轻松搭建Struts2、Spring和Hibernate框架

2017-10-13 14:34 387 查看

环境搭建是基于Myeclipse10和Mysql。

一、创建表结构user

DROP TABLE IF EXISTS `user`;

CREATE TABLE `user` (

`uid` int(11) NOT NULL AUTO_INCREMENT,

`username` varchar(255) DEFAULT NULL,

`password` varchar(255) DEFAULT NULL,

PRIMARY KEY (`uid`)

) ENGINE=InnoDB AUTO_INCREMENT=9 DEFAULT CHARSET=utf8;

二、创建web project、对应的package和在WEB-INF目录的lib下面导入相应的架包:

注：Struts2、Spring和Hibernate对应的架包网上可以去下载。

src目录下创建com.zy.user.action、com.zy.user.vo、com.zy.user.service和com.zy.user.dao

三、在步骤二的包下面分别创建:

com.zy.user.action

UserAction.java

com.zy.user.vo

User.java、User.hbm.xml映射文件

com.zy.user.service

UserService.java

com.zy.user.dao

UserDao.java

四、在src目录下面新建log4j.properties(输出日志配置文件)、jdbc.properties配置文件(数据库配置文件)。

log4j.properties:

### direct log messages to stdout ###

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.Target=System.out

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.appender.stdout.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### direct messages to file mylog.log ###

log4j.appender.file=org.apache.log4j.FileAppender

log4j.appender.file.File=c:/mylog.log

log4j.appender.file.layout=org.apache.log4j.PatternLayout

log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n

### set log levels - for more verbose logging change 'info' to 'debug' ###

log4j.rootLogger=info, stdout

jdbc.properties:

jdbc.driver=com.mysql.jdbc.Driver

jdbc.url=jdbc\:mysql\://localhost\:3306/zyShop?useUnicode\=true&characterEncoding\=UTF-8&zeroDateTimeBehavior\=convertToNull

jdbc.user=root

jdbc.password=zhenyao

五、在WebRoot目录下创建login.jsp和index.jsp文件

login.jsp:

<s:actionerror />

<form id="loginForm"
action="${ pageContext.request.contextPath }/user_login.action"
method="post">
<table>
<tbody>
<tr>
<th>用户名:</th>
<td><input type="text" id="username" name="username"
class="text" maxlength="20">
</td>
</tr>
<tr>
<th>密码:</th>
<td><input type="password" id="password" name="password"
class="text" maxlength="20" autocomplete="off">
</td>
</tr>
<tr>
<th> </th>
<td><input type="submit" class="submit" value="登录">
</td>
</tr>
</tbody>
</table>
</form>

index.jsp:

<body>
登录成功！

</body>

五、在src目录下创建struts.xml和applicationContext.xml文件

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>
<package name="zyShop" extends="struts-default" namespace="/">

<action name="user_*" class="userAction" method="{1}">
<result name="login">/login.jsp</result>
<result name="loginSuccess" type="redirectAction">index</result>
</action>
</package>

</struts>

applicationContext.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: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"> 
<context:property-placeholder location="classpath:jdbc.properties"></context:property-placeholder>

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>
</bean>

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="dataSource" ref="dataSource"></property>

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>com/zy/shop/user/vo/User.hbm.xml</value>
</list>
</property>
</bean>


<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

<tx:annotation-driven transaction-manager="transactionManager" />

<bean id="userAction" class="com.zy.shop.user.action.UserAction"
scope="prototype">

<property name="userService" ref="userService"></property>
</bean>

<bean id="userService" class="com.zy.shop.user.service.UserService">

<property name="userDao" ref="userDao"></property>
</bean>

<bean id="userDao" class="com.zy.shop.user.dao.UserDao">

<property name="sessionFactory" ref="sessionFactory"></property>
</bean>

</beans>

六、完成User.java、User.hbm.xml、UserAction.java、UserService.java、UserDao.java

User.java:

package com.zy.shop.user.vo;

/**

* 用户实体类

*

* @author Luopeng

*

*/

public class User {
private Integer uid;
private String username;
private String password;

public Integer getUid() {
return uid;
}

public void setUid(Integer uid) {
this.uid = uid;
}

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;
}

}

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>
<class name="com.zy.shop.user.vo.User" table="user">
<id name="uid">
<generator class="native"></generator>
</id>
<property name="username" />
<property name="password" />
</class>

</hibernate-mapping>

UserDao.java:

package com.zy.shop.user.dao;

import java.util.List;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import com.zy.shop.user.vo.User;

public class UserDao extends HibernateDaoSupport {
// 用户登录的方法
public User login(User user) {
String hql = "from User u where u.username=? and u.password = ? and u.state = ? ";
@SuppressWarnings("unchecked")
List<User> list = this.getHibernateTemplate().find(hql,
user.getUsername(), user.getPassword(), 1);
if (list != null && list.size() > 0) {
return list.get(0);
} else {
return null;
}
}

}

UserService.java:

package com.zy.shop.user.service;

import org.springframework.transaction.annotation.Transactional;

import com.zy.shop.user.dao.UserDao;

import com.zy.shop.user.vo.User;

@Transactional

public class UserService {
private UserDao userDao;

public UserDao getUserDao() {
return userDao;
}

public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}

// 用户登录的方法
public User login(User user) {
return userDao.login(user);
}

}

UserAction.java:

package com.zy.shop.user.action;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;

import com.opensymphony.xwork2.ModelDriven;

import com.zy.shop.user.service.UserService;

import com.zy.shop.user.vo.User;

public class UserAction extends ActionSupport implements ModelDriven<User> {
/**
*
*/
private static final long serialVersionUID = -9141000938554518670L;

private User user = new User();

// 注入UserService
private UserService userService;

public UserService getUserService() {
return userService;
}

public void setUserService(UserService userService) {
this.userService = userService;
}

// 用户登录的方法
public String login() {
User existUser = userService.login(user);
if (existUser != null) {
// 登录成功
ServletActionContext.getRequest().getSession()
.setAttribute("existUser", existUser);
return "loginSuccess";
} else {
// 登录失败
this.addActionError("登录失败：用户名或密码不正确，或者是用户名没有激活！");
return LOGIN;
}
}

public User getModel() {
// TODO Auto-generated method stub
return user;
}

}

七、配置web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
version="2.5"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <display-name>zyShop</display-name>

<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<listener>
<description>Spring Listener</description>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
<description>Spring Listener</description>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

</web-app>

八、部署项目到Tomcat服务器，在浏览器地址栏中输入http://localhost:8080/zyShop/login.jsp

至此，框架搭建完成！如有疑问，请回复！
