How to configure AOP in Spring -

How to configure AOP in Spring -

i haven't used aop before in spring before, i"m trying simple illustration working application.

this code used:

/** * product cache aspect manages product cache. * */ @aspect public class productcacheaspect { private static logger logger = logmanager.getlogger(productcacheaspect.class.getname()); @autowired private memcachedclient memcachedclient; @afterreturning( pointcut = "execution(* com.ideafactory.mvc.products.common.services.productservice.get(..))", returning= "result") public void logafterreturning(joinpoint joinpoint, object result) { logger.debug("executed point cut"); logger.debug(result); } }

and think have configured correctly:

@configuration @componentscan(basepackages = {"com.ideafactory"}) @propertysource(value = {"classpath:application.properties"}) @enablescheduling **@enableaspectjautoproxy** @enablecaching @enabletransactionmanagement public class appconfig { ... }

i have pom.xml set import aspectj.

but when seek execute method on productservice, doesn't come in aspect method. i'm not sure how troubleshoot now.

can suggest wrong?

========== method beingness advised =============

@override @transactional(readonly = true, rollbackfor = exception.class) public product get(long productid) { logger.entry(); product product = null; // check cache first, if it's in cache we'll utilize that. product = (product) memcachedclient.get(product.getcachekey(productid)); if (product == null) { product = productrepository.findone(productid); // initialise product. if (product != null) { hibernate.initialize(product.getimagesets()); hibernate.initialize(product.gettags()); hibernate.initialize(product.getvariantoptions()); hibernate.initialize(product.getvariants()); hibernate.initialize(product.getchildrelationships()); memcachedclient.set(product.getcachekey(productid), 3600, product); } } logger.exit(); homecoming product; }

=========== class definition =============

package com.ideafactory.mvc.products.common.services; @service public class productserviceimpl implements productservice { ... }

============ adding pom.xml =================

your pointcut trying advise interface execution iirc not possible (ie: interface not code executed). should advising implementation. additionally, suggested @angad, may need annotate @component such spring autoscans (unless have custom auto observe filter). not believe spring automatically detect/instantiate @aspect beans.

so have couple of options.

1: build pointcut advise implementation itself:

@afterreturning( pointcut = "execution(* com.ideafactory.mvc.products.common.services.productserviceimpl.get(..))", returning= "result") public void logafterreturning(joinpoint joinpoint, object result) { logger.debug("executed point cut"); logger.debug(result); }

2: write pointcut advise interface , classes implement (note + symbol @ end of interface name):

@afterreturning( pointcut = "execution(* com.ideafactory.mvc.products.common.services.productservice+.get(..))", returning= "result") public void logafterreturning(joinpoint joinpoint, object result) { logger.debug("executed point cut"); logger.debug(result); }
