Java使用poi生成word文档的简单实例

生成的效果如下：

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：
