spring代理实现
使用Spring RestTemplate发送请求时,可以通过以下方式设置代理:
1. 在RestTemplate的HttpClient中设置代理:
```java
HttpClient httpClient = HttpClientBuilder.create()
.setProxy(new HttpHost("proxy.host.com", 8080))
.build();
HttpComponentsClientHttpRequestFactory factory = new HttpComponentsClientHttpRequestFactory(httpClient);
RestTemplate restTemplate = new RestTemplate(factory);
```
2. 在RestTemplate的SimpleClientHttpRequestFactory中设置代理:
```java
SimpleClientHttpRequestFactory factory = new SimpleClientHttpRequestFactory();
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("proxy.host.com", 8080));
factory.setProxy(proxy);
RestTemplate restTemplate = new RestTemplate(factory);
```
3. 在RestTemplate的ClientHttpRequestInterceptor中设置代理:
```java
RestTemplate restTemplate = new RestTemplate();
restTemplate.setInterceptors(Collections.singletonList((request, body, execution) -> {
request.getHeaders().add("Proxy-Authorization", "Basic " + Base64.getEncoder().encodeToString("username:password".getBytes()));
return execution.execute(request, body);
}));
```
以上三种方式都可以设置代理,根据实际情况选择即可。
