我看ExcelBuilderImpl.addContent()方法里面有
int rowNum = this.context.getCurrentSheet().getLastRowNum();
这么一个方法，但是我读取已经保存好的Excel，结果rowNum还是从0开始，这个地方可以帮忙看下吗？
我这边的测试方法是，对同一个Excel，执行多次输出。

我用的是mac系统，把官方的例子拷贝过来执行，报下面的错误，莫名其妙，我也不知道错误中那个文件为什么找不到，这个文件不是我的，应该是执行过程中生成的文件。
java.io.FileNotFoundException: /var/folders/p4/ytdlw57579d6tf7fndxzj84r0000gn/T/easyexcel/-4992373293564731499/xl/sharedStrings.xml (No such file or directory) at java.io.FileInputStream.open0(Native Method) at java.io.FileInputStream.open(FileInputStream.java:195) at java.io.FileInputStream.<init>(FileInputStream.java:138) at java.io.FileInputStream.<init>(FileInputStream.java:93) at com.alibaba.excel.read.SaxAnalyserV07.initSharedStringsTable(SaxAnalyserV07.java:221) at com.alibaba.excel.read.SaxAnalyserV07.start(SaxAnalyserV07.java:158) at com.alibaba.excel.read.SaxAnalyserV07.<init>(SaxAnalyserV07.java:61) at com.alibaba.excel.read.ExcelAnalyserImpl.getSaxAnalyser(ExcelAnalyserImpl.java:28) at com.alibaba.excel.read.ExcelAnalyserImpl.analysis(ExcelAnalyserImpl.java:49) at com.alibaba.excel.ExcelReader.read(ExcelReader.java:55)

目前，从RowModel中获取字段的方式是使用getDeclaredFields，这会导致只能获取到该类的字段，获取不到从父类继承下来的字段。该代码位于/com/alibaba/excel/metadata/ExcelHeadProperty.java

/**
     * 初始化每列
     */
    private void initColumnProperties() {
        if (this.headClazz != null) {
            Field[] fields = this.headClazz.getDeclaredFields();
            List<List<String>> headList = new ArrayList<List<String>>();
            for (Field f : fields) {
                initOneColumnProperty(f);
            }
            //对列排序
            Collections.sort(columnPropertyList);
            if (head == null || head.size() == 0) {
                for (ExcelColumnProperty excelColumnProperty : columnPropertyList) {
                    headList.add(excelColumnProperty.getHead());
                }
                this.head = headList;
            }
        }
    }

有时会有一种需求，即根据用户输入的不同，输出字段有略微差异的表。比如，导出某公司所有员工的表时，根据操作用户的权限，部分员工（如人力资源部门的员工）可以看到工资字段，而其他员工看不到。这时，使用继承，将所有员工都可以看到的字段放到父类里面去，将特殊员工才能看到的字段放到子类里面，根据操作对象返回不同的类，是解决这一问题的一种方法。因此，获取父类继承下来的字段在有些时候是比较有用的。使用commons包里面的反射函数，可以很方便地获取到从父类继承下来的字段

怎么合并单元格呢？

按照模型读取，都是从第一行开始读取，而不是按照Sheet传入参数进行读取，导致模型转换失败。

AnalysisEventListener 这个类使用泛型 AnalysisEventListener之后就不做处理了, invoke的参数Object回来是个集合

日志原生日志太少、
Debug日志没有，INFO没有，ERROR没有；
请问是否考虑 增加各类型日志输出

单元格内容包含:<>时，读取结果混乱

为什么这个解析成了这样？

我看这里有一句代码：

写Excel 每行数据是List无表头 中
应该调用writer.write0()方法，文档中使用了writer.write()方法。

SaxAnalyserV07.java 行，代码行170左右；
if (qName.toLowerCase(Locale.US).equals("sheet")) {
String name = null;
int id = 0;
for (int i = 0; i < attrs.getLength(); i++) {
if (attrs.getLocalName(i).toLowerCase(Locale.US).equals("name")) {// 此处LocalName.执行失效、getQName 生效；
name = attrs.getValue(i);
} else if (attrs.getLocalName(i).toLowerCase(Locale.US).equals("r:id")) {
id = Integer.parseInt(attrs.getValue(i).replaceAll("rId", ""));
try {
InputStream inputStream = new FileInputStream(XMLTempFile.getSheetFilePath(path, id));
sheetSourceList.add(new SheetSource(id, name, inputStream));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
}
}

下面代码的是要把list的倒叙排？？？如果不是要倒叙排是不是直接用链表就可以了。。。。

`
private class SheetSource implements Comparable {

    private int id;

    private String sheetName;

    private InputStream inputStream;

    public SheetSource(int id, String sheetName, InputStream inputStream) {
        this.id = id;
        this.sheetName = sheetName;
        this.inputStream = inputStream;
    }

    public String getSheetName() {
        return sheetName;
    }

    public void setSheetName(String sheetName) {
        this.sheetName = sheetName;
    }

    public InputStream getInputStream() {
        return inputStream;
    }

    public void setInputStream(InputStream inputStream) {
        this.inputStream = inputStream;
    }

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public int compareTo(SheetSource o) {
        if (o.id == this.id) {
            return 0;
        } else if (o.id > this.id) {
            return 1;
        } else {
            return -1;
        }
    }
}

使用poi的sax读取10W条数据秒级读完,使用easyexcel需要半小时,超级慢

用easyexcel导出的excel，再导入时报错：java.io.FileNotFoundException: D:\apache-tomcat-8.0.36\temp\easyexcel-4014190947417093486\xl\worksheets\sheet3.xml (系统找不到指定的文件。)
明明应该是sheet1的，这里的workbook.xml里面的sheet中的r:id会变成rId3

@ExcelProperty(value = "处理时间", index = 13,format = "yyyy-MM-dd HH:mm:ss")

ExcelReader调用finish时，删除临时文件成功，临时目录也应该需要删除吧，
具体代码如下

com.alibaba.excel.util.FileUtil

`
public static void deletefile(String delpath) {

    File file = new File(delpath);

    if (!file.isDirectory()) {

        file.delete();

    } else if (file.isDirectory()) {

        String[] filelist = file.list();

        for (int i = 0; i < filelist.length; i++) {

            File delfile = new File(delpath + File.separator + filelist[i]);

            if (!delfile.isDirectory()) {

                delfile.delete();

            } else if (delfile.isDirectory()) {

                deletefile(delpath + File.separator + filelist[i]);

            }

        }
     // 这里是否需要加一个
        file.delete
    }

}

首先感谢作者开源此工具。用起来确实很方便
模板中这样写没问题

    @ExcelProperty(value = {"协议支付","本期新增客户数量"},index = 1)
    private String p2;

    @ExcelProperty(value = {"协议支付","本期减少客户数量"},index = 2)
    private int p3;

    @ExcelProperty(value = {"协议支付","本期净增客户数量"},index = 3)
    private long p4;

    @ExcelProperty(value = {"协议支付","累计签约客户数量"},index = 4)
    private String p5;

    @ExcelProperty(value = {"商业委托支付","上期末存量客户数量1"},index = 5)
    private String p6;

    @ExcelProperty(value = {"商业委托支付","本期新增客户数量1"},index = 6)
    private String p7;

    @ExcelProperty(value = {"商业委托支付","本期减少客户数量1"},index = 7)
    private String p8;

    @ExcelProperty(value = {"商业委托支付","本期净增客户数量1"},index = 8)
    private String p9;

    @ExcelProperty(value = {"商业委托支付","累计签约客户数量1"},index = 9)
    private String p10;

但是这样写就报错

    @ExcelProperty(value = {"协议支付","本期新增客户数量"},index = 1)
    private String p2;

    @ExcelProperty(value = {"协议支付","本期减少客户数量"},index = 2)

    @ExcelProperty(value = {"协议支付","本期净增客户数量"},index = 3)
    private long p4;

    @ExcelProperty(value = {"协议支付","累计签约客户数量"},index = 4)
    private String p5;

    @ExcelProperty(value = {"商业委托支付","上期末存量客户数量"},index = 5)
    private String p6;

    @ExcelProperty(value = {"商业委托支付","本期新增客户数量"},index = 6)
    private String p7;

    @ExcelProperty(value = {"商业委托支付","本期减少客户数量"},index = 7)
    private String p8;

    @ExcelProperty(value = {"商业委托支付","本期净增客户数量"},index = 8)
    private String p9;

    @ExcelProperty(value = {"商业委托支付","累计签约客户数量"},index = 9)
    private String p10;

如题，如何给某个cell添加超链接？
poi是可以的，如下代码所示：
cell = row.createCell(colNumber)。 cell.setCellType(HSSFCell.CELL_TYPE_FORMULA); cell.setCellFormula("HYPERLINK(\"" + "Http://www.google.ca"+ "\",\"" + "Google Canada"+ "\")"); 或cell.setCellFormula("HYPERLINK(\"[workbook.xls]'sheet2'!A1\",\"homepage\")"); //HYPERLINK("#明细!A1","homepage")
我查看了一下源代码，好像没有把这个功能带过来，也就是没有实现。

采用 @ExcelProperty(value = {"一级表头","二级表头"})用于解决不确切知道excel第几列和该字段映射，位置不固定，但表头的内容知道的情况。

数据使用mac版本的office新建的excel，读取有问题，拿到windows系统也读取有问题。用windows系统创建的excel，在mac上读取无问题。

导入数据.xlsx

首先感谢作者开源此工具。用起来确实很方便
刚编写的Issues不小心点了关闭，重新发下。
模板中这样写没问题

    @ExcelProperty(value = {"协议支付","本期新增客户数量"},index = 1)
    private String p2;

    @ExcelProperty(value = {"协议支付","本期减少客户数量"},index = 2)
    private int p3;

    @ExcelProperty(value = {"协议支付","本期净增客户数量"},index = 3)
    private long p4;

    @ExcelProperty(value = {"协议支付","累计签约客户数量"},index = 4)
    private String p5;

    @ExcelProperty(value = {"商业委托支付","上期末存量客户数量1"},index = 5)
    private String p6;

    @ExcelProperty(value = {"商业委托支付","本期新增客户数量1"},index = 6)
    private String p7;

    @ExcelProperty(value = {"商业委托支付","本期减少客户数量1"},index = 7)
    private String p8;

    @ExcelProperty(value = {"商业委托支付","本期净增客户数量1"},index = 8)
    private String p9;

    @ExcelProperty(value = {"商业委托支付","累计签约客户数量1"},index = 9)
    private String p10;

但是这样写就报错

    @ExcelProperty(value = {"协议支付","本期新增客户数量"},index = 1)
    private String p2;

    @ExcelProperty(value = {"协议支付","本期减少客户数量"},index = 2)
    private int p3;

    @ExcelProperty(value = {"协议支付","本期净增客户数量"},index = 3)
    private long p4;

    @ExcelProperty(value = {"协议支付","累计签约客户数量"},index = 4)
    private String p5;

    @ExcelProperty(value = {"商业委托支付","上期末存量客户数量"},index = 5)
    private String p6;

    @ExcelProperty(value = {"商业委托支付","本期新增客户数量"},index = 6)
    private String p7;

    @ExcelProperty(value = {"商业委托支付","本期减少客户数量"},index = 7)
    private String p8;

    @ExcelProperty(value = {"商业委托支付","本期净增客户数量"},index = 8)
    private String p9;

    @ExcelProperty(value = {"商业委托支付","累计签约客户数量"},index = 9)
    private String p10;

如果必须不能重复，是否可以考虑引入Alias,毕竟名字重复列很正常，或者说我用的不对，烦请说明。

项目里面 是 查询数据库 获取到数据后，写入\生成excel
