使用HttpComponentsMessageSender的基于Auth的WebServiceTemplate

Question

我正在尝试测试当前使用基本身份验证保护的Spring Web服务.对于这些测试,我使用Spring的WebServiceTemplate类编写了一个Web服务客户端.

我的Web服务客户端调用Web Service的工作没关系,当我创建模板的messageSender,和作为org.springframework.ws.transport.http.CommonsHttpMessageSender对象豆与org.apache.commons.httpclient.UsernamePasswordCredentials和,虽然客户端运行,代码有一个警告高亮说,CommonsHttpMessageSender类是现在已经过时,我应该使用HttpComponentsMessageSender来代替.

我已经尝试重新配置客户端WebServiceTemplate以使用较新的HttpComponentsMessageSender类工作,但我无法正确配置它的基本身份验证部分.对于新HttpComponentsMessageSender类,我使用org.apache.http.auth.UsernamePasswordCredentials该类创建了凭据,但是当我调用Web Service时,凭据似乎无法与请求一起使用？是否有一个WebServiceTemplate客户端的工作示例,它使用这些较新的类来验证请求等？

我的工作代码与旧的弃用类的Jars使用:commons-httpclient-3.1, spring-ws-core-2.2.0.RELEASE.

我不工作的代码与新类罐用途:httpclient-4.3.4,httpcore-4.3.2,spring-ws-core-2.2.0.RELEASE.

这是我们项目的锻炼org.apache.httpcomponents： httpclient-4.5.3,httpcore-4.4.6

我们创建拦截器标头RequestDefaultHeaders reqHeader = new RequestDefaultHeaders(headers)，然后.addInterceptorLast(reqHeader)在构建时使用添加到 httpClientCloseableHttpClient

配置类：

import org.apache.http.message.BasicHeader;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.Header;
import org.apache.http.client.protocol.RequestDefaultHeaders;


@Bean
HttpClient createHttpClient() {
    List<Header> headers = new ArrayList<>();
    BasicHeader authHeader = new BasicHeader("Authorization", "Basic " + base64authUserPassword());
    headers.add(authHeader);
    // add more header as more as needed

    RequestDefaultHeaders reqHeader = new RequestDefaultHeaders(headers);

    CloseableHttpClient httpClient = 
        HttpClients.custom()
            .addInterceptorFirst(new HttpComponentsMessageSender.RemoveSoapHeadersInterceptor())
            .addInterceptorLast(reqHeader)
            .build();
    return httpClient;
}

@Bean
public HttpComponentsMessageSender defaultMyMessageSender() 
        throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException {

    HttpComponentsMessageSender messageSender = new HttpComponentsMessageSender(createHttpClient());
    //messageSender.setCredentials(credentials());
    return messageSender;
}

@Bean
WebServiceTemplate webServiceTemplate() throws KeyManagementException, NoSuchAlgorithmException, KeyStoreException{

    WebServiceTemplate wsTemplate = new WebServiceTemplate();
    wsTemplate.setDefaultUri(endpointURI);
    wsTemplate.setMessageSender(defaultMyMessageSender());

    return wsTemplate;
}

使用HttpComponentsMessageSender带UsernamePasswordCredentials.请注意,HttpComponentsMessageSender必须创建为Spring bean,或者必须afterPropertiesSet手动调用才能正确设置http客户端.这对我有用:

@Configuration
public class WsClientConfiguration {


    @Bean
    public ESignatureProcessorClient eSignatureProcessorClient() {
        ESignatureProcessorClient client = new ESignatureProcessorClient();
        client.setWebServiceTemplate(mwWebServiceTemplate());
        return client;
    }

    @Bean
    public WebServiceTemplate mwWebServiceTemplate() {
        Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
        marshaller.setContextPath("cz.csas.services.esignatureprocessor.v02_02");
        WebServiceTemplate template = new WebServiceTemplate(marshaller, marshaller);
        template.setDefaultUri("https://osb-st2.vs.csin.cz:5001/CSMW/WS_MW_ESignatureProcessor_v02_02");
        template.setMessageSender(defaultMwMessageSender());
        return template;
    }

    @Bean
    public HttpComponentsMessageSender defaultMwMessageSender() {
        HttpComponentsMessageSender messageSender = new HttpComponentsMessageSender();
        messageSender.setCredentials(new UsernamePasswordCredentials("user", "password"));
        return messageSender;
    }

}

最后，为了使基本身份验证与 SpringWebServiceTemplate一起spring-ws-xxx.2.2.0.RELEASE使用当前的httpclient-4.3.+类httpcore-4.3.+，我添加了一个抢占式身份验证拦截器HttpClient（如@Oliv 在使用 Apache HttpClient 4 的抢占式基本身份验证中所建议的那样）。请注意，正如 @Oliv 所指出的，此解决方案为发出的所有请求添加了身份验证。

我仍然不确定这是否是配置 Spring 的最佳方法，WebServiceTemplate但这是我发现（到目前为止）无需直接访问即可启用抢先身份验证的唯一HttpClient方法HttpClientContext对象的情况下启用抢先身份验证的唯一方法。任何更简单更好的答案我都会非常欢迎......

拦截器代码：

private static class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

    public void process(final HttpRequest request, final HttpContext context) 
            throws HttpException, IOException {

        AuthState authState = (AuthState) context.getAttribute(
                HttpClientContext.TARGET_AUTH_STATE);

        // If no auth scheme is avaialble yet, initialize it preemptively
        if ( authState.getAuthScheme() == null ) {

            CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(
                    HttpClientContext.CREDS_PROVIDER);

            HttpHost targetHost = (HttpHost) context.getAttribute(
                    HttpCoreContext.HTTP_TARGET_HOST);

            Credentials creds = credsProvider.getCredentials(
                    new AuthScope(targetHost.getHostName(), targetHost.getPort()));

            if ( creds == null ) {
                throw new HttpException("no credentials available for preemptive "
                        + "authentication");
            }

            authState.update(new BasicScheme(), creds);
        }
    }
}
