java.io.IOException：流已关闭，但仅当从jar运行时

标签： java

当您直接从类中运行程序时，该程序将完美运行。但是，当使用cmd jar命令将程序创建到jar中时，启动程序时总是会出现运行时错误，并且程序也永远永远陷入循环。抱歉，我不能告诉您匹配的内容，我对Java很陌生。

这是导致问题的方法：

private static void pinyin()
{
    try
    {
        HanyuPinyinOutputFormat format = new HanyuPinyinOutputFormat();
        format.setCaseType(HanyuPinyinCaseType.LOWERCASE);
        format.setToneType(HanyuPinyinToneType.WITH_TONE_MARK);
        format.setVCharType(HanyuPinyinVCharType.WITH_U_UNICODE);

        for (int i = 0; i < size; i++)
        {
            if (!lines[i].equals(""))
            {
                lines[i] += " ";
            }
            String[] part = lines[i].split("#");
            part[2] = "";
            for (int y = 0; y < part[0].length(); y++)
            {

                String st = PinyinHelper.toHanyuPinyinStringArray(part[0].charAt(y), format)[0];
                part[2] = part[2] + st + " ";

            }
            lines[i] = part[0] + "#" + part[1] + "#" + (part[2].charAt(0) + "").toUpperCase() + part[2].substring(1, part[2].length() - 1);
        }
    } catch (Exception e)
    {
        System.out.println("Runtime Error" + e);
    }
}

它似乎是引起错误的行String st = PinyinHelper.toHanyuPinyinStringArray(part[0].charAt(y), format)[0];。 当我从罐子里跑出来的时候，我得到的错误是：

这就是我用来创建罐子的方法：

jar -cmf *.mf SortRandomDeletePin.jar *.class net\*

请您尽一切可能帮助我，我很沮丧。

还请注意，我的程序从另一个jar导入了一个类。

答案 0 :(得分：0)

从ChineseToPinyinResource的代码中，您可以看到类路径（*）中必须有两个文件，即/pinyindb/unicode_to_hanyu_pinyin.txt和/pinyindb/multi_pinyin.txt。

private void initializeResource() {
    try {
        final String resourceName = "/pinyindb/unicode_to_hanyu_pinyin.txt";
        final String resourceMultiName = "/pinyindb/multi_pinyin.txt";

        setUnicodeToHanyuPinyinTable(new Trie());
        getUnicodeToHanyuPinyinTable().load(ResourceHelper.getResourceInputStream(resourceName));

        getUnicodeToHanyuPinyinTable().loadMultiPinyin(ResourceHelper.getResourceInputStream(resourceMultiName));

        getUnicodeToHanyuPinyinTable().loadMultiPinyinExtend();

    } catch (FileNotFoundException ex) {
        ex.printStackTrace();
    } catch (IOException ex) {
        ex.printStackTrace();
    }
}

请确保在运行时这些文件及其正确路径在类路径中可用。

（*）：ResouceHelper类执行ResourceHelper.class.getResourceAsStream(resourceName)。
