How can i configure my spring aop xml with aop.xml an load time weaving? - spring

Question

I have one "Hello word" application on spring AOP and configured by XML, it looks like this:
public class CustomerBoImpl {
public CustomerBoImpl() {
super();
}
protected void addCustomer(){
System.out.println("addCustomer() is running ");
}
}
public class App {
public static void main(String[] args) throws Exception {
ApplicationContext appContext =
new ClassPathXmlApplicationContext("Spring-Customer.xml");
CustomerBoImpl customer =
(CustomerBoImpl) appContext.getBean("customerBo");
customer.addCustomer();
}
}
My spring configuration looks like this:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd ">
<aop:aspectj-autoproxy />
<!-- this switches on the load-time weaving -->
<context:load-time-weaver aspectj-weaving="on" />
<bean id="customerBo" class="com.mkyong.saad.CustomerBoImpl"
scope="singleton" />
<!-- Aspect -->
<bean id="logAspect" class="com.mkyong.saad.LoggingAspect" />
<aop:config>
<aop:aspect id="aspectLoggging" ref="logAspect">
<!-- #Before -->
<aop:pointcut id="pointCutBefore"
expression="execution(* com.mkyong.saad.CustomerBoImpl.addCustomer(..))" />
<aop:before method="logBefore" pointcut-ref="pointCutBefore" />
<!-- #After -->
<aop:pointcut id="pointCutAfter"
expression="execution(* com.mkyong.saad.CustomerBoImpl.addCustomer(..))" />
<aop:after method="logAfter" pointcut-ref="pointCutAfter" />
</aop:aspect>
</aop:config>
that doesn't work because of protected method, so I tried to use load time weaving with aop.xml like this:
<?xml version="1.0" encoding="UTF-8"?>
<aspectj>
<weaver>
<!-- only weave classes in our application-specific packages -->
<include within="com.mkyong.saad.*"/>
</weaver>
<aspects>
<!-- weave in just this aspect -->
<aspect name="com.mkyong.saad.LoggingAspect"/>
</aspects>
</aspectj>
Source code for the aspect:
public class LoggingAspect {
public void logBefore(JoinPoint joinPoint) {
System.out.println("logBefore() is running!");
System.out.println("hijacked : " + joinPoint.getSignature().getName());
System.out.println("******");
}
public void logAfter(JoinPoint joinPoint) {
System.out.println("logAfter() is running!");
System.out.println("hijacked : " + joinPoint.getSignature().getName());
System.out.println("******");
}
}
but it doesn't work, only if I change to annotation config. SOS PLZ

removing the following code in your aop.xml, then run your jvm with args like this: -javaagent:"yourpath/spring-instrument-***.jar"
<weaver>
<!-- only weave classes in our application-specific packages -->
<include within="com.mkyong.saad.*"/>
</weaver>
