Struts2 + Spring 2.5 + Hibernate 3.2登录实例

1. 创建一个WEB工程

2. 加入Struts 2核心包

struts2-core-2.0.14.jar

commons-logging-1.0.4.jar

freemarker-2.3.8.jar

ognl-2.6.11.jar

xwork-2.0.7.jar

struts2-spring-plugin-2.0.14.jar

3. 加载Spring 2.5选择以下包

Spring 2.5 AOP Libraries

Spring 2.5 Core Libraries

Spring 2.5 Persistence Core Libraries

Spring 2.5 PersistenceJDBC Libraries

Spring 2.5 Web Libraries

选择spring配置文件存储位置为WEB-INF文件夹

4. 加载Hibernate 3.1

包全部选择

下一步 选择Existing Spring configuration file

在SessionFactory Id后 输入: sessionFactory

下一步 选择配置好的数据库连接

finish后有一个keep exting 和replace

选择replace

5.web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	
  	<!-- 配置spring的监听器 -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationContext-*.xml</param-value>
    </context-param>
    <!-- 开启监听 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

	
	<!-- Struts2 配置 -->
	
	<filter>
		<filter-name>struts2</filter-name>
		<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>struts2</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	<welcome-file-list>
    	<welcome-file>login.jsp</welcome-file>
  	</welcome-file-list>
</web-app>

6. 在src下建struts.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">

<struts>
	
	<!--导入struts-default.xml文件 -->
	<include file="struts-default.xml"></include>
	
	<!-- 配置中文支持 -->
	<constant name="struts.i18n.encoding" value="GBK"></constant>
	
	<!-- 配置Action -->
	<package name="struts" extends="struts-default" namespace="/">
		<action name="login" class="loginAction">
			<result name="success">/result.jsp</result>
			<result name="fail">/error.jsp</result>
		</action>
	</package>
	
</struts>

7. 创建数据表

create table `mytest`.`person`(
	`id` INT default '' not null,
	`uname` VARCHAR(20),
	`upwd` VARCHAR(20)
);

8. 使用工具通过Person表生成类文件和Person.hbm.xml

package com.user.vo;

public class Person  implements java.io.Serializable {

    private Integer id;
    private String uname;
    private String upwd;

    public Person() {
    }

    public Person(Integer id) {
        this.id = id;
    }
    
    public Person(Integer id, String uname, String upwd) {
        this.id = id;
        this.uname = uname;
        this.upwd = upwd;
    }
    
    public Integer getId() {
        return this.id;
    }
    
    public void setId(Integer id) {
        this.id = id;
    }

    public String getUname() {
        return this.uname;
    }
    
    public void setUname(String uname) {
        this.uname = uname;
    }

    public String getUpwd() {
        return this.upwd;
    }
    
    public void setUpwd(String upwd) {
        this.upwd = upwd;
    }

}

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">


<hibernate-mapping>
	<class name="com.user.vo.Person" table="person" catalog="mytest">
		<id name="id" type="java.lang.Integer">
			<column name="id" length="4" />
		</id>
		<property name="uname" type="java.lang.String">
			<column name="uname" length="20" />
		</property>
		<property name="upwd" type="java.lang.String">
			<column name="upwd" length="20" />
		</property>
	</class>
</hibernate-mapping>

9. 创建业务逻辑处理类

package com.user.dao;

import java.util.List;

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

import com.user.vo.Person;

public class PersonManager extends HibernateDaoSupport{
	
	public boolean isLogin(Person per){
		boolean flag = false;
		
		String hql = "From Person as p where p.uname=? and p.upwd=?";
		Query q = this.getSession().createQuery(hql);
		q.setString(0, per.getUname());
		q.setString(1, per.getUpwd());
		List all = q.list();
		
		if(all.size() > 0){
			flag = true;
		}
		else{
			flag = false;
		}
		
		return flag;
	}

}

10. 创建Action

package com.user.action;

import com.opensymphony.xwork2.ActionSupport;
import com.user.dao.PersonManager;
import com.user.vo.Person;

public class LoginAction extends ActionSupport{

	private String username;
	private String password;
	private PersonManager personManager;

	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 PersonManager getPersonManager() {
		return personManager;
	}

	public void setPersonManager(PersonManager personManager) {
		this.personManager = personManager;
	}

	@Override
	public String execute() throws Exception {
		String flag = "";

		Person per = new Person();
		per.setUname(this.username);
		per.setUpwd(this.password);
		
		if(personManager.isLogin(per)){
			flag = "success";
		}
		else{
			flag = "fail";
		}
		
		return flag;
	}
	
	

}

11. 配置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"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName"
			value="org.gjt.mm.mysql.Driver">
		</property>
		<property name="url" value="jdbc:mysql://localhost:3306/mytest"></property>
		<property name="username" value="root"></property>
		<property name="password" value="root"></property>
	</bean>
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLDialect
				</prop>
			</props>
		</property>
		<property name="mappingResources">
			<list>
				<value>com/user/vo/Person.hbm.xml</value></list>
		</property>
	</bean>
	
	<!--   配置PersonManager.java类文件 -->

	<bean id="personManager" class="com.user.dao.PersonManager" abstract="false" lazy-init="default" autowire="default" dependency-check="default">
   		<property name="sessionFactory" >
    		<ref local="sessionFactory"/>
   		</property>
	</bean>

	<!--   配置LoginAction.java类文件 -->

	<bean id="loginAction" class="com.user.action.LoginAction" >
		<property name="personManager">
           <ref bean="personManager" />
       	</property>

	</bean>
	
</beans>

12.前台页面

login.jsp

<%@ page language="java" contentType="text/HTML;charset=GBK" pageEncoding="GBK"%>

<%@ taglib prefix="s" uri="/struts-tags"%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    
  </head>
  
  <body>
    <center>
    	<s:form action="login" method="POST" namespace="/">
    		<s:textfield name="username" label="用户名" size="14"/>
    		<s:password name="password" label="密  码" size="14"/>
    		<s:submit label="提交" />
    	</s:form>
    </center>
  </body>
</html>

error.jsp

<%@ page language="java" contentType="text/HTML;charset=GBK" pageEncoding="GBK"%>

<%
	out.println("输入用误,输入的信息为" + "</br>");
	out.println("用户名: " + request.getParameter("username") + "</br>");
	out.println("密&nbsp;&nbsp;码: " + request.getParameter("password"));
 %>

result.jsp

<%@ page language="java" contentType="text/HTML;charset=GBK" pageEncoding="GBK"%>

<%
	out.println("用户名是: " + request.getParameter("username") + "</br>");
	out.println("密&nbsp;&nbsp;码是: " + request.getParameter("password"));
 %>
