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 {

        PreparedStatement ps=conn.prepareStatement(sql);
        ps.setString(1, s.getName());
        ps.setDouble(2, s.getScore());
        ps.setObject(3, s.getBirth());
        ps.setString(4, s.getCity());

        ps.executeUpdate();

        JdbcUtil.release(conn);
    }

    public void add2(Goods s) throws SQLException {

    }



    public void detele2(int id) throws SQLException {

//        ps.setObject(3, s.getBirth());
//        ps.setString(4, s.getCity());
        ps.setInt(3, s.getId());
        ps.executeUpdate();
        JdbcUtil.release(conn);
    }

    public void update3(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 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();

    }

    public int update4(Goods s) {
        ListDao sDao =new ListDao();

            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) {

            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 {

        } catch (SQLException e) {
            e.printStackTrace();
            return -1;
        }
    }
}
