包中所有方法的AOP

Question

I am using AOP for the first time. I have written the below AOP code which works fine when i use it to intercept a particular method.

Can somebody guide me - how I can set it up to intercept all methods in a certain package (com.test.model)?

Basically how to setup appcontext.xml.

Also, do i need to do something like below to call before calling each method?

AopClass aoptest = (AopClass) _applicationContext.getBean("AopClass");
aoptest.addCustomerAround("dummy");

Can somebody help?

Please let me if some more explanation is needed.

Below is my code:

Interface:

package com.test.model;

import org.springframework.beans.factory.annotation.Autowired;

public interface AopInterface {


    @Autowired
    void addCustomerAround(String name);
}

Class:

package com.test.model;

import com.test.model.AopInterface;
import org.springframework.stereotype.Component;
import org.springframework.beans.factory.annotation.Autowired;

@Component
public class AopClass implements AopInterface {

    public void addCustomerAround(String name){
        System.out.println("addCustomerAround() is running, args : " + name);
    }
}

AOP:

package com.test.model;

import java.util.Arrays;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;



@Aspect
public class TestAdvice{


     @Around("execution(* com.test.model.AopInterface.addCustomerAround(..))")
       public void testAdvice(ProceedingJoinPoint joinPoint) throws Throwable {

        System.out.println("testAdvice() is running!");


       }
}

appcontext:

<!-- Aspect -->
    <aop:aspectj-autoproxy />
    <bean id="AopClass" class="com.test.model.AopClass" />
    <bean id="TestAdvice" class="com.test.model.TestAdvice" />

Just put:

@Around("execution(* com.test.model..*.*(..))")

The format of an execution expression is:

execution(modifiers-pattern? ret-type-pattern declaring-type-pattern? name-pattern(param-pattern) throws-pattern?)

where only ret-type-pattern , name-pattern and param-pattern are required, so at least we need an expression like:

execution(ret-type-pattern name-pattern(param-pattern))

• ret-type-pattern matches the return type, * for any
• name-pattern matches the method name, you can use * as wildcard and .. to indicate sub-package
• param-pattern matches the method parameters, (..) for any number of parameters
