我有2个
Spring Web应用程序,提供2个单独的服务. Web App 1具有使用基于用户身份验证的Spring Security实现.
现在,Web App 2需要访问Web App 1的服务.通常,我们将使用RestTemplate类向其他Web服务发出请求.
我们如何将Web App 2的请求中的认证凭证传递给Web App 1
解决方法
我处于同样的境地.这里有我的解决方案
服务器 – 弹簧安全配置
<sec:http>
<sec:intercept-url pattern="/**" access="ROLE_USER" method="POST"/>
<sec:intercept-url pattern="/**" filters="none" method="GET"/>
<sec:http-basic />
</sec:http>
<sec:authentication-manager alias="authenticationManager">
<sec:authentication-provider>
<sec:user-service>
<sec:user name="${rest.username}" password="${rest.password}" authorities="ROLE_USER"/>
</sec:user-service>
</sec:authentication-provider>
</sec:authentication-manager>
客户端RestTemplate配置
<bean id="httpClient" class="org.apache.commons.httpclient.HttpClient">
<constructor-arg ref="httpClientParams"/>
<property name="state" ref="httpState"/>
</bean>
<bean id="httpState" class="CustomHttpState">
<property name="credentials" ref="credentials"/>
</bean>
<bean id="credentials" class="org.apache.commons.httpclient.UsernamePasswordCredentials">
<constructor-arg value="${rest.username}"/>
<constructor-arg value="${rest.password}"/>
</bean>
<bean id="httpClientFactory" class="org.springframework.http.client.CommonsClientHttpRequestFactory">
<constructor-arg ref="httpClient"/>
</bean>
<bean class="org.springframework.web.client.RestTemplate">
<constructor-arg ref="httpClientFactory"/>
</bean>
自定义HttpState实现
/**
* Custom implementation of {@link HttpState} with credentials property.
*
* @author banterCZ
*/
public class CustomHttpState extends HttpState {
/**
* Set credentials property.
*
* @param credentials
* @see #setCredentials(org.apache.commons.httpclient.auth.AuthScope,org.apache.commons.httpclient.Credentials)
*/
public void setCredentials(final Credentials credentials) {
super.setCredentials(AuthScope.ANY,credentials);
}
}
