Maven，Tomcat，java.library.path和％PATH％：一种奇怪的爱情

标签： java windows maven tomcat jco

我一直在努力认识到当前使用Tomcat和外部库（JCo）的Java Maven项目正在发生什么。 出于某种原因，System.getProperty("java.library.path")结果与我的环境变量%PATH%中的路径不匹配（默认）。 我不打算更改java.library.path值或任何，我只想知道为什么 NOT DEFAULTING 到％PATH％变量。

以下是我如何确定它：

public static void main(String[] args) {
    for (String path : System.getProperty("java.library.path")) {
        System.out.println(path);
    }
}

上面的代码段会导致：

C:\Program Files\Java\jre1.8.0_131\bin C:\WINDOWS\Sun\Java\bin C:\WINDOWS\system32 C:\WINDOWS C:/Program Files/Java/jre1.8.0_131/bin/server C:/Program Files/Java/jre1.8.0_131/bin C:/Program Files/Java/jre1.8.0_131/lib/amd64 C:\ProgramData\Oracle\Java\javapath C:\Program Files\Docker\Docker\Resources\bin C:\Python27 C:\Python27\Scripts C:Program Files\Git\bin C:Program Files\Git\cmd \C:\Program Files (x86)\Intel\iCLS Client\ C:\Program Files\Intel\iCLS Client\ C:\Windows\system32 C:\Windows C:\Windows\System32\Wbem C:\Windows\System32\WindowsPowerShell\v1.0\ C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\DAL C:\Program Files\Intel\Intel(R) Management Engine Components\DAL C:\Program Files (x86)\Intel\Intel(R) Management Engine Components\IPT C:\Program Files\Intel\Intel(R) Management Engine Components\IPT C:\Users\Unknown\.dnx\bin C:\Program Files\Microsoft DNX\Dnvm\ C:\Program Files\Microsoft SQL Server\120\Tools\Binn\ C:\Program Files\Microsoft SQL Server\130\Tools\Binn\ C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit\ C:\Program Files (x86)\Microsoft Emulator Manager\1.0\ C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common C:\Program Files (x86)\Microsoft SQL Server\Client SDK\ODBC\110\Tools\Binn\ C:\Program Files (x86)\Microsoft SQL Server\120\Tools\Binn\ManagementStudio\ C:\Program Files (x86)\Microsoft SQL Server\120\Tools\Binn\ C:\Program Files\Git\cmd C:\Program Files (x86)\nodejs\ C:\WINDOWS\system32 C:\WINDOWS C:\WINDOWS\System32\Wbem C:\WINDOWS\System32\WindowsPowerShell\v1.0\ C:\Program Files (x86)\Skype\Phone\ C:\Program Files\Java\jdk1.8.0_112\bin D:\Arquivos de Programas\Apache Software Foundation\Maven 3.3.9\bin C:\Pro C:\Users\Unknown\AppData\Roaming\npm C:\Users\Unknown\AppData\Local\Microsoft\WindowsApps C:\Program Files\Eclipse Neon .

... echo %PATH%产生以下结果：

正如我们所看到的，%PATH%中的“C：\ WEEEEEEEEEEEIRD \ PAAAAAAAATHHHHHH \ FOR MAVEN EXAMPLE”未显示在java.library.path中。此路径包含项目所需的DLL。

可能有什么不对？非常感谢提前！
