Java language combined with freemaker technology to export Word documents

Most of the time, you need to generate WORD Documents in the project. Java language and Freemaker technology are used to export Word documents. I think this method is good.

1. Check the code first.

The main program code is as follows:

Package com; import java. io. bufferedWriter; import java. io. file; import java. io. fileOutputStream; import java. io. IOException; import java. io. outputStreamWriter; import java. io. writer; import java. util. arrayList; import java. util. hashMap; import java. util. list; import java. util. map; import freemarker. template. configuration; import freemarker. template. template; import freemarker. template. templateException; public Class Word {private Configuration configuration = null; public Word () {configuration = new Configuration (); configuration. setDefaultEncoding ("UTF-8");} public void createDoc () {// Map dataMap = new HashMap (); getData (dataMap ); // set the method and path of the module. FreeMarker supports multiple template loading methods. It can be used to repeat servlet, classpath, database load, and // ftl file storage path configuration. setClassForTemplateLoading (this. getClass (), "/com/ftl"); Template t = null; try {// test. ftl is the template t = configuration to be loaded. getTemplate ("QQ. ftl "); t. setEncoding ("UTF-8");} catch (IOException e) {e. printStackTrace ();} // output File path and name File outFile = new File ("F:/2013/test.doc"); Writer out = null; try {out = new BufferedWriter (new OutputStreamWriter (new FileOutputStream (outFile), "UTF-8");} catch (Exception e1) {e1.printStackTrace ();} try {t. process (dataMap, out); out. close ();} catch (TemplateException e) {e. printStackTrace ();} catch (IOException e) {e. printStackTrace () ;}}/*** note that the Key value of the data stored in dataMap must correspond to the parameter in the template * @ param dataMap */private void getData (Map dataMap) {dataMap. put ("title", "Test"); dataMap. put ("nian", "2012"); dataMap. put ("danweiming", "Shaanxi"); List lists = new ArrayList (); WordBean w1 = new WordBean (); w1.setPaixu ("1 "); w1.setBiaoduan ("section 1"); WordBean w2 = new WordBean (); w2.setPaixu ("2"); w2.setBiaoduan ("section 2"); lists. add (w1); lists. add (w2); dataMap. put ("wordBeans", lists); dataMap. put ("paiming", "1"); dataMap. put ("biaoduan", "section 1");} public static void main (String [] args) {new Word (). createDoc ();}}

The JavaBean code is as follows:

package com;public class WordBean {public String paixu;public String biaoduan;public String getPaixu() {return paixu;}public void setPaixu(String paixu) {this.paixu = paixu;}public String getBiaoduan() {return biaoduan;}public void setBiaoduan(String biaoduan) {this.biaoduan = biaoduan;}}

The above code is easy to understand. The biggest question is how the QQ. ftl file came from?

2. Template File

(A): Save the edited wordtemplate.qq.doc as a QQ. xml file, create a freemaker file, QQ. ftl, and copy the QQ. xml file to the QQ. ftl file.

(B): Modify the ftl template file and replace the content to be replaced with tags such as $ {biaoduan.

(The ftl file is too long to be listed)

3. Run the program. The word file is generated to the specified location.

I personally think this generation method is much more convenient than jacob.
