OSGI/Equinox Bundle Resource：URI Scheme不是文件

我有一個插件，我在Equinox容器中運行。在插件jar中，包含一個/ bin目錄，其中包含我想運行的可執行文件和相關的共享庫。我試圖讓可執行文件（/ bin）中的父路徑，但我收到以下異常：OSGI/Equinox Bundle Resource：URI Scheme不是文件

下面的代碼顯示了我的構造函數試圖獲取資源變量的父路徑（如/ bin）。在新的File（binPath.getURI（））命令中拋出異常。資源變量使用下面的spring context定義傳入。

public Launcher(Resource resource) { 
    try { 
     binFile = resource.getURL().getFile();    
     String binPath = new File(binPath.getURI()).getParentFile().getAbsolutePath(); 
    } catch (IOException e) { 
     // TODO Auto-generated catch block 
     System.out.println("TestLauncher Exception found"); 
     e.printStackTrace(); 
    } 
}

Spring上下文定義：

<bean id="testResource" class="org.springframework.core.io.ClassPathResource"> 
    <constructor-arg value="\bin\test" /> 
</bean>

我認爲，所有你需要做的是一個文件URI，如提供路徑值：

<bean id="testResource" class="org.springframework.core.io.ClassPathResource"> 
    <constructor-arg value="file:../test" /> 
</bean>

在這裏，我只需根據我認爲是您的類路徑來猜測您需要的路徑即可。您可能需要嘗試使用不同的路徑值才能使其工作。

祝你好運！
