JAVA通过EasyPoi根据模板导出word文档

1、引入依赖

备注：如果没有jar包冲突,可以忽略jar排重(<exclusions>标签内内容)

 <dependency>
            <groupId>cn.afterturn</groupId>
            <artifactId>easypoi-base</artifactId>
            <version>4.3.0</version>
            <exclusions>
                <exclusion>
                    <artifactId>poi-ooxml-schemas</artifactId>
                    <groupId>org.apache.poi</groupId>
                </exclusion>
                <exclusion>
                    <artifactId>guava</artifactId>
                    <groupId>com.google.guava</groupId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>

            <artifactId>easypoi-annotation</artifactId>
            <version>4.3.0</version>
        </dependency>

2、word模板

3、具体代码

3.1controller层

@GetMapping(value = "/exportReportPreview")
public void exportReportPreview(HttpServletRequest request, HttpServletResponse response, @RequestParam String no) throws IOException {
    accidentService.exportReportPreview(request, response, no);
}

3.2实现类

@Override
public void exportReportPreview(HttpServletRequest request, HttpServletResponse response, String no) throws IOException {

   Accident accident = this.getAccidentByNo(no);

//★★★★★★★★模板存放在resources目录下,具体目录自己根据需求创建 //"template/docx/accident/首报.docx"
//fileSavePath  是临时目录(本地测试就是某个盘符下的路径,linux服务器就是具体路径)
    //word模板地址
    TemplateExportParams templateExportParams = new TemplateExportParams("template/docx/accident/首报.docx");
    String wordModelPath = templateExportParams.getTemplateUrl();
    //生成临时文件地址
    Map<String,Object> params = JSON.parseObject(JSON.toJSONString(accident), Map.class);
    ExportWordUtil.exportWord(wordModelPath,fileSavePath,accident.getTitle() + ".docx",params,request,response);

}

3.3工具类

@Slf4j
public class ExportWordUtil {
    /**
     * 导出word
     * <p>第一步生成替换后的word文件，只支持docx</p>
     * <p>第二步下载生成的文件</p>
     * <p>第三步删除生成的临时文件</p>
     * 模版变量中变量格式：{
   
   {foo}}
     * @param templatePath word模板地址
     * @param temDir 生成临时文件存放地址
     * @param fileName 文件名
     * @param params 替换的参数
     * @param request HttpServletRequest
     * @param response HttpServletResponse
