一、数据库建表语句

DROP TABLE IF EXISTS `m_book`;CREATE TABLE `m_book` (  `id` varchar(255) NOT NULL,  `bname` varchar(255) DEFAULT NULL,  `btime` datetime DEFAULT NULL,  `price` double DEFAULT NULL,  PRIMARY KEY (`id`))

二、

1dao层接口（注：mybatis默认返回int）

package com.test.dao;import com.test.model.Book;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 IBookDao {    @Insert("insert into m_book(id,bname,btime,price) values(#{book_id},#{book_name},#{book_time},#{book_price})")    public Integer addBook(Book book);    @Delete("delete from m_book where id=#{book_id}")    public Integer delBook(String id);    @Update("update m_book set bname=#book_name},btime=#{book_time},price=#{book_price} where id=#{book_id}")    public Integer updateBook(Book Book);    @Select("select * from m_book")    public List getAllBooK();}

2设置扫描你写的接口与注解

其他省略
