Java中基于HttpServlet的反射机制（封装从view层页面接收到的数据于实体对象中）

一、实体类

package com.qf.pojo;

public class UserInfo{
	private int id;
	private String name;
	private int age;
	private String pwd;
	
	public UserInfo() {
		super();
	}

	public UserInfo(int id, String name, int age, String pwd) {
		super();
		this.id = id;
		this.name = name;
		this.age = age;
		this.pwd = pwd;
	}

	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 getAge() {
		return age;
	}

	public void setAge(int age) {
		this.age = age;
	}

	public String getPwd() {
		return pwd;
	}

	public void setPwd(String pwd) {
		this.pwd = pwd;
	}

	@Override
	public int hashCode() {
		final int prime = 31;
		int result = 1;
		result = prime * result + age;
		result = prime * result + id;
		result = prime * result + ((name == null) ? 0 : name.hashCode());
		result = prime * result + ((pwd == null) ? 0 : pwd.hashCode());
		return result;
	}

	@Override
	public boolean equals(Object obj) {
		if (this == obj)
			return true;
		if (obj == null)
			return false;
		if (getClass() != obj.getClass())
			return false;
		UserInfo other = (UserInfo) obj;
		if (age != other.age)
			return false;
		if (id != other.id)
			return false;
		if (name == null) {
			if (other.name != null)
				return false;
		} else if (!name.equals(other.name))
			return false;
		if (pwd == null) {
			if (other.pwd != null)
				return false;
		} else if (!pwd.equals(other.pwd))
			return false;
		return true;
	}

	@Override
	public String toString() {
		return "UserInfo [id=" + id + ", name=" + name + ", age=" + age + ", pwd=" + pwd + "]";
	}
	
	
}
