SpringAOP PerformanceMonitorInterceptor Sınıfı

Giriş

Şu satırı dahil ederiz

import org.springframework.aop.interceptor.PerformanceMonitorInterceptor;

Açıklaması şöyle

When you enable the “PerformanceMonitorInterceptor,” it quietly observes your code and collects essential information, such as the execution time of different methods. It keeps a record of how much time is spent in each method, which is incredibly helpful in identifying bottlenecks or areas where your code might be slowing down.

Having access to this information allows you to analyze and optimize your code to make it faster and more efficient. For example, if you discover that a particular method is taking too much time to execute, you can focus on optimizing that specific part of your code to improve overall performance.

Moreover, the “PerformanceMonitorInterceptor” enables you to measure the performance of your code across multiple requests or interactions. This broader perspective helps you understand how your application is performing over time, rather than relying on isolated measurements.

AbstractMonitoringInterceptor sınıfından kalıtır. Loglama ayarları için şöyle yaparız

logging.level.dev.knowledgecafe=TRACE
logging.level.org.springframework.aop.interceptor.PerformanceMonitorInterceptor=TRACE

Örnek

Şöyle yaparız

@Configuration
@EnableAspectJAutoProxy
public class AopConfiguration {
  @Pointcut("execution(public String foo.EmployeeService.getFullName(..)))")
  public void monitor() { }

  @Bean
  public PerformanceMonitorInterceptor performanceMonitorInterceptor() {
    return new PerformanceMonitorInterceptor(true);
  }

  @Bean
  public Advisor performanceMonitorAdvisor() {
    AspectJExpressionPointcut pointcut = new AspectJExpressionPointcut();
    pointcut.setExpression("dev.knowledgecafe.performance_trace.AopConfiguration.monitor()");
    return new DefaultPointcutAdvisor(pointcut, performanceMonitorInterceptor());
  }
}
