java-annotations

问题 I'm trying to get a Class object reference for the annotation which caused a ConstraintViolation in the javax.validation package (Apache Bval implementation). After getting some ConstraintViolations, I pass them into the following function: private Class<?> getConstraintAnnotation(final ConstraintViolation<?> constraintViolation) { return constraintViolation .getConstraintDescriptor() .getAnnotation() .getClass(); } And this returns a class object whose getName() , getCanonicalName() , and

问题 It could be a simple solution but I am unable to get it done. I need to log the overall execution time for my request in SpringBoot Rest API. Request always enters to MainController always and can exit from two places- Main Restcontroller same method or ExceptionHandlerController handler method I have created one custom annotation and injecting it to both main Controller and ExceptionController methods and getting elapsed time for individual methods. So here is the problem. I need to add

问题 I have written the following annotation: import java.lang.annotation.ElementType; import java.lang.annotation.Retention; import java.lang.annotation.RetentionPolicy; import java.lang.annotation.Target; @Retention(RetentionPolicy.SOURCE) @Target({ElementType.METHOD}) public @interface Warning { } Which is intended to annotate methods which can cause problems if called carelessly. I added an annotation processor to my project, but this only provides the warning in the log output of the javac

问题 I am trying to write a scanner for custom annotations based on the answer in Scanning Java annotations at runtime. However, to speed up the process, I only want to scan the classes under the main package (package which has the main class and its sub-packages). Figured that the easiest way to determine the package name would be from the main class. The code I am writing would end up in a library which will be used by Spring Boot applications. So I have no way of knowing the name of the main
