Building a Library Management Module with SSM Framework

Prerequisites

Required developmant environment:

  • IntelliJ IDEA
  • MySQL 5.7.19
  • Tomcat 9
  • Maven 3.6

Required knowledge: Proficiency in MySQL, Spring, JavaWeb, and MyBatis, along with basic frontend skills.

Database Initialization

Create a schema for storing publication records:

CREATE DATABASE `library_db`;
USE `library_db`;

DROP TABLE IF EXISTS `publications`;
CREATE TABLE `publications` (
`pub_id` INT(10) NOT NULL AUTO_INCREMENT COMMENT 'Publication ID',
`title` VARCHAR(100) NOT NULL COMMENT 'Publication Title',
`stock` INT(11) NOT NULL COMMENT 'Available Stock',
`description` VARCHAR(200) NOT NULL COMMENT 'Description',
PRIMARY KEY (`pub_id`)
) ENGINE=INNODB DEFAULT CHARSET=utf8;

INSERT INTO `publications`(`pub_id`, `title`, `stock`, `description`) VALUES
(1, 'Mastering Java', 1, 'From入门 to 放弃'),
(2, 'Advanced MySQL', 10, 'From 删库 to 跑路'),
(3, 'Linux Operations', 5, 'From 进门 to 进牢');

Project Structure Setup

Create a Maven project named library-ssm and enable Web Application support. Organize the packages as follows:

  • com.example.pojo (Entities)
  • com.example.mapper (DAO)
  • com.example.service (Business Logic)
  • com.example.controller (Web Layer)

Dependency Configuration (pom.xml)

Import the necessary libraries for JUnit, MySQL, C3P0, Servlet/JSP, MyBatis, and Spring:

    </dependency>
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>

Resource Filtering

Ensure XML and properteis files in the source directories are copied to the output:

<build>
    <resources>
        <resource>
            <directory>src/main/java</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.properties</include>
                <include>**/*.xml</include>
            </includes>
            <filtering>false</filtering>
        </resource>
    </resources>
</build>

MyBatis Layer Implementation

1. Database connection properties (jdbc.properties):

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/library_db?useSSL=true&useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=123456

2. MyBatis Configuration (mybatis-config.xml):

<?xml version="1.0" encoding="UTF-8" ?>

<configuration>
    <typeAliases>
        <package name="com.example.pojo"/>
    </typeAliases>
    <mappers>
        <mapper resource="com/example/mapper/PublicationMapper.xml"/>
    </mappers>
</configuration>

3. Entity Class (Publication.java):

package com.example.pojo;

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

@Data
@NoArgsConstructor
@AllArgsConstructor
public class Publication {
    private int pubId;
    private String title;
    private int stock;
    private String description;
}

4. Mapper Interface (PublicationMapper.java):

package com.example.mapper;

import com.example.pojo.Publication;
import java.util.List;

public interface PublicationMapper {
    int insertPublication(Publication publication);
    int removePublicationById(int id);
    int editPublication(Publication publication);
    Publication findPublicationById(int id);
    List<Publication> fetchAllPublications();
}

5. Mapper XML (PublicationMapper.xml):

<?xml version="1.0" encoding="UTF-8" ?>

<mapper namespace="com.example.mapper.PublicationMapper">
    <insert id="insertPublication" parameterType="Publication">
        INSERT INTO library_db.publications(title, stock, description)
        VALUES (#{title}, #{stock}, #{description})
    </insert>
    <delete id="removePublicationById" parameterType="int">
        DELETE FROM library_db.publications WHERE pub_id = #{pubId}
    </delete>
    <update id="editPublication" parameterType="Publication">
        UPDATE library_db.publications
        SET title = #{title}, stock = #{stock}, description = #{description}
        WHERE pub_id = #{pubId}
    </update>
    <select id="findPublicationById" resultType="Publication">
        SELECT * FROM library_db.publications WHERE pub_id = #{pubId}
    </select>
    <select id="fetchAllPublications" resultType="Publication">
        SELECT * FROM library_db.publications
    </select>
</mapper>

6. Service Interface (PublicationService.java):

package com.example.service;

import com.example.pojo.Publication;
import java.util.List;

public interface PublicationService {
    int add(Publication publication);
    int delete(int id);
    int update(Publication publication);
    Publication getById(int id);
    List<Publication> getAll();
}

7. Service Implementation (PublicationServiceImpl.java):

package com.example.service;

import com.example.mapper.PublicationMapper;
import com.example.pojo.Publication;
import java.util.List;

public class PublicationServiceImpl implements PublicationService {
    private PublicationMapper publicationMapper;

    public void setPublicationMapper(PublicationMapper publicationMapper) {
        this.publicationMapper = publicationMapper;
    }

    public int add(Publication publication) {
        return publicationMapper.insertPublication(publication);
    }

    public int delete(int id) {
        return publicationMapper.removePublicationById(id);
    }

    public int update(Publication publication) {
        return publicationMapper.editPublication(publication);
    }

    public Publication getById(int id) {
        return publicationMapper.findPublicationById(id);
    }

    public List<Publication> getAll() {
        return publicationMapper.fetchAllPublications();
    }
}
