Simple AOP Not Working

[cmaksymchuk]

Good Morning Everyone,

I am trying to get a simple aop app to work but it seems as if spring is ignoring the aop part of my spring-config file. Not sure what I'm doing wrong.

Here is what I have:
1) A simple interface and implementing class
2) A pojo aspect class
3) A class to test it
4) My spring config.xml

 
//==========================================
 
package com.macdon.aop.logging.test;
public interface IService {
	Object doSomething(String obj,int i);	
	void doException() throws Throwable;
}
 
//==========================================
 
package com.macdon.aop.logging.test;
public class ServiceImpl implements IService{
	public Object doSomething(String obj, int i) {
		System.err.println(obj + i);
		return obj;
	}
	public void doException() throws Throwable {
		throw new Exception("Thrown exception");
	}
}
 
//==========================================
 
package com.macdon.aop.logging;
public class TestAspect {
  public TestAspect() {}  
  public void foo() {
    System.out.println("===== This got injected =====");
  }
}
 
//==========================================

	<bean id="fooService" class="com.macdon.aop.logging.test.ServiceImpl" />  
  <bean id="testerid" class="com.macdon.aop.logging.TestAspect" />
  
  <aop:config>      
    <aop:aspect ref="testerid">        
    <aop  ointcut id="all" expression="execution(* *.*(..))" />
      <aop:before method="foo" pointcut="execution(* *.*(..))" />
      <aop:before           method="foo" pointcut-ref="all"/>
      <aop:after-returning  method="foo" pointcut-ref="all" />
      <aop:after-throwing   method="foo" pointcut-ref="all" />      
    </aop:aspect>
  </aop:config>
</beans>

I get output:

Testing 123
java.lang.Exception: Thrown exception at com.macdon.aop.logging.test.ServiceImpl.doExceptio n(ServiceImpl.java:17)
at com.macdon.aop.logging.test.TestLogger.main(TestLo gger.java:19)

But no aop behavior.

Can someone please help?

Thanks so much.

As answered numerous times use an ApplicationContext implementation. In your case ClassPathXmlApplicationContext. Chapter 3.8 of the reference guide explains the differences between a BeanFactory and an ApplicationContext.
