【问题描述】：

我想公开一个使用 LDAP 进行身份验证的示例 Spring Web 服务。 首先，我创建了网络服务：

import javax.jws.WebMethod;
import javax.jws.WebService;

import com.domain.SampleEntity;

/**
* Actual web service implementation.
* 
*/
@WebService
public class SampleEntityWebService 
    /**
    * Read and return SampleEntity by a supplied id.
    */
    @WebMethod
    public SampleEntityByIdResponse readSampleEntityById(Long id) 
        SampleEntity sampleEntity = new SampleEntity();
        sampleEntity.setId(id);
        SampleEntityByIdResponse sampleEntityByIdResponse = new SampleEntityByIdResponse();
        sampleEntityByIdResponse.setSampleEntity(sampleEntity);
        return sampleEntityByIdResponse;
    

Web Service Provider 配置包含：

    </bean>  

    **<bean id="wsSecurityInterceptor"

        </property>
    </bean>**

    <bean id="authenticationHandler"

                </property>
            </bean>

    </bean> 


    <ws:inbound-gateway id="sampleEntity-by-id-gateway"
        request-channel="sampleEntityRequestById" marshaller="sampleEntityMarshaller"
        unmarshaller="sampleEntityMarshaller" reply-channel="sampleEntityResponse" />

    <int:channel id="sampleEntityRequestById" />
    <int:channel id="sampleEntityResponse" />

    <int:service-activator
        expression="@sampleEntityWebService.readSampleEntityById(payload.id)"
        input-channel="sampleEntityRequestById" output-channel="sampleEntityResponse" requires-reply="true"/>

    <int:channel id="sampleEntitys" />

</beans>

引用的安全策略文件包含：

<xwss:SecurityConfiguration dumpMessages="true" xmlns:xwss="http://java.sun.com/xml/ns/xwss/config"> 
    <xwss:RequireUsernameToken passwordDigestRequired="true" nonceRequired="true"/> 
    </xwss:SecurityConfiguration>

该服务运行良好。现在我想对使用 LDAP 访问此服务的用户进行身份验证。 我是 Spring Web 服务和安全性的新手。谁能建议将 Spring Web 服务与 LDAP 集成所需的配置更改。

【参考方案1】：

您可以将用户详细信息服务从InMemoryDaoImpl 更改为LdapUserDetailsService。

我能推导出的配置是：

<bean id="contextSource"
        class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
  <constructor-arg value="ldap://monkeymachine:389/dc=springframework,dc=org"/>
  <property name="userDn" value="cn=manager,dc=springframework,dc=org"/>
  <property name="password" value="password"/>
</bean>

<bean id="ldapPopulator" class="org.springframework.security.ldap.userdetails.DefaultLdapAuthoritiesPopulator">
   <constructor-arg ref="contextSource"/>
   <constructor-arg value="ou=groups"/>
   <property name="groupRoleAttribute" value="ou"/>
</bean>

<bean id="userSearch"
    class="org.springframework.security.ldap.search.FilterBasedLdapUserSearch">
    <constructor-arg index="0"
        value="ou=People,o=MyCompany,o=Intranet" />
    <constructor-arg index="1" value="(uid=0)" />
    <constructor-arg index="2" ref="contextSource" />
</bean>

<bean id="authenticationHandler" class="org.springframework.ws.soap.security.xwss.callback.SpringDigestPasswordValidationCallbackHandler">
      <property name="userDetailsService">
        <bean class="org.springframework.security.ldap.userdetails.LdapUserDetailsService">
             <constructor-arg ref="userSearch">
             <constructor-arg ref="ldapPopulator">
        </bean>
      </property> 
</bean> 

请记住，我还没有尝试过，而且大部分部分都是我从其他来源复制的。您需要的是UserDetailsService，您只需将其设置为authenticationHandler。从LdapUserDetailsService 源代码来看，它需要两个构造函数，LdapUserSearch 和LdapAuthoritiesPopulator。我搜索了一个关于如何实例化LdapUserSearch bean 的示例，并从here 中找到了示例。我从官方文档中找到了 LdapPopulator bean 示例。

有关使用 Spring Security 的 Ldap 身份验证的更多详细信息，请访问official documentation。

希望您了解 LDAP，因为我对 LDAP 一无所知。祝你好运。
