在Golang中动态加载？ [英] Dynamic loading in Golang?

问题描述

我有一个共同的项目和小项目，这些项目在公共项目中扮演着连接器的角色。

我想创建一个通用项目，连接器开发我不需要修改常见项目中的代码。是否有可能在Go中动态加载结构，只知道该结构及其文件夹的路径（通过将此路径放在通用项目的文件中，并在运行时加载该结构）？

  connector1 
 connector1.go 
 / util 
 / domain 
 
 connectorN 
 connectorN.go 
 / domain 
 
 commonProject 
 main.go 
 config.ini 
  

结构config.ini

  Conector 
 name = connector1 
 path = .... / connector1 / connector1.go 
 
 Conector 
 name = connectorN 
 path = .... / connectorN / connectorN.go 
  

我知道在Java中使用这样的代码可以做到这一点，但我试图在Go中执行此操作。任何想法？

  Class.forName（String）
  

或

  ClassLoader.loadClass（String）：
  code> 




解决方案

我可以看到两种方法来实现您所描述的内容，但请记住， @icza指出，go会产生静态的二进制文件，所以你不能动态地加载外部库。



然而，你可以：



• 使用 cgo 与C代码交互，并加载外部库，即
  方式。 b $ b
• 使用 net / rpc 包让多个二进制文件相互沟通
  ，并根据需要加载这些文件。

I've got a common project and small projects which act such as connectors in the common project.

I want to create a common project such that when a new connector is developed I don’t have to modify code in the common project. Is it possible to dynamically load the structures in Go, only knowing the path (by putting this path in a file in common project and at runtime load that struct) of the struct and its folders?

connector1
  connector1.go
  /util
  /domain

connectorN
  connectorN.go 
  /domain

commonProject
   main.go
   config.ini

Structure config.ini

Conector
name = connector1
path = ..../connector1/connector1.go

Conector
name = connectorN
path = ..../connectorN/connectorN.go

I know that this is possible to do this in Java with code like this, but I am trying to do this in Go. Any ideas?

Class.forName(String) 

or

ClassLoader.loadClass(String):

解决方案

I can see two ways to achieve what you describe, but keep in mind, as @icza pointed out, that go produces static binaries, so you can't load external libraries dynamically.

You can, however:

• use cgo to interface with C code, and load external libraries that way.
• use the net/rpc package to have several binaries communicate with each other, and load those on demand.
