struts2验证框架后台验证用户注册 .

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：

User类采用hibernate的注解形式：

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;
    }

}

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;

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

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

}

DAO层的实现类为：

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);
    }

}

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：

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);
    }

}

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：
