SSH2 整合登录

此次整合的版本是：struts2.1.8 + spring2.5.6 + hibernate3.3.2

一.先整合hibernate和spring：

hibernate所需要jar包：antlr-2.7.6.jar、commons-collections-3.1.jar、dom4j-1.6.1.jar、hibernate3.jar、javassist-3.9.0.GA.jar、jta-1.1.jar、slf4j-api-1.5.8.jar、log4j.jar、slf4j-log4j12-1.5.8.jar （slf4j接口以log4j形式实现），因为采用了注解的方式所以还需(annotation3.4的包)：ejb3-persistence.jar、hibernate-annotations.jar、hibernate-commons-annotations.jar、hibernate-entitymanager.jar
，采用了c3p0连接池，还需要：c3p0-0.9.1.2.jar

spring所需要jar包：spring.jar、commons-logging.jar ，spring注解需要：common-annotations.jar ，aop需要：aspectjrt.jar、aspectjweaver.jar、cglib-nodep-2.1_3.jar

hibernate.cfg.xml配置：

Xml代码

<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC

</session-factory>

</hibernate-configuration>

applicationContext.xml配置如下：

Xml代码

<?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"

<context:component-scan base-package="com.fsj" /><!-- 启用自动扫描 -->
<!-- 基于hibernate注解的sessionFactory -->
<bean id="sessionFactory"

<!-- 基于hibernate的事务管理器 -->

<property name="sessionFactory" ref="sessionFactory" />
</bean>
<!-- 采用注解形式的声明式事务管理 -->
<tx:annotation-driven transaction-manager="txManager"/>

</beans>

User类采用hibernate的注解形式：

Java代码

package com.fsj.model;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import static javax.persistence.GenerationType.IDENTITY;
import javax.persistence.Id;
import javax.persistence.Table;

@Entity
@Table(name = "_user")
public class User implements java.io.Serializable {

private static final long serialVersionUID = -3564872478826196506L;
private Integer uid;
private String uname;
private String upwd;

@Id
@GeneratedValue(strategy = IDENTITY)
@Column(name = "u_id", unique = true, nullable = false)
public Integer getUid() {
return this.uid;
}

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

@Column(name = "u_name", length = 20)
public String getUname() {
return this.uname;
}

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

@Column(name = "u_pwd", length = 20)
public String getUpwd() {
return this.upwd;
}

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

}

DAO层的实现类为：

Java代码

package com.fsj.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.SessionFactory;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;

import com.fsj.dao.UserDao;
import com.fsj.model.User;

@Repository("userDao")
public class UserDaoImpl implements UserDao {

private HibernateTemplate hibernateTemplate;

@Resource
public void setSessionFactory(SessionFactory sessionFactory)
{
this.hibernateTemplate = new HibernateTemplate(sessionFactory);
}
@SuppressWarnings("unchecked")
public User login(String name, String pwd) {
List<User> users= hibernateTemplate.find("from User where uname=? and upwd=?",new Object[]{name,pwd});
System.out.println(users.size()+"-------------");
return (users==null || users.size()==0)?null:(User)users.get(0);
}

}

service层的实现类采用事务管理：

Java代码

package com.fsj.sevice.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.fsj.dao.UserDao;
import com.fsj.model.User;
import com.fsj.sevice.UserService;

@Service("userService")
@Transactional(rollbackFor = Exception.class)
public class UserServiceImpl implements UserService {

@Resource
private UserDao userDao;
@Transactional(readOnly = true, propagation = Propagation.NOT_SUPPORTED)
public User login(String name, String pwd) {
return userDao.login(name, pwd);
}

}

junit测试成功后，再加入struts2：

加入包：xwork-core-2.1.6.jar、struts2-core-2.1.8.jar、ognl-2.7.3.jar、freemarker-2.3.15.jar、commons-io-1.3.2.jar、commons-fileupload-1.2.1.jar、struts2-spring-plugin-2.1.8.jar

web.xml如下设置：

Xml代码

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"

struts.xml如下：

Xml代码

<?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">

<result name="success">/WEB-INF/user/loginSuccess.jsp</result>
<result name="input">/login.jsp</result>
</action>
</package>

</struts>

UserAction类：

Java代码

package com.fsj.web;

import java.util.Map;

import javax.annotation.Resource;

import org.apache.struts2.interceptor.SessionAware;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.fsj.model.User;
import com.fsj.sevice.UserService;
import com.opensymphony.xwork2.ActionSupport;
@Controller("userAction")@Scope("prototype")
public class UserAction extends ActionSupport implements SessionAware{

private Map<String, Object> session;
private User user;
@Resource
private UserService userService;

public String getResult() {
return result;
}

public String login()
{
User logindUser = userService.login(user.getUname(), user.getUpwd());
if(logindUser==null)
{
addActionError("用户名或密码错误，请重新输入。");
return INPUT;
}
session.put("user", logindUser);
return SUCCESS;
}

public User getUser() {
return user;
}

public void setUser(User user) {
this.user = user;
}

public void setSession(Map<String, Object> session) {
this.session = session;
}
}

与UserAction同一包中建立验证文件：UserAction-validation.xml

Xml代码

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
"-//OpenSymphony Group//XWork Validator 1.0.2//EN"
