[alibaba/easyexcel]1.1.1版本读文件，使用ExcelReader不同构造操作时有的报错

我分别使用了里面的5种构造方法，在1.1.1版本中有三个方法标识过时，这两个方法可以完成文件读取操作；但是，目前未过时的两个构造却不能完成操作。查看了源码，发现跟过时的两个构造方法是对应的，只是获取ExcelTypeEnum的方式不同，但却报错： 测试代码： ` @Test public void importExcel() throws IOException {

    try (InputStream inputStream = new FileInputStream(BASE_PATH + "scheduling.xlsx")) {
        MyExcelListener excelListener = new MyExcelListener();
        // AnalysisParam param = new AnalysisParam(inputStream, ExcelTypeEnum.XLSX, excelListener);
        // ExcelReader reader = new ExcelReader(param, excelListener);
        ExcelReader reader = new ExcelReader(inputStream, null, excelListener);
        // ExcelReader reader = new ExcelReader(inputStream, null, excelListener,true);
        // ExcelReader reader = new ExcelReader(inputStream, ExcelTypeEnum.XLSX, null, excelListener);
        // ExcelReader reader = new ExcelReader(inputStream, ExcelTypeEnum.XLSX, null, excelListener,true);

        List<Sheet> sheets = reader.getSheets();
        for (Sheet sheet : sheets) {
            reader.read(sheet);
        }

        return;
    }
} `

错误如下： ` com.alibaba.excel.exception.ExcelAnalysisException: Analyse excel occur file error fileType XLSX

几个构造方法： ` // 可以完成 @Deprecated public ExcelReader(InputStream in, ExcelTypeEnum excelTypeEnum, Object customContent, AnalysisEventListener eventListener) { this(in, excelTypeEnum, customContent, eventListener, true); }

我也碰到了这个问题, 测试了以下三种情况, 如果使用未过期的方法, 则要套上 BufferedInputStream

  • FileInputStream + 指定文件类型, 可以读取(使用过期的构造方法)
  • BufferedInputStream(FileInputStream) + 不指定文件类型, 可以读取
  • FileInputStream + 不指定文件类型, 抛出异常

具体代码如下, 

    @Test
    public void test1() throws Exception {
        // FileInputStream + 指定文件类型, 可以读取
        InputStream inputStream = new FileInputStream("TestData/excel/221.xlsx");

        try {
            ExcelReader reader = 
                new ExcelReader(inputStream, ExcelTypeEnum.XLSX, null, new AnalysisEventListener<List<String>>() {...});

            reader.read();
        } catch (Exception e) {
            e.printStackTrace();

        } finally {
            try {
                inputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

    @Test
    public void test2() throws Exception {
        // BufferedInputStream(FileInputStream) + 不指定文件类型, 可以读取
        InputStream inputStream = new BufferedInputStream(new FileInputStream("TestData/excel/221.xlsx"));

        // FileInputStream + 不指定文件类型, 抛出异常:
        // InputStream inputStream = new FileInputStream("TestData/excel/221.xlsx");
        try {
            ExcelReader reader = 
                new ExcelReader(inputStream, null, new AnalysisEventListener<List<String>>() {...});

            reader.read();
        } catch (Exception e) {
            e.printStackTrace();

        } finally {
            try {
                inputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }

如果是jdk>=1.8的话可以替换成poi4.0.0即可解决，有可能是poi的bug导致的

  • org.apache.poi poi-ooxml 4.0.0 
    <dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.0.0</version>
</dependency>
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-compress</artifactId>
    <version>1.18</version>
</dependency>

FileMagic.valueOf需要读取8个byte来判定文件类型，这个peek操作会影响原始的inputStream，导致后续真正读取文件的时候报错

bug修正之前可以传 BufferedInputStream 进去就不会有问题

@vivisidea 正解，问题应该就是出在这里。

ExcelReader excelReader = EasyExcelFactory.getReader(inputStream,excelListener); List sheets = excelReader.getSheets();

1.1.2-beta2处理了这个问题，但是如果是03版excel需要在输入流左一层new BufferedInputStream(new FileInputStream("/xxxx/xxx/77.xls")确保markSupported 返回true

1.1.2-beta5，读取03版excel使用new BufferedInputStream(new FileInputStream("/xxxx/xxx/77.xls")读取依然会java.lang.NoClassDefFoundError: org/apache/poi/poifs/filesystem/FileMagic
