物资管理系统

一：首先连接数据库

package util;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class JDBUtil {
public static String url="jdbc:mysql://localhost:3306/test?useSSl=false";
public static String user="root";
public static String password="root";
public static Connection getConn() {
    Connection conn=null;
    try {
        Class.forName("com.mysql.jdbc.Driver");//加载驱动
        conn = DriverManager.getConnection(url, user, password);
    } catch (Exception e) {
        // TODO: handle exception
        e.printStackTrace();
    }
    
    
    return conn;
}
//
public static void close(Statement state,Connection conn) {
    
    if(state!=null) {
        try {
            state.close();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    if(conn!=null) {
        try {
            conn.close();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    
    
}


public static void close(ResultSet rs,Statement state,Connection conn) {
    if(rs!=null) {
        try {
            rs.close();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
    }
    if(state!=null) {
        try {
            state.close();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    if(conn!=null) {
        try {
            conn.close();
        } catch (SQLException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        
    }
}

}
