.X509Certificate[]{ };
            }
    
            @Override
            public void checkClientTrusted(X509Certificate[] chain, String authType) { 
            }
    
            @Override
            public void checkServerTrusted(X509Certificate[] chain, String authType) { 
            }
        }
    };

#### 1.3 trushAllHost ####

/** * 信任所有host * @param connection 链接 * @return 返回证书工厂 */
    private static SSLSocketFactory trustAllHosts(HttpsURLConnection connection) { 
        SSLSocketFactory oldFactory = connection.getSSLSocketFactory();
        try { 
            SSLContext sc = SSLContext.getInstance("TLS");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
            SSLSocketFactory newFactory = sc.getSocketFactory();
            connection.setSSLSocketFactory(newFactory);
        } catch (Exception e) { 
            e.printStackTrace();
        }
        return oldFactory;
    }

#### 1.4 设置不校验主机 ####

/** * 设置不验证主机 */
    private static final HostnameVerifier DO_NOT_VERIFY = (hostname, session) -> true;

### 2.HttpClient ###

#### 2.1 创建SSLContext ####

SSLContext sslContext = = new SSLContextBuilder().loadTrustMaterial(null, (certificate, authType) -> true).build();

#### 2.2 创建httpClient ####

HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
    httpClient = getHttpClientBuilder().setSSLContext(sslContext)
        .setSSLHostnameVerifier(new NoopHostnameVerifier())
        .build();

### 3.RestTemplate ###

#### 3.1 新建配置 ####

import java.security.KeyManagementException;
    import java.security.KeyStoreException;
    import java.security.NoSuchAlgorithmException;
     
    import javax.net.ssl.SSLContext;
     
    import org.apache.http.conn.ssl.NoopHostnameVerifier;
    import org.apache.http.conn.ssl.SSLConnectionSocketFactory;
    import org.apache.http.impl.client.CloseableHttpClient;
    import org.apache.http.impl.client.HttpClientBuilder;
    import org.apache.http.impl.client.HttpClients;
    import org.apache.http.ssl.SSLContexts;
    import org.apache.http.ssl.TrustStrategy;
    import org.springframework.context.annotation.Bean;
    import org.springframework.context.annotation.Configuration;
    import org.springframework.http.client.ClientHttpRequestFactory;
    import org.springframework.http.client.HttpComponentsClientHttpRequestFactory;
    import org.springframework.web.client.RestTemplate;
     
    @Configuration
    public class RestTemplateConfig { 
     
    	@Bean
    	public RestTemplate restTemplate(ClientHttpRequestFactory factory) { 
    		return new RestTemplate(factory);
    	}
     
    	@Bean
    	public ClientHttpRequestFactory simpleClientHttpRequestFactory() { 
    		HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
    		factory.setConnectTimeout(3000);
    		factory.setReadTimeout(5000);
    		return factory;
    	}
     
    	public static HttpComponentsClientHttpRequestFactory generateHttpRequestFactory()
    			throws NoSuchAlgorithmException, KeyManagementException, KeyStoreException { 
    		TrustStrategy acceptingTrustStrategy = (x509Certificates, authType) -> true;
    		SSLContext sslContext = SSLContexts.custom().loadTrustMaterial(null, acceptingTrustStrategy).build();
    		SSLConnectionSocketFactory connectionSocketFactory = new SSLConnectionSocketFactory(sslContext,
    				new NoopHostnameVerifier());
    		HttpClientBuilder httpClientBuilder = HttpClients.custom();
    		httpClientBuilder.setSSLSocketFactory(connectionSocketFactory);
    		CloseableHttpClient httpClient = httpClientBuilder.build();
    		HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
    		factory.setHttpClient(httpClient);
    		return factory;
    	}
     
    }

#### 3.2 使用restTemplate ####

log.info("--------------开始请求");
    HttpHeaders headers = new HttpHeaders();
    // headers.set("token", tokenStr);
    headers.setContentType(MediaType.APPLICATION_JSON_UTF8);
    HttpEntity<String> entity = new HttpEntity<String>(jsonDataStr, headers);
    RestTemplate restTemplateHttps = new RestTemplate(RestTemplateConfig.generateHttpRequestFactory());
    ResponseEntity<String> stringResponseEntity = restTemplateHttps.exchange(url, HttpMethod.POST, entity, String.class);
    log.info("--------------请求结束");
    // 响应状态
    String body = stringResponseEntity.getBody();
    log.info("获取返回信息:" + body);

### 4.简单说明 ###

注：上面直接简单的绕过ssl验证，其他配置需要自行加上。除了上述方法，据说还可以通过配置jdk可以解决。
