Question

使用spring-integration，我想用基本身份验证调用出站网关。我有这样的事情：

<int-http:inbound-gateway id="versionRequestGateway" 
    supported-methods="POST" request-channel="requestVersionChannel"
    reply-channel="requestTransformerVersionChannel" 
    path="/consultersite" reply-timeout="10000" request-payload-type="java.lang.String">
</int-http:inbound-gateway>
<int-http:outbound-gateway order="1" request-channel="requestVersionChannel"
    url-expression="@urlExpressionGateway.getUrlFor(payload) + '/consultersite'"
    reply-channel="responseVersionChannel"
    http-method="POST" 
    expected-response-type="java.lang.String" >
</int-http:outbound-gateway>

出站网关的URL是动态的。

我决定在出站网关上使用rest-template属性，使用：

<bean id="httpClientParams" class="org.apache.commons.httpclient.params.HttpClientParams">
    <property name="authenticationPreemptive" value="true"/>
    <property name="connectionManagerClass" value="org.apache.commons.httpclient.MultiThreadedHttpConnectionManager"/>
</bean>
<bean id="httpClient" class="org.apache.commons.httpclient.HttpClient">
    <constructor-arg ref="httpClientParams"/>
</bean>
<bean id="httpClientFactory" class="org.springframework.http.client.CommonsClientHttpRequestFactory">
    <constructor-arg ref="httpClient"/>
</bean>
<bean id="restTemplate" class="org.springframework.web.client.RestTemplate">
    <constructor-arg ref="httpClientFactory"/>
</bean>

在加载spring应用程序上下文后，在ApplicationListener中注入UsernamePasswordCredentials时，它可以正常工作。

HttpClient client = ctx.getBean("httpClient", HttpClient.class);
UsernamePasswordCredentials credentials = new UsernamePasswordCredentials("username", "password");
client.getState().setCredentials(AuthScope.ANY, credentials);

但根据出站网关的网址，用户名和密码不同。如何根据url outbound-gateway使用好用户名/密码？

有必要实现我自己的BasicSecureSimpleClientHttpRequestFactory扩展SimpleClientHttpRequestFactory来根据连接的URL映射信息Credentials。希望一个实现Spring将有一天可用... 感谢。

不要键入任何可以结合使用Spring WS HttpComponentsMessageSender和Spring WEB HttpComponentsClientHttpRequestFactory的Java代码：

<bean id="httpComponentsMessageSender" class="org.springframework.ws.transport.http.HttpComponentsMessageSender">
    <property name="credentials">
        <bean class="org.apache.commons.httpclient.UsernamePasswordCredentials">
            <constructor-arg value="userName"/>
            <constructor-arg value="password"/>
        </bean>
    </property>
</bean>

<bean id="clientHttpRequestFactory" class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">
    <property name="httpClient" value="#{httpComponentsMessageSender.httpClient}"/>
</bean>

<int-http:outbound-gateway url-expression="@urlExpressionGateway.getUrlFor(payload) + '/consultersite'"
                           request-factory="clientHttpRequestFactory"/>

我可以相信，我的答案可能不适合你的情况。但是我希望它能有所帮助。

也许需要在运行时实现自己的HttpComponentsClientHttpRequestFactory#createRequest进行身份验证并执行此操作：

method.addRequestHeader(new Header(WWW_AUTH_RESP, authstring, true));

查看HttpMethodDirector#authenticateHost

的源代码

你应该使用org.apache.http.auth.UsernamePasswordCredentials实现而不是org.apache.commons.httpclient.UsernamePasswordCredentials

<beans:bean id="httpComponentsMessageSender" class="org.springframework.ws.transport.http.HttpComponentsMessageSender">
        <beans:property name="credentials">
            <beans:bean class="org.apache.http.auth.UsernamePasswordCredentials">
                <beans:constructor-arg value="user"/>
                <beans:constructor-arg value="password"/>
            </beans:bean>
        </beans:property>
    </beans:bean>
