前言
在AOP切面注入RequestId,拦截Controller、Service方法,打印入参出参耗时等,方便排查问题。
可以在服务上通过RequestId查询一次调用链日志:
可以使用 Linux grep 命令查询日志:
grep 命令用于查找文件里符合条件的字符串。 日志文件太大无法直接 cat 查看,可以用grep 常用参数:- -A<显示行数> : 除了显示符合范本样式的那一列之外,并显示该行之后的内容。
- -C<显示行数> : 除了显示符合样式的那一行之外,并显示该行之前后的内容。
- -E : 将样式为延伸的正则表达式来使用。
代码
Controller
/** * @author lihaoyang * @date 2021/3/17 */ @RestController public class HiController { @Autowired HiServiceImpl hiService; @GetMapping("get") public String get(String msg) { String rs = hiService.getHi(msg); return rs; } }
Service
@Service public class HiServiceImpl { public String getHi(String msg) { return "service: >>>>> " + msg; } }
