前几天在公安局做项目，要改一个execl，向其中增加字段。其中数量比较大，为了方便，就随便写个
import jxl.*;
import jxl.format.UnderlineStyle;
import jxl.format.UnderlineStyle;
import jxl.write.*;
import jxl.write.Number;
import jxl.write.Boolean;

import java.io.*;
import java.util.ArrayList;

public class d {
public d() {
}

public static void readExcel(String filePath, int x) {
try {
InputStream is = new FileInputStream(filePath);
Workbook rwb = Workbook.getWorkbook(is);
Sheet st = rwb.getSheet("Sheet1");
Cell c00 = null, c11 = null;
WritableWorkbook wwb = Workbook.createWorkbook((new File("d:/m.xls")), rwb);
//d盘m文件为新生成的文件
WritableSheet ws = wwb.getSheet("Sheet1");
String strc00 = null, strc11 = null;
ArrayList list = null;
WritableCell wc = null;
for (int i = 1; i < x; i++) {
c00 = st.getCell(1, i);
if (c00.getType() == CellType.LABEL) {
LabelCell labelc00 = (LabelCell) c00;
strc00 = labelc00.getString();
wc = ws.getWritableCell(2, i);

strc00 = c00.getContents();
//可以加各种条件
if (strc00.contains("刑事")) {
if (wc.getType() == CellType.LABEL) {
Label label = (Label) wc;
label.setString("刑侦");
}
} else if(strc00.contains("派出所")){
if (wc.getType() == CellType.LABEL) {
Label label = (Label) wc;
label.setString("派出所");
}
} else if(strc00.contains("巡警")||strc00.contains("巡逻")){
if (wc.getType() == CellType.LABEL) {
Label label = (Label) wc;
label.setString("交警");
}
}else if(strc00.contains("经济保卫")){
if (wc.getType() == CellType.LABEL) {
Label label = (Label) wc;
label.setString("经保");
}
}
c00 = null;
strc00 = null;
}
}
rwb.close();
wwb.write();
wwb.close();
rwb.close();
} catch (Exception e) {
e.printStackTrace();
}

}

// 测试
public static void main(String[] args) {
try {
// 读Excel
//将execl文件放入d盘中，比如要转化f文件 ，后面的数字为要修改的行数
d.readExcel("d:/f.xls", 7435);

} catch (Exception e) {
e.printStackTrace();
}
}
}
