在Spring 3.1中使用Basic Auth进行RestTemplate [英] RestTemplate with Basic Auth in Spring 3.1

问题描述

我们在Spring 3.0中使用RestTemplate和xml配置，它运行得很好。

We were using RestTemplate with xml configuration in Spring 3.0 and it was working perfectly fine.

<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>

但是，当我们尝试迁移到Spring 3.1时，CommonsClientHttpRequestFactory类已被弃用，而且公共HttpClient也是不再使用。

But, when we are trying to migrate to Spring 3.1 release CommonsClientHttpRequestFactory class is deprecated and also commons HttpClient is not used anymore.

我试图使用HttpComponentsClientHttpRequestFactory类和Apache HttpClient设置类似的配置，但没有得到如何设置凭据提供程序。

I was trying to set up similar config using HttpComponentsClientHttpRequestFactory class and Apache HttpClient, but not getting how can I set the Credential Provider.

我们希望httpclient具有基本身份验证。有没有人这样做或任何指针将是很大的帮助。在此先感谢。

We want the httpclient with basic auth. Has anybody done this or any pointers would be great help. Thanks in Advance.

推荐答案

我终于得到了这个工作。不确定它是否是最佳的，因为这是第一个适合我的解决方案。

I was able to finally get this working. Not sure whether it is optimal, as this the first solution which worked for me.

<!-- Credentials provider needed by apache default http client -->
<bean id="credentialProvider" class="org.apache.http.impl.client.BasicCredentialsProvider" />

<!-- 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 local="credentialProvider" /> </property>
    <property name="targetMethod" value="setCredentials"> </property>
    <property name="arguments"  >
        <list>
            <ref local="authScope" />
            <ref local="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>

<!-- Username and Password Credentials to access restful service -->
<bean id="credentials" class="org.apache.http.auth.UsernamePasswordCredentials">
    <constructor-arg name="userName"><value>xxx</value></constructor-arg>
    <constructor-arg name="password"><value>xxx</value></constructor-arg>
</bean>

<!-- Client factory which uses Apache HttpClient implementation.  Note that it DO NOT use apache commons httpclient -->
<bean id="httpClientFactory" class="org.springframework.http.client.HttpComponentsClientHttpRequestFactory"> 
    <constructor-arg ref="httpClient"/> 
</bean>

<bean id="httpClient" class="org.apache.http.impl.client.DefaultHttpClient">
    <property name="credentialsProvider" ref="credentialProvider"/>
</bean>

<!-- Rest template for Spring 3.1. Used HttpClientFactory to make request -->
  <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>`
