注入的实例变量在方面执行时为null
|
我在Spring AOP中遇到这个奇怪的问题，我希望有人能对此有所了解。
我正在使用CGLIB代理，执行以下方面时，我得到一个空指针：
@Aspect
@Component //i.e. Singleton
public class MyAspect {
private static final Logger logger = LoggerFactory.getLogger(MyAspect.class);
{
logger.debug(\"new instance of MyAspect\"); //Line 1
}
private AutowireCapableBeanFactory factory;
@Inject
public MyAspect(AutowireCapableBeanFactory factory) {
if (factory ==null) {
logger.debug(\"your factory is null\"); //Line 2
} else {
logger.debug(\"your factory is not null\");
}
this.factory = factory;
}
@AfterReturning(pointcut = \"@annotation(com.domain.annotations.MyAnnotation)\")
public void doSomething() {
if (factory ==null) {
logger.debug(\"your factory is null again\"); //Line 3
}
// this is a request scoped bean
MyRequest request = factory.getBean(MyRequest.class); //Line 4
if (request != null) {
logger.debug(\"No\");
}
else {
logger.debug(\"Yes\");
}
}
}
没有找到相关结果

@Aspect @Component(\"auditAspect\") public class AuditAspect implements ApplicationContextAware { ApplicationContext context; public Object doAround(ProceedingJoinPoint pjp) throws Throwable { // do stuff with context here } public void setApplicationContext(ApplicationContext applicationContext) throws BeansException { this.context = applicationContext; }
