java - 为我的 java 应用程序创建可执行 jar 文件

Question

public class createExcel {

public  void write() throws IOException, WriteException {

        WorkbookSettings wbSettings = new WorkbookSettings();
        wbSettings.setLocale(new Locale("en", "EN"));
        WritableWorkbook workbook1 =Workbook.createWorkbook(new File(file), wbSettings);
        workbook1.createSheet("Niru ", 0);
        WritableSheet excelSheet = workbook1.getSheet(0);
        createLabel(excelSheet);
        createContent(excelSheet,list);
        workbook1.write();
        workbook1.close();
    }


 public void createLabel(WritableSheet sheet)throws WriteException {

WritableFont times10pt = new WritableFont(WritableFont.createFont("D:\font\trebuct"),8);

// Define the cell format

        times = new WritableCellFormat(times10pt);
        // Lets automatically wrap the cells
        times.setWrap(false);
        WritableFont times10ptBoldUnderline = new WritableFont(
        WritableFont.createFont("D:\font\trebuct"), 9, WritableFont.BOLD, false,
        UnderlineStyle.NO_UNDERLINE);
        timesBoldUnderline = new WritableCellFormat(times10ptBoldUnderline);

        sheet.setColumnView(0,15);
                sheet.setColumnView(1,13);

        // Write a few headers
        addCaption(sheet, 0, 0, "Business Date");
        addCaption(sheet, 1, 0, "Dealer ID");


    }
        private void createContent(WritableSheet sheet, ArrayList list) throws WriteException,RowsExceededException {
                // Write a few number
        for (int i = 1; i < 11; i++) {
                    for(int j=0;j<11;j++){
            // First column
            addNumber(sheet, i, j,1);
            // Second column
            addNumber(sheet, 1, i, i * i);
                    }
        }
            }
private void addCaption(WritableSheet sheet, int column, int row, String s)     throws RowsExceededException, WriteException {

        Label label;
        label = new Label(column, row, s, timesBoldUnderline);
                sheet.addCell(label);
    }

    private void addNumber(WritableSheet sheet,  int row,int column,
            Integer integer) throws WriteException, RowsExceededException {
        Number number;
        number = new Number(column,row, integer, times);
        sheet.addCell(number);
    }


public static void main(String[] args) {

        JButton myButton0 = new JButton("Advice_Report");
        JButton myButton1 = new JButton("Position_Report");
        JPanel bottomPanel = new JPanel();   
        bottomPanel.add(myButton0);
        bottomPanel.add(myButton1);  
        myButton0.addActionListener(this);
        myButton1.addActionListener(this);  
        createExcel obj=new  createExcel();
        obj.setOutputFile("c;\\temp\\swings\\jack.xls");
        try{
        obj.write();
        }catch(Exception e){}
}

等等。它工作正常。我有 jxl.jar 和 ojdbc14.jar 文件(需要这个 jar 文件来创建 Excelsheet 和数据库连接)和 createExcel.class(.class 文件)文件。如何将此代码制作为可执行 jar 文件。

Answer 1

有几种方式:

1. 创建一个 jar 文件并将您的类(没有依赖项)放在那里。使用一些工具(任何 IDE 都有)来执行此操作并指定具有 main 函数的类。您也可以从命令行手动执行此操作。当用户想要运行它时，他应该指定类路径，并且所有依赖项都应该在该类路径中。

2. 创建相同的 jar 并创建 .bat 或 .sh 文件，在其中设置类路径并运行您的 jar。

3. 使用一些特殊工具创建跨平台安装程序(但好的工具不是免费的)。
