Java后端开发——根据token写日志代码示例

@GetMapping("download/result")
@ApiOperation("提供手机号绑定结果给浏览器下载")             　　　　//Controller层代码                               

public Response<Boolean> downloadResultExcel(HttpServletRequest request) throws IOException {

　　String token = request.getHeader("Authorization");

　　return excelService.downloadResultExcel(token);

}

//    @GetMapping("download/result")
//    @ApiOperation("提供手机号绑定结果给浏览器下载")　　　　　　　　
    public Response<Boolean> downloadResultExcel(String token)throws IOException {　　　　//Service层代码
        String userIdStr = this.redisService.get(token);　　　　//调用redisService取得当前页面用户信息

        User user = this.userMapper.selectById(userIdStr);

        if (user==null || user.getIsDelete()==1){　　　　　　　　//判断该用户是否存在
            return new Response<>("导出手机号绑定信息日志写入失败");
        }else {
            if (operationLogService.addOperationLog(user.getId(),"导出手机号绑定信息成功",1).getCode().equals("500")){
                return new Response<>("导出手机号绑定信息日志写入失败");
            }
        }

        return new Response<>("",Response.SUCCESS_CODE,Boolean.TRUE);
    }
}
