Spring AOP - AspectJ - @Around example

Last few pages talked about spring advices (before advice, after return advice, around advice and pointcut examples). In this page you will get an idea about how to integrate AspectJ annotations with Spring AOP framework. Using spring AOP and AspectJ, you can easily intercept methods.

AspectJ comes with below annotations:

1) @Before
2) @After
3) @AfterReturning
4) @AfterThrowing
5) @Around

In this page we will see an example for @Around annotation. @Around annotation intercepts method before and after calling it.

pom.xml file gives all required dependencies: Add dependencies for spring-aop jar, aspectjrt jar and aspectjweaver jar file.

<project xmlns="" 

My business logic service class:

package com.java2novice.bean;

public class MyBusinessService {

        public String runMyBusinessLogic(){
                System.out.println("Running business logic...");
                return "Successfully executed my business logic";
        public void testThrowException() {
                throw new NullPointerException();

Here is the Aspect class example. The invoke() method will be called before executing runMyBusinessLogic() method. Also you have to define joinPoint.proceed() to control when should the interceptor return the control to the original calling method runMyBusinessLogic().

package com.java2novice.aop;

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

public class ExecuteAroundMethod {

        @Around("execution(* com.java2novice.bean.MyBusinessService.runMyBusinessLogic(..))")
        public Object invoke(ProceedingJoinPoint joinPoint) throws Throwable {
                System.out.println("Inside RunBeforeExecution.before() method...");
                System.out.println("Running before advice...");
                        Object result = joinPoint.proceed();
                        System.out.println("Inside RunAfterExecution.afterReturning() method...");
                        System.out.println("Running after advice...");
                        return result;
                } catch(Exception ne){
                        throw ne;

Here is the xml based configuration file. By adding "<aop:aspectj-autoproxy />" tag, you can enable AspectJ with in your application. Add bean definitions for your normal bean and your Aspect.

<beans xmlns=""
    <aop:aspectj-autoproxy />
    <bean id="busService" class="com.java2novice.bean.MyBusinessService" />
        <bean id="afterThrowAspectBean" class="com.java2novice.aop.ExecuteAroundMethod" />

Here is the final demo class:

package com.java2novice.test;

import org.springframework.context.ConfigurableApplicationContext;

import com.java2novice.bean.MyBusinessService;

public class SpringDemo {

        public static void main(String a[]){

                String confFile = "applicationContext.xml";
                ConfigurableApplicationContext context = 
                                                new ClassPathXmlApplicationContext(confFile);
                MyBusinessService busServ = (MyBusinessService) context.getBean("busService");

Inside RunBeforeExecution.before() method...
Running before advice...
Running business logic...
Inside RunAfterExecution.afterReturning() method...
Running after advice...

What is fail-fast in java?
A fail-fast system is nothing but immediately report any failure that is likely to lead to failure. When a problem occurs, a fail-fast system fails immediately. In Java, we can find this behavior with iterators. Incase, you have called iterator on a collection object, and another thread tries to modify the collection object, then concurrent modification exception will be thrown. This is called fail-fast.
