写在前面:日常开发中,经常会碰到富文本使用场景,有些需求是必须导出到word中,所以我们来实现吧!

一、引入POM
<properties>
<poi.version>4.1.2</poi.version>
<hutool.version>4.6.10</hutool.version>
<guava.version>20.0</guava.version>
<commons-lang3.version>3.9</commons-lang3.version>
</properties>
<dependencies>
<dependency>
<groupId>com.google.guava</groupId>
<artifactId>guava</artifactId>
<version>{guava.version}</version> </dependency> <dependency> <groupId>org.apache.commons</groupId> <artifactId>commons-lang3</artifactId> <version>{commons-lang3.version}</version>
</dependency>
<dependency>
<groupId>cn.hutool</groupId>
<artifactId>hutool-all</artifactId>

</dependency>

二、Java测试类

import cn.hutool.core.io.FileUtil;
import com.deepoove.poi.XWPFTemplate;
import com.deepoove.poi.config.Configure;
import com.deepoove.poi.data.PictureRenderData;
import com.deepoove.poi.policy.PictureRenderPolicy;
import com.deepoove.poi.xwpf.NiceXWPFDocument;
import com.spire.doc.Document;
import com.spire.doc.DocumentObject;
import com.spire.doc.Section;
import com.spire.doc.FileFormat;
import org.apache.commons.io.IOUtils;
import org.apache.commons.lang3.StringUtils;
import org.ddr.poi.html.HtmlRenderPolicy;

import java.io.;
import java.util.
;

/**

    public class Java2Word {

    public static void main(String[] args) throws IOException {
    // html渲染插件
    HtmlRenderPolicy htmlRenderPolicy = new HtmlRenderPolicy();
    // 第一个案例
    Configure configure = Configure.builder()
    // 注册html解析插件
    .bind("content", htmlRenderPolicy)
    // .bind("content2", htmlRenderPolicy)
    .build();
    // 映射数据Map
    Map<String, Object> data = new HashMap<>();
    data.put("title", "我是一个案例名称1");
    data.put("keywords", "我是一个案例keywords");
    data.put("cty", "我是一个案例cty");
    data.put("content", readFile("/demo1.html"));
    // 读取模板文件,并渲染数据
    XWPFTemplate template = XWPFTemplate.compile(getResourceInputStream("/html2wordtemplate.docx"), configure).render(data);
    // 写入文件
    template.writeToFile("demo1.docx");
    template.close();

     // 第二个案例
     Configure configure1 = Configure.builder()
             .bind("content", htmlRenderPolicy)
             .build();
     Map<String, Object> data1 = new HashMap<>();
     data1.put("title", "我是一个案例名称2");
     data1.put("keywords", "我是一个案例keywords2");
     data1.put("cty", "我是一个案例分类2");
     data1.put("content", readFile("/demo2.html"));
     XWPFTemplate template1 = XWPFTemplate.compile(getResourceInputStream("/html2wordtemplate.docx"), configure1).render(data1);
     template1.writeToFile("demo2.docx");
     template1.close();
    
     // 合并word
     //加载需要合并的两个文档
     Document doc1 = new Document("demo1.docx");
     Document doc2 = new Document("demo2.docx");
     //获取文档1的最后一节
     Section lastsec = doc1.getLastSection();
     //遍历文档2的所有段落内容,添加到文档1
     for (Section section : (Iterable<Section>) doc2.getSections()) {
         for (DocumentObject obj : (Iterable<DocumentObject>) section.getBody().getChildObjects()) {
             lastsec.getBody().getChildObjects().add(obj.deepClone());
         }
     }
     //保存合并后的文档
     doc1.saveToFile("ALL-Word.docx", FileFormat.Docx);
    

    }

/**
* 读取文件内容
*
* @param resourceFile 文件路径
* @return 文件内容
* @throws IOException IO异常
* import org.apache.commons.io.IOUtils;
*/
public static String readFile(String resourceFile) throws IOException {
try (InputStream inputStream = FileReader.class.getResourceAsStream(resourceFile)) {
return IOUtils.toString(inputStream, StandardCharsets.UTF_8);
}
}

}

三、运行结果

注意:poi-tl-ext 0.3.3的版本,在实际用的过程中,对于如下html解析有误,比如行距问题,切换到到0.3.18解决问题。
