Error creating bean with name 'org.springframework.security.filterChains' Spring + Hibernate + UserDetailService

Question

I just started to learn Spring Security and have some trouble. I want to configure User login on page with password and username which stored in database during registration

Answer 1

 <security:http auto-config="true">

replace this section with the following:

 <security:http auto-config="true" use-expressions="true">

Note:

As a side note i see from the code and from comment i doubt you have injected SessionFactory from GuestBookDAOImpl, thats causes NPE upon method call on the DAO layer. Inject it either from xml config or annotations.

Answer 2

Bean creation error for "org.springframework.security.filterChains" comes when you are using spring version higher than 3.1 and have not added dependencies manually for spring-aop, spring-jdbc, spring-tx and spring-expressions in you POM.xml.

Reason : If don't do so, maven automatically downloads older version jars (3.0.x) for these artifacts which conflict with newer version spring security jars.

Answer 3

use use-expressions="true" along with auto-config="true"

<security:http auto-config="true" use-expressions="true">       
       <security:intercept-url pattern="/user/*" access="hasRole('ROLE_USER')"/> </security:http>
