我们可以计算Spring bean初始化时间吗

import org.springframework.aop.MethodBeforeAdvice;
import java.lang.reflect.Method;

public class BeanInitializationTimeAdvice implements MethodBeforeAdvice {
    private long startTime;

    @Override
    public void before(Method method, Object[] args, Object target) throws Throwable {
        startTime = System.currentTimeMillis();
    }

    public long getInitializationTime() {
        return System.currentTimeMillis() - startTime;
    }
}

<bean id="beanInitializationTimeAdvice" class="com.example.BeanInitializationTimeAdvice" />

<aop:config>
    <aop:aspect ref="beanInitializationTimeAdvice">
        <aop:before pointcut="execution(* com.example.MyBean.*(..))" method="before" />
    </aop:aspect>
</aop:config>

BeanInitializationTimeAdvice advice = (BeanInitializationTimeAdvice) applicationContext.getBean("beanInitializationTimeAdvice");
long initializationTime = advice.getInitializationTime();
System.out.println("Bean initialization time: " + initializationTime + "ms");
