如果没有Maven重建，无法在IntelliJ IDEA中运行AspectJ CTW应用程序

Question

编辑/更新:委托IDE构建/运行操作maven在IntelliJ设置解决问题，但如何处理它没有它?

我有以下问题:

我在我的GetSthAspect类中改变了一些东西->然后我运行maven clean install(让我们假设我必须总是在我的应用程序中做clean install) ->运行spring app ->我看到错误:

java.lang.NoSuchMethodError: com.example.demo.aspects.GetSthAspect.aspectOf()Lcom/example/demo/aspects/GetSthAspect;
at com.example.demo.aspects.A.shouldDoSthAndCallMethodGetSth(A.java:15) ~[classes/:na]

at org.springframework.web.method.support.InvocableHandlerMethod.invokeForRequest(InvocableHandlerMethod.java:150) ~[spring-web-5.3.10.jar:5.3.10]
...

然后我停止app ->再次执行maven clean install ->再次运行应用程序，现在一切正常。

当我在我的GetSthAspect类中改变了一些东西，我想在app中看到我的改变时，总是这样。为什么呢?为什么我必须创建app ->运行app ->停止应用程序->再次构建应用程序，并运行它，以我的方面工作良好吗?我该怎么做才能避免这种情况呢?

GetSthAspect

@Aspect
public class GetSthAspect {
Logger logger = LoggerFactory.getLogger(GetSthAspect.class);
@Around("call(* Ent.getSth())")
public Object around(ProceedingJoinPoint  pjp) throws Throwable {
logger.info("Inside around + 12:52");
Ent ent = (Ent) pjp.getTarget();
logger.info("Number: " + ent.getImportantNumber());
return pjp.proceed();
}
}

一些类

public class AspectApp {
Logger logger = LoggerFactory.getLogger(AspectApp.class);
@GetMapping("/")
public String main() {
logger.info("Method main started + 11:01");
A a = new A();
a.shouldDoSthAndCallMethodGetSth(1);
}
}

public class A {
Logger logger = LoggerFactory.getLogger(A.class);
public void shouldDoSthAndCallMethodGetSth(Integer a) {
// ...
Ent ent = new Ent();
ent.setImportantNumber(1);
logger.info("Method A do sth and ...");
ent.getSth();
}
}

我不知道问题在哪里。通常情况下，您不需要在每次更改代码时都保持maven clean install。我建议你使用devtools也许
