But i couldnt do same for repositories. i have been struggling for 2 days and i tried so many things for fix it. i read almost every docs, issues and threads about this( proxy issues CGlib and JDK Proxy etc). i used jhipster for creating project.

AspectJ pointcut to method call in specific methods

给你一囗甜甜゛ 提交于 2019-12-05 06:53:29
I want to create a pointcut to target a call to a method from specific methods. take the following: class Parent { public foo() { //do something } } class Child extends Parent { public bar1() { foo(); } public bar2() { foo(); } public bar3() { foo(); } } I would like to have a point cut on the call to foo() in methods bar1() and bar3() I was thinking something like pointcut fooOperation(): call(public void Parent.foo() && (execution(* Child.bar1()) || execution(* Child.bar3()) ); before() : fooOperation() { //do something else } however, that doesnt seem to work. any ideas? thanks Maybe

What do .. and * mean in aspectj

倾然丶 夕夏残阳落幕 提交于 2019-12-05 06:38:50
My understanding is that .. is 0-Many args and * is one arg of any name. Is this correct? Does aspectj support syntax like args(..,myArg,..) ? This is from AspectJ site: http://www.eclipse.org/aspectj/doc/next/progguide/semantics-pointcuts.html * represents any number of characters except "." .. represents any number of characters including any number of "." Update From AspectJ in Action - for method signatures: In method signatures, the wildcard .. is used to denote any type and number of arguments taken by a method * specifies a single argument Others have answered part of the question

Is it possible to integrate Dagger and AspectJ in an Android Studio project?

吃可爱长大的小学妹 提交于 2019-12-05 05:40:23
I'm working in an Android project where I'm using Dagger for dependency injection. I don't know so much about Gradle, but as far as I understand, the Dagger annotations are processed by its compiler once the project is built. There's no problem in configuring it as the user guide says. Well, now I want to integrate AspectJ too, so I'm looking at one of the plugins for Android . However, it seems this plugin does a build post processing job to read the aspects too, which remains in conflict with what Dagger compiler does. That's my current build.gradle file (Built a test project to have a SSCCE

Spring AOP: @annotation(annotation)

拜拜、爱过 提交于 2019-12-05 03:45:35
I am (of course) trying to maintain a project using many constructs I don't know that well. In the course of attempting to figure out the AOP use within Spring, I came across methods with the following annotation: @Around(value = "@annotation(annotation)") So @Around means we're doing the 'around' version of the method pointcut in AOP, I understand that. I don't know what the other part means. The Spring documentation gives the following: @annotation - limits matching to join points where the subject of the join point (method being executed in Spring AOP) has the given annotation I don't know

@EnableAspectJAutoProxy does not work

I am using Spring Boot, and I would like to use AspectJ with it. The following works (of course): @Aspect @Component public class RequestMappingAspect { @Before("@annotation(org.springframework.web.bind.annotation.RequestMapping)") public void advice(JoinPoint joinPoint) { ... } } However, if @Component is removed and @EnableAspectJAutoProxy is added, the following does not work. @SpringBootApplication @EnableSwagger2 @EnableAspectJAutoProxy public class Application { public static void main(String[] args) { SpringApplication.run(Application.class, args); } } How to enable AspectJ auto proxy

Spring AOP 切面编程记录日志和接口执行时间

最近客户现在提出系统访问非常慢,需要优化提升访问速度,在排查了nginx、tomcat内存和服务器负载之后,判断是数据库查询速度慢,进一步排查发现是因为部分视图和表查询特别慢导致了整个系统的响应时间特别长。知道了问题之后,就需要对查询比较慢的接口进行优化,但哪些接口需要优化、哪些不需要呢?只能通过日志里的执行时间来判断,那么如何才能知道每一个接口的执行时间呢? 如果想学习Java工程化、高性能及分布式、深入浅出。微服务、Spring,MyBatis,Netty源码分析的朋友可以加我的Java高级交流:854630135,群里有阿里大牛直播讲解技术,以及Java大型互联网技术的视频免费分享给大家。 对于这个问题,想到了使用动态代理的方式统一记录方法的执行时间并打印日志,这样就能很直观、方便的看到每个接口的执行时间了。 由于使用的是spring框架,对象都是由spring统一管理的,所以最后使用的是 Spring AOP 切面编程来统一记录接口的执行时间,具体代码如下(基于注解的方式): @Component @Aspect public class AopLoggerAspect { private static final Logger logger = Logger.getLogger(AopLoggerAspect.class); @Pointcut("execution

AspectJ: two kinds of tutorials

天涯浪子 提交于 2019-12-05 02:22:14
From my research I know there are two ways of using AspectJ. First is by creating A.aj class and second by adding annotation @Aspect in A.java . I was looking for a good tutorial for this second kind, especially about lines like @After("call(void fooMethod())") @Around("call(void sendAndReceive())") @Before("execution(String greeting(..)) && args(context)") but I don't know how they are called. Could you recommend some tutorials? This style is called @AspectJ to emphasize the role of annotations. Have a look at official docs and @AspectJ cheat sheet . Annotation and the XML ways: Annotation
