Java实现word转HTML

清疚 2023-06-18 13:57 22阅读 0赞

Java word转html主要是为了word的在线浏览。不过转换可用性不是很好。我们先开始开发吧

**第一步：引用Maven**

<dependency>
    			<groupId>org.apache.poi</groupId>
    			<artifactId>poi-scratchpad</artifactId>
    			<version>3.14</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.apache.poi</groupId>
    			<artifactId>poi-ooxml</artifactId>
    			<version>3.14</version>
    		</dependency>
    
    		<dependency>
    			<groupId>fr.opensagres.xdocreport</groupId>
    			<artifactId>xdocreport</artifactId>
    			<version>1.0.6</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.apache.poi</groupId>
    			<artifactId>poi-ooxml-schemas</artifactId>
    			<version>3.14</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.apache.poi</groupId>
    			<artifactId>ooxml-schemas</artifactId>
    			<version>1.3</version>
    		</dependency>
    
    		<dependency>
    			<groupId>org.jsoup</groupId>
    			<artifactId>jsoup</artifactId>
    			<version>1.11.3</version>
    		</dependency>

**第二步：java实现代码**

            //1.2) 加载word文档生成 XWPFDocument对象
            InputStream in = new FileInputStream( wordFile );
            XWPFDocument document = new XWPFDocument( in );
            //1.3) 解析 XHTML配置 (这里设置IURIResolver来设置图片存放的目录)
            final String imagePath = wordPath + "image" ;
            File imgFolder = new File( imagePath );
            XHTMLOptions options = XHTMLOptions.create();
            options.setExtractor(new FileImageExtractor(imgFolder));

            options.setIgnoreStylesIfUnused(false);
            options.setFragment(true);
            //1.4) 将 XWPFDocument转换成XHTML
            // 生成html文件上级文件夹
            File folder = new File(htmlPath);

            XHTMLConverter.getInstance().convert(document, out, options);
            return htmlFile.getAbsolutePath();
        }
    
        public static void main(String[] args) {
            try {
                //Word2003ToHtml("E:\\templates", "2019-11-26", ".doc", "E://templates/");
                WordAutoToHtml( new File("E:\\templates\\OnLineWord.doc") , "image_" , "image/");
                //WordAutoToHtml( new File("E:\\templates\\OnLineWord.docx") , "image_" , "image/");
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
    
    }

**第三步：使用结果**

2007版本：Word文档样式

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lleGlhb21vZGVtbw_size_16_color_FFFFFF_t_70][]

实际转换结果为：图片的居中，字体等信息自动换行效果不理想。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3lleGlhb21vZGVtbw_size_16_color_FFFFFF_t_70 1][]

2003版本的Word文档也有上述问题，大家使用此技术时请注意此问题。
