Spring 3.0ではxml構成でRestTemplateを使用していましたが、完全に正常に機能していました。

<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>

ただし、Spring 3.1リリースに移行しようとすると、CommonsClientHttpRequestFactoryクラスは非推奨になり、commonsHttpClientも使用されなくなります。

HttpComponentsClientHttpRequestFactoryクラスとApacheHttpClientを使用して同様の構成をセットアップしようとしましたが、資格情報プロバイダーを設定する方法がわかりません。

基本認証付きのhttpclientが必要です。誰かがこれをしたか、または何かポインタが大きな助けになるでしょう。前もって感謝します。

私はついにこれを機能させることができました。これが私のために働いた最初の解決策であるため、それが最適であるかどうかはわかりません。
