08、点评CAT之AOP监控method

SpringBoot AOP注解方式监控方法执行时间
源码中提供了CatAnnotation 以及 CatAopService 这两个类可以参照这两个类

1、在pom.xml中引入AOP的支持

<!-- SpringBoot对AOP的支持 -->
<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-aop</artifactId>
</dependency>

2、书写CatAnnotation注解类

@Retention(RUNTIME)
@Target(ElementType.METHOD)
public @interface CatAnnotation {
}

3、书写CatAopService AOP类

@Aspect
@Component
public class CatAopService {

    @Around("@annotation(catAnnotation)")
    public Object aroundMethod(ProceedingJoinPoint pjp, CatAnnotation catAnnotation) {
        MethodSignature joinPointObject = (MethodSignature) pjp.getSignature();
        Method method = joinPointObject.getMethod();
        Transaction t = Cat.newTransaction("method", method.getName());
        try {
            Object result = pjp.proceed();
            t.setStatus(Message.SUCCESS);
            return result;
        } catch (Throwable e) {
            t.setStatus(e);
            Cat.logError(e);
        } finally {
            t.complete();
        }
        return null;
    }
}

4、在相应的方法上面加上@CatAnotation注解

5、观察CAT监控页面
