在MySql中创建数据库表

向数据库表中添加数据

在Eclipse中创建数据库表对应的实体类

package com.qf.entity;

public class Product {
	private String id;
	private String risk;
	private String income;
	private String saleStarting;
	private String saleEnd;
	private String end;
	
	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getRisk() {
		return risk;
	}

	public void setRisk(String risk) {
		this.risk = risk;
	}

	public String getIncome() {
		return income;
	}

	public void setIncome(String income) {
		this.income = income;
	}

	public String getSaleStarting() {
		return saleStarting;
	}

	public void setSaleStarting(String saleStarting) {
		this.saleStarting = saleStarting;
	}

	public String getSaleEnd() {
		return saleEnd;
	}

	public void setSaleEnd(String saleEnd) {
		this.saleEnd = saleEnd;
	}

	public String getEnd() {
		return end;
	}

	public void setEnd(String end) {
		this.end = end;
	}

	@Override
	public String toString() {
		return "Product [id=" + id + ", risk=" + risk + ", income=" + income + ", saleStarting=" + saleStarting
				+ ", saleEnd=" + saleEnd + ", end=" + end + "]";
	}
	
}

创建jdbc工具类

package com.qf.dao;
/**
