从jar导入java库类时，这被认为是静态链接吗？还是动态的？ [英] When importing a java library class from jar, is this considered static linking? or dynamic?

问题描述

说我的lib文件夹中有jcifs-1.3.14.jar，我有一个从库导入的类，并使用类似于

  import jcifs.smb。*; 
 NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication（domain，
 user，
 pass）; 
 SmbFile file = new SmbFile（path，auth）; 
 //在这里执行一些操作
  

以这种方式使用库时它被认为是：A）静态链接或B）动态链接OR C）别的东西

解决方案

如果你正在寻找关于在Java程序上应用各种软件许可证的信息，然后在Google上搜索<许可证名称> Java 通常会产生有用的命中。

例如 LGPL Java ，这是第一个命中。在这种特殊情况下，底线是：

链接到LGPL
库的应用程序不需要在$ b $下发布b LGPL。应用程序只需
按照LGPL的第6节
中的要求：允许
库的新版本与
应用程序链接;并允许反向
工程来调试这个。

只要图书馆在单独的JAR文件中提供，可以轻松替换，LGPL允许。

PS：我不是律师！如有疑问，请咨询。事实上，取决于你住在哪里，咨询一个人是有道理的，不管你有什么疑问。

say I have jcifs-1.3.14.jar in my lib folder, and I have a class that is importing from the library and uses the classes like:

import jcifs.smb.*;
NtlmPasswordAuthentication auth = new NtlmPasswordAuthentication(domain, 
                                                                 user, 
                                                                 pass);
SmbFile file = new SmbFile(path, auth);
// do some operations with the file here

When using the library in this fashion is it considered to be: A) Static Linking OR B) Dynamic Linking OR C) something else?

解决方案

If you are looking for information about applying various software licenses on Java programs, then searching Google for <license name> Java usually results in a useful hit.

E.g for LGPL Java, this is the first hit. In this particular case, the bottom line is:

Applications which link to LGPL libraries need not be released under the LGPL. Applications need only follow the requirements in section 6 of the LGPL: allow new versions of the library to be linked with the application; and allow reverse engineering to debug this.

I.e. as long as the library is provided in a separate JAR file that can be easily replaced, LGPL allows it.
