标签：null   tab   int start   sql   规范   lis   索引   lex   _for   

在ExcelUtil.java中修改函数fillExcelData，判断是否为字段规范表的导出。

public void fillExcelData(int index, Row row)
{
    int startNo = index * sheetSize;
    int endNo = Math.min(startNo + sheetSize, list.size());
    Integer iRow=0;
    Integer iColumn =0;
    String cellString="";
    for (int i = startNo; i < endNo; i++)
    {
        row = sheet.createRow(i + 1 - startNo);
        // 得到导出对象.
        T vo = (T) list.get(i);
        int column = 0;
        for (Object[] os : fields)
        {
            Field field = (Field) os[0];
            Excel excel = (Excel) os[1];
            // 设置实体类私有属性可访问
            field.setAccessible(true);
            this.addCell(excel, row, vo, field, column++);
            System.out.println("row:"+row+" column:"+column+" vo:"+vo.toString()+" field:"+field.toString());
        }

        // 如果是字段规范表导出，自动增加生成数据库SQL的语句
        if(this.sheetName.equals("fieldStandard")){
            // 创建cell
            Cell cell = null;
            iRow = i+2;
            iColumn = column+4;
            cell = row.createCell(iColumn);

            if(i==endNo-1){
                cellString="=\"`\"&B"+iRow+"&\"` \"&E"+iRow+"&IF(TRIM(F"+iRow
                        +")<>\"\",\"(\" & F"+iRow+"&\") \",\"\")&IF(ISNUMBER(FIND(\"无符号\",H"+iRow
                        +")),\" UNSIGNED \",\" \")&IF(TRIM(J"+iRow
                        +")=\"不允许\",\"NOT NULL \",\"\")&IF(TRIM(K"+iRow
                        +")<>\"\",\"DEFAULT \" & K"+iRow+",\"\")&IF(ISNUMBER(FIND(\"自增\",H"+iRow
                        +")),\"AUTO_INCREMENT\",\"\")&\" COMMENT ‘\"&C"+iRow+"&\"‘\"";
            }else{
                cellString ="=\"`\"&B"+iRow+"&\"` \"&E"+iRow+"&IF(TRIM(F"+iRow
                        +")<>\"\",\"(\" & F"+iRow+"&\") \",\"\")&IF(ISNUMBER(FIND(\"无符号\",H"+iRow
                        +")),\" UNSIGNED \",\" \")&IF(TRIM(J"+iRow
                        +")=\"不允许\",\"NOT NULL \",\"\")&IF(TRIM(K"+iRow
                        +")<>\"\",\"DEFAULT \" & K"+iRow+",\"\")&IF(ISNUMBER(FIND(\"自增\",H"+iRow
                        +")),\"AUTO_INCREMENT\",\"\")&\" COMMENT ‘\"&C"+iRow+"&\"‘,\"";
            }

            cell.setCellFormula(cellString);
            System.out.println("==============================="+i);
        }
    }
    // 如果是字段规范表导出，自动增加生成数据库SQL的语句
    if(this.sheetName.equals("fieldStandard")){
        Cell cell=null;
        row = sheet.getRow(0);
        cell = row.createCell(iColumn-4);
        cell.setCellValue("允许为空");
        cell.setCellStyle(styles.get("header"));
        cell = row.createCell(iColumn-3);
        cell.setCellValue("默认值");
        cell.setCellStyle(styles.get("header"));
        cell = row.createCell(iColumn-2);
        cell.setCellValue("索引");
        cell.setCellStyle(styles.get("header"));

        cell = row.createCell(iColumn-1);
        cell.setCellValue("此处输入表名,右侧自动获取SQL语句");

        cell = row.createCell(iColumn);
        cell.setCellFormula("=\"DROP TABLE IF EXISTS `\"&M1&\"`; CREATE TABLE `\"&M1&\"` (\"");

        row = sheet.createRow(iRow);
        cell = row.createCell(iColumn);
        cell.setCellFormula("=\") ENGINE=InnoDB DEFAULT CHARSET=utf8 ROW_FORMAT=DYNAMIC COMMENT=‘\"&M1&\"‘\"");
    }
