如何使用HttpsUrlConnectionMessageSender进行连接池

Question

我正在尝试使用Spring WS发出Soap请求。请求需要跨客户端证书发送到服务器。我已经找到了向服务器发出正确请求的配置。代码如下所示

@Bean
    public HttpsUrlConnectionMessageSender messageSender() throws Exception {
        HttpsUrlConnectionMessageSender httpsUrlConnectionMessageSender = new HttpsUrlConnectionMessageSender();
        httpsUrlConnectionMessageSender.setTrustManagers(<TrustManager>);
        httpsUrlConnectionMessageSender.setKeyManagers(<KeyManager>);
        httpsUrlConnectionMessageSender.setHostnameVerifier(new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });
        return httpsUrlConnectionMessageSender;
    }

    @Bean
    @Scope
    public WebServiceTemplate webServiceTemplate() throws Exception {
        WebServiceTemplate webServiceTemplate = new WebServiceTemplate(<messageFactory>);
        webServiceTemplate.setMarshaller(<jaxb2Marshaller>);
        webServiceTemplate.setUnmarshaller(<jaxb2Marshaller>);
        webServiceTemplate.setDefaultUri(<URL>);
        webServiceTemplate.setMessageSender(());
        return webServiceTemplate;
    }

现在我想知道HttpsUrlConnectionMessageSender如何管理连接？它是为每个请求创建新连接还是具有内部连接池。我们如何在这里使用外部连接池？

Answer 1

客户端的默认连接池为20，每个请求的默认连接池为2。

但是您可以这样覆盖它：

public HttpComponentsMessageSender httpComponentsMessageSender(Integer readTimeout, Integer connectionTimeOut,
            Integer throttlingLimit) {
    HttpComponentsMessageSender sender = new HttpComponentsMessageSender();
    sender.setReadTimeout(readTimeout);
    sender.setConnectionTimeout(connectionTimeOut);
    PoolingHttpClientConnectionManager connManager = new PoolingHttpClientConnectionManager();
    CloseableHttpClient poolingHttpSoapClient = HttpClients.custom().setConnectionManager(connManager)
            .addInterceptorFirst(new RemoveSoapHeadersInterceptor()).setMaxConnPerRoute(throttlingLimit)
            .setMaxConnTotal(throttlingLimit + 1).build();
    sender.setHttpClient(poolingHttpSoapClient);
    return sender;
}
