打印出每个接口的请求时间(ThreadLocal,SpringA

自定义MyThreadLocal和Spring Aop 切面编程在开发模式下打印出接口请求时间。

导入依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-aop</artifactId>
        </dependency>

自定义MyThreadLocal

/**
 *
 * 自定义ThreadLocal.
 */
public class MyThreadLocal<T> extends ThreadLocal<T> {

    @Override
    public T get() {
        remove();
        return super.get();
    }

    public T get2() {
        return super.get();
    }
}

SpringAop 配置

/**
 * 
 * 开发模式下打印出每个接口的请求时间（毫秒）.
 */
@Aspect
@Component
@Slf4j
@Profile({"dev", "test"})// 设置 dev test 环境开启
public class ControllerAspect {

    private static final MyThreadLocal<Long> time = new MyThreadLocal<Long>() {
        @Override
        protected Long initialValue() {
            return System.nanoTime();
        }
    };

    @Before("execution(* com.xxxxx.controller..*.*(..))")
    public void beforeLog() {
        time.get();
    }

    @After("execution(* com.xxxxx.controller..*.*(..))")
    public void afterLog(JoinPoint joinPoint) {
        log.error(joinPoint.toShortString() + " periods " + (int) ((System.nanoTime() - time.get2()) / 1000000) + "毫秒");
    }
}

到此，就可以打印出每个controller层的接口的请求时间。
