How to Autowire members reliably inside an Aspect - even after a context refresh?

由 為{幸葍}努か 提交于 2019-12-07 15:26:33
问题 I have an AspectJ aspect in which I want to have @Autowired fields. Given that by default, the aspects are singletons created outside the Spring container, Spring does not manage any of the dependency injection for the aspect. Searching around on SO, Spring autowired bean for @Aspect aspect is null encountered the same problem, and using the @Configurable annotation on the aspect somehow magically allows Spring to do the dependency injection (see @codebrickie response). I'm still not entirely

Spring AOP and Post Construct

由 别等时光非礼了梦想. 提交于 2019-12-07 14:06:49
问题 I want to write the name of method which is using with @PostConstruct. But I found that AOP is unable to "Around" the PostConstruct method. Is there any way to use AOP with PostConstruct method? 回答1: Give this a try. @Around("@annotation(javax.annotation.PostConstruct)") public void myAdvice(ProceedingJoinPoint jp) throws Throwable{ System.out.println("This is before " + jp.getSignature().getName() + "()"); jp.proceed(); } Additionally you need to activate compile-time weaving.

Spring之旅第五篇-AOP详解

一、什么是AOP？ Aspect oritention programming(面向切面编程)，AOP是一种思想，高度概括的话是“横向重复，纵向抽取”，如何理解呢？举个例子：访问页面时需要权限认证，如果每个页面都去实现方法显然是不合适的，这个时候我们就可以利用切面编程。 每个页面都去实现这个方法就是横向的重复，我们直接从中切入，封装一个与主业务无关的权限验证的公共方法，这样可以减少系统的重复代码，降低模块之间的耦合度，简单的示意图如下： 二、应用场景 AOP用来封装横切关注点，具体可以在下面的场景中使用: Authentication 权限 Caching 缓存 Context passing 内容传递 Error handling 错误处理 Lazy loading　懒加载 Debugging　　调试 l ogging, tracing, profiling and monitoring　记录跟踪　优化　校准 Performance optimization　性能优化 Persistence　　持久化 Resource pooling　资源池 Synchronization　同步 Transactions 事务 三、相关概念 1.连接点（Joinpoint） 所谓连接点是指那些可能被拦截到的方法。例如：所有可以增加的方法 2.切点（Pointcut） 已经被增强的连接点 3.增强

Spring - Injecting resources in per-scoped (perthis - pertarget) aspect

由 自古美人都是妖i 提交于 2019-12-07 10:43:32
问题 In my Spring web application, I'm trying to inject a resource in a perthis-scoped AspectJ aspect. Injection works well using a singleton aspect, but fails using a perthis scoped one. I tried using both @Autowire annotation or xml <property> tag. Here is my code. Aspect (for @Configurable I tried both autowire=Autowire.BY_TYPE and autowire=Autowire.BY_NAME ): @Aspect( "perthis(org.mypackage.aop.aspects.TestAspect.participateAroundPointcut())") @Component @Scope("prototype") @Configurable()

Spring-AOP load-time weaving on 3rd-party classes

由 倾然丶 夕夏残阳落幕 提交于 2019-12-07 06:08:37
I wrote an aspect that I'm trying to test with junit. The aspect has an @Around advice on a 3rd party method called setQuery . At compile time it complains: Can't find referenced pointcut setQuery Here's my aspect: @Component @Aspect public class ElasticsearchQuerySecurityAspect { @Around("org.elasticsearch.action.search.SearchRequestBuilder.setQuery() && args(queryBuilder)") public void addFilter(final ProceedingJoinPoint pjp, QueryBuilder queryBuilder) throws Throwable { Object[] args = pjp.getArgs(); // Set the filter to use our plugin FilterBuilder securityFilter = FilterBuilders

AspectJ - Weaving with custom ClassLoader at runtime

由 纵然是瞬间 提交于 2019-12-07 05:28:36
问题 I'm trying to load classes at runtime and weave them with some AspectJ aspects at this point. I have load-time weaving enabled, and it works when I use it more conventionally. I have the following in my @Aspect class: @Before("call(* mypackage.MyInterface.*())") public void myInterfaceExecuteCall(JoinPoint thisJoinPoint, JoinPoint.StaticPart thisJoinPointStaticPart, JoinPoint.EnclosingStaticPart thisEnclosingJoinPointStaticPart) { System.out.println(thisJoinPoint.getSignature()

Maven, Scala, Spring, AspectJ

由 流过昼夜 提交于 2019-12-07 05:24:11
问题 Does anyone know if you can weave scala classes at compile time with aspectJ & spring. I have compile time weaving working for all my java classes but I can't seem to get it to work for my scala classes that use @Configurable. 回答1: For background I have been working on this for a couple of days. What a pain. Anyways here's the answer. Yes it can be done, you just can't use the aspectj maven plugin. You have to use the antrun maven plugin. Happy Scala Coding! <plugin> <groupId>org.apache.maven

AspectJ matching return type as interface with generics

问题 I'm trying to create an AspectJ Aspect to intercept the returning methods that has a generic interface.
