應用服務器啟動時的Spring Security LDAP配置BeanCreationException

Question

我正在嘗試將Spring 3.1應用程序連接到內部Zimbra LDAP服務器。 我正在做某事，可能非常愚蠢，看不到問題所在。 我確定我定義的組和用戶群以及過濾器術語可能存在問題，但這不應該在應用服務器啟動時引起BeanCreationException，不是嗎？ 我可以用另一雙眼睛...

例外的簡短版本：

“無法將LdapAuthenticationProvider轉換為屬性提供者[0]的必需類型AuthenticationProvider。”

完整的例外：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authentication.ProviderManager#0': Cannot create inner bean '(inner bean)' of type [org.springframework.security.config.authentication.AuthenticationManagerFactoryBean] while setting bean property 'parent'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#16': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.authenticationManager': Initialization of bean failed; nested exception is org.springframework.beans.ConversionNotSupportedException: Failed to convert property value of type 'java.util.ArrayList' to required type 'java.util.List' for property 'providers'; nested exception is java.lang.IllegalStateException: Cannot convert value of type [org.springframework.security.ldap.authentication.LdapAuthenticationProvider] to required type [org.springframework.security.authentication.AuthenticationProvider] for property 'providers[0]': no matching editors or conversion strategy found

相關的Spring配置文件條目：

<security:authentication-manager>
    <security:ldap-authentication-provider
        group-search-filter="member={0}"
        group-search-base="ou=groups"
        user-search-base="ou=people"
        user-search-filter="uid={0}"
    />        
</security:authentication-manager>

<security:ldap-server url="ldap://<correct IP and port>" manager-dn="uid=zimbra,cn=admins,cn=zimbra" manager-password="<private>" />

感謝您提供的任何見解！

看來您所包含的Spring庫之間不匹配。 您需要確保您的Spring Security LDAP庫與其他Spring Security庫版本匹配。

例如：

spring-security-web-3.1.0.RELEASE.jar
spring-security-core-3.1.0.RELEASE.jar
spring-security-config-3.1.0.RELEASE.jar
spring-security-ldap-3.1.0.RELEASE.jar
