方面不适用于带有外部jar的Spring Boot应用程序

Question

@Retention(RetentionPolicy.RUNTIME)
@Target(value = {ElementType.METHOD, ElementType.TYPE})
public @interface Timer {
    String value();
}

@Aspect
public class MetricAspect {

    @Autowired
    private MetricsFactory metricsFactory;

    @Pointcut("@annotation(my.package.Timer)")
    public void timerPointcut() {}

    @Around("timerPointcut() ")
    public Object measure(ProceedingJoinPoint joinPoint) throws Throwable {
       /* Aspect logic here */
    }

    private Timer getClassAnnotation(MethodSignature methodSignature) {
        Timer annotation;
        Class<?> clazz = methodSignature.getDeclaringType();
        annotation = clazz.getAnnotation(Timer.class);
        return annotation;
    }

我有一个配置类，如下所示：

@Configuration
@EnableAspectJAutoProxy
public class MetricsConfiguration {

    @Bean
    public MetricAspect notifyAspect() {
        return new MetricAspect();
    }
}

在这里之前的所有内容都定义在一个打包的jar中，我在spring boot应用程序中使用它作为依赖项

在Spring Boot应用程序中，我导入了MetricsConfiguration，并调试了代码，看到创建了MetricAspectbean。

@Service
public class MyService {
    ...

    @Timer("mymetric")
    public void foo() {
       // Some code here...
    }

    ...
}

<dependencies>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>1.7.4</version>
    </dependency>

    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>1.7.4</version>
    </dependency>
</dependencies>

这是@configuration类，用于导入MetricsConfiguration:

@Configuration
@EnableAspectJAutoProxy
@Import(MetricsConfiguration.class)
@PropertySource("classpath:application.properties")
public class ApplicationConfiguration {

}

它加载了Spring的自动配置加载。

Answer 1

@component或@configurable能解决您的问题吗？

@Aspect
@Component
public class yourAspect {
 ...
}

启用Spring AOP或AspectJ
