初学构建小项目之仓库管理系统货物类型管理功能实现(三)

时间：2022-11-13 22:33:10

      上一篇博客把仓库管理系统的主页面实现了，主要是一些按钮布局的实现，这一篇博客才是真正涉及到仓库管理系统货物类型管理的实现功能。

      首先是货物类型表的建立。

     

CREATE TABLE t_goodsType(
	id INT PRIMARY KEY AUTO_INCREMENT,
	goodsTypeName VARCHAR(20) NOT NULL,
	goodsTypeDesc VARCHAR(20) NOT NULL
);
INSERT INTO t_goodsType VALUES(NULL, '水果类', '有关的各种水果'),
                              (NULL, '书籍类', '有关的各种书籍'),
                              (NULL, '手机类', '有关的各种手机');

     后台数据库的表建立好后，接下来就是用Java页面和windowbuilder 其功能了。

     首先在model包对数据库中仓库货物类别表的字段进行封装和对父类的构造方法进行多态的实现。

package com.panli.model;
/**
 * GoodsType实体类
 * @author Peter
 *
 */
public class GoodsType {
	
	private int id;
	private String goodsTypeName;
	private String goodsTypeDesc;
	/**
	 *继承自父类的构造方法
	 */
	public GoodsType() {
		super();
		// TODO Auto-generated constructor stub
	}
	
	/**
	 * 一个参数的构造方法
	 * @param goodsTypeName
	 */
	public GoodsType(String goodsTypeName) {
		super();
		this.goodsTypeName = goodsTypeName;
	}
	

	/**
	 * 一个参数的构造方法
	 * @param id
	 */
	public GoodsType(int id) {
		super();
		this.id = id;
	}

	/**
	 * 2个参数的构造方法
	 * @param goodsTypeName
	 * @param goodsTypeDesc
	 */
	public GoodsType(String goodsTypeName, String goodsTypeDesc) {
		super();
		this.goodsTypeName = goodsTypeName;
		this.goodsTypeDesc = goodsTypeDesc;
	}
	
	/**
	 * 3个参数构造方法
	 * @param id
	 * @param goodsTypeName
	 * @param goodsTypeDesc
	 */
	public GoodsType(int id, String goodsTypeName, String goodsTypeDesc) {
		super();
		this.id = id;
		this.goodsTypeName = goodsTypeName;
		this.goodsTypeDesc = goodsTypeDesc;
	}

	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getGoodsTypeName() {
		return goodsTypeName;
	}
	public void setGoodsTypeName(String goodsTypeName) {
		this.goodsTypeName = goodsTypeName;
	}
	public String getGoodsTypeDesc() {
		return goodsTypeDesc;
	}
	public void setGoodsTypeDesc(String goodsTypeDesc) {
		this.goodsTypeDesc = goodsTypeDesc;
	}
}
    

      然后是在dao层对数据库仓库类别表进行增删改查操作控制

package com.panli.dao;

import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import com.panli.model.GoodsType;
import com.panli.util.StringUtil;

/**
 * 对GoodsType操作进行控制的类
 * @author Peter
 *
 */
public class GoodsTypeDao {
	
	/**
	 * 货物类别删除事件
	 * @param conn
	 * @param goodsType
	 * @return
	 * @throws SQLException
	 */
	public static int deleteGoodsType(Connection conn, GoodsType goodsType) throws SQLException{
		String sql = "delete from t_goodsType where id = ?";
		PreparedStatement pstmt = conn.prepareStatement(sql);
		pstmt.setInt(1, goodsType.getId());
		return pstmt.executeUpdate();
	}
	
	/**
	 * 货物类别更新事件
	 * @param conn
	 * @param goodsType
	 * @return
	 * @throws Exception
	 */
	public static int updateGoodsType(Connection conn, GoodsType goodsType) throws Exception{
		
		String sql = " update t_goodsType set goodsTypeName=?, goodsTypeDesc=? where id=?";
		PreparedStatement pstmt = conn.prepareStatement(sql);
		pstmt.setString(1, goodsType.getGoodsTypeName());
		pstmt.setString(2, goodsType.getGoodsTypeDesc());
		pstmt.setInt(3, goodsType.getId());
		return pstmt.executeUpdate();
	}
	
	
	/**
	 * 货物列表查询事件
	 * @param conn
	 * @param goodsType
	 * @return
	 * @throws Exception
	 */
	public static ResultSet listGoodsType(Connection conn, GoodsType goodsType) throws Exception{
		StringBuffer sb = new StringBuffer("select * from t_goodsType");
		if(StringUtil.isNotEmpty(goodsType.getGoodsTypeName())){
			sb.append(" and goodsTypeName like '%"+goodsType.getGoodsTypeName()+"%' ");
		}
		PreparedStatement pstmt = conn.prepareStatement(sb.toString().replaceFirst("and", "where"));
		return pstmt.executeQuery();
	}
	/**
	 *货物类别添加事件 
	 * @param conn
	 * @param goodsType
	 * @return
	 * @throws SQLException
	 */
	public static int addGoodsType(Connection conn, GoodsType goodsType) throws SQLException{
		String sql = "insert into t_goodsType values(null, ?, ?)";
		PreparedStatement pstmt = conn.prepareStatement(sql);
		pstmt.setString(1, goodsType.getGoodsTypeName());
		pstmt.setString(2, goodsType.getGoodsTypeDesc());
		return pstmt.executeUpdate();
	}
}

      最后是在视图层进行显示：
