go-project-sample's Issues

有计划添加swaggar, casbin的功能吗? 像 gin-admin

如何更好的分离业务逻辑

https://www.infoq.cn/article/4TAWp8YNYcVD4t046EGd
阅读这篇文章过来，跟文章中的改进：分离业务逻辑这一层还有点差距

老板，启动有点问题

老板，我是ubuntu18.04。编译都成功了，就http://localhost:8080/product/1不能访问

我用docker-compose up 发现如下问题：
level=warn ts=2020-11-09T07:26:57.142Z caller=notify.go:674 component=dispatcher receiver=email integration=email[0] msg="Notify attempt failed, will retry later" attempts=1 err="establish connection to server: dial tcp: address tcp/port: unknown port"
level=error ts=2020-11-09T07:27:17.143Z caller=dispatch.go:309 component=dispatcher msg="Notify for alerts failed" num_alerts=4 err="email/email[0]: notify retry canceled after 7 attempts: establish connection to server: dial tcp: address tcp/port: unknown port"
这两个找不到端口

结构中可以添加个路由层吗？

如果再添加个路由层感觉结构更完美。另外感谢分享！

无法运行项目

不知是哪里不对?

make docker-compose报错

克隆下项目后，直接cd go-project-sample/下运行make docker-compose，发生报错:
couldn't open import "grafonnet-lib/grafonnet/grafana.libsonnet": no match locally or in the Jsonnet library paths

发现下面这个路径下是空的:
go-project-sample/scripts/grafana/grafonnet-lib/

建议把https://github.com/grafana/grafonnet-lib/tree/master/grafonnet文件夹直接copy进去，能正常运行。

codahale/hdrhistogram repo url has been transferred under the github HdrHstogram umbrella

Problem

The codahale/hdrhistogram repo has been transferred under the github HdrHstogram umbrella with the help from the original author in Sept 2020 (new repo url https://github.com/HdrHistogram/hdrhistogram-go). The main reasons are to group all implementations under the same roof and to provide more active contribution from the community as the original repository was archived several years ago.

The dependency URL should be modified to point to the new repository URL. The tag "v0.9.0" was applied at the point of transfer and will reflect the exact code that was frozen in the original repository.

If you are using Go modules, you can update to the exact point of transfer using the @v0.9.0 tag in your go get command.

go mod edit -replace github.com/codahale/hdrhistogram=github.com/HdrHistogram/[email protected]

Performance Improvements

From the point of transfer, up until now (mon 16 aug 2021), we've released 3 versions that aim support the standard HdrHistogram serialization/exposition formats, and deeply improve READ performance.
We recommend to update to the latest version.
