带有@Loggable批注的方法从不打印方面日志 [英] Method with @Loggable annotation never prints aspect log

问题描述

我想实现记录使用某些注释注释的某些方法的进入和退出的功能(例如:@Loggable).我遇到了AspectJ AOP，我们可以使用它进行操作.

I want to implement the ability to log entry and exit of some methods that are annotated with some annotation (For example: @Loggable). I came across AspectJ AOP using which we can do this.

我实现了自己的自定义方面，以自定义要在使用@Loggable调用的方法的进入和退出时打印的日志消息:

I implemented a custom aspect of my own to customise the log message I want to print on entry and exit of the method that gets called with @Loggable:

@Aspect
public final class MethodLogger {

  private static final Logger LOG = LoggerFactory.getLogger(MethodLogger.class);

  @Around("execution(* *(..)) && @annotation(Loggable)")
  public Object around(ProceedingJoinPoint point) throws Throwable {

    String className = MethodSignature.class.cast(point.getSignature()).getClass().getName();
    String methodName = MethodSignature.class.cast(point.getSignature()).getMethod().getName();
    LOG.info(
        "Entering method:{}() of class:{} with parameters: {}",
        methodName,
        className,
        Arrays.toString(point.getArgs()));

    try
    {
      return point.proceed();
    }
    catch(Throwable e){
       throw e;
    }
    finally
    {
      LOG.info(
          "Exiting method:{}() of class:{} with parameters: {}",
          methodName,
          className,
          Arrays.toString(point.getArgs()));
    }

  }
}

pom.xml依赖项:

pom.xml dependencies:

<dependency>
      <groupId>com.jcabi</groupId>
      <artifactId>jcabi-aspects</artifactId>
      <version>0.22.5</version>
    </dependency>
    <dependency>
      <groupId>org.aspectj</groupId>
      <artifactId>aspectjrt</artifactId>
      <version>1.9.1</version>
    </dependency>

类的方法带有@Loggable注释:

@Component
public class LoginPage extends BasePage {

@Loggable
public Object login(String username, String password) {

}

}

问题:

主要通过以下方式调用此实例方法(login())时: loginPage.login()，我看不到进入和退出日志正在打印到日志输出中.

When this instance method (login())is called mostly in the following manner: loginPage.login(), I cannot see the entry and exit log being printed to the log output.

请注意:

• 我正在使用Spring依赖注入使用@Component批注初始化此类，但不确定这是否对论坛有用，但仍然让大家知道.
• 这是一个测试自动化项目，我从JUnit + Cucumber运行器类中触发了一些UI自动化测试.
• 我没有从Maven触发测试.

• I am using Spring dependency injection to initialise such classes with @Component annotation, not sure if that is useful information for the forum but still letting you all know.
• This is a test automation project where I am triggering some UI automated tests from a JUnit+Cucumber runner class.
• I am not triggering my tests from maven.

有人可以建议这里出什么问题吗?

Can someone suggest what could be going wrong here?

推荐答案

您的方面MethodLogger尚未初始化.尝试将@Component添加到MethodLogger.这应该将方面加载并注册到上下文中，以使其可以使用.

You aspect MethodLogger is not initialized yet.Try adding @Component to the MethodLogger. This should load and register the aspect into the context, making it ready for use.

此外，您可能想简化切点@Around("execution(* *(..)) && @annotation(Loggable)").

Also you might want to simplify your point cut @Around("execution(* *(..)) && @annotation(Loggable)").

execution(* *(..))基本上是通配符，因此没有用.只需使用@Around("@annotation(Loggable)").

execution(* *(..)) is basically a wild card and therefore useless. Just use@Around("@annotation(Loggable)").
