【springmvc+mybatis项目实战】杰信商贸-29.购销合同技术难点分析

我们接下来要进行最复杂的一个打印，就是购销合同的打印---制式表单的打印，业界最复杂的报表打印。

a)分析技术难点：
1）插入图片，POI插入图片时，设定区域，自动缩放到这个区域中，图片要设置偏移量
HSSFPatriarch patriarch = sheet.createDrawingPatriarch(); //add picture
poiUtil.setPicture(wb, patriarch, path+"make/xlsprint/logo.jpg", curRow, 2, curRow+4, 2);

2）模板，对于购销合同它不能直接做模板。代码中不能做这个功能。Excel支持区域复制。但是目前POI不直接支持区域复制。（合并单元格在sheet对象中、图片、线等）（基于用户使用系统，以及POI不直接支持区域复制，所以它不能直接使用模板）
A.只是改变列宽
B.画一个sheet，利用poi支持sheet的复制，保留样式。

3）插入一根线，设置两个坐标，它直接连线，可以是直线，可以是斜线，可以设置偏移量
poiUtil.setLine(wb, patriarch, curRow, 2, curRow, 8); //draw line

4）合并单元格，特点：合并单元格的边线样式，它实际上是在合并前的单元格上设置的。特殊的地方：在单元格如果有样式，合并单元格的这几个格子都必须设置边线样式。
CellRangeAddress region = null;
region = new CellRangeAddress(curRow-1, curRow-1, 1, 3); //纵向合并单元格

不需要设置内容，只设置样式，补齐线。
for(int j=2;j<9;j++){
nCell = nRow.createCell(j);
nCell.setCellStyle(poiUtil.notehv10_BorderThin(wb, defaultFont10));
}

5）换行
curStyle.setWrapText(true);

6）设置人民币符号（前缀）
format.getFormat("\"￥\"#,###,###.00");

7）设置公式，乘法，合计公式
nCell.setCellType(HSSFCell.CELL_TYPE_FORMULA);
nCell.setCellFormula("F"+String.valueOf(curRow)+"*H"+String.valueOf(curRow));

8）实现审单人的人名等量空格替换，实现它后面的位置不变（工具类）
utilFuns.fixSpaceStr(contract.getCheckBy(),26)

9）单元格自适应（工具类）
float height = poiUtil.getCellAutoHeight(printMap.get("Request"), 12f); //自动高度

10）数据和业务分离
一页数据封装到一个map中，以业务字段名称定义KEY，以string定义内容
所有页面封装到一个arraylist。
Map<String,String> pageMap = null;
List<Map> pageList = new ArrayList(); //打印页



11）插入分页符
if(p>0){
sheet.setRowBreak(curRow++); //在第startRow行设置分页符
}

12）公用的工具类PoiUtil poiUtil = new PoiUtil();  样式，特殊内容封装

13）return format.getFormat("\"￥\"#,###,##0.00"); // 设置格式
0代表，这位值如果不为零，显示原来的内容，直接输出0
#代表，这位值如果存在，就直接显示，不存在，就不显示。

14）nCell.setCellType(HSSFCell.CELL_TYPE_NUMERIC);

购销合同最总打印样式:
