使用servlet在mule esb項目中獲取java變壓器中的文件路徑esb

File schemaLocation = new File("/home/localpc/servletaddequi/src/main/resources/BackupSample/DEMO.xsd")

如果我如上所述傳遞文件路徑，我能夠獲取文件。但我想只從項目中傳遞文件的路徑，我怎麼能通過文件的路徑？如果我通過如下文件路徑：使用servlet在mule esb項目中獲取java變壓器中的文件路徑esb

File schemaLocation = new File("/foldername/filename.xsd");

它會產生誤差：

Failed to read schema document 'file:/BackupSample/DEMO.xsd', because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

您可以添加您flow.xml。爲什麼你需要在Java轉換器中使用一個文件。我有點困惑，原因。 –

請參閱從這個帖子答案：mule read single file from classpath during flow，你可以使用Thread.currentThread().getContextClassLoader().getResource("filename.xsd")獲得URL類。

因此你可以試試下面的代碼：

URL url = Thread.currentThread().getContextClassLoader().getResource("filename.xsd"); 
File schemaLocation = new File(url.getFile());
