spring3: schema的aop与Aspectj的aop的区别

schema的aop如下：

接口：

package chapter6.service;
public interface IHelloAroundService {
	public void sayAround(String param);
}

　　接口的实现：

package chapter6.service.impl;
import chapter6.service.IHelloAroundService;
public class HelloAroundService implements IHelloAroundService {
	public void sayAround(String param) {
		// TODO Auto-generated method stub
		System.out.println("========= say around param: " + param);
	}

}

　　aop程序

package chapter6.aop;
import org.aspectj.lang.ProceedingJoinPoint;
public class HelloAroundAspect {
	public Object sayAroundAdvice(ProceedingJoinPoint pjp) throws Throwable
	{
		System.out.println("============= before around advice");
		Object retVal = pjp.proceed(new Object[] {"replace"});
		System.out.println("============= after  around advice");
		return retVal;
	}

}

　　配置文件说明：

<!-- 接口的实现 -->
<bean id="HelloAroundService" class="chapter6.service.impl.HelloAroundService" />
<!-- 切面程序 -->
<bean id="aspect" class="chapter6.aop.HelloAroundAspect" />
<aop:config>
	<!-- 定义插入点 -->
	<aop:pointcut expression="execution(* chapter6..*.sayAround(..))" id="pointcut"/>
	<!-- 通知 -->
	<aop:aspect ref="aspect">
			<aop:around
			pointcut-ref="pointcut"
			method="sayAroundAdvice"/>
	</aop:aspect>
</aop:config>

　　

测试程序大同小异不做展示

Aspectj的aop如下：

接口 ：

package chapter1.server;
public interface IHelloService {

	public void sayAdvisorBefore(String param) ;
}

　　接口实现：

package chapter1.service.impl;

import chapter1.server.IHelloService;

public class HelloService implements IHelloService {	

	public void sayAdvisorBefore(String param) {
		// TODO Auto-generated method stub
		 System.out.println("============say " + param);
	}

}

　　aop程序：

package chapter1.aop;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Before;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class HelloAspect {

	//定义切入点
	@Pointcut(value="execution(* chapter1..*.sayAdvisorBefore(java.lang.String)) && args(param)", argNames = "param")
    public void beforePointcut(String param) {}

	//定义通知
    @Before(value = "beforePointcut(param)", argNames = "param")
    public void beforeAdvice(String param) {
        System.out.println("===========before advice param:" + param);
    }
}

　　配置文件：

<!-- 启动对Aspectj的支持 -->
<aop:aspectj-autoproxy/>
<bean id="helloService" class="chapter1.service.impl.HelloService" />
<bean id="aspect" class="chapter1.aop.HelloAspect"/>

　　

测试程序：

@Test
	public void testAspectj()
	{
		ApplicationContext context = new ClassPathXmlApplicationContext("chapter1/aspectj.xml");
		IHelloService hello = context.getBean("helloService", IHelloService.class);
		hello.sayAdvisorBefore("before");
	}

　　

结果：

===========before advice param:before
============say before
