使用HttpComponentsMessageSender的基于Auth的WebServiceTemplate

标签： spring web-services authentication spring-security spring-ws

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。

当我使用org.springframework.ws.transport.http.CommonsHttpMessageSender创建模板的MessageSender作为org.apache.commons.httpclient.UsernamePasswordCredentials对象bean时，我的Web服务客户端调用Web服务工作正常，虽然客户端工作，但代码突出显示警告说现在已弃用CommonsHttpMessageSender类，而我应该使用HttpComponentsMessageSender。

我尝试重新配置客户端WebServiceTemplate以使用较新的HttpComponentsMessageSender类，但我无法正确配置基本身份验证部分。对于新的HttpComponentsMessageSender类，我使用org.apache.http.auth.UsernamePasswordCredentials类创建了凭据，但是当我调用Web Service时，凭据似乎无法用于请求？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？

Jars我的旧代弃用类的工作代码使用：commons-httpclient-3.1，spring-ws-core-2.2.0.RELEASE。

Jars表示我的新工作代码使用较新的类：httpclient-4.3.4，httpcore-4.3.2，spring-ws-core-2.2.0.RELEASE。

测试配置，因为它代表非工作代码：

将const Select = (props) => { var requireField; if( props.requireField ) { requireField = (<span className="text-error">*</span>); } return ( <div className="form-group"> <label className="form-label">{props.title}</label> <select name={props.name} value={props.selectedOption} onChange={props.controlFunc} className={["form-control", props.extraClass].join(' ')}> <option value="">{props.placeholder}</option> </select> </div> ); } 与HttpComponentsMessageSender一起使用。请注意，必须将UsernamePasswordCredentials创建为Spring bean，或者必须手动调用HttpComponentsMessageSender才能正确设置http客户端。 这对我有用：

这是使用org.apache.httpcomponents进行项目的锻炼： httpclient-4.5.3，httpcore-4.4.6

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

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;
}

我使用的一个解决方案是使用自定义CredentialsProvider创建自定义WebServiceMessageSender。此解决方案还设置了一个遵循默认Java代理设置的路由规划器。 

@Configuration
public class WebServiceConfiguration {

    @Bean
    public WebServiceMessageSender webServiceMessageSender(@Value("${endpoint.uri}") endpointUri, 
                                                           @Value("${endpoint.username}") String username, 
                                                           @Value("${endpoint.password}") String password) throws Exception {
        SystemDefaultRoutePlanner routePlanner = new SystemDefaultRoutePlanner(
            ProxySelector.getDefault());
        BasicCredentialsProvider credentialsProvider = new BasicCredentialsProvider();
        credentialsProvider.setCredentials(new AuthScope(endpointUri.getHost(), endpointUri.getPort(), ANY_REALM, ANY_SCHEME), new UsernamePasswordCredentials(username, password););
        CloseableHttpClient httpclient = HttpClients.custom()
            .setRoutePlanner(routePlanner)
            .addInterceptorFirst(new HttpComponentsMessageSender.RemoveSoapHeadersInterceptor())
            .setDefaultCredentialsProvider(credentialsProvider)
            .build();

        return new HttpComponentsMessageSender(httpclient);
    }
}

最后，为了使用当前WebServiceTemplate，spring-ws-xxx.2.2.0.RELEASE类使用httpclient-4.3.+中的Spring httpcore-4.3.+进行基本身份验证，我添加了一个抢占式身份验证拦截器HttpClient（由@Oliv在Preemptive Basic authentication with Apache HttpClient 4中建议）。请注意，正如@Oliv所指出的，此解决方案会对所有请求添加身份验证。

我仍然不确定这是否是配置Spring WebServiceTemplate的最佳方式，但这是我找到（目前为止）启用抢先身份验证但没有直接访问HttpClient的唯一方法是HttpClientContext对象。任何更简单更好的答案我都非常欢迎......

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);
        }
    }
}

线程虽然陈旧，但总结。

根据春季文档：

UsernamePasswordCredentials和HttpComponentsMessageSender应该是spring bean。所以定义bean并注入它们。它应该解决问题。
