Java代码如何使用POI生成Word文档呢?

POI生成Word文档的实现思路

1.引入POI对应的包
2.定义XWPFDocument空对象
3.使用XWPFParagraph,XWPFTable等不同的对象生成不同的信息

package com.java265.controller;

    public static void main(String[] args)throws Exception {
        //Blank Document
        XWPFDocument document= new XWPFDocument();
 
        //Write the Document in file system
        FileOutputStream out = new FileOutputStream(new File("create_table.docx"));
 
 
        //添加标题
        XWPFParagraph titleParagraph = document.createParagraph();
        //设置段落居中
        titleParagraph.setAlignment(ParagraphAlignment.CENTER);
 
        XWPFRun titleParagraphRun = titleParagraph.createRun();
        titleParagraphRun.setText("Java PoI");
        titleParagraphRun.setColor("000000");
