主要的學習和踩坑
word模板1類型只有文字的只要用這種方式實現非常好,沒有圖片的word模板;特別注意的是支持.doc的模板
直接上代碼

3 .進行word模板轉word以及輸出前端下載實現代碼
//3.1替換的值 k,v map
HashMap<String, Object> contentMap = new HashMap<String, Object>();
contentMap.put("${date}", this.projectVO.getDate());
//3.2 模板路徑
String fileName = "book.doc";
String pathIn = GboatAppContext.getWebRootPath() +"download" + "/" + fileName;
//3.3 生成文件路徑 String exportFile = "進場交易確認書.docx";
String pathOut= GboatAppContext.getWebRootPath() + "download" + "/" + exportFile;
//執行
DocUtil.getBuild(pathIn , contentMap, exportFile);
//4這段代碼是 頁面直接彈出下載生成的文件
InputStream inStream = new FileInputStream(pathOut);
response.setHeader("Content-Type", "application/octet-stream");
// 設置response的編碼方式
response.setContentType("application/x-msdownload");
String headers = request.getHeader("User-Agent").toUpperCase();
if (headers.contains("MSIE") || headers.contains("TRIDENT") || headers.contains("EDGE")) {
exportFile = URLEncoder.encode(exportFile, "utf-8");
// IE下載文件名空格變+號問題
exportFile = exportFile.replace("+", "%20");
} else {
exportFile = new String(exportFile.getBytes("utf-8"), "ISO8859-1");
}
// 設置附加文件名
response.setHeader("Content-Disposition", "attachment;filename=" + exportFile);
byte[] b = new byte[512];
int len;
ServletOutputStream outputStream = response.getOutputStream();
while ((len = inStream.read(b)) > 0) {
outputStream.write(b, 0, len);
}
inStream.close();
// 將寫入到客戶端的內存的數據,刷新到磁盤
outputStream.flush();
outputStream.close();

4 word轉pdf,最後還是找了 使用libreoffice來進行轉pdf 這種方式
注,將 word文件利用libreoffice的第三方插件來轉換
1代碼工具類1
package glodon.govp.cy.utils;
import java.io.File;
import java.io.IOException;
/**
* 使用libreoffice來進行轉pdf
*/
public class LibreOffice {
public static boolean wordConverterToPdf(String docxPath) throws IOException {
File file = new File(docxPath);
String path = file.getParent();
try {
String osName = System.getProperty("os.name");
String command = "";
if (osName.contains("Windows")) {
command = "cmd /c soffice --convert-to pdf -outdir " + docxPath + " " + path;
} else {
command = "libreoffice --headless --invisible --convert-to pdf:writer_pdf_Export " + docxPath + " --outdir " + path;
System.out.println("命令----------------------"+command+"-----------------------------");
}
boolean result = CommandExecute.executeLibreOfficeCommand(command);
return result;
} catch (Exception e) {

3word調用libreoffice工具類實現的轉換的代碼
public static void main(String[] args) {
try {
LibreOffice.wordConverterToPdf("D:\\11.docx");
} catch (IOException e) {

}
}

String exportFile = projectName+"進場交易確認書.docx";//window的

exportFile = "進場交易確認書.docx";

HashMap<String, Object> contentMap = new HashMap<String, Object>();
contentMap.put("${date}", this.projectVO.getDate());
contentMap.put("${project}", this.projectVO.getProcurementAgenter()+"組織的"
+projectName+"（項目編號爲："+this.projectVO.getProjectCode()+"）已於"
+this.projectVO.getDate()+"在北京市朝陽區公共資源交易平臺完成交易。");
Map<String,Object> header = new HashMap<String, Object>();
header.put("width", 150);
header.put("height", 150);
header.put("type", "jpg");
header.put("content", WordUtils.inputStream2ByteArray(CyAdmissionConfirmationAction.class.getClassLoader().getResourceAsStream("static/gongzhang.jpg"), true));
contentMap.put("${picture}",header);
//生成word
WordUtils utils = new WordUtils();
utils.getWord(pathIn, contentMap, pathOut, response);
//word轉pdf
if (!osName.contains("Windows")) {
exportFile = "進場交易確認書.docx";
pathOut= GboatAppContext.getWebRootPath() + "download" + "/" + exportFile;
}
LibreOffice.wordConverterToPdf(pathOut);
//輸出到頁面文件流
if (!osName.contains("Windows")) {
exportFile = "進場交易確認書.pdf";
pathOut= GboatAppContext.getWebRootPath() + "download" + "/" + exportFile;
}
InputStream inStream = new FileInputStream(pathOut);
response.setHeader("Content-Type", "application/octet-stream");
// 設置response的編碼方式
response.setContentType("application/x-msdownload");
String headers = request.getHeader("User-Agent").toUpperCase();
if (headers.contains("MSIE") || headers.contains("TRIDENT") || headers.contains("EDGE")) {
exportFile = URLEncoder.encode(exportFile, "utf-8");
// IE下載文件名空格變+號問題

} else {

}
// 設置附加文件名

byte[] b = new byte[512];
int len;
ServletOutputStream outputStream = response.getOutputStream();
while ((len = inStream.read(b)) > 0) {
outputStream.write(b, 0, len);
}
inStream.close();
// 將寫入到客戶端的內存的數據,刷新到磁盤
outputStream.flush();
outputStream.close();
//更新評價狀態 是否下載了進場交易確認書
ArrivalEvaluation arrivalEvaluation =confirmationBusiness.getArrivalEvaluationByProjectId(projectId);
if(null != arrivalEvaluation && !"2".equals(arrivalEvaluation.getDownloadStatus())){
arrivalEvaluation.setDownloadStatus("2");
confirmationBusiness.update(arrivalEvaluation);
}
} catch (Exception e) {
GboatAppContext.output(JsonResult.createFailure(e.getMessage()));
}
}

當報錯時 Error: source file could not be loaded
解決時,應該 在執行語句上加上版本號
libreoffice --headless --invisible --convert-to pdf:writer_pdf_Export " + docxPath + " --outdir " + path;
用着這一方式可以加載到文件
libreoffice6.1 --headless --invisible --convert-to pdf:writer_pdf_Export " + docxPath + " --outdir " + path;
