在注册表中的环境中添加多个值并在Java应用程序中进行检索 [英] Adding multiple values to an environment in registry and retrieving in Java application

问题描述

我正在使用procrun将Java应用程序作为服务运行.

I am using procrun to run a java application as a service.

我使用以下方法设置路径:

I used following to set path:

set PATH="dir1;dir2;%PATH%"
procrun.exe //US//%SERVICE_NAME% ++Environment PATH=%PATH%

将注册表中的环境值更新为:

which updates environment value in registry as:

但是，在我的Java应用程序中，当我尝试获取 PATH 的值时:

But, in my Java application when I try to get the value of PATH:

System.getenv("PATH")

我仅获得第一个值(即上述情况下的dir1.如果将路径设置为 dir2; dir1;％PATH％，则仅获得dir2)

I get only the first value ( i.e. dir1 in above case. If I set the path to dir2;dir1;%PATH%, I get only dir2)

我是通过错误的方式检索还是以错误的方式进行设置?

Am I retrieving in a wrong way or setting in a wrong way?

推荐答案

您的问题是由于-Environment 选项中缺少引号引起的:

Your problem is caused by the lack of quoting in the --Environment option:

将以key = value形式提供给服务的环境变量列表.它们用#或;分隔.人物.如果您需要嵌入#或;值中的字符将它们放在单引号内.

List of environment variables that will be provided to the service in the form key=value. They are separated using either # or ; characters. If you need to embed either # or ; character within a value put them inside single quotes.

(请参见 Procrun文档).

由于Windows将％PATH％扩展为; 分隔的路径的列表，因此需要使用:

Since Windows expands %PATH% to a list of ;-separated paths, you need to use:

procrun.exe //US//%SERVICE_NAME% ++Environment 'PATH=%PATH%'

或 PATH ='％PATH'(如果愿意).将单引号字符分成; 分隔的参数列表后，将其从参数字符串中剥离(请参见

or PATH='%PATH' if you prefer. The single quote character is stripped from the parameter string after breaking it into a ;-separated list of parameters (cf. source code). Hence there might be a problem if you have single quotes in the name of a folder.

编辑:procrun还接受双引号(未去除)的引用，并且您的 PATH 变量包含引号，但cmd.exe的魔法将其删除.

Edit: procrun also accepts quoting through double quotes (which are not stripped) and your PATH variable contains quotes, but the magic of cmd.exe strips them away.
