spring和hibernate的一个整合

整合的这个小案例是采用贫血模式设计的。

com.huxin.patternenemia.domain

package com.huxin.patternenemia.domain;import java.util.Set;public class User {/* *  user_id int(3) primary key,        user_name varchar(10),         user_password varchar(20) */private  int userId;private String userName;private String password;private Set News;public int getUserId() {return userId;}public void setUserId(int userId) {this.userId = userId;}public String getUserName() {return userName;}public void setUserName(String userName) {this.userName = userName;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}public Set getNews() {return News;}public void setNews(Set news) {News = news;}}
