《Struts2+Spring4+hibernate3》

工程结构

导入相关jar包：自行网上百度即可，根据环境需要

写dao类 以及实现

package com.icommon.dao;

import java.awt.HeadlessException;
import java.util.List;

import org.hibernate.HibernateException;

public interface BaseDao {

	public void saveObject(Object obj) throws HibernateException; 

    public List login(String name,String pwd) throws HibernateException;

    public List getAllRecord(Object obj) throws HibernateException;

    public void delete(Object obj) throws HibernateException;

    public void update(Object obj) throws HibernateException;
}

实现：

package com.icommon.dao;

import java.util.List;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.Transaction;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class UserDao extends HibernateDaoSupport implements BaseDao {

	@Override
	public void saveObject(Object obj) throws HibernateException {
		getHibernateTemplate().save(obj);
	}

	@Override
	public List login(String name,String pwd) throws HibernateException {
		List result = null;
		System.out.println("Userdao执行了");
		Object[] values = new String[]{name, pwd};
		String sql="from Employee e where e.empName=? and e.password=?";
		result = getHibernateTemplate().find(sql, values);
		System.out.println("Userdao执行了1"+result);
		return result;
	}

	@Override
	public List getAllRecord(Object obj) throws HibernateException {
		List result = null;
		System.out.println("Userdao执行了1"+obj);
		String sql = "from " +obj;
		System.out.println("sql="+sql);
		result = getHibernateTemplate().find(sql);
		System.out.println(result);
		return result;
	}

	@Override
	public void delete(Object obj) throws HibernateException {
			getHibernateTemplate().delete(obj);
	}

	@Override
	public void update(Object obj) throws HibernateException {
		getHibernateTemplate().update(obj);

	}

}

service以及实现

package com.icommon.service;

import java.util.List;

public interface UserManager {

	 public void regUser(Object obj); 

	 public List login(String name,String pwd);

	 public List getallRecord(Object obj);

	 public void delete(Object obj);

	 public void update(Object obj);
}

实现

package com.icommon.serviceimpl;

import java.util.List;

import org.hibernate.HibernateException;
import org.springframework.stereotype.Service;

import com.icommon.dao.BaseDao;
import com.icommon.dao.UserDao;
import com.icommon.service.UserManager;

@Service
public class UserManagerImpl implements UserManager {

    private BaseDao baseDao;  

	public BaseDao getBaseDao() {
		return baseDao;
	}

	public void setBaseDao(BaseDao baseDao) {
		this.baseDao = baseDao;
	}

	public UserManagerImpl() {
		baseDao = new UserDao();
     }

	@Override
	public void regUser(Object obj) throws HibernateException{

		baseDao.saveObject(obj);

	}

	@Override
	public List login(String name,String pwd) {
		System.out.println("name="+name+"pws="+pwd);
		return baseDao.login(name,pwd);

	}

	@Override
	public List getallRecord(Object obj) {
		System.out.println("Object"+obj);
		return baseDao.getAllRecord(obj);
	}

	@Override
	public void delete(Object obj) {
		baseDao.delete(obj);			

	}

	@Override
	public void update(Object obj) {
		baseDao.update(obj);

	}

}

action

package com.icommon.action;

import java.lang.ProcessBuilder.Redirect;

import com.icommon.base.Employee;
import com.icommon.service.UserManager;
import com.opensymphony.xwork2.ActionSupport;

public class EmployeeAction extends ActionSupport{

完成了一些简单的封装，要开发新功能只需在action  hibernate映射文件，struts.xml applicationcontext.xml文件编写代码即可 调用公共组件可完成增删改查，功能不完善 需要什么公共自行添加即可

页面见到就不列出，自行设计
