首先要对SQL server的一些配置进行更改:
找到SQL server的配置管理器:然后点击进去。
找到SQL server网络配置下一级的mssqlserver的协议。把右边的,TCP/Ip的状态右击改为启动。
也可以点击属性设置,找到ip地址
把常用的ip10/ip6/ip4的地址改为本机。127.0.0.1 不能改成localhost
改完这些之后,重启SQL server服务 sqlserver(mssqlserver)
新建一个类:
- public class SqlServerUtils {
- public static Connection con = null;
- public static Statement state = null;
- public static ResultSet rs = null;
-
- static {
- try {
- Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
- } catch (ClassNotFoundException e) {
- e.printStackTrace();
- }
- }
- //连接数据库
- public static Connection getCon(){
- String url = "jdbc:sqlserver://localhost:1433;databaseName=meitao";
- //databaseName = 你要连接的数据库名字
- String username = "sa"; //要连接的用户名
- String password = "123"; //密码
- try {
- con = DriverManager.getConnection(url,username,password);
- } catch (SQLException throwables) {
- throwables.printStackTrace();
- }
- return con;
- }
- //关闭连接
- public static void close(Connection con,Statement state,ResultSet rs){
- try {
- if (rs != null){
- rs.close();
- }
- if (state != null){
- state.close();
- }
- if (con != null){
- con.close();;
- }
- }catch (Exception e){
- e.printStackTrace();
- }
- }
- }

新建dao层完成增删改查以adminDao为例:
- public class AdminDao {
-
- //添加admin
- public Integer addAdmin(Admin admin){
- Connection con = SqlServerUtils.getCon();
- PreparedStatement ps = null;
- Integer result = null;
- String sql = "insert into admin values(?,?,?)";
- try {
- ps = con.prepareStatement(sql);
- //设置问号的值
- ps.setInt(1,admin.getAdminId());
- ps.setString(2,admin.getAdminName());
- ps.setString(3,admin.getPwd());
- //执行sql语句
- int rows = ps.executeUpdate();
- if (rows > 0){
- return rows;
- }else {
- return 0;
- }
- } catch (SQLException throwables) {
- throwables.printStackTrace();
- }finally {
- SqlServerUtils.close(con,ps,null);
- }
- return 0;
- }
-
- //删除
- public Integer delAdminById(Integer id){
- Connection con = SqlServerUtils.getCon();
- PreparedStatement ps = null;
- ResultSet rs = null;
- String sql = "delete from admin where adminid = ? ";
- try {
- ps = con.prepareStatement(sql);
- ps.setInt(1,id);
- int rows = ps.executeUpdate();
- if (rows > 0){
- System.out.println("删除成功");
- }else {
- System.out.println("删除失败");
- }
- } catch (SQLException throwables) {
- throwables.printStackTrace();
- }finally {
- SqlServerUtils.close(con,ps,null);
- }
-
-
- //查找admin
- public Admin getAdminByNameAndPwd(String name,String password){
- Connection con = SqlServerUtils.getCon();
- PreparedStatement ps = null;
- ResultSet rs = null;
- //String sql = "select * from admin where adminid = '"+id+"'";
- String sql = "select * from admin where adminname = ? and password = ?";
- try {
- ps = con.prepareStatement(sql);
- ps.setString(1,name);
- ps.setString(2,password);
- rs = ps.executeQuery();
- if (rs.next()){
- int adminId = rs.getInt(1);
- String adminName = rs.getString(2);
- String pwd = rs.getString(3);
- return new Admin(adminId,adminName,pwd);
- }
- } catch (SQLException throwables) {
- throwables.printStackTrace();
- }finally {
- SqlServerUtils.close(con,ps,rs);
- }
- return null;
- }
-
- //查询全部
- public List<Admin> getAdminList(){
- Connection con = SqlServerUtils.getCon();
- PreparedStatement ps = null;
- ResultSet rs = null;
- String sql = "select * from admin";
- try {
- ps = con.prepareStatement(sql);
- rs = ps.executeQuery();
- while (rs.next()){
- int adminId = rs.getInt("adminid");
- String adminName = rs.getString("adminName");
- String pwd = rs.getString("password");
- System.out.println("编号:"+adminId+" 姓名:"+adminName+" 密码:"+pwd);
- }
- } catch (SQLException throwables) {
- throwables.printStackTrace();
- }finally {
- SqlServerUtils.close(con,ps,rs);
- }
- return null;
- }
-
- //修改admin
- public Integer updateAdmin(Admin admin){
- Connection con = SqlServerUtils.getCon();
- PreparedStatement ps = null;
- Integer result = null;
- String sql = "update admin set adminname = ? , password = ? where adminid = ?";
- try {
- ps = con.prepareStatement(sql);
- ps.setString(1,admin.getAdminName());
- ps.setString(2,admin.getPwd());
- ps.setInt(3,admin.getAdminId());
- result = ps.executeUpdate();
- } catch (SQLException throwables) {
- throwables.printStackTrace();
- }finally {
- SqlServerUtils.close(con,ps,null);
- }
- return result;
- }
- }

新建测试类进行测试:
- public class sqlServiceTest {
- public static void main(String[] args) {
- //getAll();
- // Admin admin = new Admin(3,"里哈哈","133232");
- // updateAdmin(admin);
- //getAdminByNameAndPwd("孙道恩","111");
- delById(3);
- }
-
- //添加数据
- public static void addAdmin(){
- Admin admin = new Admin(3,"浮动","8989");
- AdminDao adminDao = new AdminDao();
- Integer rows = adminDao.addAdmin(admin);
- if (rows > 0){
- System.out.println("添加成功");
- }else {
- System.out.println("添加失败");
- }
- }
-
- //单个查询
- public static void getAdminByNameAndPwd(String name,String pwd){
- AdminDao adminDao = new AdminDao();
- Admin adminByNameAndPwd = adminDao.getAdminByNameAndPwd(name, pwd);
- System.out.println(adminByNameAndPwd);
- }
-
- //查询全部
- public static void getAll(){
- AdminDao adminDao = new AdminDao();
- List<Admin> adminList = adminDao.getAdminList();
- }
- //修改信息
- public static void updateAdmin(Admin admin){
- Integer rows = new AdminDao().updateAdmin(admin);
- if (rows > 0){
- System.out.println("修改成功");
- }else {
- System.out.println("修改失败");
- }
- }
- //根据id删除
- public static void delById(Integer id){
- AdminDao adminDao = new AdminDao();
- adminDao.delAdminById(id);
- }
- }

- import java.sql.Connection;
- import java.sql.DriverManager;
- import java.sql.SQLException;
-
- public class OracleUtils{
- public static final String URL = "jdbc:oracle:thin:@127.0.0.1:1521/PDBORCL";
- //后面的PDBORCl是要操作的pdb
- //在navicate里面使用select name,open_mode from v$pdbs;查询全部找到这个pdb
- //然后在执行下面的语句让此pdb打开alter pluggable database PDBORCL open;
- public static final String USER = "c##sde2";
- public static final String PASSWORD = "orcl";
-
- public static Connection getConnection(){

- }
- System.out.println("连接成功");
- return conn;
- }
- }
