aspectj

I want to create Spring aspect which would set method parameter, annotated by custom annotation, to an instance of a particular class identified by an id from URI template. Path variable name is parameter of the annotation. Very similar to what Spring @PathVariable does. So that controller method would look like: @RestController @RequestMapping("/testController") public class TestController { @RequestMapping(value = "/order/{orderId}/delete", method = RequestMethod.GET) public ResponseEntity<?> doSomething( @GetOrder("orderId") Order order) { // do something with order } } Instead of classic:

when i am trying to aspectj with spring using ajc compiler ,i am getting following errror.when i am removing aspectj then code is working fine is there anything with the compile time weaving which is causing problem caused by: java.lang.ExceptionInInitializerError at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java

I have a spring boot application with some REST controllers, service classes and helper classes. The controllers and service classes are spring managed while helper classes are not spring managed and mostly contain static methods. The AspectJ configuration is present in java configuration as follows @Configuration @EnableLoadTimeWeaving(aspectjWeaving = AspectJWeaving.ENABLED) public class AspectConfig { @Bean public LoggingAspect loggingAspect() { return new LoggingAspect(); } } The corresponding LoggingAspect class is as follows, @Aspect public class LoggingAspect { @Before(

I am very new to AspectJ...just started to learn. Till now i am able to get the parameters of user defined method in my aspect and print the captured parameter in my pointcut. Curiously i started to think to print the contents of System.out.println() in my pointcut's advice and written the following simple code: HelloClass.java: public class HelloClass { public static void main(String a[]) { System.out.println("hello sachin"); } } HelloAspect.java: public aspect HelloAspect { pointcut callPointcut(String message ) :call(void java.lang.System.out.println(String))&& args(message); before( String

Given the following example classes in my.package ... public class Foo { public void logicNotInBar() {/*code*/} public void logicBarOverrides() {/*code*/} } public class Bar extends Foo { public void logicBarOverrides() {/*code*/} } and the following Spring-AOP pointcuts... <aop:pointcut id="myPointcutAll" expression="execution(* my.package.*.*(..))" /> <aop:pointcut id="myPointcutFoo" expression="execution(* my.package.Foo.*(..))" /> <aop:pointcut id="myPointcutBar" expression="execution(* my.package.Bar.*(..))" /> What is the result of advice applied to the above pointcuts on instances of

AspectJAwareAdvisorAutoProxyCreator 的类图 上图中一些 类/接口 的介绍： AspectJAwareAdvisorAutoProxyCreator : 公开了AspectJ的调用上下文，并弄清楚来自同一切面的多个Advisor在AspectJ中的优先级规则。 AbstractAdvisorAutoProxyCreator : 通用自动代理创建器，它基于检测到的每个顾问程序为特定bean构建AOP代理。 AbstractAutoProxyCreator : 扩展了 ProxyProcessorSupport，实现了SmartInstantiationAwareBeanPostProcessor、BeanFactoryAware 接口，是BeanPostProcessor 实现，该实现使用AOP代理包装每个合格的bean，并在调用bean本身之前委派给指定的拦截器。 BeanFactoryAware : 实现了该接口的Bean可以知道它属于那个 BeanFactory，Bean可以通过Spring容器查找它的协同者（依赖查找），但大多数的Bean是通过构造器参数和Bean方法（依赖注入）来获取它的协同者。 BeanPostProcessor ：工厂钩子，允许自定义修改新的bean实例。例如，检查标记接口或使用代理包装bean。

My goal is to be able to override what I get back from CustomClass.class.getName() and CustomClass.getClass().getName() It should return a custom value, which I think is best to define in an attribute like @NameOverride("Custom.fully.qualified.class.name") public class CustomClass {} Is there any way to do that? Fred's answer is okay, but his aspect could be somewhat more elegant with less code and especially fewer reflection calls. Sorry, I prefer AspectJ native code style, but @AspectJ annotation style would not be much longer: String around(Class clazz) : call(public String Class.getName())

I'm trying to understand the difference between execution and call in AOP as simply as possible. From what I gather, execution() will add a join point in the executing code, so HelloWorldSayer.sayHello() in this case, but if the pointcut was call() , then the join point will be HelloWorldSayer.main() . Is this correct? public class HelloWorldSayer { public static void main (String[] args) { sayHello(); } public static void sayHello() { System.out.println("Hello"); } } public aspect World { public hello(): execution(static void HelloWorldSayer.sayHello()); after() hello() { System.out.println(
