我试图创建两个豆LDAP连接。
在我的context.xml文件我创建两个LdapContextSource然后自动线两个bean具有相同的父类,在春天LDAP例子派生类的PersonDao的和PersonDaoImpl。
我不断收到的问题是,无论是豆类结束了相同的上下文源。 即使我使用@Autowired @Qualifier。
调试表明,无论单豆类看到一个不同的LdapContextSource但最终都豆有相同的背景。
有一个例子某处演示如何通过context.xml中和@Autowired方法连线两个LDAP连接?
我可以通过编程方式分配在每个类实例ldapcontextsource,但我想通过@Autowired做到这一点做到这一点而已。
编辑:
为了使这个更清楚我粘贴一些代码样本https://today.java.net/pub/a/today/2006/04/18/ldaptemplate-java-ldap-made-simple.html豆来定义的连接LDAP可被定义为如下:
<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Java类定义为:
public class PersonDaoImpl implements PersonDao {
private LdapTemplate ldapTemplate;
public void setLdapTemplate(LdapTemplate ldapTemplate) {
this.ldapTemplate = ldapTemplate;
}
}
请注意,我定义了两个连接。 一个在端口389 LDAP和一个端口1389。然后我用PersonDaoImpl两次。
这里存在的问题。
该PersonDao2得到389相同的连接PersonDao的不是1389这是假设得到的。
什么可以导致此?

在我看来,有关两行
DEBUG - Added autowiring by name from bean name 'ldapTemplate' via property 'contextSource' to bean named 'contextSource'
和
DEBUG - Added autowiring by name from bean name 'ldapTemplate2' via property 'contextSource' to bean named 'contextSource'
请注意,这两个越来越
via property 'contextSource' to bean named 'contextSource'
该ldapTemplate2应该得到:
via property 'contextSource' to bean named 'contextSource2'
更新:我被要求提供我使用的电线代码到类。
第一种方式是这样的:
@Controller
public class ManageAccountsController{
private PersonDaoImpl personDao2;
}
使用这种方式我没有personDao2的初始化
第二种方式是这样的:
@Controller
public class ManageAccountsController{
@Autowired PersonDaoImpl personDao2;
}
第三种方式是这样的:
@Controller
public class ManageAccountsController{
@Autowired @Qualifier("personDao2") PersonDaoImpl personDao2;
}
最后这2种方法我得到不正确的好的ContextSource。 的PersonDAO的好的ContextSource。
