RestTemplate với Auth cơ bản trong mùa xuân 3.1

Question

Chúng tôi đã sử dụng RestTemplate với cấu hình xml trong Spring 3.0 và nó hoạt động hoàn toàn tốt.

<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> 

Tuy nhiên, khi chúng tôi đang cố gắng để di chuyển đến Học Kỳ Mùa Xuân lớp CommonsClientHttpRequestFactory 3.1 phát hành bị phản đối và cũng commons HttpClient không được sử dụng nữa.

Tôi đã cố gắng thiết lập cấu hình tương tự bằng cách sử dụng lớp HttpComponentsClientHttpRequestFactory và Apache HttpClient, nhưng không nhận được cách tôi có thể đặt Nhà cung cấp thông tin xác thực.

Chúng tôi muốn httpnhient có xác thực cơ bản. Có ai thực hiện điều này hay bất kỳ con trỏ nào sẽ giúp ích rất nhiều. Cảm ơn trước.

Tôi cuối cùng cũng có thể làm việc này. Bạn không chắc chắn liệu nó có tối ưu hay không, vì đây là giải pháp đầu tiên làm việc cho tôi.

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

tôi có thể làm việc này ra với Spring 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"> 
     <constructor-arg ref="httpClient" /> 
    </bean> 

    <bean id="httpClient" factory-bean="httpClientBuilder" factory-method="build" /> 

    <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 
    provider and credentials in constructor or setter method. It has to set by invoking setCredentials() method and passing two arguments --> 
    <bean id="methodInvoke" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean"> 
     <property name="targetObject" ref="credentialProvider" /> 
     <property name="targetMethod" value="setCredentials" /> 
     <property name="arguments" > 
      <list> 
       <ref bean="authScope" /> 
       <ref bean="credentials" /> 
      </list> 
     </property> 
    </bean> 

    <!-- Authorization scope for accessing restful service. Since we want this template to be used for everything, we are setting up it with defaults --> 
    <bean id="authScope" class="org.apache.http.auth.AuthScope"> 
     <constructor-arg name="host"><null /></constructor-arg> 
     <constructor-arg><value>-1</value> </constructor-arg> 
     <constructor-arg><null /></constructor-arg> 
     <constructor-arg><null /></constructor-arg> 
    </bean>
