[alibaba/easyexcel]excel 导出出现数组越界

触发场景描述 在本地、开发环境都能够正常导出excel文件在测试环境中使用时无法正常导出 触发Bug的代码

   response.setContentType("application/vnd.ms-excel");
    response.setCharacterEncoding("utf-8");
    fileName = URLEncoder.encode(fileName, "UTF-8");
    response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".xlsx");
    EasyExcel.write(response.getOutputStream(), clazz)
        .sheet("Sheet1")
        .doWrite(datas);

提示的异常或者没有达到的效果 [2019-11-26 16:38:37.444] [http-nio-8068-exec-5] [ERROR] [] DirectJDKLog.log:175 - Servlet.service() for servlet [dispatcherServlet] in context with path [/ed/api] threw exception [Request processing failed; nested exception is java.lang.ArrayIndexOutOfBoundsException: 0] with root cause java.lang.ArrayIndexOutOfBoundsException: 0 at sun.font.CompositeFont.getSlotFont(CompositeFont.java:340) at sun.font.CompositeGlyphMapper.initMapper(CompositeGlyphMapper.java:81) at sun.font.CompositeGlyphMapper.(CompositeGlyphMapper.java:62) at sun.font.CompositeFont.getMapper(CompositeFont.java:398) at sun.font.CompositeFont.canDisplay(CompositeFont.java:424) at java.awt.Font.canDisplayUpTo(Font.java:2063) at java.awt.font.TextLayout.singleFont(TextLayout.java:470)

应该是你的测试环境缺少了一些字体、或者字体相关的配置导致的参考资料

可能是最后一行什么都没写，但是被识别到了，可是尝试把数据后面的空白行删掉，再重新选择试试看

与数据无关，和运行机器相关

    ExcelWriterBuilder write = EasyExcel.write(new FileOutputStream(new File("")));
    write.registerWriteHandler(new WorkbookWriteHandler(){
        @Override
        public void beforeWorkbookCreate() {}
        @Override
        public void afterWorkbookCreate(WriteWorkbookHolder writeWorkbookHolder) {
            Workbook workbook = writeWorkbookHolder.getWorkbook();
            Font font = workbook.getFontAt(0);
            font.setFontName("FontName");
        }
    });
    write.sheet().doWrite(objects);
