Everything works fine so far within IntelliJ, I can compile, run my Unit-Tests, deploy and run my web-application to/on Wildfly and so on. When building my project in IntelliJ, I can see usage of the required aspects (the following warning is ok). org.springframework.data.neo4j.aspects.support.node.Neo4jNodeBacking

问题 I am working with Spring Framework 4.3.3 in a web environment. I have a @Controller used for Web requests through a Web Browser that uses how dependency other @Controller but for Rest purposes. It latter mentioned uses a @Service etc... This approach about a 'Web' using a 'Rest' how a dependency is explained in Content Negotiation using Spring MVC for the Combining Data and Presentation Formats section. Until here for development/testing and production works fine. It is a valuable approach.

Note it applies for @Configuration classes too. (Infrastructure) Therefore with the

Get all exceptions in Java and send them remotely

阅读更多关于 Get all exceptions in Java and send them remotely

I have a huge Java application. I want to intercept all Java Exceptions adn send them by e-mail. I can't add everywhere code for sending the code via try-catch so is it possible to use for example Aspect to intercept the exception into low level classes and get the exception content? Or is there some way to override some internal Java Class and get the exception payload? What is possible? You can use the @AfterThrowing advice of spring-aop . @Aspect @Component public class MailExceptionAspect { @AfterThrowing(value="execution(* com.example..*.*(..))", throwing="ex" ) public void

To exclude certain methods I created a custom annotation which I use to filter out. However I'm unable to do the same with classes. Here is my aspect definition - @Around("execution(* com.foo.bar.web.controller.*.*(..)) " + "&& !@annotation(com.foo.bar.util.NoLogging)") public Object log(ProceedingJoinPoint
