acegi的MethodSecurityInterceptor实现


AfterInvocationProviderImp

package com.bulain.test;

import org.acegisecurity.AccessDeniedException;
import org.acegisecurity.Authentication;
import org.acegisecurity.ConfigAttribute;
import org.acegisecurity.ConfigAttributeDefinition;
import org.acegisecurity.afterinvocation.AfterInvocationProvider;
import org.aopalliance.intercept.MethodInvocation;
import org.apache.log4j.Logger;

public class AfterInvocationProviderImp implements AfterInvocationProvider {
	private static Logger logger = Logger.getLogger(AfterInvocationProviderImp.class);

	public Object decide(Authentication authentication, Object object, ConfigAttributeDefinition config, Object returnedObject)
			throws AccessDeniedException {
		return returnedObject;
	}

	public boolean supports(ConfigAttribute attribute) {
		logger.info("ConfigAttribute: " + attribute);
		if (attribute.getAttribute().equals("BANKSECURITY_CUSTOMER")) {
			return true;
		}
		return false;
	}

	public boolean supports(Class clazz) {
		logger.info("Class: " + clazz);
		if (clazz == MethodInvocation.class) {
			return true;
		}
		return false;
	}

}

ApplicationEventPublisherImp

package com.bulain.test;

import org.apache.log4j.Logger;
import org.springframework.context.ApplicationEvent;
import org.springframework.context.ApplicationEventPublisher;

public class ApplicationEventPublisherImp implements ApplicationEventPublisher {
	private static Logger logger = Logger.getLogger(ApplicationEventPublisherImp.class);

	public void publishEvent(ApplicationEvent event) {
		logger.info("publishEvent: " + event);
	}

}

BankManager

package com.bulain.test;

public interface BankManager {
	/**
	 * Delete something
	 */
	public void deleteSomething(int id);
	
	/**
	 * Delete another
	 */
	public void deleteAnother(int id);
	
	/**
	 * Get balance
	 */
	public float getBalance(int id);
}

BankManagerImp

package com.bulain.test;

import org.apache.log4j.Logger;

public class BankManagerImp implements BankManager {
	private static Logger logger = Logger.getLogger(BankManagerImp.class);

	public void deleteSomething(int id) {
		logger.info("deleteSomething()");
	}

	public void deleteAnother(int id) {
		logger.info("deleteAnother()");
	}

	public float getBalance(int id) {
		logger.info("getBalance()");
		return 0;
	}
}

BankManagerImpTest

	private static void createSecureContext(final BeanFactory bf, final String username, final String password) {
		AuthenticationProvider provider = (AuthenticationProvider) bf.getBean("daoAuthenticationProvider");
		Authentication auth = provider.authenticate(new UsernamePasswordAuthenticationToken(username, password));
		SecurityContextHolder.getContext().setAuthentication(auth);
	}

	// Clear the security context after each test.
	public void teardown() {
		SecurityContextHolder.setContext(new SecurityContextImpl());
	}

	public static void main(String[] args) {

	}

	/*
