反射機制做的框架 跟數據庫連接啦

跟數據庫的字段相匹配：
package com.simple.entity;
public class UserInfo {
 private int id;
 private String name;
 private String password;
 public UserInfo() {
 }
 public UserInfo(String name, String password) {
  super();
  this.name = name;
  this.password = password;
 }
 public UserInfo(int id, String name, String password) {
  super();
  this.id = id;
  this.name = name;
  this.password = password;
 }
 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 String getPassword() {
  return password;
 }
 public void setPassword(String password) {
  this.password = password;
 }
}

連接數據庫的代碼：
package com.simple.hibernate;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBUtil {
 
 public static Connection getConnection(){
  try {
   Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
   return DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=test","sa","");
  } catch (ClassNotFoundException e) {
   e.printStackTrace();
   return null;
  } catch (SQLException e) {
   e.printStackTrace();
   return null;
  }
 }
 
 public static void close(Connection con){
  try {
   if(con!=null&&!con.isClosed()){
    con.close();
   }
  } catch (SQLException e) {
   e.printStackTrace();
  }
 }

}

反射機制做的框架 對於數據庫做增、刪、改、查
package com.simple.hibernate;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class DBUtil {
 
 public static Connection getConnection(){
  try {
   Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
   return DriverManager.getConnection("jdbc:sqlserver://localhost:1433;databaseName=test","sa","");
  } catch (ClassNotFoundException e) {
   e.printStackTrace();
   return null;
  } catch (SQLException e) {
   e.printStackTrace();
   return null;
  }
 }
 
 public static void close(Connection con){
  try {
   if(con!=null&&!con.isClosed()){
    con.close();
   }
  } catch (SQLException e) {
   e.printStackTrace();
  }
 }
