## 使用 ##

在代码的第一行写：  
`//go:generate go-bindata -o=staticFile.go -pkg=packfile -tags=packfile ../resource/... ../config.yaml ../migrate/...`  
migrate这些目录需要在部署时放置在main程序二进制文件所在目录

//go:build packfile
    // +build packfile
    
    package packfile
    
    import (
    	"fmt"
    	"io/ioutil"
    	"os"
    	"path/filepath"
    	"strings"
    )
    
    //go:generate go-bindata -o=staticFile.go -pkg=packfile -tags=packfile ../resource/... ../config.yaml ../migrate/...
    
    func writeFile(path string, data []byte) {
        
    	// 如果文件夹不存在，预先创建文件夹
    	if lastSeparator := strings.LastIndex(path, "/"); lastSeparator != -1 {
        
    		dirPath := path[:lastSeparator]
    		if _, err := os.Stat(dirPath); err != nil && os.IsNotExist(err) {
        
    			os.MkdirAll(dirPath, os.ModePerm)
    		}
    	}
    
    	// 已存在的文件，不应该覆盖重写，可能在前端更改了配置文件等
    	if _, err := os.Stat(path); os.IsNotExist(err) {
        
    		if err2 := ioutil.WriteFile(path, data, os.ModePerm); err2 != nil {
        
    			fmt.Printf("Write file failed: %s\n", path)
    		}
    	} else {
        
    		fmt.Printf("File exist, skip: %s\n", path)
    	}
    }
    
    func init() {
        
    	for key := range _bindata {
        
    		filePath, _ := filepath.Abs(strings.TrimPrefix(key, "."))
    		data, err := Asset(key)
    		if err != nil {
        
    			// Asset was not found.
    			fmt.Printf("Fail to find: %s\n", filePath)
    		} else {
        
    			writeFile(filePath, data)
    		}
    	}
    }
