[网络协议]RestTemplate与OkHttpClient的使用

RestTemplate restTemplate = new RestTemplate(
                new OkHttp3ClientHttpRequestFactory(
                        new OkHttpClient().newBuilder()
                                .connectTimeout(30, TimeUnit.SECONDS)
                                .readTimeout(30, TimeUnit.SECONDS)
                                .writeTimeout(30, TimeUnit.SECONDS)
                                .hostnameVerifier((s, sslSession) -> true)
                                .followRedirects(false) // 禁止重定向
                                .build())
        );
System.out.println(restTemplate.getForObject("https://www.baidu.com",String.class));
System.out.println(restTemplate.getForObject("http://www.baidu.com",String.class));
