Spring @AspectJ

准备工作:需要 spring/lib/asm 下的3个包:asm.jar asm-commons.jar asm-util.jar
spring/lib/aspectj 下的2个包 aspectjrt.jar 和aspectjweaver.jar
使用@AspectJ的小例子:

public interface Company {

public void descript();

public void ss();

}

public class stockCompany implements Company{

public void descript() {

System.out.print("This is a stock market");

}

//另外添加一个内嵌descript()的函数调用后不会拦截里面的descript函数

public void ss(){

System.out.println("在另外一个函数调用的");

descript();

}

import org.aspectj.lang.annotation.Aspect;

import org.aspectj.lang.annotation.Before;

@Aspect

public class PreDescriptAspect {

@Before("execution(* descript(..))")

public void beforeDescript(){

System.out.print("Here Is My Company Description!");

}

import org.springframework.aop.aspectj.annotation.AspectJProxyFactory;

public class stockCompanyTest {

public static void main(String[] args){

Company target=new stockCompany();

AspectJProxyFactory factory=new AspectJProxyFactory();

factory.setTarget(target);

factory.addAspect(PreDescriptAspect.class);

Company proxy=factory.getProxy();

proxy.descript();

proxy.ss();

}
