java - Java 的批处理文件

Question

为了使用 USB 磁条阅读器在 PC 上接受信用卡，我公司在我们的门户网站上使用 Java。为了使磁条阅读器正常工作，我们的帮助台必须指导客户将 rxtxSerial.dll 和 RXTXcomm.jar 文件移动到 Windows 中相应的 bin 和 lib\ext 文件夹。我们还必须将两个 URL 添加到 Java 控制面板中的站点异常(exception)列表中。目前，这两个流程都涉及使用 GUI 并指导我们的客户在他们的计算机上完成此操作。

Java 对我来说并不是真正的强项。我正在尝试创建一个批处理文件(.dll 和 .jar 文件位于同一目录中)，该文件将自动执行这两个过程，以便用户所要做的就是运行批处理文件。然而，我遇到了一些我还没有完全准备好的问题。

1. 我需要能够让该文件适用于客户计算机上所有可能的 Java 安装路径。我可以为 32 位和 64 位 Java 提供单独的批处理文件。但是，并非每个客户的“C:\Program Files (x86)\Java”目录中都有 jre8 文件夹。有时，他们会使用类似 jre1.8.0_31 的东西来代替 jre8。我也需要批处理文件来解释这些差异。

2. 据我了解，sites.exceptions 文件存储在用户目录中包含的子目录中。问题是我需要能够创建一个批处理文件，该文件能够将当前用户的目录定位为完整文件路径的一部分。此外，我并不完全清楚如何从命令提示符编辑sites.exceptions。我想我可以有一个预先制作的异常文件，该文件可以复制到正确的目录(并且自然地覆盖任何当前现有的文件)。

我对 IT 领域很陌生，所以我不知道我的要求是否可行，或者我的解释是否正确。我真的很感激一些帮助。

我想这可能对你有帮助。该程序检测是否安装了 Java。它还检测 java 的版本等。

    rem ----------END JAVA SEARCH-----------------------------------------------------------------

现在我们已经找到了 java HomeDirectory，我们可以通过 java 执行我们的数据包。我们可以通过 cmd 使用 java，所以这应该很容易。

我们现在可以做什么的示例:

rem Make sure prerequisite environment variables are set
if not "%JAVA_HOME%" == "" goto gotJdkHome
if not "%JRE_HOME%" == "" goto gotJreHome
echo Neither the JAVA_HOME nor the JRE_HOME environment variable is defined
echo Service will try to guess them from the registry.
goto runAsUser
:gotJreHome
if not exist "%JRE_HOME%\bin\java.exe" goto noJavaHome
if not exist "%JRE_HOME%\bin\javaw.exe" goto noJavaHome
goto runAsUser
:gotJdkHome
if not exist "%JAVA_HOME%\jre\bin\java.exe" goto noJavaHome
if not exist "%JAVA_HOME%\jre\bin\javaw.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\javac.exe" goto noJavaHome
if not "%JRE_HOME%" == "" goto runAsUser
set "JRE_HOME=%JAVA_HOME%\jre"
goto runAsUser
:noJavaHome
echo The JAVA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program
echo NB: JAVA_HOME should point to a JDK not a JRE
goto end

Here comes the main code that let's you run your java applet/program

:doInstall
rem Install the service
echo Installing the service '%SERVICE_NAME%' ...
echo Using PROGRAM_HOME:    "%YOUR_PROGRAM_HOME_HERE%"
echo Using JAVA_HOME:        "%JAVA_HOME%"
echo Using JRE_HOME:         "%JRE_HOME%"

rem Use the environment variables as an example
rem Each command line option is prefixed with PR_

set "PR_INSTALL=%EXECUTABLE%"

rem Add another jar or java file next to it with a semicolon. (still in the quotes)

set "PR_CLASSPATH=%YOUR_PROGRAM_HOME_HERE%\javawishprogram.jar;%YOUR_PROGRAM_HOME_HERE%\MaybeASecondoneIfYouwant.jar"
rem Set the server jvm from JAVA_HOME
set "PR_JVM=%JRE_HOME%\bin\server\jvm.dll"

rem Here you can go further on the JVM or not, you can map out your options.
if exist "%PR_JVM%" goto foundJvm

rem Set the client jvm from JAVA_HOME
set "PR_JVM=%JRE_HOME%\bin\client\jvm.dll"
if exist "%PR_JVM%" goto foundJvm
set PR_JVM=auto
:foundJvm
echo Using JVM:              "%PR_JVM%"
rem Here you're launching the main programme.
"%EXECUTABLE%" //IS//%SERVICE_NAME% --StartClass programJava.startup.Bootstrap --StartParams start --StopParams stop --Startup auto

You can do even more with this. But I'll let it to your imagination.

这个脚本是我从 CATALINA 借来的这是完整的脚本:
