java – 使用RestTemplate的Spring Security身份验证

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

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);
    }

}

Maven依赖

<dependency>
   <groupId>commons-httpclient</groupId>
   <artifactId>commons-httpclient</artifactId>
   <version>3.1</version>
</dependency>
