Java POI是一个用于处理Microsoft Office文件（如Word、Excel和PowerPoint）的API,它是一个开源库,允许Java开发者读取、创建和修改这些文档,本文给大集介绍了Java使用poi生成word文档的简单实例,感兴趣的朋友可以参考下

Java使用poi生成word文档的简单实例
 

用到的poi的简单的知识

新建一个word对象

//新建文件
XWPFDocument document = new XWPFDocument();

新建段落以及文字样式

//创建段落
XWPFParagraph paragraph = document.createParagraph();
paragraph.setAlignment(ParagraphAlignment.CENTER);
 
//创建标题
XWPFRun titleFun = paragraph.createRun();
titleFun.setText("个人信息表");
titleFun.setBold(true);
titleFun.setFontSize(25);
titleFun.setColor("000000");
titleFun.setFontFamily("宋体");
titleFun.addBreak();
titleFun.addBreak(); 换行

实例-生成一个简单word文档

新建一个maven项目
pom.xml 导入5.2.5的poi的依赖包

<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>5.2.5</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>5.2.5</version>
</dependency>

新建SimpleWord.java文件
文件内容如下：

package com.wumeng.wordexport;
 
import org.apache.poi.xwpf.usermodel.*;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.*;

        paragraph.setAlignment(ParagraphAlignment.CENTER);
 
        //创建标题
        XWPFRun titleFun = paragraph.createRun();
        titleFun.setText("个人信息表");
        titleFun.setBold(true);
        titleFun.setFontSize(25);
        titleFun.setColor("000000");
        titleFun.setFontFamily("宋体");

运行，就可以看到效果了!!
