需求

框架需要记录每一个HTTP请求的信息,包括请求路径、请求参数、响应状态、返回参数、请求耗时等信息

Spring Boot Filter方式

1. 添加 HttpTraceFilter

import com.alibaba.fastjson.JSON;
import io.micrometer.core.instrument.MeterRegistry;
import lombok.Data;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.io.IOUtils;
import org.springframework.core.Ordered;
import org.springframework.http.HttpStatus;
import org.springframework.web.filter.OncePerRequestFilter;
import org.springframework.web.util.ContentCachingRequestWrapper;
import org.springframework.web.util.ContentCachingResponseWrapper;
import org.springframework.web.util.WebUtils;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;
import java.time.LocalDateTime;
import java.util.Objects;

/**

 */
@Slf4j
public class HttpTraceLogFilter extends OncePerRequestFilter implements Ordered {

    // 配置要记录请求的路径前缀
    private static final String NEED_TRACE_PATH_PREFIX = "/";
    // 忽略为multipart/form-data的ContentType的请求
    private static final String IGNORE_CONTENT_TYPE = "multipart/form-data";

    private final MeterRegistry registry;

    public HttpTraceLogFilter(MeterRegistry registry) {
        this.registry = registry;
    }


    @Override
    public int getOrder() {
        return Ordered.LOWEST_PRECEDENCE - 10;
    }

    @Override
    protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain)
            throws ServletException, IOException {
        if (!isRequestValid(request)) {
            filterChain.doFilter(request, response);
            return;
        }
        if (!(request instanceof ContentCachingRequestWrapper)) {
            request = new ContentCachingRequestWrapper(request);
        }
        if (!(response instanceof ContentCachingResponseWrapper)) {
            response = new ContentCachingResponseWrapper(response);
        }
        int status = HttpStatus.INTERNAL_SERVER_ERROR.value();
        long startTime = System.currentTimeMillis();
        try {
            filterChain.doFilter(request, response);
            status = response.getStatus();
        } finally {
            String path = request.getRequestURI();
            if (path.startsWith(NEED_TRACE_PATH_PREFIX) && !Objects.equals(IGNORE_CONTENT_TYPE, request.getContentType())) {
                // 1. 记录日志
                log.info("---------- 请求日志开始 ----------");
                log.info("请求路径:{}", path);
                log.info("请求方法:{}", request.getMethod());
                log.info("请求IP:{}", request.getRemoteAddr());
                log.info("请求时间:{}", LocalDateTime.now().toString());
                long latency = System.currentTimeMillis() - startTime;
                log.info("请求耗时:{} ms", latency);
                log.info("请求参数:{}", JSON.toJSONString(request.getParameterMap()));
                log.info("请求Content-Type:{}", request.getContentType());
                log.info("请求Body:{}", getRequestBody(request));
                log.info("响应状态:{}", status);
                log.info("响应Body:{}", getResponseBody(response));
                log.info("---------- 请求日志结束 ----------");
            }
            updateResponse(response);
        }
    }

    private boolean isRequestValid(HttpServletRequest request) {
        try {
            new URI(request.getRequestURL().toString());
            return true;
        } catch (URISyntaxException ex) {
            return false;
        }
    }

    private String getRequestBody(HttpServletRequest request) {
        String requestBody = "";
        ContentCachingRequestWrapper wrapper = WebUtils.getNativeRequest(request, ContentCachingRequestWrapper.class);
        if (wrapper != null) {
            try {
                requestBody = IOUtils.toString(wrapper.getContentAsByteArray(), wrapper.getCharacterEncoding());
            } catch (IOException e) {
                // NOOP
            }
        }
        return requestBody;
    }

    private String getResponseBody(HttpServletResponse response) {
        String responseBody = "";
        ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        if (wrapper != null) {
            try {
                responseBody = IOUtils.toString(wrapper.getContentAsByteArray(), wrapper.getCharacterEncoding());
            } catch (IOException e) {
                // NOOP
            }
        }
        return responseBody;
    }

    private void updateResponse(HttpServletResponse response) throws IOException {
        ContentCachingResponseWrapper responseWrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
        Objects.requireNonNull(responseWrapper).copyBodyToResponse();
    }


}

2. 添加 HttpTraceConfiguration

import com.swstsoft.camera.server.config.filter.HttpTraceLogFilter;
import io.micrometer.core.instrument.MeterRegistry;
import org.springframework.boot.autoconfigure.condition.ConditionalOnWebApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * 功能描述:Http日志跟踪配置
 *
 * @author lq
 * @date 2019-09-06 09:23
 */
@Configuration
@ConditionalOnWebApplication
public class HttpTraceConfiguration {

    @ConditionalOnWebApplication(type = ConditionalOnWebApplication.Type.SERVLET)
    static class ServletTraceFilterConfiguration {

        @Bean
        public HttpTraceLogFilter httpTraceLogFilter(MeterRegistry registry) {
            return new HttpTraceLogFilter(registry);
        }

    }

}
