1.创建annotation,代码如下
@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface InterfaceProperty {

/**
 * 接口超时时间,单位毫秒.默认值400毫秒
 *
 * @return 设置的超时时间
 */
int timeout() default 400;

}

2.创建切面

@Component
@Aspect
public class SystemRequestAspect {

private static final Logger LOG = LoggerFactory.getLogger(SystemRequestAspect.class);
@Around(value = "execution(* com.csot.mass.background.controller..*.*(..))", argNames = "pjp")
public Object validator(ProceedingJoinPoint pjp) throws Throwable {
    Object[] args = pjp.getArgs();
    Signature sig = pjp.getSignature();
    MethodSignature msig = null;
    if (!(sig instanceof MethodSignature)) {
        throw new IllegalArgumentException("该注解只能用于方法");
    }
    msig = (MethodSignature) sig;
    Object target = pjp.getTarget();
    Method currentMethod = target.getClass().getMethod(msig.getName(), msig.getParameterTypes());
    String className = target.getClass().getName();
    String methodName = currentMethod.getName();
    /** 拦截的方法名称 */
    try {
        long start = System.currentTimeMillis();
        Object obj = pjp.proceed(args);
        long finish = System.currentTimeMillis();
        long useTime = finish - start;
        if (currentMethod.isAnnotationPresent(InterfaceProperty.class)) {
            InterfaceProperty interfaceProperty = currentMethod.getAnnotation(InterfaceProperty.class);
            if (useTime >= interfaceProperty.timeout()) {
                LOG.info("接口超时",
                        className + "." + methodName,
                        useTime);
            }
        }
        return obj;
    } catch (Exception e) {
        LOG.error(e.getMessage());
    }
    return null;
}

}
