createEvaluationContext

public org.springframework.expression.EvaluationContext createEvaluationContext(java.util.function.Supplier<Authentication> authentication,
                                                                                MessageAuthorizationContext<?> message)

Description copied from interface: SecurityExpressionHandler

Provides an evaluation context in which to evaluate security expressions for the invocation type. You can override this method in order to provide a custom implementation that uses lazy initialization of the Authentication object. By default, this method uses eager initialization of the Authentication object.

Specified by:

createEvaluationContext in interface SecurityExpressionHandler<MessageAuthorizationContext<?>>

Parameters:

authentication - the Supplier of the Authentication to use

message - the SecurityExpressionHandler to use

Returns:

the EvaluationContext to use
