userdaoimpl.java

实现了基本的oa功能：个人日志。。。

package oa.popedommanager.data.impl;

import java.util.List;

import oa.dailywork.model.po.Department;
import oa.popedommanager.data.dao.UserDAO;
import oa.popedommanager.model.po.Employee;

import org.hibernate.Criteria;
import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.criterion.Expression;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

public class UserDaoImpl extends HibernateDaoSupport implements UserDAO {

	public List login(String username, String password) {
		Session session = getSession();
		Criteria crt =  session.createCriteria(Employee.class);
		crt.add(Expression.eq("loginName", username));
		crt.add(Expression.eq("pwd", password));
		List list = crt.list();
		session.close();
		return list;
	}

	public Department findById(Long id) {
		Session session = this.getSession();
		Criteria criteria =  session.createCriteria(Employee.class);
		criteria.add(Expression.eq("employeeId", id));
		criteria.createCriteria("dep");
		List list = criteria.list();
		Employee e =(Employee)list.iterator().next();
		Department dep = new Department();
		dep.setDepartmentId(e.getDep().getDepartmentId());
		dep.setDepartmentName(e.getDep().getDepartmentName());
		session.close();
		return dep;
	}
