aspect

I've looked through A LOT of Q&A here on the topic but can't find a definitive answer if one exists. I have a div of dynamic width and height and want to fit any sized image inside of it and keep the aspect ratio. This could be scaling the image up or down: I've tried every combo of width, height, max-width, max-height, Object-fit etc I can think of with no luck, there's always at least one case that fails. Most solutions I've seen involve some hard coded max-width or height values. Is it possible to get ALL above cases working only with CSS and a dynamically sized div container? PS my target

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

I am using aspectc++ to generate control flow of the program. trace.ah : #ifndef __trace_ah__ #define __trace_ah__ #include <cstdio> // Control flow tracing example aspect trace { // print the function name before execution starts pointcut virtual methods() = "% ...::%(...)"; advice execution (methods()) : before () { cout << "entering: " << JoinPoint::signature() << endl; // print input parameters** } advice execution(methods()) : after() { // print output parameters** cout << "leaving: " << JoinPoint::signature() << endl; } //prints return values of non void functions advice execution("% ...

I am trying to run AspectJ on Weblogic with LTW. My pointcut is for public constructor and methods, and advices are for Before, AfterReturning and AfterThrowing. I am getting following error when I access a simple "Hello World" jsp: javax.servlet.ServletException: Servlet class: 'jsp_servlet.__index' doesn't have a default constructor at weblogic.servlet.internal.StubSecurityHelper$ServletInitAction.run(StubSecurityHelper.java:315) at weblogic.servlet.internal.StubSecurityHelper$ServletInitAction.run(StubSecurityHelper.java:288) at weblogic.security.acl.internal.AuthenticatedSubject.doAs

Please see the updates below. I have a Spring Boot application where I accept TCP/IP connections: public MyClass implements InitializingBean { @Override public void afterPropertiesSet() throws Exception { try (ServerSocket serverSocket = new ServerSocket(port)) { while (true) { Socket socket = serverSocket.accept(); new ServerThread(socket).start(); } } } ... private class ServerThread extends Thread { @Override public void run() { try (InputStream input = socket.getInputStream(); OutputStream output = socket.getOutputStream()) { // Read line from input and call a method from service: service

C# 7 introduced local functions (which is great!). Suppose I have the following code: using System; using PostSharp.Aspects; namespace AspectCS7 { class Program { private static void Main() { [MyAspect] void LocalFunction() { Console.WriteLine("Hello Aspect!"); } LocalFunction(); } } [Serializable] public class MyAspect : OnMethodBoundaryAspect { public override void OnEntry(MethodExecutionArgs args) { Console.WriteLine("Entering Aspect"); } } } This code shows compile-time errors. Is it possible to apply attributes to local functions? Jon S Attributes were allowed on local functions at one

I'm having problems getting my logging aspect to log information when methods from classes of a particular package are accessed. In other words, "no" logging occurs. I even got desperate and added System.out.println statements, with no luck. All of my classes are located under the org.my.package package, i.e. org.my.package.controller , org.my.package.model , etc. Here is my Application class: package org.my.package; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.context.annotation

I created an AspectJ aspect which runs fine within a spring application. Now I want to add caching, using springs Cacheable annotation. To check that @Cacheable gets picked up, I'm using the name of a non-existing cache manager. The regular run-time behavior is that an exception is thrown. But in this case, no exception is being thrown, which suggests that the @Cacheable annotation isn't being applied to the intercepting object. /* { package, some more imports... } */ import org.aspectj.lang.ProceedingJoinPoint; import org.aspectj.lang.annotation.Around; import org.aspectj.lang.annotation
