如何配置 HttpClient 进行基本身份验证？

Question

我发现这个序列设置基本身份验证 这里：

HttpClient client = new HttpClient();

client.getState().setCredentials(
   new AuthScope("www.domain.com", 443, "realm"),
   new UsernamePasswordCredentials("username", "password") );

如何使用 spring 配置来实现这一点？ 背后的原因是，我需要为 spring-integration HttpOutboundGateway 启用身份验证。 我在这个主题上找到的唯一信息是这个

• 问题是：如何进行spring配置？
• 其次，如何将 HttpClient 注入到 spring-integration 中？

Answer 1

好吧，可能是这样的：（注意，没有测试任何内容 - 这只是一系列随机的想法:)）

<bean id="httpOutbound" class="org.springframework.integration.http.HttpOutboundEndpoint" >
    <property name="requestExecutor" ref="executor" />
</bean>

<bean id="executor" class="org.springframework.integration.http.CommonsHttpRequestExecutor">
    <property name="httpClient">
        <bean factory-bean="clientFactory" factory-method="getHttpClient">
    </property>
</bean>

<bean id="clientFactory" class="bla.bla.bla.HttpClientFactoryBean">
    <constructor-arg ref="httpClient" />
    <constructor-arg ref="credentials" />
</bean>

<bean id="httpClient" class="org.apache.commons.httpclient.HttpClient">
    <constructor-arg ref="httpClientParams" />
</bean>

<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="credentials" class="org.apache.commons.httpclient.UsernamePasswordCredentials">
    <constructor-arg value="user" />
    <constructor-arg value="password" />
</bean>


public class HttpClientFactoryBean{
    private HttpClient httpClient;
    public HttpClientFactoryBean(HttpClient httpClient, Credentials credentials){
        this.httpClient = httpClient;
        httpClient.getState().setCredentials(AuthScope.ANY, credentials);
    }

    public HttpClient getHttpClient(){
        return httpClient;
    }
}

创建一个 FactoryBean 您自己的类，它返回具有您喜欢的配置的 HttpClient 实例。
