项目学习：仿b站的视频网站项目06 -视频分类02

概括

本篇文章主要是构建了发布视频所需要的四张表的sql，以及对应的预上传部分的代码，仅供参考,参考视频在13集

数据库文件

部分后端代码

通过代码生器生成部分代码后，需要将部分代码移动到指定的项目文件夹后。下面给出一些部分工具类和公共方法代码，来帮助你更快的去完善项目。最好还是自己能够手动编写，来熟悉。

新增SysSettingDto 类，该类主要是用来提供校验配置的一些数据量，之后会转移到配置文件中

package com.easylive.entity.dto;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import org.springframework.stereotype.Component;

import java.io.Serializable;

@JsonIgnoreProperties(ignoreUnknown = true)
public class SysSettingDto implements Serializable {
    private static final long serialVersionUID = 1L;
    private Integer registerCoinCount = 10;
    private Integer postVideoCoinCount = 10;
    private Integer videoSize = 5;
    private Integer videoPCount = 10;
    private Integer videoCount = 10;
    private Integer commentCount = 20;
    private Integer danmuCount = 20;


    public Integer getRegisterCoinCount() {
        return registerCoinCount;
    }

    public void setRegisterCoinCount(Integer registerCoinCount) {
        this.registerCoinCount = registerCoinCount;
    }

    public Integer getPostVideoCoinCount() {
        return postVideoCoinCount;
    }

    public void setPostVideoCoinCount(Integer postVideoCoinCount) {
        this.postVideoCoinCount = postVideoCoinCount;
    }

    public Integer getVideoSize() {
        return videoSize;
    }

    public void setVideoSize(Integer videoSize) {
        this.videoSize = videoSize;
    }

    public Integer getVideoPCount() {
        return videoPCount;
    }

    public void setVideoPCount(Integer videoPCount) {
        this.videoPCount = videoPCount;
    }

    public Integer getVideoCount() {
        return videoCount;
    }

    public void setVideoCount(Integer videoCount) {
        this.videoCount = videoCount;
    }

    public Integer getCommentCount() {
        return commentCount;
    }

    public void setCommentCount(Integer commentCount) {
        this.commentCount = commentCount;
    }

    public Integer getDanmuCount() {
        return danmuCount;
    }

    public void setDanmuCount(Integer danmuCount) {
        this.danmuCount = danmuCount;
    }
}

新增UploadingFileDto 类，该类主要是用来提供文件上传的部分数据

package com.easylive.entity.dto;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

import java.io.Serializable;

@JsonIgnoreProperties(ignoreUnknown = true)
public class UploadingFileDto implements Serializable {
    private static final long serialVersionUID = 1L;
    private String fileName;
    private String uploadId;
    private Integer chunkIndex;
    private Integer chunks;
    private Long fileSize = 0L;
    private String filePath;

    public String getFileName() {
        return fileName;
    }

    public void setFileName(String fileName) {
        this.fileName = fileName;
    }

    public String getUploadId() {
        return uploadId;
    }

    public void setUploadId(String uploadId) {
        this.uploadId = uploadId;
    }

    public Integer getChunkIndex() {
        return chunkIndex;
    }

    public void setChunkIndex(Integer chunkIndex) {
        this.chunkIndex = chunkIndex;
    }

    public Integer getChunks() {
        return chunks;
    }

    public void setChunks(Integer chunks) {
        this.chunks = chunks;
    }

    public Long getFileSize() {
        return fileSize;
    }

    public void setFileSize(Long fileSize) {
        this.fileSize = fileSize;
    }

    public String getFilePath() {
        return filePath;
    }

    public void setFilePath(String filePath) {
        this.filePath = filePath;
    }

    @Override
    public String toString() {
        return "UploadingFileDto{" +
                "fileName='" + fileName + '\'' +
                ", uploadId='" + uploadId + '\'' +
                ", chunkIndex=" + chunkIndex +
                ", chunks=" + chunks +
                ", fileSize=" + fileSize +
                ", filePath='" + filePath + '\'' +
                '}';
    }
}
