自定义注解、切面，监控每个controller执行时长

ExecuteTime注解

@Target(ElementType.METHOD)//注解用在方法上，用于描述方法
@Retention(RetentionPolicy.RUNTIME)//注解在运行时保留
@Documented//指定javadoc生成API文档时显示该注解信息
public @interface ExecuteTime {
    //调用时长阈值，默认为0，单位为毫秒，运行时长超过threshold毫秒时打印运行时长日志
    int threshold() default 0;

    String msg() default "";

    String postfix() default "接口---执行时长:{}毫秒";

    //日志级别
    LogLevel logLevel() default LogLevel.info;
}

InvokeTimeAdvice

@Aspect
public class InvokeTimeAdvice {

    @Pointcut("execution(public * com.htjc..*.*(..))&&@annotation(executeTime)")
    public void pointCut(ExecuteTime executeTime) {
    }

    ;

    @Around("pointCut(executeTime)")
    public Object logInvokeTime(ProceedingJoinPoint joinPoint, ExecuteTime executeTime) throws Throwable {
        long start = System.currentTimeMillis();//开始时间
        final Logger LOGGER = LoggerFactory.getLogger(joinPoint.getTarget().getClass());
        try {
            return joinPoint.proceed();
        } finally {
            long end = System.currentTimeMillis();//结束时间
            long duration = end - start;
            if (duration >= executeTime.threshold()) {
                String msg = executeTime.msg();
                if (msg == null || msg.trim().length() == 0) {
                    String methodName = joinPoint.getSignature().getName();//方法名
                    LogUtils.log(LOGGER, executeTime.logLevel(), "方法[{}]执行时长:{}毫秒", methodName, duration);
                }
            } else {
                LogUtils.log(LOGGER, executeTime.logLevel(), executeTime.msg() + executeTime.postfix(), duration);
            }
        }
    }
}

advice bean注入applicationContext.xml

<!--切面 start-->
    <!--记录方法执行时长-->

    <!--切面 end-->
