第一、导入依赖
<!-- docx 数据填充生成 doc文件  这个是主要 -->
<!-- POI -->
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi</artifactId>
    <version>4.1.2</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml</artifactId>
    <version>4.1.2</version>
</dependency>
<dependency>
    <groupId>org.apache.poi</groupId>
    <artifactId>poi-ooxml-schemas</artifactId>
    <version>4.1.2</version>
</dependency>

<!-- poi-tl -->
<dependency>
    <groupId>com.deepoove</groupId>
    <artifactId>poi-tl</artifactId>
    <version>1.10.0</version>
</dependency>

第二、配置maven打包，过滤掉word文件，不加以编码，否则会报错

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.1.0</version>
    <configuration>
        <encoding>UTF-8</encoding>
        <nonFilteredFileExtensions>
            <!-- Caused by: java.util.zip.ZipException: Unexpected record signature: 0X9
            应该是编译代码时，把excel模板文件也重新编码了，导致excem模板文件格式损坏
            需要过滤掉不需要编码的文件：过滤后缀为.xlsx或者.xls,docx后者doc的所有文件，不对其进行统一编码-->
            <nonFilteredFileExtension>xlsx</nonFilteredFileExtension>
            <nonFilteredFileExtension>xls</nonFilteredFileExtension>
            <nonFilteredFileExtension>docx</nonFilteredFileExtension>
            <nonFilteredFileExtension>doc</nonFilteredFileExtension>
            <nonFilteredFileExtension>pptx</nonFilteredFileExtension>
            <nonFilteredFileExtension>ppt</nonFilteredFileExtension>
        </nonFilteredFileExtensions>
    </configuration>
</plugin>

第三、编写测试代码

@GetMapping("/filld")
@ApiOperation("测试word代码填充")
public void zipDdownload2(HttpServletRequest request, HttpServletResponse response) throws IOException {
    Map<String, Object> params = new HashMap<>();
    params.put("legalCode","dddd");
    params.put("channel","数智xxx");
    Resource resource = new ClassPathResource("templates_report/2.docx");
    File file = resource.getFile();
    //创建输出流
    OutputStream os = new FileOutputStream("template1_out.docx");
    //最终编译渲染并输出
    XWPFTemplate.compile(file).render(params).writeAndClose(os);
    System.out.println("输出完毕");
}
