Error creating bean with name 'securityConfig': Injection of autowired dependencies failed

Question

I am trying to combine Java-config and xml-config for spring security authentication. But i received an error:

Error creating bean with name 'securityConfig': Injection of autowired dependencies failed

What seems to be the problem with my code? Been googling for answers but have not found any.

Thanks in advance. hope you can help me.

i have already declared component-scanning in my servlet-context.xml

<context:component-scan base-package="ph.project.p3.conf" />

Answer 1

You could try adding a @Component annotation. That way the autowiring should work.

Answer 2

You need to add <context:component-scan> in Spring-config file. Otherwise your application will not scan your package structure to find and register beans within application context.

Syntax: <context:component-scan base-package="org.example.<yourapplicationName>"/> Eg: <context:component-scan base-package="oph.project.p3.conf"/>
