Java GUI，mybatis实现资产管理系统

Java GUI——资产管理系统

前言：为了做java课设，学了一手Java GUI。感觉蛮有意思的，写写文章，做个视频记录一下。欢迎大家友善指出我的不足

资产管理系统录制视频，从头敲到尾

模块划分

• 资产信息管理
  • 资产信息查询 【各种条件查询】
  • 资产信息修改（不能对资产进行领用、归还、报废）
  • 资产信息增加
  • 资产信息删除
• 人员信息管理
  • 人员信息查询 【各种条件查询】
  • 人员信息修改
  • 人员信息增加
  • 人员信息删除
• 资产设备领用、归还、报废
  • 资产设备操作（仅限于领用、归还、报废）
  • 资产设备查询 【各种条件】

数据库创建

资产表

DROP TABLE IF EXISTS `asset_information`;
CREATE TABLE `asset_information`  (
  `asset_number` int NOT NULL AUTO_INCREMENT COMMENT '资产编号',
  `asset_name` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '资产名称',
  `price` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '价格',

  `status` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '状态 0-默认 1-领用 2-归还 3-报废',
  `remarks` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '备注',
  PRIMARY KEY (`asset_number`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 1007 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_croatian_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of asset_information
-- ----------------------------
INSERT INTO `asset_information` VALUES (1000, '潇洒哥', '1000', '', '1', '');
INSERT INTO `asset_information` VALUES (1004, '潇洒哥', '10000', '2020-09-07 14:52:54', '0', '是个蛋');

资产操作流水表

DROP TABLE IF EXISTS `asset_operation_log`;
CREATE TABLE `asset_operation_log`  (
  `operation_number` int NOT NULL AUTO_INCREMENT COMMENT '操作编号',
  `operation_type` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '操作类型 0-默认 1-领用 2-归还 3-报废',

  `operation_time` datetime NULL DEFAULT NULL COMMENT '操作时间',
  `recipient` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '操作人',
  `remarks` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '备注',
  PRIMARY KEY (`operation_number`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 4 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_croatian_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of asset_operation_log
-- ----------------------------
INSERT INTO `asset_operation_log` VALUES (5, '1', '1000', NULL, '1', '无');

人员信息表

DROP TABLE IF EXISTS `personnel_information`;
CREATE TABLE `personnel_information`  (
  `personnel_number` int NOT NULL AUTO_INCREMENT COMMENT '人员编号',
  `name` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '姓名',
  `gender` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '性别',
  `department` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '部门',
  `position` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '职位',
  `other` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_croatian_ci NULL DEFAULT NULL COMMENT '其他信息',
  PRIMARY KEY (`personnel_number`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 4 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_croatian_ci ROW_FORMAT = Dynamic;

-- ----------------------------
-- Records of personnel_information
-- ----------------------------
INSERT INTO `personnel_information` VALUES (1, '潇洒哥', '男', '羊村', '大哥', '是个蛋，白色的蛋蛋');
INSERT INTO `personnel_information` VALUES (2, '飞鸽', '男', '鸽子部门', '二弟', '飞哥不鸽');
INSERT INTO `personnel_information` VALUES (3, '老王', '女', '军乐团', '团长', '牛逼啊');

业务流程

资产被人员操作后，操作记录写入资产记录表。同时根据人员的操作修改资产本身的信息。

本项目采用模块划编写。不同模块划分为不同的包，每个包下维护若干类，每个类表示一个UI界面。

模块一：主界面

1.1）创建主界面UI

用代码构建如下界面, 但不具备界面跳转等操作

package com.xhf.keshe;

import com.xhf.keshe.asset.AssetQuery;

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Main extends JFrame {
    /**
     * 窗体宽
     */
    public static final int width = 800;
    /**
     * 窗体高
     */
    public static final int height = 600;
    /**
     * 基本字体
     */
    public static final Font font = new Font("仿宋", Font.BOLD, 20);
    /**
     * 创建基本界面
     */
    private JPanel workspace;

    public Main() {
        // 创建窗体
        setTitle("资产管理系统");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(width, height);

        // 创建基本界面
        initBasePanel();

        // 居中
        setLocationRelativeTo(null);

        // 初始化界面
        initUI();
    }

    /**
     * 创建基本界面
     */
    private void initBasePanel() {
        this.workspace = new JPanel();
        workspace.setLayout(null);
        JLabel jLabel = new JLabel("欢迎使用资产管理系统", JLabel.CENTER);    //创建一个标签
        jLabel.setBounds(140, 100, 400, 60);
        jLabel.setFont(Main.font);
        workspace.add(jLabel, BorderLayout.NORTH);
        add(workspace);
    }

    /**
     * 初始化界面
     */
    private void initUI() {
        // 添加菜单栏组件
        JMenuBar jMenuBar = new JMenuBar();

        // 在菜单栏(bar)中添加若干菜单(menu)
        String[] jMenuNameList = {"资产信息管理", "人员信息管理", "资产设备管理"};
        for (int i = 0; i < 3; ++i) {
            // jMenu的名称
            String jMenuName = jMenuNameList[i];
            JMenu jMenu = new JMenu(jMenuName);
            // 为menu添加item
            addItemForJMenu(jMenu, jMenuName);
            // 设置字体
            jMenu.setFont(font);
            // 将jMenu添加到bar中
            jMenuBar.add(jMenu);
        }

        // 添加jMenuBar
        setJMenuBar(jMenuBar);
    }

    /**
     * 为不同名称的jMenu添加item
     * @param jMenu
     * @param jMenuName
     */
    private void addItemForJMenu(JMenu jMenu, String jMenuName) {
        String[] item1NameList = {"资产信息查询", "资产信息修改", "资产信息增加", "资产信息删除"};
        String[] item2NameList = {"人员信息查询", "人员信息修改", "人员信息增加", "人员信息删除"};
        String[] item3NameList = {"资产设备查询", "资产设备操作"};

        // 判断jMenu名称, 然后添加item
        switch (jMenuName) {
            case "资产信息管理":
                for (String s : item1NameList) {
                    addItem(s, jMenu);
                }
                break;
            case "人员信息管理":
                for (String s : item2NameList) {
                    addItem(s, jMenu);
                }
                break;
            case "资产设备管理":
                for (String s : item3NameList) {
                    addItem(s, jMenu);
                }
                break;
        }
    }

    /**
     * 创建jMenuItem, 同时取名name, 将item添加到menu中
     * @param name
     * @param jMenu
     */
    private void addItem(String name, JMenu jMenu) {
        JMenuItem item = new JMenuItem(name);
        item.setFont(font);
        jMenu.add(item);
    }

    public static void main(String[] args) {
        Main main = new Main();
        main.setVisible(true);
    }
}

1.2）增加主界面的界面跳转逻辑

所有的界面跳转，都可以理解为以下几个操作

1. 触发相应操作
2. 清除当前界面
3. 添加需要界面
4. 界面重新渲染

分析可知，通过点击item，才触发界面跳转的操作。因此我们需要给不同的item上添加相应的监听器，用于执行界面跳转的逻辑

    /**
     * 创建jMenuItem, 同时取名name, 将item添加到menu中
     * @param name
     * @param jMenu
     */
    private void addItem(String name, JMenu jMenu) {
        JMenuItem item = new JMenuItem(name);
        // 为不同的item添加监听操作
        item.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                // 为不同的item添加不同的界面
                switch (name) {
                    case "资产信息查询":
                        // 清空当前界面
                        remove(workspace);
                        // 添加想要的界面
                        workspace = new AssetQuery();
                        add(workspace);
                        // 重新绘制界面
                        validate();
                        break;
                }
            }
        });
        item.setFont(font);
        jMenu.add(item);
    }

模块二： 资产界面

2.1）mybatis整合

学习资料

(44条消息) Mybatis基本使用教程（小白向）_敲代码它不香嘛的博客-CSDN博客

入门_MyBatis中文网

2.2.1) 编写mybatis-config.xml

DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <environments default="development">
        <environment id="development">
            <transactionManager type="JDBC"/>
            <dataSource type="POOLED">
                <property name="driver" value="com.mysql.cj.jdbc.Driver"/>
                <property name="url" value="jdbc:mysql://localhost:3306/keshe1"/>
                <property name="username" value="root"/>
                <property name="password" value="root"/>
            dataSource>
        environment>
    environments>
    <mappers>
        
        <mapper resource="mapper/assetInformationMapper.xml"/>
        <mapper resource="mapper/personnelInformationMapper.xml"/>
        <mapper resource="mapper/operateMapper.xml"/>
    mappers>
configuration>

如下图，编写mybatis-config.xml【核心配置文件】文件，放置在resources根目录

2.2.2) 获取SqlSession

sqlsession是mybatis中的核心工具，有了它才有后续操作。sqlsession封装jdbc的数据库连接操作

package com.xhf.keshe.utils;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;

import java.io.IOException;
import java.io.InputStream;

public class GetSqlsession {
    private static InputStream inputStream;

	//这个方法生成一个生产Sqlsession的工厂，即SqlSessionFactory
    public static SqlSessionFactory createfactory() {
		
        {
            try {
                inputStream = Resources.getResourceAsStream("mybatis-config.xml");
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
        //通过把这个工厂return出来，以便后续通过这个工厂获得SqlSession对象
        return sqlSessionFactory;
    }

	//这个方法获得SqlSession对象
    public static SqlSession getsqlsession(){
        return createfactory().openSession();
    }
}

2.2.3）编写实体类

package com.xhf.keshe.asset.entity;

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

import java.io.Serializable;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class AssetInformation implements Serializable {

    private static final long serialVersionUID = 1L;

    /**
     * 资产编号
     */
    private Integer assetNumber;

    /**
     * 资产名称
     */
    private String assetName;

    /**
     * 价格
     */
    private String price;

    /**
     * 购买日期
     */
    private String purchaseDate;

    /**
     * 状态 0-默认 1-领用 2-归还 3-报废
     */
    private String status;

    /**
     * 备注
     */
    private String remarks;
}

2.2.5) 编写mapper接口

package com.xhf.keshe.asset.mapper;

import com.xhf.keshe.asset.entity.AssetInformation;
import org.apache.ibatis.annotations.Param;

import java.util.List;

public interface AssetInformationMapper {
    /**
     * 查询全部信息
     * @return
     */
    List<AssetInformation> list();
    /**
     * 根据id查询数据
     */
    AssetInformation listById(@Param("id") String id);
    /**
     * 修改
     */
    void update(@Param("entity") AssetInformation entity);
    /**
     * 新增数据
     */
    void insert(@Param("entity") AssetInformation entity);
    /**
     * 根据id删除数据
     */
    void deleteById(@Param("id") Integer id);
}

2.2.6）编写mapper的xml文件

DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xhf.keshe.asset.mapper.AssetInformationMapper">

    <resultMap id="BaseResultMap" type="com.xhf.keshe.asset.entity.AssetInformation" >
        <result column="asset_number" property="assetNumber" />
        <result column="asset_name" property="assetName" />
        <result column="price" property="price" />
        <result column="purchase_date" property="purchaseDate" />
        <result column="status" property="status" />
        <result column="remarks" property="remarks" />
    resultMap>

    <insert id="insert" useGeneratedKeys="true" keyProperty="assetNumber">
        INSERT INTO
            asset_information
        VALUES (
            null,
            #{entity.assetName},
            #{entity.price},
            #{entity.purchaseDate},
            #{entity.status},
            #{entity.remarks}
            );
    insert>
    <update id="update">
        UPDATE asset_information
        <set>
            <if test="entity.assetName != null"> asset_name = #{entity.assetName}, if>
            <if test="entity.price != null"> price = #{entity.price}, if>

            <if test="entity.remarks"> remarks = #{entity.remarks} if>
        set>
        WHERE
            asset_information.asset_number = #{entity.assetNumber}
    update>
    <delete id="deleteById">
        DELETE FROM asset_information WHERE asset_information.asset_number = #{id};

    select>
    <select id="listById" resultMap="BaseResultMap">

    select>

mapper>

2.2）查询界面UI

package com.xhf.keshe.asset.page;

import com.xhf.keshe.Main;
import com.xhf.keshe.asset.entity.AssetInformation;
import com.xhf.keshe.asset.mapper.AssetInformationMapper;
import com.xhf.keshe.utils.GetSqlsession;
import org.apache.ibatis.session.SqlSession;

import javax.swing.*;
import java.awt.*;
import java.util.List;


/**

 */
public class AssetQuery extends JPanel {
    // 表格列名
    public static final String[] columnNames = {"资产编号", "资产名称", "价格", "购买日期", "状态", "备注"};
    /**
     * sqlsession
     */
    private SqlSession sqlSession;
    /**
     * mapper
     */
    private AssetInformationMapper mapper;

    {
        sqlSession = GetSqlsession.getsqlsession();
        mapper = sqlSession.getMapper(AssetInformationMapper.class);
    }

    public AssetQuery() {

        // 设置每行的高度
        table.setRowHeight(25);
        // 设置表内容字体
        table.setFont(Main.font);

        // 将表格添加到滚动面板，并将滚动面板添加到窗口
        JScrollPane scrollPane = new JScrollPane(table);
        this.add(scrollPane);
    }

    /**
     * 返回资产表格数据

     */
    private Object[][] getData() {
        // 返回list数据
        List<AssetInformation> list = mapper.list();
        Object[][] data = new Object[list.size()][columnNames.length];
        // 将list处理为二维数组, 赋值给data
        for (int i = 0; i < list.size(); i++) {

        add(jButton);
    }
}

模块三：人员界面

3.1）mybatis整合

3.1.1）编写实体类

package com.xhf.keshe.person.entity;

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

import java.io.Serializable;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class PersonnelInformation implements Serializable {

    private static final long serialVersionUID = 1L;
    /**
    * 人员编号
    */
    private Integer personnelNumber;

    /**
    * 姓名
    */
    private String name;

    /**
    * 性别
    */
    private String gender;

    /**
    * 部门
    */
    private String department;

    /**
    * 职位
    */
    private String position;

    /**
    * 其他信息
    */
    private String other;
}

3.1.2）编写mapper接口

package com.xhf.keshe.person.mapper;

import com.xhf.keshe.person.entity.PersonnelInformation;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import java.util.List;

@Mapper
public interface PersonnelInformationMapper {
    /**
     * 查询全部信息
     * @return
     */
    List<PersonnelInformation> list();
    /**
     * 根据id查询数据
     */
    PersonnelInformation listById(@Param("id") String id);
    /**
     * 修改
     */
    void update(@Param("entity") PersonnelInformation entity);
    /**
     * 新增数据
     */
    void insert(@Param("entity") PersonnelInformation entity);
    /**
     * 根据id删除数据
     */
    void deleteById(@Param("id") Integer id);
}

3.1.3）编写mapper的xml文件

DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xhf.keshe.person.mapper.PersonnelInformationMapper">

            #{entity.gender},
            #{entity.department},
            #{entity.position},

        )
    insert>
    <update id="update">

            `position` = #{entity.position},
            other = #{entity.other}
        WHERE
            personnel_number = #{entity.personnelNumber};
    update>
    <delete id="deleteById">
        DELETE FROM personnel_information WHERE personnel_number = #{id};
    delete>
    <select id="list" resultMap="BaseResultMap">
        SELECT * FROM personnel_information;
    select>
    <select id="listById" resultMap="BaseResultMap">
        SELECT * FROM personnel_information WHERE personnel_number = #{id};
    select>

模块四：资产操作

4.1）mybatis整合

4.1.1）编写实体类

package com.xhf.keshe.operate.entity;

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

import java.io.Serializable;
import java.util.Date;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class AssetOperationLog implements Serializable {

    private static final long serialVersionUID = 1L;
    /**
     * 操作编号
     */
    private Integer operationNumber;

    /**
     * 操作类型
     */
    private String operationType;

    /**
     * 资产编号
     */
    private String assetNumber;

    /**
     * 操作时间
     */
    private Date operationTime;

    /**
     * 领用人
     */
    private String recipient;
    /**
     * 备注
     */
    private String remarks;
}

4.1.2）编写mapper接口

package com.xhf.keshe.operate.mapper;

import com.xhf.keshe.operate.entity.AssetOperationLog;
import org.apache.ibatis.annotations.Mapper;
import org.apache.ibatis.annotations.Param;

import java.util.List;

@Mapper
public interface OperateMapper {
    /**
     * 查询所有数据
     * @return
     */
    List<AssetOperationLog> list();
    /**
     * 保存
     */
    void insert(@Param("entity") AssetOperationLog entity);
}

4.1.3）编写mapper的xml文件

DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.xhf.keshe.operate.mapper.OperateMapper">

    <resultMap id="BaseResultMap" type="com.xhf.keshe.operate.entity.AssetOperationLog" >

        <result column="asset_number" property="assetNumber" />
        <result column="operation_time" property="operationTime" />
        <result column="recipient" property="recipient" />
        <result column="remarks" property="remarks" />
    resultMap>
    <insert id="insert">
        INSERT INTO
            asset_operation_log
        VALUES (
            null,
            #{entity.operationType},
            #{entity.assetNumber},
            #{entity.operationTime},
            #{entity.recipient},
            #{entity.remarks}
        );
    insert>

    <select id="list" resultMap="BaseResultMap">
        SELECT * FROM asset_operation_log;
    select>

mapper>
