- 當數據庫配置完以後我們開始idea，創建一個Maven Webapp模板項目
- 然後開始配置Tomcat服務器
- 在pom.xml中導入項目依賴的jar包

- 然後編寫數據庫連接用的文件
點擊文件後綴為.properties
driver=com.mysql.cj.jdbc.Driver
url=jdbc:mysql://localhost:3306/數據庫名字?useUnicode=true&characterEncoding=utf8
username=賬號
password=密碼
-
idea連接數據庫（不在此展示，自行解決）
-
編寫過濾器，使我們網頁每次都用utf-8編碼
點擊過濾器代碼
import javax.servlet.*;
import java.io.IOException;
public class Filter implements javax.servlet.Filter {
public void init(FilterConfig filterConfig) throws ServletException {
}
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
request.setCharacterEncoding("utf-8");
response.setCharacterEncoding("utf-8");
chain.doFilter(request,response);
}
public void destroy() {
}
}
- 編寫數據庫的公共類，實現增刪改查SRUD功能
package com.meteor.dao;
import java.io.IOException;
import java.io.InputStream;
import java.sql.*;
import java.util.Properties;
//操作數據庫的公共類
public class BaseDao {
private static final String driver;
private static final String url;
private static final String username;
private static final String password;
//靜態代碼塊，隨着類的加載而加載
static{
Properties properties = new Properties();//可以讓文件內容以鍵值對的形式讀取
//將文件內容讀出
InputStream is = BaseDao.class.getClassLoader().getResourceAsStream("db.properties");
try {
//properties.load()從輸入位元組流讀取屬性列表（鍵和元素對）。
properties.load(is);
} catch (IOException e) {
e.printStackTrace();
}
driver = properties.getProperty("driver");
url = properties.getProperty("url");
username = properties.getProperty("username");
password = properties.getProperty("password");
}
//獲取數據庫的連接
public static Connection getConnection() {
Connection connection = null;
try {
Class.forName(driver);//加載驅動
//嘗試建立與給定數據庫URL的連接。
connection = DriverManager.getConnection(url, username, password);
} catch (Exception e) {
e.printStackTrace();
}
return connection;
}
//編寫查詢公共方法
public static ResultSet execute(Connection connection,String sql,Object[] params,ResultSet resultSet,PreparedStatement preparedStatement) throws SQLException {
//connection.prepareStatement(sql)創建一個 PreparedStatement對象，用於將參數化的SQL語句發送到數據庫。
preparedStatement = connection.prepareStatement(sql);
for (int i = 0; i < params.length; i++) {
preparedStatement.setObject(i+1,params[i]);//使用給定對象設置指定參數的值。
}
resultSet = preparedStatement.executeQuery();//返回查詢結果
return resultSet;
}
//編寫增刪改公共方法
public static int execute(Connection connection,String sql,Object[] params,PreparedStatement preparedStatement) throws SQLException {
//connection.prepareStatement(sql)創建一個 PreparedStatement對象，用於將參數化的SQL語句發送到數據庫。
preparedStatement = connection.prepareStatement(sql);
for (int i = 0; i < params.length; i++) {
preparedStatement.setObject(i+1,params[i]);
}
int updateRows = preparedStatement.executeUpdate();
return updateRows;
}
//釋放資源
public static boolean closeResource(Connection connection,PreparedStatement preparedStatement,ResultSet resultSet) {
boolean flag = true;
if(resultSet != null) {
try {
resultSet.close();
//GC回收機制，如果對象為null，就會被回收。
resultSet = null;
} catch (SQLException e) {
e.printStackTrace();
flag = false;
}
}
if(preparedStatement != null) {
try {
preparedStatement.close();
//GC回收機制，如果對象為null，就會被回收。
preparedStatement = null;
} catch (SQLException e) {
e.printStackTrace();
flag = false;
}
}
if(connection != null) {
try {
connection.close();
//GC回收機制，如果對象為null，就會被回收。
connection = null;
} catch (SQLException e) {
e.printStackTrace();
flag = false;
}
}
return flag;
}
}
- 編寫service服務層代碼，驗證登錄是否正確
import dao.BaseDao;
import dao.user.UserDao;
import dao.user.UserDaoImpl;
import pojo.User;
import java.sql.Connection;
public class UserServiceImpl implements UserService{
public User login(String userCode, String password) {
UserDaoImpl userDao = new UserDaoImpl();
Connection connection = BaseDao.getConnection();//連接數據庫
User user = userDao.getLoginUser(connection, userCode);//獲得登錄用戶信息
//對登錄的用戶賬號密碼進行判斷
if(user.getUserPassword() == null ? password == null : user.getUserPassword().equals(password)) {
BaseDao.closeResource(connection,null,null);
return user;
}else {
BaseDao.closeResource(connection,null,null);
System.out.println("密碼錯誤");
return null;
}
}
}
7.編寫servlet業務層代碼，和前端交互
package com.meteor.servlet.user;
import com.meteor.pojo.User;
import com.meteor.service.user.UserService;
import com.meteor.service.user.UserServiceImpl;
import com.meteor.util.Constants;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
public class LoginServlet extends HttpServlet {
//控制層調用業務層代碼
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
System.out.println("別出bug");
//獲取前端輸入的用戶名和密碼
String userCode = req.getParameter("userCode");
String userPassword = req.getParameter("userPassword");
//和數據庫的用戶密碼對比，調用業務層
UserServiceImpl userService = new UserServiceImpl();
User user = userService.login(userCode, userPassword);
if(user != null) { //查有此人
//將用戶信息放到session中
req.getSession().setAttribute(Constants.USER_SESSION,user);
//登錄成功，跳轉到內部主頁
resp.sendRedirect("jsp/frame.jsp");
}else {
//查無此人，轉回登錄頁面
req.setAttribute("error","用戶密碼不正確");
req.getRequestDispatcher("login.jsp").forward(req,resp);
}
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
doGet(req, resp);
}
}
- 工具類用來存放session值
點擊查看代碼
public class Constants {
public static final String USER_SESSION = "userSession";
}
- 在web.xml設置servlet和filter過濾器
<!-- 字符編碼過濾器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>com.meteor.filter.CharacterEncodingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 設置歡迎頁面 -->
<welcome-file-list>
<welcome-file>login.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>LoginServlet</servlet-name>
<servlet-class>com.meteor.servlet.user.LoginServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>LoginServlet</servlet-name>
<url-pattern>/login.do</url-pattern>
</servlet-mapping>
三、總結
- 前端代碼頁面都是cpoy的，若想獲取前端代碼可私信我。
- 對於smdms登錄內容就總結這麼多，也是跟着狂神學的，代碼也沒怎麼改進，只是想自己複習理解一遍。如果有不足之處，希望大家多多包涵，多多支持。如果有不懂的地方可以直接私信問我，歡迎來訪！
- 我將會繼續更新關於Java的學習知識，以及此項目的後續功能，感興趣的小夥伴可以關注一下。
- 文章寫得比較走心，用了很長時間，絕對不是copy過來的！
- 尊重每一位學習知識的人，同時也尊重每一位分享知識的人。
