Class MethodSecurityMetadataSourceAdvisor

java.lang.Object

org.springframework.aop.support.AbstractPointcutAdvisor

org.springframework.security.access.intercept.aopalliance.MethodSecurityMetadataSourceAdvisor

All Implemented Interfaces:

Serializable, Advisor, PointcutAdvisor, Aware, BeanFactoryAware, Ordered

public class MethodSecurityMetadataSourceAdvisor
extends AbstractPointcutAdvisor
implements BeanFactoryAware

Advisor driven by a MethodSecurityMetadataSource, used to exclude a MethodSecurityInterceptor from public (non-secure) methods.

Because the AOP framework caches advice calculations, this is normally faster than just letting the MethodSecurityInterceptor run and find out itself that it has no work to do.

This class also allows the use of Spring's DefaultAdvisorAutoProxyCreator, which makes configuration easier than setup a ProxyFactoryBean for each object requiring security. Note that autoproxying is not supported for BeanFactory implementations, as post-processing is automatic only for application contexts.

Based on Spring's TransactionAttributeSourceAdvisor.

Constructor Detail

MethodSecurityMetadataSourceAdvisor

public MethodSecurityMetadataSourceAdvisor(String adviceBeanName,
                                           MethodSecurityMetadataSource attributeSource,
                                           String attributeSourceBeanName)

Alternative constructor for situations where we want the advisor decoupled from the advice. Instead the advice bean name should be set. This prevents eager instantiation of the interceptor (and hence the AuthenticationManager). See SEC-773, for example. The metadataSourceBeanName is used rather than a direct reference to support serialization via a bean factory lookup.

Parameters:

adviceBeanName - name of the MethodSecurityInterceptor bean

attributeSource - the SecurityMetadataSource (should be the same as the one used on the interceptor)

attributeSourceBeanName - the bean name of the attributeSource (required for serialization)
