作为AspectJ和Spring AOP的新手,我有一个其中定义了Aspects的Spring AOP项目。切入点在注释Loggable
上定义。每当执行带有@Loggable
的方法时,建议都应执行。
注释:
@Target(ElementType.METHOD)
@Retention(RUNTIME)
public @interface Loggable {
String customMessage() default "";
String[] properties() default {};
String type();
}
下面是Aspect类:
LoggingAspect:
@Aspect
@Component
public class LoggingAspect {
private final Logger LOGGER = Logger.getLogger(this.getClass());
@Around("loggablePointcut(loggableAnnotation)")
public Object beforeDebug(ProceedingJoinPoint joinpoint, Loggable loggableAnnotation) throws Throwable {
final String logType = loggableAnnotation.type();
LOGGER.log(Level.toLevel(logType), joinpoint.getSignature().toString() + " - " + loggableAnnotation.customMessage());
System.out.println("in here");
// Default Object that we can use to return to the consumer
Object returnObject = null;
try {
returnObject = joinpoint.proceed();
} catch (Throwable throwable) {
throw throwable;
}
return returnObject;
}
@Pointcut("@annotation(loggableAnnotation)")
public void loggablePointcut(Loggable loggableAnnotation) {
}
}
现在使应用程序可运行并在本地进行一次测试:
Application.java:
@SpringBootApplication
public class Application {
@Loggable(type = "info")
public void testing() throws NoSuchMethodException, SecurityException {
System.out.println("testing");
}
public static void main(String[] args) throws NoSuchMethodException, SecurityException {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
Application app = (Application) ctx.getBean("application");
app.testing();
System.err.println("Executed from project A");
}
}
直到这里一切都正常。现在,我的实际要求是在我的其他Spring Boot项目中使用这些方面。我读过this article here,但似乎听不懂。
我对以下问题感到困惑:
Q1。如何将AspectJ项目导出为其他项目中的jar?我右键单击并将其导出为jar,然后导入生成的jar,一切正常吗? (我尝试过,但是没用)
Q2。我可以在这里使用其他任何选项吗?
