一、前言
在上篇博客中，介绍了RuoYi中如何实现文件的上传与下载，那么这篇博客讲一下如何在RuoYi中使用富文本编辑器，这部分的内容是向Ｂ站程序员青戈学习的，当然我这里就会把学到的内容做一个总结，当然也会说一下在RuoYi中使用富文本编辑器会出现的一些问题。希望对大家有所帮助！
二、准备工作
1、安装wangdietor
npm install @wangeditor/editor --save
2、导入相关的包
三、Vue代码
首先我想说一下使用这个wangdietor富文本编辑器的主要思路：先对需要使用wangdietor的字段绑定标签id=''editor"，然后使用我们自己写的setRichText()函数对编辑器进行初始化和对一些图片、视频上传的接口进行自定义；最后要将富文本编辑器的内容存在数据中。当然数据显示的时候可能会有一些标签，此时我们可以通过按钮，出现弹窗来规避这种情况。
核心代码如下：
setRichText(){
this.$nextTick( () => {
this.editor=new E('#editor')//创建对象
this.editor.highlight = hljs//代码高亮
this.editor.config.uploadImgServer = process.env.VUE_APP_BASE_API+'/file/editor/upload'//图片上传的接口
this.editor.config.uploadFileName = 'file'
this.editor.config.uploadImgParams = {
type:"img"
}
this.editor.config.uploadVideoServer = process.env.VUE_APP_BASE_API+"/file/editor/upload"//视频上传的接口
this.editor.config.uploadVideoName = 'file'
this.editor.config.uploadVideoParams = {
type:"video"
}
this.editor.create()
})
}四、Java代码
后端代码主要就是在图片和视频的上传了，下面是wangdietor规定的图片和视频的上传的格式
核心代码如下：
@RestController
@Api(tags = "文件上传与下载模块")
@RequestMapping("/file")
public class FileController extends BaseController {
@Value("${ip:localhost}")
String ip;//通过配置文件拿到ip
@Value("${server.port}")
String port;
private static final String ROOT_PATH = System.getProperty("user.dir")+ File.separator+"files";//文件根目录
@PostMapping("/editor/upload")
public Dict editorUpload(MultipartFile file,@RequestParam String type) throws IOException {
System.out.println(6767);
String originalFilename = file.getOriginalFilename();
String mainName = FileUtil.mainName(originalFilename);
String extName = FileUtil.extName(originalFilename);
if(!FileUtil.exist(ROOT_PATH)){
FileUtil.mkdir(ROOT_PATH);
}
if(FileUtil.exist(ROOT_PATH+File.separator+originalFilename)){
originalFilename=System.currentTimeMillis()+"_"+mainName+"."+extName;
}
File saveFile = new File(ROOT_PATH + File.separator + originalFilename);
file.transferTo(saveFile);
String url ="http://"+ip+":"+port+"/file/download/"+originalFilename;
if("img".equals(type)){//上传图片
return Dict.create().set("errno",0).set("data", CollUtil.newArrayList(Dict.create().set("url",url)));
}else if("video".equals(type)){
return Dict.create().set("errno",0).set("data", Dict.create().set("url",url));
}
return Dict.create().set("errno",0);
}
@ApiOperation(value = "文件下载")
@GetMapping("/download/{fileName}")
public void download(@PathVariable String fileName, HttpServletResponse response) throws IOException {
// response.addHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName,"UTF-8"));//文件下载
// response.addHeader("Content-Disposition", "inline;filename=" + URLEncoder.encode(fileName,"UTF-8"));//文件预览
String filePath = ROOT_PATH+File.separator+fileName;//拿到文件的路径
if(!FileUtil.exist(filePath)){//文件不存在，就不用管，因为没有东西可写
return;
}
byte[] bytes = FileUtil.readBytes(filePath);//使用FileUtil从filePath中去读取文件
ServletOutputStream outputStream = response.getOutputStream();
outputStream.write(bytes);//把文件的字节数写出去
outputStream.flush();//刷新一下
outputStream.close();//一定要关闭文件流
}
}
后端报错
如果出现这个错误，我们改一下对应的XSS中的内容即可
效果图
全部代码
以下的代码是包含了上述效果图中的所有代码，至于一些按钮、弹窗的设计、数据的请求与显示在该代码中都有，都是一些比较小的点，我就不详细介绍了，大家感兴趣的话就在评论区评论就好了，我看到了都会回复的。
