spring - 使用 HttpComponentsMessageSender 的具有基本身份验证的 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 编写了一个 Web 服务客户端。类。

当我将模板的 MessageSender 创建为 org.springframework.ws.transport.http.CommonsHttpMessageSender 时，我的 Web 服务客户端调用 Web 服务工作正常。对象 bean 与 org.apache.commons.httpclient.UsernamePasswordCredentials并且，尽管客户端可以工作，但代码中突出显示了一条警告，指出 CommonsHttpMessageSender类现在已弃用，我应该使用 HttpComponentsMessageSender相反。

我尝试重新配置客户端的 WebServiceTemplate使用较新的 HttpComponentsMessageSender 工作类，但我无法正确配置基本身份验证部分。换新HttpComponentsMessageSender类，我已经使用 org.apache.http.auth.UsernamePasswordCredentials 创建了凭据类，但是，当我调用 Web 服务时，凭据似乎无法用于请求？是否有 WebServiceTemplate 客户端的工作示例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使用的 jar :commons-httpclient-3.1 , spring-ws-core-2.2.0.RELEASE .

我的新类的非工作代码使用的 jar :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:

使用 HttpComponentsMessageSender与 UsernamePasswordCredentials .请注意 HttpComponentsMessageSender必须创建为 Spring bean 或者您必须调用 afterPropertiesSet手动正确设置 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;
    }

}
