本文主要是介绍建立Bilibili排行榜信息 JAVA,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

建立Bilibili排行榜信息

  • 建立数据库

    • image-20210930210133264

    • 导出的语句

      SET NAMES utf8mb4;
      SET FOREIGN_KEY_CHECKS = 0;
      
      -- ----------------------------
      -- Table structure for bilibilirank
      -- ----------------------------
      DROP TABLE IF EXISTS `bilibilirank`;
      CREATE TABLE `bilibilirank`  (
        `id` int(0) NOT NULL AUTO_INCREMENT COMMENT '主键',
        `rid` varchar(10) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '分区类型',
        `aid` varchar(15) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT 'aid',
        `bvid` varchar(15) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT 'bid',
        `typename` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '分区名字',
        `title` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '视频标题',
        `play` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '播放量',
        `review` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '评论量',
        `favoritea` varchar(20) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '收藏量',

        `pic` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_bin NULL DEFAULT NULL COMMENT '封面链接',
        PRIMARY KEY (`id`) USING BTREE
      ) ENGINE = InnoDB CHARACTER SET = utf8mb4 COLLATE = utf8mb4_bin ROW_FORMAT = Dynamic;
      
      SET FOREIGN_KEY_CHECKS = 1;
      
  • 通过mybatis-plus逆向生成实体类

    • 默认 均会使用代码构造器和mysql

    • 生成效果如下

    • image-20210930212043923

  • 调整代码

    • Controller层设置为Springboot的测试类 执行主要方法(下面是测试代码)

    • package edu.sdut.bilibili.controller;
      
      
      import edu.sdut.bilibili.service.impl.BilibilirankServiceImpl;
      import org.junit.jupiter.api.Test;
      import org.springframework.beans.factory.annotation.Autowired;
      import org.springframework.boot.test.context.SpringBootTest;
      
      /**
       * <p>
       *  bilibiliRank排行榜 主控制类
       * </p>
       *
       * @author qingyun
       * @since 2021-09-30
       */
      @SpringBootTest
      public class BilibilirankController {
      
          @Autowired
          BilibilirankServiceImpl bilibilirankService;
      
          @Test
          public void testInset(){
              bilibilirankService.Insert();
          }
      }
      
    • Service

    • package edu.sdut.bilibili.service.impl;
      
      import edu.sdut.bilibili.entity.Bilibilirank;
      import edu.sdut.bilibili.mapper.BilibilirankMapper;
      import edu.sdut.bilibili.service.IBilibilirankService;
      import com.baomidou.mybatisplus.extension.service.impl.ServiceImpl;
      import org.springframework.beans.factory.annotation.Autowired;
      import org.springframework.stereotype.Service;
      
      import javax.sql.DataSource;
      
      /**
       * <p>
       *  服务实现类
       * </p>
       *
       * @author qingyun
       * @since 2021-09-30
       */
      @Service
      public class BilibilirankServiceImpl extends ServiceImpl<BilibilirankMapper, Bilibilirank> implements IBilibilirankService {
      
          @Autowired
          BilibilirankMapper bilibilirankMapper;
      
          public void Insert() {
              Bilibilirank bilibilirank = new Bilibilirank();
              bilibilirank.setAid("1");
              bilibilirankMapper.insert(bilibilirank);
          }
      }
      
      

      修改主要逻辑代码

      package edu.sdut.bilibili.controller;
      
      
      import edu.sdut.bilibili.entity.Bilibilirank;

                          bilibilirank.setRid(Integer.toString(j));
                          bilibilirank.setAid(rows.getStr("aid"));

              return BiliBiliRankS;

      效果如下

      下面进行插入数据库操作,使用mybatis-plus的批量插入操作

      注:直接提供的批量插入并不是真的批量插入。读者请自行查找真正的批量插入
