如何在 Spring Boot 中记录 Rest Web 服务所花费的时间？

Question

我正在使用 Spring Boot 编写 Web Rest Web 服务。

我想记录我的网络服务处理请求所花费的时间。我还想记录标头、方法和调用的 URI。

几个月前我在我的球衣网络服务中做了类似的事情 ContainerRequestFilter and ContainerResponseFilter filter() method.

另外，AOP 是更好还是过滤器？

Answer 1

您是否尝试过这样的基本过滤器？

 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
    }
}

编辑：（感谢@suren-aznauryan）现在，它使用 Instant 和 Duration 并避免 System.currentTimeMillis() -c7fed.2b-

 import java.io.IOException;
import java.time.Duration;
import java.time.Instant;
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 {
        Instant start = Instant.now();
        try {
            chain.doFilter(req, resp);
        } finally {
            Instant finish = Instant.now();
            long time = Duration.between(start, finish).toMillis();
            LOGGER.trace("{}: {} ms ", ((HttpServletRequest) req).getRequestURI(),  time);
        }
    }

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

Spring Boot：日志记录拦截器

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/*");
  }
}
