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

业务流程

在这里插入图片描述

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
在这里插入图片描述

在这里插入图片描述

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itemaddItemForJMenu(jMenu, jMenuName);// 设置字体jMenu.setFont(font);// 将jMenu添加到bar中jMenuBar.add(jMenu);}// 添加jMenuBarsetJMenuBar(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itemswitch (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() {@Overridepublic 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
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configurationPUBLIC "-//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><!--后续编写的mapper.xml都需要添加到这里--><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

image-20230710155452363
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SqlSessionFactorypublic 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
<?xml version="1.0" encoding="UTF-8"?>
<!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 INTOasset_informationVALUES (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.purchaseDate != null"> purchase_date = #{entity.purchaseDate}, </if><if test="entity.status"> status = #{entity.status}, </if><if test="entity.remarks"> remarks = #{entity.remarks} </if></set>WHEREasset_information.asset_number = #{entity.assetNumber}</update><delete id="deleteById">DELETE FROM asset_information WHERE asset_information.asset_number = #{id};</delete><select id="list" resultMap="BaseResultMap">SELECT * FROM asset_information;</select><select id="listById" resultMap="BaseResultMap">SELECT * FROM asset_information WHERE asset_number = #{id};</select></mapper>

2.2）查询界面UI

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
<?xml version="1.0" encoding="UTF-8"?>
<!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="operation_number" property="operationNumber" /><result column="operation_type" property="operationType" /><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 INTOasset_operation_logVALUES (null,#{entity.operationType},#{entity.assetNumber},#{entity.operationTime},#{entity.recipient},#{entity.remarks});</insert><select id="list" resultMap="BaseResultMap">SELECT * FROM asset_operation_log;</select></mapper>
