poi插件操作office文档

1、poi-tl
这个插件可用于导入导出word文档，简单易用(附文档地址:http://deepoove.com/poi-tl/#example-article)
使用步骤：

1、添加maven依赖

    com.deepoove
    poi-tl
    1.3.1

2、使用示例
package com.ph.admin.util;

import java.io.*;
import java.util.*;
import java.util.Map.Entry;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import com.deepoove.poi.data.TableRenderData;
import com.deepoove.poi.data.TextRenderData;
import com.deepoove.poi.data.style.Style;
import com.deepoove.poi.render.RenderAPI;
import org.apache.commons.lang3.StringUtils;
import org.apache.poi.POIXMLProperties.CoreProperties;
import org.apache.poi.hwpf.HWPFDocument;
import org.apache.poi.hwpf.usermodel.Range;
import org.apache.poi.xwpf.extractor.XWPFWordExtractor;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
import org.apache.poi.xwpf.usermodel.XWPFTable;
import org.apache.poi.xwpf.usermodel.XWPFTableCell;
import org.apache.poi.xwpf.usermodel.XWPFTableRow;

import com.deepoove.poi.XWPFTemplate;
import com.deepoove.poi.data.PictureRenderData;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTSym;

/**

public class WriteWordUtil {

    /**
     * word占位用{{object}}比较完美可以填充图片
     * @param filePath
     * @param params
     * @param outFilePath
     * @return
     * @throws Exception
     */
    public static String templateWrite(String filePath, Map params,String outFilePath)throws Exception{
        XWPFTemplate template = XWPFTemplate.create(filePath);
        RenderAPI.render(template,params);
        FileOutputStream out = new FileOutputStream(outFilePath);
        template.write(out);
        out.flush();
        out.close();
        return "";
    }
    public static void main(String[] args) throws Exception {
        Map params = new HashMap();
        params.put("location", "上海");//  location对应word文档中的格式是{{location}}
        templateWrite("D:\\in.docx", params, "D:\\out.docx");
    }
}

2、jxls2
这个插件可以用来对Excel文件的导入和导出(附文档地址:http://jxls.sourceforge.net/)
使用步骤：

1、添加maven依赖

    org.jxls
    jxls-poi
    <version>1.0.13version>

      
          org.jxls
          jxls
          <version>2.4.6version>
      

    org.jxls
    jxls-jexcel
    <version>1.0.7version>

2、使用示例
package com.ph.admin.util.quartz;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

/**

public class JxlsUtils{

    public static void exportExcel(InputStream is, OutputStream os, Map model) throws IOException{
        Context context = PoiTransformer.createInitialContext();
        if (model != null) {
            for (String key : model.keySet()) {
                context.putVar(key, model.get(key));
            }
        }
        JxlsHelper jxlsHelper = JxlsHelper.getInstance();
        Transformer transformer  = jxlsHelper.createTransformer(is, os);
        //获得配置
        JexlExpressionEvaluator evaluator = (JexlExpressionEvaluator)transformer.getTransformationConfig().getExpressionEvaluator();
        //设置静默模式，不报警告
        //evaluator.getJexlEngine().setSilent(true);
        //函数强制，自定义功能
//        Map funcs = new HashMap();
//        funcs.put("utils", new JxlsUtils());    //添加自定义功能
//        evaluator.getJexlEngine().setFunctions(funcs);
        //必须要这个，否者表格函数统计会错乱
        jxlsHelper.setUseFastFormulaProcessor(false).processTemplate(context, transformer);
    }

    public static void exportExcel(File xls, File out, Map model) throws FileNotFoundException, IOException {
            exportExcel(new FileInputStream(xls), new FileOutputStream(out), model);
    }

    public static void exportExcel(String templatePath, OutputStream os, Map model) throws Exception {
        File template = getTemplate(templatePath);
        if(template != null){
            exportExcel(new FileInputStream(template), os, model);
        } else {
            throw new Exception("Excel 模板未找到。");
        }
    }

    //获取jxls模版文件
    public static File getTemplate(String path){
        File template = new File(path);
        if(template.exists()){
            return template;
        }
        return null;
    }

    // 日期格式化
    public String dateFmt(Date date, String fmt) {
        if (date == null) {
            return "";
        }
        try {
            SimpleDateFormat dateFmt = new SimpleDateFormat(fmt);
            return dateFmt.format(date);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return "";
    }

    // if判断
    public Object ifelse(boolean b, Object o1, Object o2) {
        return b ? o1 : o2;
    }

public static void main(String[] args) throws Exception {
        // 模板路径和输出流
        String templatePath = "d:\\in.xlsx";
        OutputStream os = new FileOutputStream("d:\\out.xlsx");
        // 定义一个Map，往里面放入要在模板中显示数据
        Map item = new HashMap();
        item.put("zqcode","11111"); //zqcode对应Excel里面的${zqcode}
        //调用之前写的工具类，传入模板路径，输出流，和装有数据Map
        exportExcel(templatePath, os, item);
        os.close();
        System.out.println("完成");
    }
