+# 纯注解开发，spring+Mybatis 步骤分解
+
+1. 建库建表
+
+2. 建Java项目
+
+3. 将项目的所有包，先建好
+
+ 1. entity 实体类包
+ 2. mapper Dao层的代理接口包
+ 3. service 业务层包
+ 4. controller 表示层包
+ 5. config 配置类包
+
+4. 在entity包下，创建实体类Video
+
+ 1. 根据表的字段，创建对应的属性
+
+ 2. set,get,toString,构造器
+
+ 3. ```java
+ @Data //提供getter,getter,toString方法
+ @AllArgsConstructor //全参
+ @NoArgsConstructor //无参构造器
+ public class Video {
+ private int videoId;
+ private String videoTitle;
+
+ // 做成标准类，javaBean类，1.属性私有，封装。2,提供getter,getter,toString方法 3,全参和无参构造器
+
+ }
+
+ ```
+
+5. 在mapper包里，创建一个VideoMapper接口
+
+ ```java
+ package com.demo.mapper;
+
+ import com.demo.entity.Video;
+ import org.apache.ibatis.annotations.Delete;
+ import org.apache.ibatis.annotations.Insert;
+ import org.apache.ibatis.annotations.Select;
+ import org.apache.ibatis.annotations.Update;
+
+ import java.util.List;
+
+ public interface VideoMapper {
+ // Dao层，为的是操作数据库，通过SQL语句，其实就是做CRUD
+ // CRUD是指在做计算处理时的增加(Create)、读取(Read)、更新(Update)和删除(Delete)几个单词的首字母简写
+ // 1.要实现CRUD,这里要写5个方法
+ // 2.在每个方法上方，写一个对应SQL语句类型的注解
+
+ // 1. 查询所有，返回一堆视频数据，所用集合来装List
