| 30 | * Advisor driven by a {@link MethodDefinitionSource}, used to exclude a {@link | |
| 31 | * MethodSecurityInterceptor} from public (ie non-secure) methods. | |
| 32 | * | |
| 33 | * <p> | |
| 34 | * Because the AOP framework caches advice calculations, this is normally | |
| 35 | * faster than just letting the <code>MethodSecurityInterceptor</code> run and | |
| 36 | * find out itself that it has no work to do. | |
| 37 | * </p> | |
| 38 | * | |
| 39 | * <p> | |
| 40 | * This class also allows the use of Spring's | |
| 41 | * <code>DefaultAdvisorAutoProxyCreator</code>, which makes configuration | |
| 42 | * easier than setup a <code>ProxyFactoryBean</code> for each object requiring | |
| 43 | * security. Note that autoproxying is not supported for BeanFactory | |
| 44 | * implementations, as post-processing is automatic only for application | |
| 45 | * contexts. | |
| 46 | * </p> | |
| 47 | * | |
| 48 | * <p> | |
| 49 | * Based on Spring's TransactionAttributeSourceAdvisor. | |
