AOP实现项目日志收集

我们利用AOP实现项目的日志收集

  • 直接上代码

import javax.servlet.http.HttpServletRequest;
import java.util.Map;

        String header = request.getHeader("User-Agent");
        UserAgent userAgent = UserAgent.parseUserAgentString(header);
        log.info("【浏览器类型】:{},【操作系统】:{},【原始User-Agent】:{}", userAgent.getBrowser().toString(), userAgent.getOperatingSystem().toString(), header);
