最近看到了热加载，相关的，就搜索了goland实现热加载

发现了一个插件realize

https://github.com/oxequa/realize

然后，为了自己撸代码更方便，配合gin写个教程

1.准备

go get github.com/oxequa/realize
go get github.com/gin-gonic/gin

2.然后开始

package main

import (
	"github.com/gin-gonic/gin"
	"net/http"
)

func main() {
	r := gin.Default()
	r.GET("/sayHello/:name", SayHello)
	r.GET("/test/:id/:name", getUser)
	r.Run(":9090")
}

//http://localhost:9090/test/1/dong
func getUser(c *gin.Context) {
	id := c.Param("id")
	name := c.Param("name")
	json := gin.H{
		"data": id,
		"name": name,
	}
	c.JSON(http.StatusOK, json)
}

//http://localhost:9090/sayHello/dong
func SayHello(c *gin.Context) {
	name := c.Param("name")
	c.String(http.StatusOK, "hello,"+name)
	//c.String(http.StatusOK, "change,"+name)
}

3.项目目录

4.其中.r开头文件都是生成的，生成步骤如下：

terminal运行：
realize init
一直next就行，可以按需配置

生成.realize.yaml后
terminal运行：
realize start

5.启动后如图

6.访问http://localhost:9090/sayHello/dong

7.然后更改方法内的内容

8.提示重新build并且重启了 

 9.然后重新访问http://localhost:9090/sayHello/dong

10.这样就是简单的实现了热加载代码改变，大家可以互相讨论，我也是第一次用

备注，把.realize.yaml分享一下
