实现
1、搭建SpringBoot+Vue前后端分离项目
若依前后端分离版本地搭建开发环境并运行项目的教程：
若依前后端分离版手把手教你本地搭建环境并运行项目_BADAO_LIUMANG_QIZHI的博客-CSDN博客
2、设计表
数据库语句为
DROP TABLE IF EXISTS `bus_file_preview`;
CREATE TABLE `bus_file_preview` (
`id` bigint(0) NOT NULL AUTO_INCREMENT COMMENT '主键',
`fileName` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '原文件名（上传前文件名）',
`fileType` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '文件后缀（.xls;.xlsx;.ppt;.doc;.docx;.pptx）',
`uploadPath` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '上传后文件路径',
`uploadFileName` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '上传后文件名',
`pdfPath` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '转换pdf路径',
`pdfName` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '转换pdf文件名',
`create_time` datetime(0) NULL DEFAULT NULL COMMENT '创建时间',
`create_by` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL COMMENT '创建人',
`update_time` datetime(0) NULL DEFAULT NULL COMMENT '更新时间',
`update_by` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL COMMENT '更新人',
`remark` varchar(255) CHARACTER SET utf8 COLLATE utf8_bin NULL DEFAULT NULL COMMENT '备注',
`preview_url` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL COMMENT '预览URL',
PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 21 CHARACTER SET = utf8 COLLATE = utf8_general_ci COMMENT = '文件上传与预览' ROW_FORMAT = Dynamic;
SET FOREIGN_KEY_CHECKS = 1;依照此表生成前后端代码，然后修改代码。
3、文件上传实现
前端按钮
上传
提示：仅允许导入“.doc、.docx、.xls、.ppt、.xlsx、.pptx”格式文件！
调用的各方法
// 文件上传失败
uploadError(err) {
this.btnLoding = false;
this.$message.error(res.msg);
},
// 上传中
uploadProgress(e) {
this.btnLoding = true;
},
// 文件上传之前
beforeUpload(file) {
console.log(file, "上传之前");
const fileName = file.name;
const fileType = fileName.substring(fileName.lastIndexOf("."));
if (
fileType === ".doc" ||
fileType === ".docx" ||
fileType === ".xls" ||
fileType === ".ppt" ||
fileType === ".pptx" ||
fileType === ".xlsx"
) {
this.form.filename = file.name;
// 不处理
} else {
this.$message.error("请上传正确的文件类型,.doc,.docx,.xls,.ppt,.xlsx,.pptx,");
return false;
}
},
// 文件上传成功
uploadSuccess(res, file, fileList) {
this.form.uploadpath = res.uploadpath;
this.btnLoding = false;
this.fileList = fileList;
this.$message(res.msg);
},
beyond(file, fileList) {
this.$message({
message: "最多上传一个文件",
type: "warning",
});
},
// 移除选择的文件
fileRemove(file, fileList) {
this.btnLoding = false;
this.reset();
this.fileList = [];
},对应后台SpingBoot通用上传接口
这里做了修改，使其能返回磁盘路径
/**
* 通用上传请求返回磁盘路径
*/
@PostMapping("/common/uploadWithAbsolutePath")
public AjaxResult uploadFileWithAbsolutePath(MultipartFile file) throws Exception
{
try
{
// 上传文件路径
String filePath = RuoYiConfig.getUploadPath();
// 上传并返回新文件名称
String fileName = FileUploadUtils.uploadWithAbsolutePath(filePath, file);
AjaxResult ajax = AjaxResult.success();
ajax.put("uploadpath", filePath+ File.separator+fileName);
return ajax;
}
catch (Exception e)
{
return AjaxResult.error(e.getMessage());
}
}调用的方法uploadWithAbsolutePath实现
public static final String uploadWithAbsolutePath(String baseDir, MultipartFile file) throws IOException
{
try
{
return uploadWithAbsolutePath(baseDir, file, MimeTypeUtils.DEFAULT_ALLOWED_EXTENSION);
}
catch (Exception e)
{
throw new IOException(e.getMessage(), e);
}
}其中又调用的uploadWithAbsolutePath方法实现
public static final String uploadWithAbsolutePath(String baseDir, MultipartFile file, String[] allowedExtension)
throws FileSizeLimitExceededException, IOException, FileNameLengthLimitExceededException,
InvalidExtensionException
{
int fileNamelength = file.getOriginalFilename().length();
if (fileNamelength > FileUploadUtils.DEFAULT_FILE_NAME_LENGTH)
{
throw new FileNameLengthLimitExceededException(FileUploadUtils.DEFAULT_FILE_NAME_LENGTH);
}
assertAllowed(file, allowedExtension);
String fileName = extractFilename(file);
File desc = getAbsoluteFile(baseDir, fileName);
file.transferTo(desc);
return fileName;
}其他的若依框架原来的方法。
上传效果
4、预览实现
上传之后的文件转换成pdf的实现，在提交按钮时调用后台就接口
/** 提交按钮 */
submitForm() {
this.$refs["form"].validate((valid) => {
if (valid) {
if (this.form.id != null) {
updatePreview(this.form).then((response) => {
this.msgSuccess("修改成功");
this.open = false;
this.fileList = [];
this.getList();
});
} else {
addPreview(this.form).then((response) => {
this.msgSuccess("新增成功");
this.open = false;
this.fileList = [];
this.getList();
});
}
}
});
},首先是新增接口
/**
* 新增preview
*/
@Log(title = "preview", businessType = BusinessType.INSERT)
@PostMapping
public AjaxResult add(@RequestBody BusFilePreview busFilePreview) throws IOException{
if (StringUtils.isNull(busFilePreview.getFilename())) {
AjaxResult.error("缺少文件名称");
}
if (StringUtils.isNull(busFilePreview.getUploadpath())) {
AjaxResult.error("缺少上传文件路径");
}
String substringAfter = StringUtils.substringAfter(busFilePreview.getUploadpath(), ".");
String upName = StringUtils.substringAfterLast(busFilePreview.getUploadpath(), "/");
busFilePreview.setUploadfilename(upName);
busFilePreview.setFiletype(substringAfter); //类型
if ("pdf".equals(substringAfter)){
FilePdfUtils.copyFile(busFilePreview.getUploadpath(), RuoYiConfig.getProfile());
String pdfName = StringUtils.substringAfterLast(busFilePreview.getUploadpath(), "/");
busFilePreview.setPdfpath(RuoYiConfig.getProfile()+ "/" + pdfName);
busFilePreview.setPdfname(pdfName);
return toAjax(busFilePreviewService.insertBusFilePreview(busFilePreview));
}
File file = new File(busFilePreview.getUploadpath());
FileInputStream fileInputStream = new FileInputStream(file);
String htmFileName = FilePdfUtils.file2pdf(fileInputStream, substringAfter,RuoYiConfig.getProfile());
String pdfPath = RuoYiConfig.getProfile()+ "/" + htmFileName;
busFilePreview.setPdfpath(pdfPath);
String pdfName = StringUtils.substringAfterLast(pdfPath, "/");
busFilePreview.setPdfname(pdfName);
String previewUrl = serverConfig.getUrl()+ Constants.RESOURCE_PREFIX+File.separator+htmFileName;
busFilePreview.setPreviewUrl(previewUrl);
return toAjax(busFilePreviewService.insertBusFilePreview(busFilePreview));
}这里调用了工具类中FilePdfUtils的file2pdf方法，并且将转换后的pdf的路径拼接成静态资源映射后的路径返回给前端。
关于静态资源映射可以参考如下
SpringBoot中通过重写WebMvcConfigurer的方法配置静态资源映射实现图片上传后返回网络Url：

5、FilePdfUtils工具类实现
package com.ruoyi.common.utils.pdf;
import com.artofsolving.jodconverter.DocumentConverter;
import com.artofsolving.jodconverter.openoffice.connection.OpenOfficeConnection;
import com.artofsolving.jodconverter.openoffice.connection.SocketOpenOfficeConnection;
import com.artofsolving.jodconverter.openoffice.converter.StreamOpenOfficeDocumentConverter;
import com.ruoyi.common.utils.StringUtils;
import java.io.*;
import java.net.ConnectException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class FilePdfUtils {
/**
* 转换文件成pdf
*
* @param fromFileInputStream:
* @throws IOException
*/
public static String file2pdf(InputStream fromFileInputStream, String type,String pdfPath) throws IOException {
Date date = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmss");
String timesuffix = sdf.format(date);
String docFileName = null;
String htmFileName = null;
if("doc".equals(type)){
docFileName = "doc_" + timesuffix + ".doc";
htmFileName = "doc_" + timesuffix + ".pdf";
}else if("docx".equals(type)){
docFileName = "docx_" + timesuffix + ".docx";
htmFileName = "docx_" + timesuffix + ".pdf";
}else if("xls".equals(type)){
docFileName = "xls_" + timesuffix + ".xls";
htmFileName = "xls_" + timesuffix + ".pdf";
}else if("ppt".equals(type)){
docFileName = "ppt_" + timesuffix + ".ppt";
htmFileName = "ppt_" + timesuffix + ".pdf";
}else if("xlsx".equals(type)){
docFileName = "xlsx_" + timesuffix + ".xlsx";
htmFileName = "xlsx_" + timesuffix + ".pdf";
}else if("pptx".equals(type)){
docFileName = "pptx_" + timesuffix + ".pptx";
htmFileName = "pptx_" + timesuffix + ".pdf";
}else{
return null;
}
check_folder(pdfPath);
File htmlOutputFile = new File(pdfPath + File.separatorChar + htmFileName);
File docInputFile = new File(pdfPath + File.separatorChar + docFileName);
if (htmlOutputFile.exists())
htmlOutputFile.delete();
htmlOutputFile.createNewFile();
if (docInputFile.exists())
docInputFile.delete();
docInputFile.createNewFile();
/**
* 由fromFileInputStream构建输入文件
*/
try {
OutputStream os = new FileOutputStream(docInputFile);
int bytesRead = 0;
byte[] buffer = new byte[1024 * 8];
while ((bytesRead = fromFileInputStream.read(buffer)) != -1) {
os.write(buffer, 0, bytesRead);
}
os.close();
fromFileInputStream.close();
} catch (IOException e) {
}
OpenOfficeConnection connection = new SocketOpenOfficeConnection(8100);
try {
connection.connect();
} catch (ConnectException e) {
System.err.println("文件转换出错，请检查OpenOffice服务是否启动。");
}
DocumentConverter converter = new StreamOpenOfficeDocumentConverter(connection);
converter.convert(docInputFile, htmlOutputFile);
connection.disconnect();
// 转换完之后删除word文件
docInputFile.delete();
System.out.println(htmFileName);
return htmFileName;
}
public static void check_folder(String path) {
File dir = new File(path);
// 判断文件夹是否存在
if (dir.isDirectory()) {
} else {
dir.mkdirs();
}
}
public static void copyFile(String oldPath, String newPath) throws IOException {
File oldFile = new File(oldPath);//获取旧的文件File对象
File file = new File(newPath + oldFile.separator + StringUtils.substringAfterLast(oldPath, "/")); //获取新的文件File对象并生成文件
FileInputStream in = new FileInputStream(oldFile); //
FileOutputStream out = new FileOutputStream(file);
byte[] buffer=new byte[2097152];
int readByte = 0;
//读取旧文件的流写入新文件里
while((readByte = in.read(buffer)) != -1){
out.write(buffer, 0, readByte);
}
in.close();
out.close();
}
}注意这里的连接openOffice的服务的端口要对应并且确保openOffice已经启动
然后工具类FilePdfUtils是在common模块下，所以后台需要在此模块下pom文件中添加依赖
com.artofsolving
jodconverter
2.2.1
添加位置
注意这里的版本为2.2.1，Maven中央仓库中此为最高版本
这里在调用工具类转换文件时，如果文件类型为docx、pptx、xlsx时会报错提示
unknown document format for file ....docx
这是因为2.2.1的能转换doc ,但2.2.2才能转换docx,如果你用2.2.1的jar包,转换2.2.2的docx文档就会出错
除了不加载Maven中央仓库的2.1的依赖之外，还可以重写DocumentFormatRegistry接口的getFormatByFileExtension方法
注意包名一致
package com.artofsolving.jodconverter;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
/**
* @ClassName: online
* @description: 重写 BasicDocumentFormatRegistry 文档格式
* @Author: yandongfa
* @Data: 2020-03-24 19:47
* @Version: 1.0
**/
public class BasicDocumentFormatRegistry implements DocumentFormatRegistry {
private List/* */ documentFormats = new ArrayList();
public void addDocumentFormat(DocumentFormat documentFormat) {
documentFormats.add(documentFormat);
}
protected List/* */ getDocumentFormats() {
return documentFormats;
}
/**
* @param extension
* the file extension
* @return the DocumentFormat for this extension, or null if the extension
* is not mapped
*/
public DocumentFormat getFormatByFileExtension(String extension) {
if (extension == null) {
return null;
}
//new DefaultDocumentFormatRegistry();
//将文件名后缀统一转化
if (extension.indexOf("doc") >= 0) {
extension = "doc";
}
if (extension.indexOf("ppt") >= 0) {
extension = "ppt";
}
if (extension.indexOf("xls") >= 0) {
extension = "xls";
}
String lowerExtension = extension.toLowerCase();
for (Iterator it = documentFormats.iterator(); it.hasNext();) {
DocumentFormat format = (DocumentFormat) it.next();
if (format.getFileExtension().equals(lowerExtension)) {
return format;
}
}
return null;
}
public DocumentFormat getFormatByMimeType(String mimeType) {
for (Iterator it = documentFormats.iterator(); it.hasNext();) {
DocumentFormat format = (DocumentFormat) it.next();
if (format.getMimeType().equals(mimeType)) {
return format;
}
}
return null;
}
} 6、在线预览实现
预览 调用js方法
// 预览
handlePreview(row) {
let url = row.previewUrl;
window.open(url);
},这里直接打开url这个字段对应的地址即可，url是在进行文件转换成pdf时生成的映射的服务器上的url
String previewUrl = serverConfig.getUrl()+ Constants.RESOURCE_PREFIX+File.separator+htmFileName;注意这里的预览地址如果有拦截，让在后台配置中放开白名单。
7、文件下载实现
// 下载
handleDownload(row) {
const baseURL = process.env.VUE_APP_BASE_API
window.location.href = baseURL + "/common/download/resourceeasy?resource=" + encodeURI(row.uploadpath);
},
这里直接修改后台的下载本地资源的通用下载方法
@GetMapping("/common/download/resourceeasy")
public void resourceDownloadEasy(String resource, HttpServletRequest request, HttpServletResponse response)
throws Exception
{
try
{
if (!FileUtils.checkAllowDownload(resource))
{
throw new Exception(StringUtils.format("资源文件({})非法，不允许下载。 ", resource));
}
response.setContentType(MediaType.APPLICATION_OCTET_STREAM_VALUE);
FileUtils.setAttachmentResponseHeader(response, resource);
FileUtils.writeBytes(resource, response.getOutputStream());
}
catch (Exception e)
{
log.error("下载文件失败", e);
}
}下载效果
