Question

我正在使用 Spring Boot 编写Web Rest Web服务。

我想记录我的webservice处理请求所花费的时间。另外我想记录标题，方法和URI。

几个月前，我使用ContainerRequestFilter and ContainerResponseFilter filter() method.

在我的球衣网络服务中做了类似的工作

另外，AOP更好还是过滤？

Answer 1

您是否尝试使用此类基本过滤器？

import java.io.IOException;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import javax.servlet.http.HttpServletRequest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;

@Component
@WebFilter("/*")
public class StatsFilter implements Filter {

    private static final Logger LOGGER = LoggerFactory.getLogger(StatsFilter.class);

    @Override
    public void init(FilterConfig filterConfig) throws ServletException {
        // empty
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws IOException, ServletException {
        long time = System.currentTimeMillis();
        try {
            chain.doFilter(req, resp);
        } finally {
            time = System.currentTimeMillis() - time;
            LOGGER.trace("{}: {} ms ", ((HttpServletRequest) req).getRequestURI(),  time);
        }
    }

    @Override
    public void destroy() {
        // empty
    }
}

Spring boot：日志拦截器

    public class ApiLogger extends HandlerInterceptorAdapter {
        private static final Logger logger = LoggerFactory
                .getLogger(ApiLogger.class);

        @Override
        public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
            String requestId = UUID.randomUUID().toString();
            log(request,response, requestId);
            long startTime = System.currentTimeMillis();
            request.setAttribute("startTime", startTime);
            request.setAttribute("requestId", requestId);
            return true;
        }

         @Override
        public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) throws Exception {
            super.afterCompletion(request, response, handler, ex);
            long startTime = (Long)request.getAttribute("startTime");

            long endTime = System.currentTimeMillis();

            long executeTime = endTime - startTime;
            logger.info("requestId {}, Handle :{} , request take time: {}",request.getAttribute("requestId"), handler, executeTime);
        }
    private void log(HttpServletRequest request, HttpServletResponse response, String requestId) {
        logger.info("requestId {}, host {}  HttpMethod: {}, URI : {}",requestId, request.getHeader("host"),
                request.getMethod(), request.getRequestURI() );
    }
}

注册拦截器：

@Configuration
@EnableWebMvc
public class AppConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new ApiLogger()).addPathPatterns("/api/v1/*");
    }
}

David的回答是正确的 - 过滤器是在Spring Boot中实现此类功能的好方法。

Spring Boot有一个built-in endpoint，它返回有关最近100个请求的信息，如下所示：

[{
    "timestamp": 1394343677415,
    "info": {
        "method": "GET",
        "path": "/trace",
        "headers": {
            "request": {
                "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8",
                "Connection": "keep-alive",
                "Accept-Encoding": "gzip, deflate",
                "User-Agent": "Mozilla/5.0 Gecko/Firefox",
                "Accept-Language": "en-US,en;q=0.5",
                "Cookie": "_ga=GA1.1.827067509.1390890128; ..."
                "Authorization": "Basic ...",
                "Host": "localhost:8080"
            },
            "response": {
                "Strict-Transport-Security": "max-age=31536000 ; includeSubDomains",
                "X-Application-Context": "application:8080",
                "Content-Type": "application/json;charset=UTF-8",
                "status": "200"
            }
        }
    }
},{
    "timestamp": 1394343684465,
    ...
}]

如果您的应用程序正在调用其他服务或查询数据库，请考虑使用Sniffy进行性能分析 - 它不仅会显示您在服务器上花费的时间，还会显示调用下游系统所花费的时间。查看实时演示here（检查顶部底部角落的黑色小部件）。

如果你的控制器是异步，请使用Aspect来获得正确和完整的执行时间。

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.Around;
import org.aspectj.lang.annotation.Aspect;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.context.request.RequestContextHolder;
import org.springframework.web.context.request.ServletRequestAttributes;

import javax.servlet.http.HttpServletRequest;
import java.util.Arrays;
import java.util.UUID;

@Aspect
@Component
public class LoggingAspect {

  static Logger log = LoggerFactory.getLogger(LoggingAspect.class);

  @Around("execution(* com.aakchoo.api.controller..*(..))")
  public Object profileExecutionTime(ProceedingJoinPoint joinPoint) throws Throwable {

    long start = System.currentTimeMillis();
    String className = joinPoint.getSignature().getDeclaringTypeName();
    String methodName = joinPoint.getSignature().getName();
    String apiName = className + "."+ methodName;
    HttpServletRequest request =
        ((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest();
    String requestId = UUID.randomUUID().toString();
    log.info("----->>>>>\nREQUESTED_ID: {}\nHOST: {} HttpMethod: {}\nURI: {}\nAPI: {}\nArguments: {}\n",
        requestId,
        request.getHeader("host"),
        request.getMethod(),
        request.getRequestURI(),
        apiName,
        Arrays.toString(joinPoint.getArgs()));

    Object result = joinPoint.proceed();
    long elapsedTime = System.currentTimeMillis() - start;
    log.info("<<<<<-----\nExecution Time: {} ms [REQUESTED_ID: {}] [API: {}]", elapsedTime,requestId,apiName);

    return result;
  }
}

将@EnableAspectJAutoProxy添加到Applciation类

@EnableAsync
@SpringBootApplication
@EnableAspectJAutoProxy
public class Application {
  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }
}

您的build.gradle需要以下

compile 'org.aspectj:aspectjweaver:1.8.10'
compile 'org.springframework.boot:spring-boot-starter-aop'

Answer 5

我们可以通过覆盖num = float(input("Enter a float number: ")) if num - int(num) >= 0.5: print(int(num) + 1) else: print(int(num))方法来使用Springboot InMemoryHttpTraceRepository

add()

也许您可以使用log4j并将日志配置为DEBUG
