<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.devMode" value="true"></constant>
<package name="test" extends="struts-default" namespace="/test">
<action name="test" class="com.boot.action.TestAction"
method="test">
<result>/jsps/main.jsp</result>
</action>
</package>
</struts>
2.hibernater主配置文件（模板）
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- 链接数据库的配置 -->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/boot</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">123456</property>
<!-- 配置数据库的方言 -->
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- 配置是否输入sql命令 -->
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">false</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- 配置C3p0连接池 -->
<property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<!-- 将Session绑定到当前线程 -->
<property name="hibernate.current_session_context_class">thread</property>
<!-- 加载实体类与数据库的映射文件 -->
<mapping resource="com/boot/domain/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>
3.实体类和数据库映射文件(模板)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- 实体类的映射文件 -->
<hibernate-mapping package="com.boot.domain">
<class name="User" table="sys_user">
<!-- id是主键字段，该标签用来指明主键的生成方式 -->
<id name="user_id" column="user_id">
<generator class="native"></generator>
</id>
<!-- property标签用来配置一般实体类属性与字段之间的映射关系 -->
<property name="user_code" column="user_code"></property>
<property name="user_name" column="user_name"></property>
<property name="user_password" column="user_password"></property>
<property name="user_state" column="user_state"></property>
</class>
</hibernate-mapping>
3.数据库创建
1.创建数据库
1.打开数据库服务
2.使用数据库可视化连接工具连接数据库
本案例使用sqlyog作为数据库连接工具和native是相同的
2.创建表
1.复制下面的sql语句

3.与base_dict对应的实体类
package com.boot.domain;
import java.io.Serializable;
/**

*/
public class BaseDict implements Serializable {
private static final long serialVersionUID = 1L;
private String dict_id; // 数据字典id

public String getDict_memo() {
return dict_memo;
}
public void setDict_memo(String dict_memo) {
this.dict_memo = dict_memo;

2.建立实体类与数据库字段联系的配置文件
名称为user.hbm.xml在com.boot.domain包下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<!-- 实体类的映射文件 -->
<hibernate-mapping package="com.boot.domain">
<class name="User" table="sys_user">
<!-- id是主键字段，该标签用来指明主键的生成方式 -->
<id name="user_id" column="user_id">
<generator class="native"></generator>
</id>
<!-- property标签用来配置一般实体类属性与字段之间的映射关系 -->
<property name="user_code" column="user_code"></property>
<property name="user_name" column="user_name"></property>
<property name="user_password" column="user_password"></property>
<property name="user_state" column="user_state"></property>
</class>
</hibernate-mapping>
3.配置hibernate
名称为hibernate.cfg.xml在src/main/java目录下
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration PUBLIC
"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory>
<!-- 链接数据库的配置 -->
<property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>
<property name="hibernate.connection.url">jdbc:mysql://localhost:3306/boot</property>
<property name="hibernate.connection.username">root</property>
<!--请自行修改自己数据库的密码-->
<property name="hibernate.connection.password">123456</property>
<!-- 配置数据库的方言 -->
<property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>
<!-- 配置是否输入sql命令 -->
<property name="hibernate.show_sql">true</property>
<property name="hibernate.format_sql">false</property>
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- 配置C3p0连接池 -->
<property name="hibernate.connection.provider_class">org.hibernate.connection.C3P0ConnectionProvider</property>
<!-- 将Session绑定到当前线程 -->
<property name="hibernate.current_session_context_class">thread</property>
<!-- 加载实体类与数据库的映射文件 -->
<mapping resource="com/boot/domain/User.hbm.xml"/>
</session-factory>
</hibernate-configuration>
4.编写hibernaete工具类
package com.boot.util;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
public class HibernateUtil {
//定义工厂
private static SessionFactory factory;
static {
try {
//创建配置类
Configuration cfg = new Configuration();
cfg.configure();// 加载默认的主配置文件
factory = cfg.buildSessionFactory();
} catch (HibernateException e) {
System.out.println(e.getMessage());
throw new ExceptionInInitializerError("初始化配置文件出错，请检查配置文件！");
}
}
//获取session对象
public static Session getCurrentSession() {
return factory.getCurrentSession();
}
}
5.编写UserDao类
package com.boot.dao;
import java.util.List;
import org.hibernate.Query;
import org.hibernate.Session;
import com.boot.domain.User;
import com.boot.util.HibernateUtil;
public class UserDao {
//向用户返回全部的user数据
public List<User> getAllUser() {
//获取session对象
Session session = HibernateUtil.getCurrentSession();
//使用HQL语句查询，需要获取Query对象
Query query = session.createQuery("from User");
//返回查到的所有数据
return (List<User>) query.list();
}
}
6.编写service层
package com.boot.service;
import java.util.List;
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;
import com.boot.dao.UserDao;
import com.boot.domain.User;
import com.boot.util.HibernateUtil;
public class UserService {
//需要用到dao层
private UserDao userDao = new UserDao();
//获取所有的用户信息
public List<User> getAllUser() {
Session session = HibernateUtil.getCurrentSession();
Transaction tx = null;
List<User> users = null;
try {
//开启事务
tx = session.beginTransaction();
users = userDao.getAllUser();
tx.commit();
return users;
}catch (HibernateException e){
if (tx != null) {
//回滚事务
tx.rollback();
}
}
//返回数据
return users;
}
}
7.编写Action层
package com.boot.action;
import java.util.List;
import org.apache.struts2.ServletActionContext;
import com.boot.domain.User;
import com.boot.service.UserService;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;
public class UserAction extends ActionSupport implements ModelDriven<User>{
//模型驱动类，用于接收前端传过来的的数据
private User user = new User();
//需要调用service层
private UserService userServcie = new UserService();
//获取所有的用户
public String getAllUser() {
//获取所有用户信息
List<User> users = userServcie.getAllUser();
//添加到request域中
ServletActionContext.getRequest().setAttribute("list", users);
//返回success
return SUCCESS;
}
@Override
public User getModel() {
// TODO Auto-generated method stub
return user;
}
}
8.配置struts
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.devMode" value="true"></constant>
<package name="user" extends="struts-default" namespace="/user">
<action name="getAllUser" class="com.boot.action.UserAction"
method="getAllUser">
<!-- 当action类返回success时跳转到该页面 -->
<result name="success">/jsps/main.jsp</result>
</action>
</package>
</struts>
9.创建数据展示页面
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" isELIgnored="false"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
${list }
</body>
</html>
10.测试
1.启动 tomcat服务器
2.访问地址
数据展示成功
用户登录功能
流程图
UserAction类添加登录方法
//登录
public String login() {
System.out.println("进入登录方法");
try {
User resultUser = userServcie.login(user);
//保存到session域中
ServletActionContext.getRequest().getSession().setAttribute("user", resultUser);
return SUCCESS;
} catch (UserException e) {
//登陆失败
ServletActionContext.getRequest().setAttribute("msg", e.getMessage());
ServletActionContext.getRequest().setAttribute("user", user);
return INPUT;
}
}
配置struts配置文件
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
"http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.devMode" value="true"></constant>
<package name="user" extends="struts-default" namespace="/user">
<!--获取所有用户请求-->
<action name="getAllUser" class="com.boot.action.UserAction" method="getAllUser">
<!-- 当action类返回success时跳转到该页面 -->
<result name="success">/jsps/main.jsp</result>
</action>
<!--用户登录请求-->
<action name="login" class="com.boot.action.UserAction" method="login">

<result name="input">/jsps/login.jsp</result>
</action>
<!--用户退出请求-->
<action name="logout" class="com.boot.action.UserAction" method="logout">
<result name="login">/jsps/login.jsp</result>
</action>
<!--用户注册请求-->
<action name="register" class="com.boot.action.UserAction" method="register">
<result name="success">/jsps/login.jsp</result>
</action>
</package>
</struts>
UserService类
//登录
public User login(User user) throws UserException{
Session session = HibernateUtil.getCurrentSession();
Transaction tx = null;
User resultUser = null;
try {
//开启事务
tx = session.beginTransaction();
//通过用户账号获取用户
resultUser = userDao.getUserByCode(user.getUser_code());
tx.commit();
//判断用户是否注册
if(resultUser == null) {
// 不存在
throw new UserException("用户未注册");
}else {
// 用户存在
if(MD5Util.md5(user.getUser_password()).equals(resultUser.getUser_password())) {
//密码相同
return resultUser;
}else {
throw new UserException("密码不正确,请重新输入！");
}
}
}catch (HibernateException e){
if (tx != null) {
//回滚事务
tx.rollback();
}
}
//返回数据
return resultUser;
}
UserDao类
//通过用户账号获取用户信息
public User getUserByCode(String user_code) {
Session session = HibernateUtil.getCurrentSession();
Query query = session.createQuery("from User where user_code = :user_code");
query.setParameter("user_code", user_code);
return (User) query.uniqueResult();
}
用户安全问题
问题
当用户注册时注册的密码，采用明文直接存入数据库中，对用户的安全有问题
可以使用加密算法，对密码进行加密
MD5加密
引入jar包
引入common-codec包
编写工具类
package com.boot.util;
import java.nio.charset.StandardCharsets;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import org.apache.commons.codec.binary.Hex;
public class MD5Util {
/**
* 将数据进行 MD5 加密，并以16进制字符串格式输出
* @param data
* @return
*/
public static String md5(String data) {
try {
MessageDigest md = MessageDigest.getInstance("MD5");
return Hex.encodeHexString(md.digest(data.getBytes(StandardCharsets.UTF_8)));
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
System.out.println("密码加密失败");
}
return "";
}
}
问题
前端异步请求获取后端返回的json数据
当前端发起请求，并且希望后端返回的json数据，当接收后把json数据转换为js对象封装到data对象里面，后执行success定义的方法，如果后端返回的不是json数据，就会调用error定义的方法
$.ajax({
url:'${pageContext.request.contextPath }/user/checkUserCode.action',
type:'POST',
data: params,
dataType:"json",
success:function (data) {
alert(data.msg)
console.log(data.msg)
},
error:function(result){
}
});
后端怎么返回json数据
详细请看这篇文章: https://blog.csdn.net/feinifi/article/details/81114268.
在读取hibernate配置文件时
因为使用的JDK为14版本，该版本中移除了该类，所以需要手动添加jar包
