Detailed description of jsp export doc file instances by format

Principle:The doc file can be saved as an xml file. The xml file uses a string to represent the representation of the doc file, we only need to use Java to replace the content to be filled and then download it to the customer.

1. Fill in the data according to your document.
2. Save the document as an xml file, edit the xml file, and replace the filled content with a certain format. For example, replace the name with three replicas $ {name}
3. Read the file and replace $ {name} in the file with a real name.
4. download.

Next, let's look at the Code:

First, the conversion class

package com.my.util;import java.io.BufferedReader;import java.io.ByteArrayInputStream;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileReader;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.UnsupportedEncodingException;import java.util.Iterator;import java.util.Map;public class DowloadDocByTemplate {  public InputStream dowload(String templatePath,Map map) throws IOException{        File file = new File(templatePath);    StringBuffer sb = new StringBuffer();      BufferedReader br;        br = new BufferedReader(new InputStreamReader(new FileInputStream(file),"UTF-8"));        String s;        while ((s = br.readLine()) != null) {          sb.append(s);                  }        br.close();         s = sb.toString();          Iterator<String> keys = map.keySet().iterator();          while(keys.hasNext()) {            String key = (String) keys.next();            s=s.replace(key, (String) map.get(key));         }          return new ByteArrayInputStream(s.getBytes("UTF-8"));  }}  

Then there is action:

/*** Check the download permission * @ return */public String downLoadcheck () {return SUCCESS;} public String getTargetFileName () {return "zengguoqg.doc";} public InputStream getInputStream () {// ExportToWordUtil etw = new ExportToWordUtil (); StringBuffer carnumber = new StringBuffer ("<w: tr w: rsidR = '000000'> <w: trPr> <w: trHeight w: hRule = 'extract' w: val = '000000'/> </w: trPr> "); String s1 =" <w: tc> <w: tcPr> <w: tcW w: w = \ "236 \" w: type = \ "dxa \"/> </w: tcPr> <w: p w: rsidR = \ "00000000 \" w: rsidRDefault = \ "009F38EE \"> "+" <w: pPr> <w: rPr> <w: rFonts w: hint = \ "eastAsia \"/> </w: rPr> </w: pPr> <w: r> "+" <w: rPr> <w: rFonts w: hint = \ "eastAsia \"/> </w: rPr> <w: t> "; String number =" 450981199202073518 "; char [] ch = number. toCharArray (); for (int I = 0; I <ch. length; I ++) {carnumber. append (s1 ). append (ch [I]). append ("</w: t> </w: r> </w: p> </w: tc>");} carnumber. append ("</w: tr>"); Map <String, String> map = new HashMap (); map. put ("$ {name}", "Zeng Qiang"); map. put ("$ {sex}", "male"); map. put ("$ {writeDate}", "2014.1.2"); map. put ("$ {cardNumber}", "1100106"); map. put ("$ {personNumber}", carnumber. toString (); map. put ("$ {birthday}", "2014.1.2"); map. put ("$ {Education}", "Undergraduate"); map. put ("$ {marride}", "Unmarried"); map. put ("$ {comeFrom}", "Guangxi"); map. put ("$ {nation}", "Han"); map. put ("$ {ResidenceAddress}", "Guangxi"); map. put ("$ {PostalCode}", "543002"); map. put ("$ {QQ}", "1104566175"); map. put ("$ {job}", "software engineer"); map. put ("$ {politicalStatus}", "political outlook"); map. put ("$ {GraduateSchool}", ""); map. put ("$ {professional}", "Software Engineering"); map. put ("$ {beginWorkTime}", "2014.1.2"); map. put ("$ {bankCarNumber}", "622709"); map. put ("$ {emergencyContactPerson}", "Zeng Qiang"); map. put ("$ {relationship}", "Students"); map. put ("$ {ummoveTelephone}", "0774133"); map. put ("$ {mobilePhone}", "1350335"); map. put ("$ {adreess}", "Guangxi"); map. put ("$ {mainExperience}", "No job"); map. put ("$ {favoriteAndGoodAt}", "basketball"); String path = ServletActionContext. getServletContext (). getRealPath ("/fileTemplate/renyuandengjibiao2.xml"); System. out. println (path); // return etw. export (path, "test. xml ", map," out.doc "); try {return new DowloadDocByTemplate (). dowload (path, map);} catch (IOException e) {// TODO Auto-generated catch block e. printStackTrace (); return null ;}}}

Finally, download the Strut Configuration:

<Package name = "dowload" extends = "struts-default"> <action name = "dowload" class = "zhaopingAction" method = "downLoadcheck"> <result name = "success" type = "stream"> <param name = "contentType"> application/ZIP </param> <! -- The default value is text/plain --> <param name = "inputName"> inputStream </param> <param name = "contentDisposition"> filename = "$ {targetFileName}" </param & gt; <param name = "bufferSize"> 4096 </param> <! -- Buffer size during output --> </result> </action>

That's all. Xml files are stored in WebRoot/fileTemplate/renyuandengjibiao2.xml.
