小张在此请各位朋友们给个赞啦！！！！当然有什么意见和建议也可以尽情的说，小张感激不尽！！！

仓库管理系统

注：初学者可能会出现导入问题，我就连导入的一起加上了（可以建个类直接复制，你懂的）

先在src目录下建4个包

分别是：net.wms.bean，net.wms.dao，net.wms.util，net.wms.view，

net.wms.bean包下的类

User类（用户类）

public class User {
	private int id;
	private String username; 
	private String userpwd;
	private String flag;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getusername() {
		return username;
	}
	public void setusername(String username) {
		this.username = username;
	}
	public String getuserpwd() {
		return userpwd;
	}
	public void setuserpwd(String userpwd) {
		this.userpwd = userpwd;
	}
	public String getFlag() {
		return flag;
	}
	public void setFlag(String flag) {
		this.flag = flag;
	}
}

Goods类（货物类）

public class Goods {
	private int id;
	private String goodsname;
	private String goodsstyle;
	private int goodsnumber;
	private String storageID;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getGoodsname() {
		return goodsname;
	}
	public void setGoodsname(String goodsname) {
		this.goodsname = goodsname;
	}
	public String getGoodsstyle() {
		return goodsstyle;
	}
	public void setGoodsstyle(String goodsstyle) {
		this.goodsstyle = goodsstyle;
	}
	public int getGoodsnumber() {
		return goodsnumber;
	}
	public void setGoodsnumber(int goodsnumber) {
		this.goodsnumber = goodsnumber;
	}
	public String getStorageID() {
		return storageID;
	}
	public void setStorageID(String storageID) {
		this.storageID = storageID;
	}	
}

Storage类（仓库类）

public class Storage {
	private int id;
	private String storagename;
	private String storagestyle;
	private int storageID;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getStoragename() {

	}
	public void setStoragename(String storagename) {

	}

	}

	}
	
}
