建立Bilibili排行榜信息 JAVA

建立Bilibili排行榜信息

• 建立数据库

  • 

  • 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',

• 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

  • 

• 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;

        @Autowired

        public void Insert() {
            Bilibilirank bilibilirank = new Bilibilirank();
            bilibilirank.setAid("1");
            bilibilirankMapper.insert(bilibilirank);
        }
    }
    
    

    修改主要逻辑代码

            }
            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
