日志怎么打？

1.在关键节点打日志
(1).请求入口
(2).结果响应
2.可能发生错误的节点打日志
3.日志不是越多越好，打日志也会消耗性能

  @RequestMapping("/add")public Boolean publishBlog(String title, String content, HttpServletRequest request) {log.info("publishBlog,接受参数：title:{},content:{}",title,content);/*** 1.参数校验* 2.获取当前登录用户* 3.博客发布*/if(!StringUtils.hasLength(title) || !StringUtils.hasLength(content)) {log.error("title or content 为空");return false;}String user_token = request.getHeader(Constant.USER_TOKEN_HEADER);Integer userId = JWTUtils.getUserIdFromToken(user_token);if(userId==null || userId<=0) {log.error("用户未空");return false;}BlogInfo blogInfo = new BlogInfo(title,content,userId);Integer result = blogService.publishBlog(blogInfo);if(result<1) {log.error("发布失败！");return false;}return true;}
