SSH框架的整合

1.创建实体类,配置web.xml

package com.ch.entity;

public class User {

    private int id;        //用户编号
    private  String username;    //    用户名
    private String password;    //密码
    private String email;        //邮箱
    private String realname;    //真实姓名
    private int my_count;        //发帖数
    private int reply_count;    //回帖数
    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }
    public String getEmail() {
        return email;
    }
    public void setEmail(String email) {
        this.email = email;
    }
    public String getRealname() {
        return realname;
    }
    public void setRealname(String realname) {
        this.realname = realname;
    }
    public int getMy_count() {
        return my_count;
    }
    public void setMy_count(int my_count) {
        this.my_count = my_count;
    }
    public int getReply_count() {
        return reply_count;
    }
    public void setReply_count(int reply_count) {
        this.reply_count = reply_count;
    }
    
    
}

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"

    <!-- Spring配置 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:bean.xml</param-value>

    </listener>

    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

2.创建实体类的映射文件------命名规则：类名.hbm.xml--------User.hbm.xml

<?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">

<hibernate-mapping package="com.ch.entity">
    <!--
         name:类名
         table:对应的表
     -->
    <class name="User" table="user">
    <!--
         id:主键
         name:主键名
         column:对应的列名
     -->
        <id name="id" column="userid">
            <generator class="native"></generator>
        </id>
        <!--
         property:其他列
         name:属性名
         column:对应的列名
     -->
        <property name="username"></property>
        <property name="realname"></property>
        <property name="password"></property>
        <property name="email"></property>
        <property name="my_count"></property>
        <property name="reply_count"></property>
    </class>
    
</hibernate-mapping>

3.配置spring的配置文件bean.xml；

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
         http://www.springframework.org/schema/beans/spring-beans.xsd
          http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context.xsd
         http://www.springframework.org/schema/aop
         http://www.springframework.org/schema/aop/spring-aop.xsd
         http://www.springframework.org/schema/tx
          http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 所有配置的公共部门 -->
    
    <!-- 1. 连接池实例 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql:///chenlong1"></property>
        <property name="user" value="root"></property>
        <property name="password" value="root"></property>
        <property name="initialPoolSize" value="3"></property>
        <property name="maxPoolSize" value="6"></property>
    </bean>

    <!-- 2. SessionFactory实例创建 -->
    <!-- 所有的配置都由spring维护(项目中不再需要hibernate.cfg.xml啦) -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <!-- a. 连接池 -->
        <property name="dataSource" ref="dataSource"></property>
        
        <!-- b. hibernate常用配置： 方言、显示sql、自动建表等 -->
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="hibernate.hbm2ddl.auto">update</prop>
            </props>
        </property>
        
        <!-- c. 映射配置 -->
        <property name="mappingLocations">
            <list>
                <value>classpath:com/ch/entity/*.hbm.xml</value>
            </list>
        </property>
    </bean>
    
    
    <!-- 3. 事务配置 -->
    <!-- a. 事务管理器 -->
    <bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"></property>
    </bean>
    <!-- b. 事务增强 -->
    <tx:advice id="txAdvice" transaction-manager="txManager">
        <tx:attributes>
            <tx:method name="*" read-only="false"/>
        </tx:attributes>
    </tx:advice>
    <!-- c. AOP配置 -->
    <aop:config>
        <aop:pointcut expression="execution(* com.ch.service.*.*(..))" id="pt"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pt"/>
    </aop:config>
    
    <!-- 4.开启注解扫描 -->
    <context:component-scan base-package="com.ch"></context:component-scan>
</beans>     

4.dao层

package com.ch.dao;

import java.io.Serializable;

import javax.annotation.Resource;

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
import org.springframework.stereotype.Repository;

import com.ch.entity.User;
@Repository
public class UserDao {

    @Resource
    private SessionFactory sessionFactory;
    /**
     * 保存
     * @param user
     */
    public void save(User user) {

        //创建session
        Session session = sessionFactory.openSession();
        //开启手动提交事务
        Transaction tx=session.beginTransaction();
        try {
            //保存数据
            session.save(user);
            //提交事务
            tx.commit();
            
        } catch (Exception e) {
            //提交失败，回滚
            tx.rollback();
            e.printStackTrace();
        }finally{
            //关闭session
            session.close();
        }
        
    }
    /**
     * 登录验证
     * @param user
     * @return
     */
    public User login(User user) {
        return (User)sessionFactory.openSession().createQuery("from User where username=? and password=?")
        .setString(0, user.getUsername())
        .setString(1, user.getPassword())
        .uniqueResult();
        
    }
    /**
     * id查找
     * @param id
     * @return
     */
    public User findById(Serializable id) {
        Session session = sessionFactory.openSession();
        Transaction tx=session.beginTransaction();
        User user = (User) session.get(User.class, id);
        tx.commit();
        session.close();
        return user;
    }

}

5.service层

package com.ch.service;

import java.io.Serializable;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.ch.dao.UserDao;
import com.ch.entity.User;

@Service
public class UserService {
    @Resource
    private UserDao userDao;
    
    public User findById(Serializable id){
        return userDao.findById(id);
                
    }
    public boolean login(User user){
        if(userDao.login(user)!=null){
            System.out.println("登陆成功！");
            return true;
        }else{
            System.out.println(user.getUsername());
            System.out.println("用户名不存在");
            return false;
        }
    }
    public boolean register(User user){
        if(userDao.login(user)!=null){
            System.out.println("用户名已经重复！");
            return false;
        }else{
            user.setMy_count(0);
            user.setReply_count(0);
            userDao.save(user);
            System.out.println("注册成功");
            return true;
        }
    }
    

}

6.action控制层

package com.ch.action;

import java.sql.Driver;
import java.util.Map;

import javax.annotation.Resource;

import org.springframework.stereotype.Component;
import org.springframework.stereotype.Controller;

import com.ch.dao.UserDao;
import com.ch.entity.User;
import com.ch.service.UserService;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;

@Component
public class UserAction extends ActionSupport{
    private User user=new User();
    public void setUser(User user) {
        
        this.user = user;
    }
    
    public User getUser() {
        return user;
    }
    

    @Resource
    private UserService userService;
    @Override
    public String execute() throws Exception {
        //获取数据
        User user=userService.findById(1);
        
        ActionContext ac=ActionContext.getContext();
        //获取request
        Map<String, Object> request=ac.getContextMap();
        //将数据放入
        request.put("user", user);
        
        return "success";
    }
    public String login(){
        ActionContext ac=ActionContext.getContext();
        Map<String, Object> session=ac.getSession();
        //获取request
        Map<String, Object> request=ac.getContextMap();
        System.out.println(user.getUsername());
        if(userService.login(user)){
            session.put("username", user.getUsername());
            if(session.get("login")!=null){
                
                session.remove("login");
            }
            return "loginSuccess";
        }else {
            session.put("login", "1");
            
            return "login";
        }
        
    }
    public String register(){
        
        System.out.println(user.getUsername());
        System.out.println(user.getEmail());
        if(userService.register(user)){
            return "registerSuccess";
        }else{
            ActionContext ac=ActionContext.getContext();
            //获取request
            Map<String, Object> request=ac.getContextMap();
            //将数据放入
            request.put("user", user);
            return "register";
        }
        
        
    }
    public String list(){
        return "success";
    }
    
}

6.配置struts.xml

<?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.i18n.encoding" value="UTF-8"/>
    <package name="userConfig" extends="struts-default">
    
        
        <!-- action实例交给spring容器创建 -->
        <action name="user_*" class="userAction" method="{1}">
            <result name="loginSuccess" type="redirectAction">dictionary_list</result>
            <result name="registerSuccess">/jsp/login.jsp</result>
            <result name="register">/jsp/register.jsp</result>
            <result name="login">/jsp/login.jsp</result>
        </action>
        
    </package>

</struts>

8.jsp的创建

略；

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"xmlns:context="http://www.springframework.org/schema/context"xmlns:aop="http://www.springframework.org/schema/aop"xmlns:tx="http://www.springframework.org/schema/tx"xsi:schemaLocation="http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans.xsd      http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context.xsd         http://www.springframework.org/schema/aop         http://www.springframework.org/schema/aop/spring-aop.xsd         http://www.springframework.org/schema/tx      http://www.springframework.org/schema/tx/spring-tx.xsd">
