    private final Logger logger = LoggerFactory.getLogger(this.getClass().getCanonicalName());

    @Around("requestHandlerMethod()")
    public void logResponseTime(ProceedingJoinPoint point) {
        long startTime = System.currentTimeMillis();
        try {
            point.proceed();
        }

@Configuration

}

例外：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [com.jms.JMSMessageListener] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

如果我通过从ApplicationConfig中注释掉@EnableAspectJAutoProxy来禁用方面,则它不会引发任何异常,但不会执行AspectJ建议(如预期的那样).

在我看来,通过启用aspectJ,Spring意识到该建议适用于JMSMessageListener,因此它围绕它创建了一个代理,这就是为什么Spring无法自动装配JMSMessageListener bean的原因,因为现在该bean不存在,但是该bean上的代理已经存在那里.

解决方法:

正如@Evgeni正确指出的那样,它通过更改

@EnableAspectJAutoProxy

至

@EnableAspectJAutoProxy(proxyTargetClass=true)

启用基于CGLIB的代理(默认情况下启用基于DynamicJDK的代理)

目标类也必须具有默认构造函数.这是基于CGLIB的代理工作的要求.
