go-swagger 会自动查找程序 main 函数入口
然后生成对应的 swagger 文档
也就是说，endpoint 入口是可以，也应该被分开写在不同文件内的
main.go
// Package Helloworld API.
//
// The purpose of this service is to provide an application
// that is using plain go code to define an API

package main
import (
"log"
"net/http"
)
func main() {
http.HandleFunc("/hello", handlers.Hello)
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal(err)
}
}
HelloHandler.go
package handler
import (
"encoding/json"
"io"
"net/http"
)
