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;}@Overridepublic 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;
/*** jdbc工具类* @author Administrator**/import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;public class DBUtils {public static Connection conn=null;public static PreparedStatement state=null;public static ResultSet rs=null;/*** 获得连接对象的发方法* @throws ClassNotFoundException * @throws SQLException * */public static Connection getConnection() throws ClassNotFoundException, SQLException {Class.forName("com.mysql.jdbc.Driver");conn=DriverManager.getConnection("jdbc:mysql://localhost:3306/lianxi", "root", "147258");return conn;}/*** jdbc增加修改删除的方法* @param sql * @param obs 动态参数* @return*/public static int update(String sql,Object...obs) {int result=0;try {DBUtils.getConnection();state=conn.prepareStatement(sql);for (int i = 0; i < obs.length; i++) {state.setObject(i+1, obs[i]);}result=state.executeUpdate();} catch (Exception e) {e.printStackTrace();}return result;}/*** jdbc查询的方法* @param sql * @param obs 动态参数* @return*/public static ResultSet query(String sql,Object...obs) {try {DBUtils.getConnection();state=conn.prepareStatement(sql);for (int i = 0; i < obs.length; i++) {state.setObject(i+1, obs[i]);}rs=state.executeQuery();}catch (Exception e) {e.printStackTrace();}return rs;}/*** 关闭jdbc对象的方法*/public static void closeObject() {try {if(rs!=null) {rs.close();}if(state!=null) {state.close();}if(conn!=null) {conn.close();}} catch (Exception e) {e.printStackTrace();}}}

创建对数据库表进行操作的DAO类

package com.qf.dao;import java.sql.SQLException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.List;import com.qf.entity.Product;public class ProductDAO {/*** 查找数据库表中所有信息的方法* @return*/public List<Product> queryAllProductInformation() {List<Product> pros=new ArrayList<Product>();try {String sql="select Id,Risk,Income,SaleStarting,SaleEnd,End from FinancingProduct order by SaleStarting desc";DBUtils.rs=DBUtils.query(sql);while(DBUtils.rs.next()) {Product p=new Product();p.setId(DBUtils.rs.getString("Id"));p.setRisk(DBUtils.rs.getString("Risk"));p.setIncome(DBUtils.rs.getString("Income"));SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");p.setSaleStarting(sdf.format(DBUtils.rs.getDate("SaleStarting")));p.setSaleEnd(sdf.format(DBUtils.rs.getDate("SaleEnd")));p.setEnd(sdf.format(DBUtils.rs.getDate("End")));pros.add(p);}} catch (SQLException e) {e.printStackTrace();} finally {DBUtils.closeObject();}return pros;}/*** 根据输入的产品代码和风险评级查找理财信息* @param id 用户输入的产品代码* @param risk 用户选择的风险评级* @return*/public List<Product> queryProduct(String id, String risk) {List<Product> pros=new ArrayList<Product>();try {String sql="select Id,Risk,Income,SaleStarting,SaleEnd,End from FinancingProduct where Id like ? and Risk=? order by SaleStarting desc";DBUtils.rs=DBUtils.query(sql,"%"+id+"%",risk);while(DBUtils.rs.next()) {Product p=new Product();p.setId(DBUtils.rs.getString("Id"));p.setRisk(DBUtils.rs.getString("Risk"));p.setIncome(DBUtils.rs.getString("Income"));SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");p.setSaleStarting(sdf.format(DBUtils.rs.getDate("SaleStarting")));p.setSaleEnd(sdf.format(DBUtils.rs.getDate("SaleEnd")));p.setEnd(sdf.format(DBUtils.rs.getDate("End")));pros.add(p);}} catch (SQLException e) {e.printStackTrace();} finally {DBUtils.closeObject();}return pros;}public List<Product> queryProductById(String id) {List<Product> pros=new ArrayList<Product>();try {String sql="select Id,Risk,Income,SaleStarting,SaleEnd,End from FinancingProduct where Id like ? order by SaleStarting desc";DBUtils.rs=DBUtils.query(sql,"%"+id+"%");while(DBUtils.rs.next()) {Product p=new Product();p.setId(DBUtils.rs.getString("Id"));p.setRisk(DBUtils.rs.getString("Risk"));p.setIncome(DBUtils.rs.getString("Income"));SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");p.setSaleStarting(sdf.format(DBUtils.rs.getDate("SaleStarting")));p.setSaleEnd(sdf.format(DBUtils.rs.getDate("SaleEnd")));p.setEnd(sdf.format(DBUtils.rs.getDate("End")));pros.add(p);}} catch (SQLException e) {e.printStackTrace();} finally {DBUtils.closeObject();}return pros;}public int qureyId(Product p) {int result=0;try {String sql="select count(Id) from FinancingProduct where Id=?";DBUtils.rs=DBUtils.query(sql,p.getId());while(DBUtils.rs.next()) {result=(DBUtils.rs.getInt(1));}} catch (SQLException e) {e.printStackTrace();} finally {DBUtils.closeObject();}return result;}public int addProduct(Product p) {String sql="insert into FinancingProduct(Id,Risk,Income,SaleStarting,SaleEnd,End) values(?,?,?,?,?,?)";int result=DBUtils.update(sql,p.getId(),p.getRisk(),p.getIncome(),p.getSaleStarting(),p.getSaleEnd(),p.getEnd());DBUtils.closeObject();return result;}}
