restTemplate的使用（跳证书）

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);
//添加请求的参数
headers.add("key", "value");
//添加token到请求头
headers.setBearerAuth(token);
headers.setContentType(MediaType.APPLICATION_JSON);
HttpEntity<String> requestEntity = new HttpEntity<String>("{}", headers);
//  执行HTTP请求
ResponseEntity<String> response = NoHttpsClientUtils.getRestTemplate().exchange(url, HttpMethod.POST, requestEntity, String.class);  //最后的参数需要用String.class  使用其他的会报错

if (response.getStatusCodeValue() == 200){
    Object body = response.getBody();
    if(body != null){
        JSONObject json = JSONObject.parseObject((String)body);
        JSONArray jsonArray = json.getJSONArray("data");
        List<stList> lists = jsonArray.toJavaList(stList.class);
　　　　　//遍历
        for(stList list:lists){
　　　　　　　//判空
            if(!StringUtils.isEmpty(list.getCode())){
                Example example = new Example(stList.class);
                example.createCriteria().andEqualTo("Code", list.getCode());
                shipToMapper.updateByExampleSelective(list, example);
            }
        }
    }
}else {
    log.warn("请求异常");
}

需要配置的一个类

public class NoHttpsClientUtils {

    /**
     * 跳过证书效验的sslcontext
     *
     * @return
     * @throws Exception
     */
    private static SSLContext createIgnoreVerifySSL() throws Exception {
        SSLContext sc = SSLContext.getInstance("TLS");

        // 实现一个X509TrustManager接口，用于绕过验证，不用修改里面的方法
        X509TrustManager trustManager = new X509TrustManager() {
            @Override
            public void checkClientTrusted(java.security.cert.X509Certificate[] paramArrayOfX509Certificate,
                                           String paramString) throws CertificateException {
            }

            @Override
            public void checkServerTrusted(java.security.cert.X509Certificate[] paramArrayOfX509Certificate,
                                           String paramString) throws CertificateException {
            }

            @Override
            public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };
        sc.init(null, new TrustManager[] { trustManager }, null);
        return sc;
    }

    /**
     * 构造RestTemplate
     *
     * @return
     * @throws Exception
     */
    public static RestTemplate getRestTemplate() throws Exception {
        HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory();
        // 超时
        factory.setConnectionRequestTimeout(500000);
        factory.setConnectTimeout(500000);
        factory.setReadTimeout(500000);
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(createIgnoreVerifySSL(),
                // 指定TLS版本
                null,
                // 指定算法
                null,
                // 取消域名验证
                new HostnameVerifier() {
                    @Override
                    public boolean verify(String string, SSLSession ssls) {
                        return true;
                    }
                });
        CloseableHttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
        factory.setHttpClient(httpClient);
        RestTemplate restTemplate = new RestTemplate(factory);
        // 解决中文乱码问题
        restTemplate.getMessageConverters().set(1, new StringHttpMessageConverter(StandardCharsets.UTF_8));
        return restTemplate;
    }
}
