我正在尝试为ldap连接创建两个bean。

在我的context.xml文件中，我创建了两个LdapContextSource，然后使用相同的父类自动连接两个bean，这两个bean的派生类似于spring ldap示例中的PersonDao和PersonDaoImpl。

我一直遇到的问题是，两个bean最终都使用相同的上下文源。甚至在我使用@AutoWired@Qualifier之后。

调试显示，两个单例 bean 看到不同的 LdapContextSource，但最终两个 bean 具有相同的上下文。

是否有一个例子，演示如何通过context.xml和@autowed连接两个ldap？

我可以通过在每个类实例中以编程方式分配 ldapcontextsource 来做到这一点，但我正在尝试通过 @AutoWired 来做到这一点。

编辑：

为了更清楚地说明这一点，我从 https://today.java.net/pub/a/today/2006/04/18/ldaptemplate-java-ldap-made-simple.html 粘贴了一些代码示例 定义与 ldap 连接的 bean 可以定义如下：

<beans>
   <context:annotation-config/>
   <context:component-scan base-package="the proper location of my code"/>
   <bean id="contextSource" class="net.sf.ldaptemplate.support.LdapContextSource">
      <property name="url" value="ldap://localhost:389" />
      <property name="base" value="dc=jayway,dc=se" />
      <property name="userName" value="cn=Manager" />
      <property name="password" value="secret" />
  </bean>

   <bean id="ldapTemplate" class="net.sf.ldaptemplate.LdapTemplate">
      <constructor-arg ref="contextSource" />
   </bean>

<bean id="personDao" class="se.jayway.dao.PersonDaoImpl">
    <property name="ldapTemplate" ref="ldapTemplate" />
</bean>

   <bean id="contextSource2" class="net.sf.ldaptemplate.support.LdapContextSource">
      <property name="url" value="ldap://localhost:1389" />
      <property name="base" value="dc=jayway,dc=se" />
      <property name="userName" value="cn=Manager" />
      <property name="password" value="secret" />
  </bean>

   <bean id="ldapTemplate2" class="net.sf.ldaptemplate.LdapTemplate">
      <constructor-arg ref="contextSource2" />
   </bean>

<bean id="personDao2" class="se.jayway.dao.PersonDaoImpl">
    <property name="ldapTemplate" ref="ldapTemplate2" />
</bean>

</beans>

然后将java类定义为:

public class PersonDaoImpl implements PersonDao {
   private LdapTemplate ldapTemplate;

   public void setLdapTemplate(LdapTemplate ldapTemplate) {
      this.ldapTemplate = ldapTemplate;
   }
}

注意，我定义了两个连接。一个用于端口389的ldap，另一个用于1389。然后我使用PersonDaoImpl两次。

问题就在这里。

PersonDao2 在 389 处获得与 PersonDao 相同的连接，而不是它应该获得的 1389。

是什么导致了这种情况？

编辑2:

在我看来，相关的两行是

DEBUG - Added autowiring by name from bean name 'ldapTemplate' via property  'contextSource' to bean named 'contextSource'

然后呢？

DEBUG - Added autowiring by name from bean name 'ldapTemplate2' via property 'contextSource' to bean named 'contextSource'

请注意，这两个都得到了

via property 'contextSource' to bean named 'contextSource'

ldapTemplate2应该得到：

via property 'contextSource' to bean named 'contextSource2'

更新：我被要求提供用于连接到我的类的代码。

第一种方式是这样的：

@Controller
public class ManageAccountsController{
    private PersonDaoImpl personDao2;
}

通过这种方式，我没有初始化personDao2

第二种方法是这样的：

@Controller
public class ManageAccountsController{
    @Autowired PersonDaoImpl personDao2;
}

第三种方法是这样的：

@Controller
public class ManageAccountsController{
    @Autowired @Qualifier("personDao2") PersonDaoImpl personDao2;
}

这最后两个方法我得到了错误的上下文源。人道的语境来源。
