将我的应用程序打包为 JAR

• 问答

我在 JDK 16 中开发了一个基于 dom4j 库的 Java 应用程序，它添加了一些特定的 XML 元素作为提供的 XML 文档中特定元素的子元素。输入 XML 文档的某些元素，以及我的应用程序在输入文档中创建和添加的 XML 元素的某些子元素，都包含希腊字符串作为内容。例如，这是输入 XML 文件的一个这样的元素：

<DecPlaHEA394>ΠΕΙΡΑΙΑΣ</DecPlaHEA394>

这里是我创建并添加到输入文档的 XML 元素：

<VEHDET>
  <FraNumVD1014>LATTCJCY7M1400121</FraNumVD1014>
  <VehCC4006>124</VehCC4006>
  <VehFue4007>ΒΕΝΖΙΝΗ ΑΜΟΛΥΒΔΗ</VehFue4007>
  <VehTyp4008>3</VehTyp4008>
  <VehEngTyp4009>DY152QMI-3C</VehEngTyp4009>
  <ProdYea4010>2021</ProdYea4010>
  <VecTra4023>DY125T-28D</VecTra4023>
  <VehFactyp4001>DY125T-28D</VehFactyp4001>
  <VehUseFl4015>0</VehUseFl4015>
  <ArImpDatVECDET01>20210426</ArImpDatVECDET01>
  <ImpCodVECDETGI>457</ImpCodVECDETGI>
  <CarDioEmiVECDET04>-</CarDioEmiVECDET04>
</VEHDET>

每当我从 eclipse 运行我的应用程序时，输出 XML 中的任何希腊语内容都显示为纯希腊语文本，与输入 XML 文件中的完全相同。昨天，在使用 Maven 程序集插件将我的应用程序打包到包含所有依赖项的“uberjar”之后，我注意到，当我通过从 Windows 终端执行上述 JAR 来运行它时，所有希腊语内容都显示为它们的 UTF- 8 在输出 XML 文件中进行编码（我需要在此处将其添加为屏幕截图，以便理解我面临的问题）：

将我的应用程序打包为 JAR

输入 XML 文件的编码是“utf-8”，但我注意在输出 XML 中使用相同的编码。通过将输入 XML 文件的 XML 内容复制到输出 XML 并添加提到的 XML 元素来生成输出 XML 的代码如下：

public int createOutputXML(int customsDeclaration,int howManyModels,ArrayList<InputFrameNumbersFileReader> inputFraNumFileReaders,ArrayList<ModelDescriptor> modelDescriptorsArray) {
    try {
        URL urlOfInputXMLFile = Paths.get(m_InputXMLFile).toUri().toURL();
        
        SAXReader reader = new SAXReader();
        Document document = reader.read(urlOfInputXMLFile);
        String encoding = document.getXMLEncoding();
        
        // Get the root element:
        Element root = document.getRootElement();
        
        // For each different model: 1 to howManyModels
        // - Find its respective GOOITEGDS: Find all the GOOITEGDS,store them in the list,and get them one at a time
        // - Find its respective TAXADDELE100: Same way
        // - Call writeVEHDATBlocksToXMLImportAndHomeUseCases() or writeVEHDATBlocksToXMLWarehousingCase() with the GOOITEGDS and the TAXADDELE100
        //   for the current model.
        
        // Get the node GOOITEGDS (parent node of these nodes)
        List<Element> gooIteGdsElemList = root.elements("GOOITEGDS");
        if ((gooIteGdsElemList != null))  {
