poi根据模板导出word文档

POI结构与常用类

Apache POI是Apache软件基金会的开源项目，POI提供API给Java程序对Microsoft Office格式档案读和写的功能。 .NET的开发人员则可以利用NPOI (POI for .NET) 来存取 Microsoft Office文档的功能。

包名称说明

• HSSF提供读写Microsoft Excel XLS格式档案的功能。
• XSSF提供读写Microsoft Excel OOXML XLSX格式档案的功能。
• HWPF提供读写Microsoft Word DOC格式档案的功能。
• HSLF提供读写Microsoft PowerPoint格式档案的功能。
• HDGF提供读Microsoft Visio格式档案的功能。
• HPBF提供读Microsoft Publisher格式档案的功能。
• HSMF提供读Microsoft Outlook格式档案的功能。

测试例子

测试模板：

测试代码：

@Test
    public void docxExportTest() throws IOException {
        InputStream is = null;
        FileOutputStream fos = null;
        try {
            //获取docx解析对象
            is = new FileInputStream("F:\\document\\咨询服务合同.docx");
            XWPFDocument document = new XWPFDocument(is);

            //组装参数
            File seal = new File("F:\\imgtest\\1.jpg");
            Map<String, Object> sealMap = new HashMap<String, Object>();
            sealMap.put("width", 50);
            sealMap.put("height", 50);
            sealMap.put("type", "jpg");
            sealMap.put("content", new FileInputStream(seal));

            Map<String, Object> contentMap = new HashMap<>();
            contentMap.put("part_a", "张三");
            contentMap.put("address_a", "青岛市市南区动漫产业园E座");
            contentMap.put("legal_person_a", "李四");
            contentMap.put("seal", sealMap);

            //解析替换段落文本对象
            XWPFUtil.changeParagraph(document, contentMap);

            //生成新的word文档
            SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
            String fileName = "咨询服务合同" + sdf.format(new Date()) + ".docx";
            File file = new File("F://" + fileName);
            fos = new FileOutputStream(file);
            document.write(fos);

        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (is != null) {
                is.close();
            }
            if (fos != null) {
                fos.close();
            }
        }
    }

注意事项

1.实际开发过程中，模板通常存放在项目工程中，获取模板的代码如下：

String tempPath = "static/exportTemplates/咨询服务合同.docx";
ClassPathResource resource = new ClassPathResource(tempPath);
InputStream is = resource.getInputStream();
XWPFDocument document = new XWPFDocument(is);

2.导出文件时如果报错：Failed to read zip entry source，是因为打包编译将文件解压缩导致出问题，解决办法为在pom文件中配置nonFilteredFileExtension：

<plugin>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.6</version>
                <configuration>
                    <delimiters>
                        <delimiter>@</delimiter>
                        <delimiter>${*}</delimiter>
                    </delimiters>
                    <useDefaultDelimiters>false</useDefaultDelimiters>
                    <encoding>UTF-8</encoding><!-- 指定编码格式，否则在DOS下运行mvn命令时当发生文件资源copy时将使用系统默认使用GBK编码 -->
                    <nonFilteredFileExtensions>
                        <nonFilteredFileExtension>bar</nonFilteredFileExtension>
                        <nonFilteredFileExtension>zip</nonFilteredFileExtension>
                        <nonFilteredFileExtension>txt</nonFilteredFileExtension>
                        <nonFilteredFileExtension>pdf</nonFilteredFileExtension>
                        <nonFilteredFileExtension>ttf</nonFilteredFileExtension>
                        <nonFilteredFileExtension>xlsx</nonFilteredFileExtension>
                        <nonFilteredFileExtension>xls</nonFilteredFileExtension>
                        <nonFilteredFileExtension>docx</nonFilteredFileExtension>
                        <nonFilteredFileExtension>doc</nonFilteredFileExtension>
                    </nonFilteredFileExtensions>
                </configuration>
            </plugin>

 3.所有导出参数必须转换成string类型后才能导出，否则替换不了。
