## Оптимизация сети
|
||
|
||
### 1. Connection Pooling
|
||
```java
|
||
// Оптимизация HTTP соединений
|
||
@Configuration
|
||
public class HttpClientConfig {
|
||
@Bean
|
||
public RestTemplate restTemplate() {
|
||
HttpComponentsClientHttpRequestFactory factory =
|
||
new HttpComponentsClientHttpRequestFactory();
|
||
|
||
// Настройка пула соединений
|
||
PoolingHttpClientConnectionManager connectionManager =
|
||
new PoolingHttpClientConnectionManager();
|
||
connectionManager.setMaxTotal(100);
|
||
connectionManager.setDefaultMaxPerRoute(20);
|
||
|
||
CloseableHttpClient httpClient = HttpClients.custom()
|
||
.setConnectionManager(connectionManager)
|
||
.setDefaultRequestConfig(RequestConfig.custom()
|
||
.setConnectTimeout(5000)
|
||
.setSocketTimeout(10000)
|
||
.build())
|
||
.build();
|
||
|
||
factory.setHttpClient(httpClient);
|
||
return new RestTemplate(factory);
|
||
}
|
||
}
|
||
```
|
||
|
||
### 2. Compression
|
||
```java
|
||
// Сжатие HTTP ответов
|
||
@Configuration
|
||
public class CompressionConfig {
|
||
@Bean
|
||
public FilterRegistrationBean<CompressionFilter> compressionFilter() {
|
||
FilterRegistrationBean<CompressionFilter> registration =
|
||
new FilterRegistrationBean<>();
|
||
registration.setFilter(new CompressionFilter());
|
||
registration.addUrlPatterns("/*");
|
||
registration.setName("compressionFilter");
|
||
registration.setOrder(1);
|
||
return registration;
|
||
}
|
||
}
|
||
|
||
@Component
|
||
public class CompressionFilter implements Filter {
|
||
@Override
|
||
public void doFilter(ServletRequest request, ServletResponse response,
|
||
FilterChain chain) throws IOException, ServletException {
|
||
|
||
HttpServletRequest httpRequest = (HttpServletRequest) request;
|
||
HttpServletResponse httpResponse = (HttpServletResponse) response;
|
||
|
||
String acceptEncoding = httpRequest.getHeader("Accept-Encoding");
|
||
if (acceptEncoding != null && acceptEncoding.contains("gzip")) {
|
||
httpResponse.setHeader("Content-Encoding", "gzip");
|
||
GzipResponseWrapper gzipResponse = new GzipResponseWrapper(httpResponse);
|
||
chain.doFilter(request, gzipResponse);
|
||
gzipResponse.finish();
|
||
} else {
|
||
chain.doFilter(request, response);
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
### 3. CDN Integration
|
||
```java
|
||
// Интеграция с CDN
|
||
@Service
|
||
public class CDNService {
|
||
@Value("${cdn.base-url}")
|
||
private String cdnBaseUrl;
|
||
|
||
public String getCDNUrl(String path) {
|
||
return cdnBaseUrl + "/" + path;
|
||
}
|
||
|
||
public void uploadToCDN(String path, byte[] content) {
|
||
// Загрузка контента в CDN
|
||
// Реализация зависит от выбранного CDN провайдера
|
||
}
|
||
|
||
public void invalidateCDNCache(String path) {
|
||
// Инвалидация кэша CDN
|
||
// Реализация зависит от выбранного CDN провайдера
|
||
}
|
||
}
|
||
```
