该配置类主要设置了RestTemplate的HTTP客户端实现，使用HttpComponentsClientHttpRequestFactory，并详细配置了HttpClient的连接池管理，包括最大连接数、每个路由的最大连接数以及各种超时时间。

@Configuration
@RefreshScope
public class RestTemplateConfig {

    @Value("${http.max.total}")
    private Integer httpMaxTotal;

    @Value("${http.max.per.route : 100}")
    private Integer httpDefaultMaxPerRoute;

    @Value("${http.socket.time.out : 30000}")
    private Integer httpSocketTimeout;

    @Value("${http.connect.time.out : 10000}")
    private Integer httpConnectTimeout;

    @Value("${http.connect.req.time.out : 1000}")
    private Integer httpConnectionRequestTimeout;

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate(httpRequestFactory());
    }

    @Bean
    public ClientHttpRequestFactory httpRequestFactory() {
        return new HttpComponentsClientHttpRequestFactory(httpClient());
    }

    @Bean
    public HttpClient httpClient() {
        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("http", PlainConnectionSocketFactory.getSocketFactory())
                .register("https", SSLConnectionSocketFactory.getSocketFactory())
                .build();
        PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(registry);
        //设置整个连接池最大连接数  400
        connectionManager.setMaxTotal(httpMaxTotal);

        //路由是对maxTotal的细分
        connectionManager.setDefaultMaxPerRoute(httpDefaultMaxPerRoute);
        RequestConfig requestConfig = RequestConfig.custom()
                .setSocketTimeout(httpSocketTimeout)  //返回数据的超时时间
                .setConnectTimeout(httpConnectTimeout) //连接上服务器的超时时间
                .setConnectionRequestTimeout(httpConnectionRequestTimeout) //从连接池中获取连接的超时时间
                .build();
        return HttpClientBuilder.create()
                .setDefaultRequestConfig(requestConfig)
                .setConnectionManager(connectionManager)
                .build();
    }
