POI operation word template replaces data and exports word

One 、 Preface
poi operation word Template replacement data , It's simple , Not many algorithms are involved . I will provide poi Of jar package . The core idea is to word The part that needs to be replaced is written as a keyword , In operation word When , Replace with the data we filled in according to the keyword .
Two 、poi download
WeChat official account search ： The small white XBIT
Reply key ：poi, You can download .
3、 ... and 、 Realization
1、 take word The template is placed in a fixed path, such as ：D:\poi\inpoi\ Credit reporting ****.docx
2、 Match the data you want to replace with keywords to replace . adopt java Of Map The structure is similar to json Data format , The acquired data put go in . Here we need to pay attention to ,map Of key It must be with word The template of key identical , To replace . Another thing to note is , If the replacement is not successful , Need to put word Of key Rewrite it in your notebook , Copy and paste to word That's all right. .
3、 Core code
（1） Send the data from the front end , Put in map in
Key structures map Perform data replacement , The tool class for a while needs to use map

/*
	 *  Handle the ID card information of the borrower and the guarantor 
	 */
	@RequestMapping("jkr")
	@ResponseBody
	public JSONObject test(@RequestParam("name") String name,@RequestParam("sex") String sex,@RequestParam("idnum") 
	String idnum,@RequestParam("add") String add,@RequestParam("tel") String tel,@RequestParam("type") String type,
	HttpServletRequest request) {
		/*
		 *  The borrower ===1   map1
		 *  Borrower's spouse ===2  map2
		 *  guarantor 1===3    map3
		 *  guarantor 1 spouse ===4   map4
		 *  guarantor 2===5   map5
		 *  guarantor 2 spouse ===6   map6
		 *  guarantor 3===7  map7
		 *  guarantor 3 spouse ===8   map8
		 */
		if(type.equals(" The borrower ")) {
			request.getSession().setAttribute("type1", type);
			// newly build map1
			Map<String, String> map1=new HashMap<String, String>();
			map1.put("name1", name);
			map1.put("sex1", sex);
			map1.put("idnum1", idnum);
			map1.put("add1", add);
			map1.put("tel1", tel);
			// Put the borrower's information into session in 
			request.getSession().setAttribute("jkr", map1);
			//System.out.println(type+map1);
		}

（2） Replace

 // File path 　
String srcPath = "D:\\poi\\inpoi\\ Credit reporting \\****.docx";
// New file path 
 String destPath = "D:\\poi\\outpoi\\****.doc";
 wordUtils word=new wordUtils();
 // After finishing word transformation 
 String status=word.writer(srcPath, destPath, combineResultMap);

wordUtils It's the realization of word Tool class for text substitution
The specific code is as follows

public class wordUtils {
	
	public String allwrite(String inputSrc, String outSrc, Map<String,String> map) {
		

        try {
        	// Judge whether the file exists 
			File file = new File(inputSrc);
			if(!file.exists()){
				  return "fail";
			}else {

	            // obtain .docx File extractor  
	            XWPFDocument doc = new XWPFDocument(POIXMLDocument.openPackage(inputSrc));
	            /**
	             *  Replace the text specified in the paragraph 
	             */
	            for(XWPFParagraph p : doc.getParagraphs()){
	                List<XWPFRun> runs = p.getRuns();
	                if(runs != null){
	                    for(XWPFRun r : runs){
	                        // Text to replace 
	                        String text = r.getText(0);
	                        // Replace specified text 
	                        for(String key : map.keySet()){
	                            if(text != null && text.equals(key)){
	                                // Pay attention when replacing ,setText There are two parameters 
	                                // The first is the replacement text , The second is where to start the replacement 
	                                //0 Yes, replace all , If not set, the default is from the original text 
	                                // Append at the end 
	                                r.setText(map.get(key),0);
	                            }
	                        }
	                    }
	                }
	            }

	                        // Without this step, the text cannot be replaced 
	                        for(XWPFParagraph p : cell.getParagraphs()){
