Spring拦截器的简单例子

Spring拦截器的简单例子 Purview接口: package aop; public interface Purview{ void checkLogin(); } PurviesImpl类(Purview接口的实现类): package aop; public class PurviewImpl implements Purview{ public void checkLogin(){ System.out.println("This is check Login method!"); } } PurviewAdvice类(拦截器类): package aop; import java.lang.reflect.Method; import org.springframework.aop.MethodBeforeAdvice; public class PurviewAdvice implements MethodBeforeAdvice{ public void before(Methodarg0,Object[]arg1,Objectarg2) throws Throwable{ System.out.println("This is before method!"); } } Test类(测试类): package aop; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; public class Test{ public static void main(String[]args){ //TODO自动生成方法存根 ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContext.xml"); Purview purviewImpl=(Purview)ctx.getBean("purviewImpl"); purviewImpl.checkLogin(); } } applicationContext.xml(配置文件): .*checkLogin.* purviewImpl purviewAdvisor 程序运行结果为: This is before method! This is checkLogin method! 至此拦截器使用成功!
