打开esplise,新建DynamicWeb项目
在src目录下建立Model的package
在package中建立User类
首先创建User类

package Model;

public class User {
	private int id;
	private String username;
	@Override
	public String toString() {
		return "User [id=" + id + ", username=" + username + ", password=" + password + "]";
	}
	public User()
	{
		super();
	}
	public User(int id, String username, String password) {
		super();
		this.id = id;
		this.username = username;
		this.password = password;
	}
	private String password;
	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 getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}

}

配置web.xml,在WEB-INF下面如果没有请创建在这里插入代码片
