基于Swing和Mysql的简单的仓库管理系统
内容导读
互联网集市收集整理的这篇技术教程文章主要介绍了基于Swing和Mysql的简单的仓库管理系统，小编现在分享给大家，供广大互联网技能从业者学习和参考。文章包含23144字，纯文字阅读大概需要34分钟。
内容图文
本系统包含两个模块：仓库模块、记录模块
仓库模块功能：入库，出库，修改，删除，查询
记录模块功能：查询
接下来展示代码：
首先确定涉及到两个表，那就要做两个Bean类
public class Goods {
private int id;
private String name;
private int number;
public Goods(){
super();
}
public Goods(int id, String name, int number) {
this.id = id;
this.name = name;
this.number = number;
}
public Goods(String name, int number) {
this.name = name;
this.number = number;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
}
}
import java.time.LocalDate;
public class Lists {
private int id;
private String name;
private double score;
private LocalDate birth;
private String city;
public String getWay() {
return way;
}
public void setWay(String way) {
this.way = way;
}
private String way;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getScore() {
return score;
}
public void setScore(double score) {
this.score = score;
}
public LocalDate getBirth() {
return birth;
}
public void setBirth(LocalDate birth) {
this.birth = birth;
}
public String getCity() {
return city;
}
public void setCity(String city) {
this.city = city;
}
public Lists(String name, double score, LocalDate birth, String city,String way) {
super();
this.name = name;
this.score = score;
this.birth = birth;
this.city = city;
this.way = way;
}
@Override
public String toString() {
return "Student [id=" + id + ", name=" + name + ", score=" + score + ", birth=" + birth + ", city=" + city
+", way=" + way
+ "]";
}
public Lists() {
super();
}
}
Util类
既然涉及到数据库，那就离不开JDBC，所以首先要创建工具类，同时还有一个数据处理的工具类
import com.mchange.v2.c3p0.ComboPooledDataSource;
import java.io.FileInputStream;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.SQLException;
import java.util.Properties;
public class JdbcUtil {
public static final ComboPooledDataSource ds=new ComboPooledDataSource();
static
{
//加载连接数据库的信息
try {
InputStream is =new FileInputStream("jdbc.properties");
Properties porp =new Properties();
porp.load(is);
is.close();
//获取连接数据库信息
String user =porp.getProperty("user");
String pwd =porp.getProperty("pwd");
String url=porp.getProperty("url");
String driver =porp.getProperty("driver");
//设置链接库的信息
ds.setUser(user);
ds.setDriverClass(driver);
ds.setJdbcUrl(url);
ds.setPassword(pwd);
} catch (Exception e) {
e.printStackTrace();
}
}
public static Connection getConnection() {
try {
return ds.getConnection();
} catch (SQLException e) {
e.printStackTrace();
}
return null;
}
public static void release(Connection conn) {
try {
conn.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
import java.time.LocalDate;
import java.util.Date;
import java.util.List;
public class DateUtil {
//将日期转换为字符串
public static LocalDate dateToLocalDate(Date date) {
return LocalDate.ofEpochDay(date.getTime()/86400000).plusDays(1);
}
public static Object[][] listToArray(List<Lists> stus){
Object[][] data=new Object[stus.size()][];
int size=stus.size();
for(int i=0;i<size;i++) {
Lists s = stus.get(i);
Object[] info =new Object[] {s.getId(),s.getName(),s.getScore(),s.getBirth(),s.getCity(),s.getWay()};
data[i]=info;
}
return data;
}
public static Object[][] listToArray2(List<Goods> stus){
Object[][] data=new Object[stus.size()][];
int size=stus.size();
for(int i=0;i<size;i++) {
Goods s = stus.get(i);
Object[] info =new Object[] {s.getId(),s.getName(),s.getNumber()};
data[i]=info;
}
return data;
}
}
接下来是Dao层
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
public class ListDao {
public void add(Lists s) throws SQLException {

String sql="insert into stus values(null,?,?,?,?,?)";

ps.setDouble(2, s.getScore());
ps.setObject(3, s.getBirth());
ps.setString(4, s.getCity());
ps.setString(5, s.getWay());
ps.executeUpdate();
JdbcUtil.release(conn);
}
public void add2(Goods s) throws SQLException {
Connection conn = JdbcUtil.getConnection();
String sql="insert into good values(null,?,?)";
PreparedStatement ps=conn.prepareStatement(sql);
ps.setString(1, s.getName());
ps.setInt(2, s.getNumber());

ps.executeUpdate();
JdbcUtil.release(conn);
}
public void detele2(int id) throws SQLException {

String sql="delete from good where id=?";
PreparedStatement ps=conn.prepareStatement(sql);
ps.setInt(1, id);
ps.executeUpdate();
JdbcUtil.release(conn);
}
public void update2(Goods s) throws SQLException {

PreparedStatement ps=conn.prepareStatement(sql);

ps.executeUpdate();
JdbcUtil.release(conn);
}
public void update3(Goods s) throws SQLException {

String sql="UPDATE good SET score = score-? WHERE NAME=?";
PreparedStatement ps=conn.prepareStatement(sql);
ps.setDouble(1, s.getNumber());
ps.setString(2, s.getName());
ps.executeUpdate();
JdbcUtil.release(conn);
}
public void update4(Goods s) throws SQLException {
Connection conn = JdbcUtil.getConnection();
String sql="UPDATE good SET score = score+? WHERE NAME=?";
PreparedStatement ps=conn.prepareStatement(sql);
ps.setDouble(1, s.getNumber());
ps.setString(2, s.getName());
ps.executeUpdate();
JdbcUtil.release(conn);
}
public List<Lists> queryAll() throws SQLException{
List<Lists> stus=new ArrayList<>();
Connection conn = JdbcUtil.getConnection();
String sql="select * from stus";
PreparedStatement ps=conn.prepareStatement(sql);
ResultSet rs = ps.executeQuery();
while(rs.next()) {
Lists s=new Lists();
s.setId(rs.getInt(1));
s.setName(rs.getString(2));
s.setScore(rs.getDouble(3));
s.setBirth(DateUtil.dateToLocalDate(rs.getDate(4)));
s.setCity(rs.getString(5));
s.setWay(rs.getString(6));
stus.add(s);
}
JdbcUtil.release(conn);
return stus;
}
public List<Goods> queryAll2() throws SQLException{
List<Goods> stus=new ArrayList<>();
Connection conn = JdbcUtil.getConnection();
String sql="select * from good";
PreparedStatement ps=conn.prepareStatement(sql);
ResultSet rs = ps.executeQuery();
while(rs.next()) {
Goods g = new Goods();
g.setId(rs.getInt(1));
g.setName(rs.getString(2));
g.setNumber(rs.getInt(3));
stus.add(g);
}
JdbcUtil.release(conn);
return stus;
}
}
Service层
import java.sql.SQLException;
import java.util.List;
public class ListService {
public List<Lists> queryAll(){
try {
return new ListDao().queryAll();
} catch (SQLException e) {
e.printStackTrace();
}
return null;
}
public List<Goods> queryAll2(){
try {
return new ListDao().queryAll2();
} catch (SQLException e) {
e.printStackTrace();
}
return null;
}
public int update2(Goods s) {
ListDao sDao =new ListDao();
try {
sDao.update2(s);
return 0;
} catch (SQLException e) {
e.printStackTrace();
return -1;
}
}
public int update3(Goods s) {
ListDao sDao =new ListDao();
try {
sDao.update3(s);
return 0;
} catch (SQLException e) {
e.printStackTrace();
return -1;
}
}
public int update4(Goods s) {
ListDao sDao =new ListDao();
try {
sDao.update4(s);
return 0;
} catch (SQLException e) {
e.printStackTrace();
return -1;
}
}
public int delete2(int id) {
ListDao sDao =new ListDao();
try {
sDao.detele2(id);
return 0;
} catch (SQLException e) {
e.printStackTrace();
return -1;
}
}
public int insert(Lists s) {
ListDao sDao =new ListDao();
try {
sDao.add(s);
return 0;
} catch (SQLException e) {
e.printStackTrace();
return -1;
}
}
public int insert2(Goods s) {
ListDao sDao =new ListDao();
try {
sDao.add2(s);
return 0;
} catch (SQLException e) {
e.printStackTrace();
return -1;
}
}
}
