二:java实现将pdf转换为html

 1  /* 2      * txt文档转html 3        filepath:txt原文件路径 4        htmlposition:转化后生成的html路径 5     */ 6     public static void txttohtml(string filepath, string htmlposition) { 7         try { 8             //string encoding = gbk; 9             file file = new file(filepath);10             if (file.isfile() && file.exists()) { // 判断文件是否存在11                 inputstreamreader read = new inputstreamreader(new fileinputstream(file), gbk);12                 // 考虑到编码格式13                 bufferedreader bufferedreader = new bufferedreader(read);14                 // 写文件15                 fileoutputstream fos = new fileoutputstream(new file(htmlposition));16                 outputstreamwriter osw = new outputstreamwriter(fos, gbk);17                 bufferedwriter bw = new bufferedwriter(osw);18                 string linetxt = null;19                 while ((linetxt = bufferedreader.readline()) != null) {20                     bw.write(   +linetxt + </br>);21                 }22                 bw.close();23                 osw.close();24                 fos.close();25                 read.close();26             } else {27                 system.out.println(找不到指定的文件);28             }29         } catch (exception e) {30             system.out.println(读取文件内容出错);31             e.printstacktrace();32         }33     }
以上就是java实现word/pdf/txt转html的方法的详细内容。
