用seam,richfaces,ajax4jsf,spring,hibernate实践开发实例

创建实体类

package com.pojo;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;


@Entity
@Table(name = "users", catalog = "test")
public class Users implements java.io.Serializable {

	// Fields

	private Integer id;
	private String user;
	private String pwd;
	private String email;

	// Constructors

	/** default constructor */
	public Users() {
	}

	/** full constructor */
	public Users(String user, String pwd, String email) {
		this.user = user;
		this.pwd = pwd;
		this.email = email;
	}

	// Property accessors
	@Id
	@GeneratedValue
	@Column(name = "id", unique = true, nullable = false)
	public Integer getId() {
		return this.id;
	}

	public void setId(Integer id) {
		this.id = id;
	}

	@Column(name = "user", nullable = false, length = 10)
	public String getUser() {
		return this.user;
	}

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

	@Column(name = "pwd", nullable = false, length = 10)
	public String getPwd() {
		return this.pwd;
	}

	public void setPwd(String pwd) {
		this.pwd = pwd;
	}

	@Column(name = "email", nullable = false, length = 50)
	public String getEmail() {
		return this.email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

}

 

创建dao类

import java.util.List;
import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.hibernate.LockMode;
import org.springframework.context.ApplicationContext;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;



public class UsersDAO extends HibernateDaoSupport {
	private static final Log log = LogFactory.getLog(UsersDAO.class);
	// property constants
	public static final String USER = "user";
	public static final String PWD = "pwd";
	public static final String EMAIL = "email";

	protected void initDao() {
		// do nothing
	}

	public void save(Users transientInstance) {
		log.debug("saving Users instance");
		try {
			getHibernateTemplate().save(transientInstance);
			log.debug("save successful");
		} catch (RuntimeException re) {
			log.error("save failed", re);
			throw re;
		}
	}

	public void delete(Users persistentInstance) {
		log.debug("deleting Users instance");
		try {
			getHibernateTemplate().delete(persistentInstance);
			log.debug("delete successful");
		} catch (RuntimeException re) {
			log.error("delete failed", re);
			throw re;
		}
	}

	public Users findById(java.lang.Integer id) {
		log.debug("getting Users instance with id: " + id);
		try {
			Users instance = (Users) getHibernateTemplate().get(
					"com.pojo.Users", id);
			return instance;
		} catch (RuntimeException re) {
			log.error("get failed", re);
			throw re;
		}
	}

	@SuppressWarnings("unchecked")
	public List findByExample(Users instance) {
		log.debug("finding Users instance by example");
		try {
			List results = getHibernateTemplate().findByExample(instance);
			log.debug("find by example successful, result size: "
					+ results.size());
			return results;
		} catch (RuntimeException re) {
			log.error("find by example failed", re);
			throw re;
		}
	}

	@SuppressWarnings("unchecked")
	public List findByProperty(String propertyName, Object value) {
		log.debug("finding Users instance with property: " + propertyName
				+ ", value: " + value);
		try {
			String queryString = "from Users as model where model."
					+ propertyName + "= ?";
			return getHibernateTemplate().find(queryString, value);
		} catch (RuntimeException re) {
			log.error("find by property name failed", re);
			throw re;
		}
	}

	@SuppressWarnings("unchecked")
	public List findByUser(Object user) {
		return findByProperty(USER, user);
	}

	@SuppressWarnings("unchecked")
	public List findByPwd(Object pwd) {
		return findByProperty(PWD, pwd);
	}

	@SuppressWarnings("unchecked")
	public List findByEmail(Object email) {
		return findByProperty(EMAIL, email);
	}

	@SuppressWarnings("unchecked")
	public List findAll() {
		log.debug("finding all Users instances");
		try {
			String queryString = "from Users";
			return getHibernateTemplate().find(queryString);
		} catch (RuntimeException re) {
			log.error("find all failed", re);
			throw re;
		}
	}

	public Users merge(Users detachedInstance) {
		log.debug("merging Users instance");
		try {
			Users result = (Users) getHibernateTemplate().merge(
					detachedInstance);
			log.debug("merge successful");
			return result;
		} catch (RuntimeException re) {
			log.error("merge failed", re);
			throw re;
		}
	}

	public void attachDirty(Users instance) {
		log.debug("attaching dirty Users instance");
		try {
			getHibernateTemplate().saveOrUpdate(instance);
			log.debug("attach successful");
		} catch (RuntimeException re) {
			log.error("attach failed", re);
			throw re;
		}
	}

	public void attachClean(Users instance) {
		log.debug("attaching clean Users instance");
		try {
			getHibernateTemplate().lock(instance, LockMode.NONE);
			log.debug("attach successful");
		} catch (RuntimeException re) {
			log.error("attach failed", re);
			throw re;
		}
	}

	public static UsersDAO getFromApplicationContext(ApplicationContext ctx) {
		return (UsersDAO) ctx.getBean("UsersDAO");
	}
}

 

创建seam的bean控制

package com.bean;

import java.io.Serializable;
import java.util.List;

import org.jboss.seam.ScopeType;
import org.jboss.seam.annotations.Factory;
import org.jboss.seam.annotations.In;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.datamodel.DataModel;
import org.jboss.seam.annotations.datamodel.DataModelSelection;

import com.pojo.Users;
import com.pojo.UsersDAO;

@Name("userList")
@Scope(ScopeType.CONVERSATION)
public class UserList implements Serializable {

	private static final long serialVersionUID = -3803430546141700023L;

	private int scrollerPage = 1;
	
	@In("#{UsersDAO}")
	private UsersDAO usersDAO = null;
	
	@DataModel
	private List<Users> users = null;
	
	@DataModelSelection
	private Users u;
	
	@Factory("users")
	public void init(){
		this.users = usersDAO.findAll();
	}
	
	public void resetpwd(){
		this.u.setPwd("kenter@grace");
		this.usersDAO.save(this.u);
	}
	
	public void delete(){
		this.usersDAO.delete(this.u);
	}

	public void setScrollerPage(int scrollerPage) {
		this.scrollerPage = scrollerPage;
	}

	public int getScrollerPage() {
		return scrollerPage;
	}
}

 

创建页面

然后运行工程预览
