Does Spring AOP use AspectJ?

In Spring AOP, aspects are implemented using regular classes (the schema-based approach) or regular classes annotated with the @Aspect annotation (the @AspectJ style). Join point: a point during the execution of a program, such as the execution of a method or the handling of an exception.

What is the use of AspectJ?

AspectJ Provides a Standard Mechanism to Handle a Crosscutting Concern. In the example shown above, we are doing a null validation and throwing an IllegalArgumentException when the request is null. This way we make sure that whenever an argument is null, we get the same uniform behavior.

What is the difference between AspectJ and Spring AOP?

Spring AOP and AspectJ have different goals. Spring AOP aims to provide a simple AOP implementation across Spring IoC to solve the most common problems that programmers face. On the other hand, AspectJ is the original AOP technology which aims to provide complete AOP solution.

Do you have a namespace declaration in your tag? Something like this:

<beans 
xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop"
...>

I had the same problem and solved it by arranging namespace and schemalocation as below:

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:p="http://www.springframework.org/schema/p"
        xmlns:context="http://www.springframework.org/schema/context"
        xmlns:aop="http://www.springframework.org/schema/aop" 
        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"
        default-destroy-method="destroy"
        default-init-method="afterPropertiesSet"
        default-autowire="byName"
>

Notice that the schemalocation contains both uri:s, the one declared for xmlns:aop and the one for the xsd-file
