编写BooksMapper.java接口：

package com.itcast.dao;

import com.itcast.pojo.Books;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface BookMapper {
     
//  增加一本书
    public int addBook(Books books);

//  删除一本书
    public int deleteBookByID(@Param("bookID") int id);

//  更新一本书
    public int updateBook(Books books);

//  查询一本书
    public Books queryBookByID(@Param("bookID") int id);

//  查询全部书
    public List<Books> queryAllBook();

//  根据书名查找书籍
    public Books queryBooksByName(@Param("bookName") String bookName);
}

实现BooksMapper.xml:

<mapper namespace="com.itcast.dao.BookMapper">
    <insert id="addBook" parameterType="Books">
        insert into books (bookName,bookCounts,detail)
        values (#{bookName},#{bookCounts},#{detail});
    insert>

    <delete id="deleteBookByID" parameterType="int">
        delete from books where bookID = #{bookID};
    delete>

    <update id="updateBook" parameterType="Books">
        update books
        set bookName =  #{bookName},bookCounts = #{bookCounts},detail = #{detail}
        where bookID = #{bookID};
    update>

    <select id="queryBookByID" parameterType="int" resultType="Books">
        select * from books where bookID = #{bookID};
    select>

    <select id="queryAllBook" resultType="Books">

    <select id="queryBooksByName" resultType="Books">
