我有一个有效的AOP(在项目内部使用时被写入),但是当我构建该项目(maven安装),并在另一个项目中使用该JAR,并尝试使用@TimedLog
批注时,什么都没发生。我试图在其中断点,但是它没有到达那里。
它看起来像这样:
@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.METHOD)
public @interface TimedLog {
boolean shouldAttachMethodArgs() default false;
boolean shouldAttachReturnValue() default false;
String message() default "";
}
这是实际的方面:
@Aspect
@Configuration
@Slf4j
public class MethodExecutionAspect {
@Pointcut("@annotation(timedLogVar)")
public void annotationPointCutDefinition(TimedLog timedLogVar) {}
@Pointcut("execution(* *(..))")
public void atExecution() {}
@Around(value = "annotationPointCutDefinition(timedLogVar) && atExecution()", argNames = "joinPoint,timedLogVar")
public Object around(ProceedingJoinPoint joinPoint, TimedLog timedLogVar) throws Throwable {
Stopwatch stopwatch = Stopwatch.createStarted();
Object returnValue = joinPoint.proceed();
stopwatch.stop();
log.info(String.format("test message %s", stopwatch.elapsed(TimeUnit.MILLISECONDS)));
return returnValue;
}
}
它的实现是:
@TimedLog
void testDefaultValues() throws InterruptedException {
int sleepTimeInMillis = 200;
log.info("Resting for {} millis", value("sleepTimeInMillis", sleepTimeInMillis));
Thread.sleep(sleepTimeInMillis);
}

从这里您可以看到,这是一个装饰方法并记录其运行时的AOP。
我已经为此苦苦挣扎了一段时间,非常感谢您的帮助。
谢谢

根据要求,使用该AOP的项目的完整pom.xml(位于foo.bar.utils

EDIT2: 无效的实现(在应该使用AOP的其他项目中)
@Slf4j
@Configuration
@EnableAspectJAutoProxy
public class TestingSomething {
@TimedLog(message = "test something")
public void testingSomething() {
log.info("ololol");
}
}
然后是测试,对其进行测试:
@RunWith(SpringRunner.class)
@SpringBootTest(classes = SomeSpringConfiguration.class,
properties = {"server.port=0", "enable.security=true"})
@WebAppConfiguration
public class testingSomethingTest {
@Autowired
TestingSomething testingSomething;
@Test
public void testingLol() {
testingSomething.testingSomething();
}
}
答案 0 :(得分:3)
要使各方面正常工作,您需要启用它们。要启用它,您需要通过xml或通过注释配置它们:
@Configuration
@EnableAspectJAutoProxy
通过xml:
<beans …>
<!– Enable AspectJ auto-wiring –>
<aop:aspectj-autoproxy />
</beans>
将jar包含在另一个应用程序中时,该另一个应用程序具有自己的配置和上下文。即使您为原始上下文启用了方面自动装配,您仍然需要通过上述两种方式之一对新应用程序执行相同的操作。
如果您使用注释,请确保它在组件扫描范围之内并且确实包含在您的上下文中。
更新:
对您的testingSomethingTest做@Import (MethodExecutionAspect.class)
,以确保对其进行了组件扫描。
