I want to do some action when this method has an exception. Therefore I made aop function like AfterReturning, AfterThrowing...
I changed the method raising exception on purpose. But the request arrives AfterReturning, not AfterThrowing even if exception is occured.
How can I make this request reach to AfterThrowing method?
@EventListener
@GetHost
public void getHost(ContextRefreshedEvent event) throws Exception {
try {
prHostName = InetAddress.getLocalHost().getHostName();
prIpAddr = InetAddress.getLocalHost().getHostAddress();
//making exception on purpose
String[] tmp = new String[0];
prIpAddr = tmp[1];
} catch (Exception exception) {
prHostName = "unknown";
prIpAddr = "unknown";
System.out.println("unknown");
exception.printStackTrace();
}
}
There are aop methods
@Pointcut("@annotation(com.etc.web.annotation.GetHost)")
public void componentMethod() {}
@Before("componentMethod()")
public void beforeComponent(JoinPoint point) {
System.out.println("beforeComponent");
}
@Around("componentMethod()")
public Object aroundComponent(ProceedingJoinPoint point) throws Throwable {
System.out.println("aroundComponent");
Object retVal = point.proceed();
return retVal;
}
@AfterReturning(pointcut = "componentMethod()", returning = "result")
public void afterComponent(JoinPoint point, Object result) {
System.out.println("afterReturnComponent");
}
@AfterThrowing(pointcut = "componentMethod()", throwing = "exception")
public void afterThrowingComponent(JoinPoint point, Throwable exception) throws Exception {
System.out.println("afterThrowingComponent");
}
Please help me. Thanks!
The method does not exit with an exception, because the exception is caught and the method exits normally. So of course, @AfterThrowing is not triggered. That should not surprise you.
