在 SpringBoot rest 中记录执行时间 API

Question

这可能是一个简单的解决方案，但我无法完成。我需要在 SpringBoot Rest API 中记录我的请求的整体执行时间。请求总是进入到MainController总是并且可以从两个地方退出-

主要Restcontroller相同方法或
ExceptionHandlerController处理方法

我创建了一个自定义注释并将其注入主要 Controller 和 ExceptionController 方法，并获取各个方法的运行时间。所以这就是问题所在。我需要添加这些单独的时间来计算我不想要的总时间。

有没有其他方法可以轻松记录此信息。

看点class:

@Aspect
@Component
public class PointsAspect {

    private final static Logger logger = LoggerFactory.getLogger(PointsAspect.class);

    @Around("@annotation(annotation)")
    public Object logMethod(final ProceedingJoinPoint proceedingJoinPoint, final LogAround annotation)
            throws Throwable {
        final long start = System.currentTimeMillis();
        Object obj;
        try {
            logger.debug("Starting...! Method Name - " +proceedingJoinPoint.getSignature().getName());
            obj = proceedingJoinPoint.proceed();
        } finally {
            logger.debug("Exiting...! Method Name - " +proceedingJoinPoint.getSignature().getName() +"Execution Time in Milliseconds:> "+ String.valueOf(System.currentTimeMillis()-start));
        }
        return obj;
    }
}

标记接口：

@Target({ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
public @interface LogAround {

}

我是这样注射的：

**ExceptionHandlerController.java**

@LogAround
@ExceptionHandler(HttpMessageNotReadableException.class)
public GenericFailureResponse missingRequestBodyException(HttpServletResponse response,
            HttpServletRequest request, Exception ex) throws IOException {
        GenericFailureResponse failureResponse =  new GenericFailureResponse();
        //TODO: exception logic
        return failureResponse;
}



**MainController.java**

@LogAround
 public String getTotalPoints(@RequestParam(required=true) long memberNo,
            HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) {
        //TODO : some logic
        return "something";
 }

Answer 1

您可以使用简单的过滤器。

@Component
public class LogTimeFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
        long startTime = System.currentTimeMillis();
        chain.doFilter(request, response);
        long duration = System.currentTimeMillis() - startTime;
        System.out.println("Request take " + duration + " ms");
    }
}
