i m getting this error as cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'constructor-arg'. - Security namespace does not support decoration of element [constructor-arg] - Configuration problem: Security namespace does not support decoration of element [constructor-arg] Offending resource: file (project path) how can i solve this errror?

.i want to enocde the password and check if that matches with the database password.

Answer 1

I think the problem because beans is not the default namespace . So you could try

<beans:bean id="passwordEncoder" class="org.springframework.security.authentication.encoding.ShaPasswordEncoder">
 <beans:constructor-arg value="256"/>

or declare beans as default namespace

    <beans xmlns="http://www.springframework.org/schema/beans"
