图书管理系统

图书管理系统

1、搭建数据库

这里使用的是MySQL数据库

创建一个存放书籍数据的数据库表

CREATE DATABASE `ssmbuild`;

USE `ssmbuild`;

DROP TABLE IF EXISTS `books`;

CREATE TABLE `books` (
`bookID` INT(10) NOT NULL AUTO_INCREMENT COMMENT '书id',
`bookName` VARCHAR(100) NOT NULL COMMENT '书名',
`bookCounts` INT(11) NOT NULL COMMENT '数量',
`detail` VARCHAR(200) NOT NULL COMMENT '描述',
KEY `bookID` (`bookID`)
) ENGINE=INNODB DEFAULT CHARSET=utf8

INSERT  INTO `books`(`bookID`,`bookName`,`bookCounts`,`detail`)VALUES
(1,'Java',1,'从入门到放弃'),
(2,'MySQL',10,'从删库到跑路'),
(3,'Linux',5,'从进门到进牢');

2、基本环境搭建

2.1、创建新项目

打开IDEA创建一个新的普通Maven项目

2.2、添加web支持

2.3、导入相关的pom依赖

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>
</project>

2.4、建立基本结构和配置框架！

在java右键新建package

• com.dahai.pojo
• com.dahai.dao
• com.dahai.service
• com.dahai.controller
• com.dahai.utils

在resource右键新建File

• applicationContext.xml
• database.properties
• mybatis-config.xml
• spring-dao.xml
• spring-mvc.xml
• spring-service.xml

mybatis-config.xml的基础代码

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
       PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
       "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

</configuration>

applicationContext.xml的基础代码

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd">

</beans>

3、Mybatis层编写

3.1、数据库配置文件

database.properties

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=123456

3.2、编写数据库对应的实体类Pojo

com.dahai.pojo.Books

使用到lombok插件！

package com.dahai.pojo;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class Books {

    private int bookID;
    private String bookName;
    private int bookCounts;
    private String detail;
}

3.3、编写Dao层的 Mapper接口！

com.dahai.dao.Mapper

package com.dahai.dao;

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

import java.util.List;

public interface BookMapper {

    //增加一本书
    int addBook(Books books);

    //删除一本书
    int deleteBookById(@Param("bookId") int id);

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

    //查前一本书
    Books queryBookById(@Param("bookId") int id);

    //查询全部的书
    List<Books> queryAllBook();

    //通过书名查书
//    Books queryBookByName(@Param("bookName") String bookName);

    //通过书名查书(模糊查询)
    List<Books>  queryBookByName(@Param("bookName") String bookName);

}

3.4、编写接口对应的 Mapper.xml 文件

com.dahai.dao.Mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.dahai.dao.BookMapper">

    <!--增加一本书-->
    <insert id="addBook" parameterType="Books">
        insert into ssmbuild.books(bookName, bookCounts, detail)
        values (#{bookName}, #{bookCounts}, #{detail});
    </insert>
    
    <!--删除一本书-->
    <delete id="deleteBookById" parameterType="int">
        delete from ssmbuild.books where bookID = #{bookId}
    </delete>

    <!--更新一本书-->
    <update id="updateBook" parameterType="Books">
        update ssmbuild.books
        set bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID=#{bookID};
    </update>

    <!--更新一本书（包括ID修改）-->
<!--    <update id="updateBook" parameterType="Books">
        update ssmbuild.books
        set bookID=#{bookID},bookName=#{bookName},bookCounts=#{bookCounts},detail=#{detail}
        where bookID=#{bookID};
    </update>-->

    <!--查询一本书-->
    <select id="queryBookById" resultType="Books">
        select * from ssmbuild.books
        where bookID=#{bookId};
    </select>

    <!--查询全部的书-->
    <select id="queryAllBook" resultType="Books">
        select * from ssmbuild.books;
    </select>

<!--    &lt;!&ndash;通过书名查书&ndash;&gt;-->
<!--    <select id="queryBookByName" resultType="Books">-->
<!--        select * from ssmbuild.books where bookName = #{bookName};-->
<!--    </select>-->


<!--    select * from ssmbuild.books where bookName like concat('%',#{bookName},'%')-->
    <!--根据书名模糊查询-->
    <select id="queryBookByName" resultType="Books">
        select * from ssmbuild.books where bookName like concat('%',#{bookName},'%')
    </select>
</mapper>

3.5、编写MyBatis的核心配置文件

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

    <settings>
        <setting name="logImpl" value="STDOUT_LOGGING"/>
    </settings>

    <!--配置数据源，交给Spring去做-->
    <typeAliases>
        <package name="com.dahai.pojo"/>
    </typeAliases>

    <mappers>
        <mapper resource="com/dahai/dao/BookMapper.xml"/>
    </mappers>
</configuration>

3.6、编写BookService

com.dahai.service.BookService

package com.dahai.service;

import com.dahai.pojo.Books;

import java.util.List;

//BookService:底下需要去实现,调用dao层
public interface BookService {

    //增加一本书
    int addBook(Books books);

    //删除一本书
    int deleteBookById(int id);

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

    //查前一本书
    Books queryBookById(int id);

    //查询全部的书
    List<Books> queryAllBook();

    //通过书名查书
//    Books queryBookByName(String bookName);
    List<Books> queryBookByName(String bookName);
}

3.7、编写BookBookServiceImpl

com.dahai.service.BookServiceImpl

package com.dahai.service;

import com.dahai.dao.BookMapper;
import com.dahai.pojo.Books;

import java.util.List;

public class BookServiceImpl implements BookService{

    //service调dao层：组合Dao
    private BookMapper bookMapper;

    public void setBookMapper(BookMapper bookMapper) {
        this.bookMapper = bookMapper;
    }

    @Override
    public int addBook(Books books) {
        return bookMapper.addBook(books);
    }

    @Override
    public int deleteBookById(int id) {
        return bookMapper.deleteBookById(id);
    }

    @Override
    public int updateBook(Books books) {
        System.out.println("BookServiceImpl: updateBook=>"+books);
        return bookMapper.updateBook(books);
    }

    @Override
    public Books queryBookById(int id) {
        return bookMapper.queryBookById(id);
    }

    @Override
    public List<Books> queryAllBook() {
        return bookMapper.queryAllBook();
    }

    @Override
    public List<Books> queryBookByName(String bookName) {
        return bookMapper.queryBookByName(bookName);
    }

}

4、Spring层编写
