SpringBoot 设置HTTP代理访问
遇到这样的一个场景，代码部署到私有服务器上去之后，这台私有服务器a无法直接访问公网，需要通过代理转发到另外一台专门访问公网的服务器b, 让服务器b去请求对应的公网ip，于是就需要设置Http代理。
通常使用springboot会用到两种不同的httpclient
-
spring-boot-starter-webflux 这个包下面的WebClient
-
Spring-web 这个包下面的RestTemplate
WebClient
通过设置Httpclinet添加绑定的代理地址，然后给WebClient里添加这个Httpclient
HttpClient httpClient = HttpClient.create().proxy(proxy -> proxy.type(ProxyProvider.Proxy.HTTP).address(new InetSocketAddress("192.168.0.1", 8080)) // 你的代理IP和端口);
WebClient webClient = webClientBuilder.baseUrl("https://www.baidu.com").clientConnector(new ReactorClientHttpConnector(httpClient)).build();
String result = webClient.get().retrieve().bodyToMono(String.class).block();RestTemplate
// 服务器代理
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("192.168.0.1", 8080));
// 配置 request factory
SimpleClientHttpRequestFactory requestFactory = new SimpleClientHttpRequestFactory();
requestFactory.setProxy(proxy);
RestTemplate restTemplate = new RestTemplate();
ProxySetting proxySetting = SpringContextHolder.getBean(ProxySetting.class);
// This allows us to read the response more than once - Necessary for debugging.
// 如果开启代理，则配置走服务器代理。否则走本地调试
if (proxySetting.isEnable()) {restTemplate.setRequestFactory(requestFactory);
} else {restTemplate.setRequestFactory(new SimpleClientHttpRequestFactory());
}
DefaultUriBuilderFactory uriBuilderFactory = new DefaultUriBuilderFactory(); uriBuilderFactory.setEncodingMode(DefaultUriBuilderFactory.EncodingMode.VALUES_ONLY);
restTemplate.setUriTemplateHandler(uriBuilderFactory);
String url = "https://www.baidu.com"
String response = restTemplate.getForObject(url, String.class);
