如何检查用户在任何系统上的访问级别 [英] How to check access level of user on any system

问题描述

在我们的RCP应用程序中，我们在菜单贡献下新增了一个菜单作为命令。现在我们要根据登录到系统的用户来启用或禁用这个新菜单。基本上，我们只想为管理员登录启用菜单，而不是为任何其他用户启用菜单。

In our RCP application we have newly added a menu as command under menu contributions. Now that we want to enable or disable this new menu depending the user who has logged on to the system. Basically we want to enable the menu only for the Administrator login and not for any other user.

如何实现？

提前感谢

推荐答案

您可以检索登录的用户名称：

You can retrieve the logged in user's name as :

String user=System.getProperty("user.name"); 

您可以检索登录的用户详细信息 如java-forums.org中所述 ：

You can retrieve the logged in user detail as described in java-forums.org:

public static void ntSystemDetails() {

    com.sun.security.auth.module.NTSystem NTSystem = new com.sun.security.auth.module.NTSystem();

    System.out.println(NTSystem.getName());
    System.out.println(NTSystem.getDomain());
    System.out.println(NTSystem.getDomainSID());

    System.out.println(NTSystem.getImpersonationToken());
    System.out.println(NTSystem.getPrimaryGroupID());
    System.out.println(NTSystem.getUserSID());
    for (String group : NTSystem.getGroupIDs()) {
        System.out.println("Groups  " + group);
    }
}

如果您收到以下错误：

   NTSystem is not accessible due to restriction on required library ...
