Spring04-xml配置实现增删改查

大致结构

                          

加入需要的包

                               

 

建立实体类domain/Customer

package com.lixin.domain;

import java.io.Serializable;
/*
 * 客户的实体类
 * 用DButils操作，使用要求：实体类中的属性和数据库的字段必须一致
 */
public class Customer implements Serializable{
	
	private long id;
	private String name;
	private String source;//来源
	private String industry;//行业
	private String level;//等级
	private String address;
	private String phone;
	
	
	
	public long getId() {
		return id;
	}
	public String getName() {
		return name;
	}
	public String getSource() {
		return source;
	}
	public String getIndustry() {
		return industry;
	}
	public String getLevel() {
		return level;
	}
	public String getAddress() {
		return address;
	}
	public String getPhone() {
		return phone;
	}
	public void setId(long id) {
		this.id = id;
	}
	public void setName(String name) {
		this.name = name;
	}
	public void setSource(String source) {
		this.source = source;
	}
	public void setIndustry(String industry) {
		this.industry = industry;
	}
	public void setLevel(String level) {
		this.level = level;
	}
	public void setAddress(String address) {
		this.address = address;
	}
	public void setPhone(String phone) {
		this.phone = phone;
	}
	@Override
	public String toString() {
		return "Customer [id=" + id + ", name=" + name + ", source=" + source + ", industry=" + industry + ", level="
				+ level + ", address=" + address + ", phone=" + phone + "]";
	}
