RestTemplate con Basic Auth in primavera 3.1

Question

Stavamo usando RestTemplate con la configurazione xml in Spring 3.0 e funzionava perfettamente.

<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> 

Ma, quando stiamo cercando di migrare alla primavera versione 3.1 classe CommonsClientHttpRequestFactory è deprecato e anche comuni HttpClient non è più utilizzato.

Stavo cercando di configurare una configurazione simile usando la classe HttpComponentsClientHttpRequestFactory e Apache HttpClient, ma non ottenendo come posso impostare il Provider di credenziali.

Vogliamo il httpclient con l'autenticazione di base. Qualcuno ha fatto questo o qualsiasi suggerimento sarebbe di grande aiuto. Grazie in anticipo.

Sono riuscito finalmente a farlo funzionare. Non sono sicuro se sia ottimale, in quanto questa è la prima soluzione che ha funzionato per me.

<!-- Credentials provider needed by apache default http client -->

io sono in grado di lavorare questo fuori con la Primavera 4 RestTemplate

<bean id="restTemplate" class="org.springframework.web.client.RestTemplate"> 
     <constructor-arg ref="httpClientFactory" /> 
    </bean> 

    <bean id="httpClientFactory" class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory">

    <bean id="httpClientBuilder" class="org.apache.http.impl.client.HttpClientBuilder" factory-method="create"> 
     <property name="defaultRequestConfig" ref="requestConfig" /> 
     <property name="defaultCredentialsProvider" ref="credentialProvider"/> 
    </bean> 

    <bean id="requestConfig" factory-bean="requestConfigBuilder" factory-method="build" /> 

    <bean id="requestConfigBuilder" class="org.apache.http.client.config.RequestConfig" factory-method="custom"> 
     <property name="socketTimeout" value="${MILLISEC`enter code here`ONDS}" /> 
     <property name="connectTimeout" value="${MILLISECONDS}" /> 
    </bean> 

<bean id="credentials" class="org.apache.http.auth.NTCredentials"> 
     <constructor-arg value="${USER}" /> 
     <constructor-arg value="${PASSWORD}" /> 
     <constructor-arg value="" /> 
     <constructor-arg value="${DOMAIN}" /> 
    </bean> 

    <bean id="credentialProvider" class="org.apache.http.impl.client.BasicCredentialsProvider" /> 

    <!-- This is used to invoke a method in BasicCredentialsProvider. This has to be done this way as BasicCredentialsProvider does not take
