请问是否有搭建 easy_note 项目的流程

Is your feature request related to a problem? Please describe.

刚刚了解到了 gorm、kitex、hertz 框架的强大之处，但它们的教程往往是孤立的，只涉及各自的单独使用。我觉得 easy_note 这个项目很适合将这三个框架串起来，但只有 quick start，而没有使用这三个框架逐渐构建出这个项目的教程。

Describe the solution you'd like

希望有这样一个教程：使用 gorm、kitex、hertz 一步一步构建出这个笔记项目，增强自身的一些自信心。

如何通过kitex命令生成类似bizdemo/easy_note中的目录结构

kitex如何指定生成service的路径，从而类似easy_note中的目录结构一样。使用常规的kitex -service demo demo.thrift只能生成这样的目录结构
.
├── build.sh // 服务的构建脚本，会创建一个名为 output 的目录并生成启动服务所需的文件到里面
├── handler.go // 用户在该文件里实现 IDL service 定义的方法
├── kitex_gen // IDL 内容相关的生成代码
│ ├── base // base.thrift 的生成代码
│ │ ├── base.go // thriftgo 的产物，包含 base.thrift 定义的内容的 go 代码
│ │ └── k-base.go // kitex 在 thriftgo 的产物之外生成的代码
│ └── demo // demo.thrift 的生成代码
│ ├── demo.go // thriftgo 的产物，包含 demo.thrift 定义的内容的 go 代码
│ ├── k-demo.go // kitex 在 thriftgo 的产物之外生成的代码
│ └── demoservice // kitex 为 demo.thrift 里定义的 demo service 生成的代码
│ ├── demoservice.go // 提供了 client.go 和 server.go 共用的一些定义
│ ├── client.go // 提供了 NewClient API
│ └── server.go // 提供了 NewServer API
├── main.go // 程序入口
└── script // 构建脚本
└── bootstrap.sh // 服务的启动脚本，会被 build.sh 拷贝至 output 下

而easy_note中的代码结构中通过kitex生成的script/*、main.go和handler.go与kitex_gen不在同一个目录下，这是怎么做到的，是自己复制的吗，那这样每次都需要自己手动修改handler.go中的包名很麻烦啊

kitex有go调用Java的示例吗

Proposal: Build an API Gateway Based on CloudWeGo Projects

Goal

The primary goal of this proposal is to implement a demo API Gateway on Hertz which accepts HTTP requests encoded in JSON format and uses the Generic-Call feature of Kitex to translate these requests into Thrift binary format requests. The API Gateway will then forward the request to one of the backend RPC servers discovered from the registry center.

Requirements and Deliverables

1. Implement an API Gateway that accepts HTTP requests with JSON-encoded bodies.
2. Use the Generic-Call feature in Kitex to translate JSON requests into Thrift binary format.
3. Integrate a load balancing mechanism to distribute requests among backend RPC servers.
4. Integrate a service registry and discovery mechanism for the API Gateway and RPC servers.
5. Develop backend RPC servers using Kitex for testing the API Gateway.
6. Document the project, including design decisions, implementation details, and usage instructions.

You're encouraged to post your implementation here for others' reference.

使用kitex命令自动生成代码，.thrift文件能够正常生产, .proto文件就会报错

具体错误如下：
Expect the IDL file to have an extension of '.thrift'. Got 'user.proto'.

Kitex version:

希望提供 Trans 使用 gonet 的示例。

1. 文档 https://www.cloudwego.io/zh/docs/kitex/tutorials/framework-exten/transport/ 提供了定制传输层的说明，比较抽象，作为框架使用者不知道怎么用。
2. changelog https://www.cloudwego.io/zh/blog/2022/08/26/kitex-v0.4.0-%E7%89%88%E6%9C%AC%E5%8F%91%E5%B8%83/ 提到 v0.4.0 支持了 gonet 作为传输层，只说在 window 场景作为默认的传输层。但没有说明如何强制指定。

诉求：

1. https://www.cloudwego.io/zh/docs/kitex/tutorials/framework-exten/transport/ 文档添加如何使用 gonet 配置的示例。
2. example 代码库添加关于传输层配置的示例，比如，添加一个可运行的 demo， 这个 demo 配置使用 gonet 作为传输层。

请问如果三个模块分别用Docker打包，kitex容器间的服务注册发现要如何实现呢？

本地环境下的注册发现是可以实现的，但是打包成容器运行之后就不行了。

请问windows环境下如何把easy_note项目网络库替换成gonet

netpoll不支持windows，请问如何进行替换。另外请问是否有支持windows的计划？
