Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to avoid type ambiguities)

Question

I am getting this exception when migrating Spring security version 3 to 4. I am implementing it using Sprig 4 XML based security. Your will be really appreciated

Exception:

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'util:list#f1d6071': Cannot create inner bean 'security:filter-chain#1c5c0deb' of type [org.springframework.security.web.DefaultSecurityFilterChain] while setting bean property 'sourceList' with key [10]; nested exception is org.springframework.beans.factory.Bea nCreationException: Error creating bean with name 'security:filter-chain#1c5c0deb': Cannot resolve reference to bean 'adminConsoleDeniedExceptionTranslationFilter' while setting co nstructor argument with key [5]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'adminConsoleDeniedExceptionTranslationF ilter' defined in ServletContext resource [/WEB-INF/spring-security.xml]: Could not resolve matching constructor (hint: specify index/type/name arguments for simple parameters to a void type ambiguities)

Answer 1

Name attribute in first constructor-arg (of bean adminConsoleDeniedExceptionTranslationFilter) has weird value authenticationEntryPoint2:

<bean id="adminConsoleDeniedExceptionTranslationFilter" class="org.springframework.security.web.access.ExceptionTranslationFilter">
    <constructor-arg name="authenticationEntryPoint2" ref="preAuthenticatedProcessingFilterEntryPoint"/>
    <constructor-arg ref="adminConsoleAccessDeniedHandler"/>
</bean>

It should be authenticationEntryPoint according documentation.

And else, second constructor-arg has no name attribute. Consider either to add name attribute, or remove both.
