[SPRING] 스프링 3.1에서 기본 인증을 사용하여 RestTemplate

스프링 3.1에서 기본 인증을 사용하여 RestTemplate

우리는 Spring 3.0에서 RestTemplate을 xml 구성과 함께 사용하고 있었고 완벽하게 작동했습니다.

<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" name="restTemplate" class="org.springframework.web.client.RestTemplate" autowire-candidate="true">
        <constructor-arg ref="httpClientFactory" />

    <property name="messageConverters"> 
        <list> 
            <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
            </bean> 
            <bean class="org.springframework.http.converter.FormHttpMessageConverter"/> 
            <bean class="org.springframework.http.converter.StringHttpMessageConverter" />
        </list> 
    </property>
  </bean>

그러나 Spring 3.1 릴리스로 마이그레이션하려고 할 때 CommonsClientHttpRequestFactory 클래스는 더 이상 사용되지 않으며 커밋 HonspClient는 더 이상 사용되지 않습니다.

HttpComponentsClientHttpRequestFactory 클래스와 Apache HttpClient를 사용하여 유사한 설정을 설정하려했지만 Credential Provider를 설정하는 방법을 알지 못했습니다.

기본 인증을 사용하여 httpclient를 원합니다. 아무도 이것을 한 적이 없거나 어떤 포인터가 큰 도움이 될 수 있습니다. 미리 감사드립니다.
