When apply the handy Assert.notNull, we should be aware that it might throw IllegalArgumentException.

@Aspect@Componentpublic class ExceptionAspect {private final Logger log = LoggerFactory.getLogger(getClass());@AfterThrowing(throwing = "ex", pointcut = "within(com.xxx.broker..*)")public void catchIllegalArgumentException(Throwable ex) {log.error("IllegalArgumentException occurs! ", ex);}}

Test:

@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = "classpath*:applicationContext.xml")@ActiveProfiles("test")public class ExceptionAspectTest {@Autowiredprivate IBrokerService brokerService;@Testpublic void testInputNull(){brokerService.getAllHoldings(null);}}

Service

@Overridepublic Response getAllHoldings(Request request) {Assert.notNull(request);Response response = new Response();...return response;}

Application context:

<aop:aspectj-autoproxy />
