问题 What is the simplest pointcut expression that would intercept all public methods of all beans annotated with @Service ? For instance, I expect it to affect both public methods of this bean: @Service public MyServiceImpl implements MyService { public String doThis() {...} public int doThat() {...} protected int doThatHelper() {...} // not wrapped } 回答1: This documentation should be extremely helpful. I would do by creating two individual point cuts, one for all public methods, and one for all

问题 The question I have today is how to retry a method after the @Transactional annotation causes an Optimistic Lock Exception (OLE) and rolls back the transaction. I have asynchronous calls to a Restful application that are attempting to update a database object based on some business logic. If I get an OLE, I'd like to retry the transaction after a delay of 0.2-0.5 seconds. @Transactional(rollbackFor = Throwable.class, propagation = Propagation.REQUIRED, readOnly = false) public Response

问题 Goal: Start up a server which supports remote access to method calls. The application doesn't fail till after all services are created. The jar is in the target/lib directory. Parent pom has the dependency: <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${version.spring}</version> </dependency> Note: I am able to create a spring bean of type: org.springframework.aop.framework.ProxyFactory Stack Trace: 36438 [main] ERROR org.springframework.web

问题 I have a spring boot 2 java app and would like to use interpreted (not compiled) groovy code to inject aop. From reading the spring documentation this sounds like it is possible, but I could'nt find any examples. AOP - advising scripted beans: You are of course not just limited to advising scripted beans…​ you can also write aspects themselves in a supported dynamic language and use such beans to advise other Spring beans. This really would be an advanced use of the dynamic language support

问题 I read that Spring AOP cannot intercept private and protected methods but it is intercepting them in a weird way why is that? I have these functions i want to intercept: public String getName(String string) { System.out.println("Name : " + name + string); return name; } protected String getNamesprotected(String string) { System.out.println("Name : " + name + string); return name; } This is my @Aspect code: @Aspect public class Logging { @Before("execution(* com.tutorialspoint.Student.*Name*(.

问题 I have created a spring aspect to handle Retry mechanism. I have also created a Retry annotation. Following is the code for Retry annotation and an aspect which processes this annotation. @Retention(RetentionPolicy.RUNTIME) @Target(ElementType.METHOD) public @interface Retry { /** * List of exceptions for which we need to retry method invocation. * * @return Array of classes. */ Class<?>[] exceptions(); /** * Number of retries. Default is 3. * * @return Number of retires. */ int retries()

问题 getDescription method of Object of class Title was intercepted by an aspect. How do I get access to instance of object itself. @Around("execution(String com.*.*.*.Title.getDescription(..))") public String getInternationalizedTitleDescription(ProceedingJoinPoint joinPoint) throws Throwable { if (something){ return joinPoint.proceed(); } else { //here I need access to instance to Title //Title t = joinPoint.getObject(); //return SomeOtherObject.getTitleData(t); } } 回答1: Use ProceedingJoinPoint

问题 I am trying to inject behaviour to my bean through the 'Introduction' aspect - but unsuccessful so far. Any help is appreciated. The behaviour to 'introduce': public interface MinCalculator{ public double min(double a,double b); } public class MinCalculatorImpl implements MinCalculator{ public double min(double a,double b){ double result=(a<b)?a:b; return result; } } The implementation class: public class MathsImpl{ public void run(){ System.out.println(" This is me ");} public static void
