stream closed 解决xssfworkbook

XSSFWorkbook在关闭之前需要手动调用close()方法，否则可能出现stream closed异常。该方法将释放与该workbook相关的所有资源，包括内存和磁盘空间。以下是一个代码示例：

try {
    XSSFWorkbook workbook = new XSSFWorkbook();
    // do some operations with the workbook
} finally {
    workbook.close();
如果使用try-with-resources语句，可以自动关闭XSSFWorkbook，避免stream closed异常：
try (XSSFWorkbook workbook = new XSSFWorkbook()) {
    // do some operations with the workbook
