Spring2.5.3+Hibernate3.2+Struts2.0.11整合
只有Struts2基礎(chǔ)（初學(xué)Hibernate/Spring第三天就想著整合），有些地方不是很懂，看了網(wǎng)上大部分的例子、blog，百分百的MyEclipse插件，本人不太習(xí)慣使用MyEclipse，主要是Eclipse使用的時(shí)間比較長(zhǎng)，使用MyEclipse6.0.1時(shí)（第一次用）比如你要輸入.getHibernateTemplate()時(shí)，輸入點(diǎn)時(shí)就有提示，但是當(dāng)我輸入點(diǎn)后面的字母出錯(cuò)時(shí)，只能返回到輸入點(diǎn)之前才按點(diǎn)“.”可以提示，按ALT+/也不會(huì)出現(xiàn)，是不是我不知道快捷鍵，或是其它的方式，總之我在Eclipse中輸入一半錯(cuò)誤時(shí)按ALT+/可以又出來(lái)提示，雖然不是特依賴提示功能，但是用起來(lái)還是不爽，畢竟每天都在使用它，哪位要是知道的話煩請(qǐng)告訴一聲bulktree@126.com。
僅僅看了兩天的官方文檔就寫(xiě)了這個(gè)整合的新聞發(fā)布系統(tǒng)，感覺(jué)蠻好的，是個(gè)好的開(kāi)始 come on!
以下是一個(gè)新聞發(fā)布系統(tǒng)的登錄模塊：（兩天看文檔，一夜寫(xiě)成的，不是很完善，僅僅實(shí)現(xiàn)基本的增刪查改功能，主要是整合練習(xí)）
首先配置三個(gè)框架，有人說(shuō)要是使用MyEclipse自動(dòng)生成會(huì)有順序Spring->Hibernate->Struts,太依賴工具不是本人的習(xí)慣，這些是后話。

項(xiàng)目中我使用的是Tomcat數(shù)據(jù)源配置如下，如果你不使用Tomcat數(shù)據(jù)源也可以在下面的配置文件中配置：
|
<Context docBase="news-SSH2"
path="/news-SSH2" reloadable="true" source="org.eclipse.jst.jee.server:news-SSH2">
<Resource auth="Container"
driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30"
maxWait="10000" name="jdbc/news" password="1234" type="javax.sql.DataSource"
url="jdbc:mysql://localhost:3306/news?autoReconnect=true"
username="root"/>
</Context>
|
也在在配置applicationContext.xml文件中配置數(shù)據(jù)源
|
<!-- 定義數(shù)據(jù)源Bean，使用C3P0數(shù)據(jù)源實(shí)現(xiàn) -->
<bean id="dataSource"
class="com.mchange.v2.c3p0.ComboPooledDataSource"
destroy-method="close">
<!-- 指定連接數(shù)據(jù)庫(kù)的驅(qū)動(dòng) -->
<property name="driverClass"
value="com.mysql.jdbc.Driver"/>
<!-- 指定連接數(shù)據(jù)庫(kù)的URL -->
<property name="jdbcUrl"
value="jdbc:mysql://localhost:3306/news"/>
<!-- 指定連接數(shù)據(jù)庫(kù)的用戶名 -->
<property name="user"
value="root"/>
<!-- 指定連接數(shù)據(jù)庫(kù)的密碼 -->
<property name="password"
value="1234"/>
<!-- 指定連接數(shù)據(jù)庫(kù)連接池的最大連接數(shù) -->
<property name="maxPoolSize"
value="20"/>
<!-- 指定連接數(shù)據(jù)庫(kù)連接池的最小連接數(shù) -->
<property name="minPoolSize"
value="1"/>
<!-- 指定連接數(shù)據(jù)庫(kù)連接池的初始化連接數(shù) -->
<property name="initialPoolSize"
value="1"/>
<!-- 指定連接數(shù)據(jù)庫(kù)連接池的連接的最大空閑時(shí)間 -->
<property name="maxIdleTime"
value="20"/>
</bean>
|
在applicationContext.xml中配置sessionFactory
|
<bean id="dataSource"
class="org.springframework.jndi.JndiObjectFactoryBean">
<property name="jndiName"
value="java:comp/env/jdbc/news"></property>
</bean>
<!-- 管理Hibernate -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource"
ref="dataSource"></property>
<property name="mappingResources">
<list>
<value>org/bulktree/ssh2/news/vo/User.hbm.xml</value>
<value>org/bulktree/ssh2/news/vo/News.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<value>
hibernate.dialect=org.hibernate.dialect.MySQLDialect
</value>
</property>
</bean>
|
3. 開(kāi)始編碼：
我們必須明確Spring框架的體系結(jié)構(gòu)，新建以下幾個(gè)包
User.java
|
package org.bulktree.ssh2.news.vo;
publicclass User {
private String uid;
private String uname;
private String password;
public String getUid() {
returnuid;
}
Getter/setter’’’’’’’’’’’
publicvoid setPassword(String password)
{
this.password = password;
}
}
|
在User類(lèi)同包下即org.bulktree.ssh2.news.vo新建User.hbm.xml文件
|
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate
Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="org.bulktree.ssh2.news.vo">
<class name="User"
table="user">
<id column="uid"
name="uid" type="string">
<generator class="assigned"/>
</id>
<property column="uname"
name="uname" type="string"/>
<property column="password"
name="password" type="string"/>
</class>
</hibernate-mapping>
|
新建UserDao.java接口
|
package
org.bulktree.ssh2.news.dao;
import
java.util.List;
import
org.bulktree.ssh2.news.vo.User;
publicinterface UserDao {
/**
*增加一個(gè)用戶
*@throwsException
*/
publicvoid addUser(User
user) throws Exception;
/**
*根據(jù)uid/password查詢User
*@paramuid
*@parampassword
*@return
*@throwsException
*/
public User
queryByUidAndPassword(String uid, String password) throws Exception;
/**
*刪除用戶
*@paramuid
*@throwsException
*/
publicvoid delete(String
uid) throws Exception;
/**
*查詢?nèi)坑脩?/span>
*@returnList
*@throwsException
*/
public
List<User> queryAll() throws Exception;
}
|
UserDaoImpl.java接口實(shí)現(xiàn)類(lèi)
|
package
org.bulktree.ssh2.news.dao.impl;
import
java.util.List;
import
org.bulktree.ssh2.news.dao.UserDao;
import
org.bulktree.ssh2.news.vo.User;
import
org.springframework.orm.hibernate3.support.HibernateDaoSupport;
/**
* 繼承HibernateDaoSuppor類(lèi)實(shí)現(xiàn)getHibernateTemplate()
*
* @author bulktree
*
*/
public
class UserDaoImpl extends HibernateDaoSupport implements UserDao {
@Override
public void addUser(User user) throws
Exception {
this.getHibernateTemplate().save(user);
}
@Override
public void delete(String uid) throws
Exception {
// TODO Auto-generated method stub
}
@Override
public List<User> queryAll() throws
Exception {
// TODO Auto-generated method stub
return null;
}
@Override
public User queryByUidAndPassword(String
uid, String password)
throws Exception {
String hql = "FROM User as u WHERE
u.uid=? and u.password=?";
String[] str = new String[] { uid,
password };
List<User> users =
this.getHibernateTemplate().find(hql, str);
if (users != null &&
users.size() >= 1) {
return users.get(0);
} else {
return null;
}
}
}
|
Service層，新建一UserService.java接口
|
package org.bulktree.ssh2.news.service;
publicinterface UserService {
/**
*添加一個(gè)用戶
*@paramuid
*@paramuname
*@parampassword
*@return新增用戶的uid
*@throwsException
*/
public String addUser(String uid,
String uname, String password) throws Exception;
/**
*驗(yàn)證登錄
*@paramuid
*@parampassword
*@returnuid
*@throwsException
*/
public String isLogin(String uid,
String password) throws
Exception;
}
|
接口實(shí)現(xiàn)類(lèi)
|
package
org.bulktree.ssh2.news.service.impl;
import
org.bulktree.ssh2.news.dao.UserDao;
import
org.bulktree.ssh2.news.service.UserService;
import
org.bulktree.ssh2.news.vo.User;
/**
* UserService實(shí)現(xiàn)類(lèi)
*
* @author bulktree
*
*/
public
class UserServiceImpl implements UserService {
private UserDao userDao;
public void setUserDao(UserDao userDao) {
this.userDao = userDao;
}
@Override
public String addUser(String uid, String
uname, String password)
throws Exception {
User user = new User();
user.setUid(uid);
user.setUname(uname);
user.setPassword(password);
userDao.addUser(user);
return user.getUid();
}
@Override
public String isLogin(String uid, String
password) throws Exception {
User user =
userDao.queryByUidAndPassword(uid, password);
if(user != null) {
return user.getUname();
} else {
return null;
}
}
}
|
最后我們新建一Action，LoginAction.java
|
package
org.bulktree.ssh2.news.action;
import
java.util.Map;
import
org.bulktree.ssh2.news.service.UserService;
import
org.bulktree.ssh2.news.vo.User;
import
com.opensymphony.xwork2.ActionContext;
import
com.opensymphony.xwork2.ActionSupport;
/**
* 登錄Action
* @author bulktree
*
*/
public
class LoginAction extends ActionSupport {
private User user;
private UserService userService;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService
userService) {
this.userService = userService;
}
@Override
public String execute() throws Exception {
if (isInvalid(user.getUid())) {
this.addFieldError("uid",
"登錄ID不能為空");
return INPUT;
}
if (isInvalid(user.getPassword())) {
this.addFieldError("password",
"密碼項(xiàng)不能為空");
return INPUT;
}
String uname =
userService.isLogin(user.getUid(), user.getPassword());
if (uname != null) {
Map session =
ActionContext.getContext().getSession();
session.put("uname",
uname);
session.put("uid",
user.getUid());
return SUCCESS;
} else {
this.addFieldError("idorpassword",
"登錄ID或密碼錯(cuò)誤");
return INPUT;
}
}
private boolean isInvalid(String value) {
return (value == null || value.length()
== 0);
}
}
|
下來(lái)就是login.jsp頁(yè)面文件了
|
<center>
<div style="color:
red"><s:fielderror /><s:actionmessage /></div>
<s:form action="login"
method="post">
<s:textfield name="user.uid"
label="UID" tooltip="ENTER
YOUR UID" />
<s:password name="user.password"
label="PASSWORD"
tooltip="ENTER
YOUR PASSWORD" />
<s:submit></s:submit>
</s:form>
<s:a href="regist.jsp">REGIST NEW COUNT</s:a></center>
|
下來(lái)就是applicationContext.xml文件的配置
|
<bean id="userdao"
class="org.bulktree.ssh2.news.dao.impl.UserDaoImpl">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<!--
bean配置 -->
<bean id="newsdao"
class="org.bulktree.ssh2.news.dao.impl.NewsDaoImpl">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<bean id="loginAction"
class="org.bulktree.ssh2.news.action.LoginAction">
<property name="userService">
<ref bean="userservice"/>
</property>
</bean>
</bean>
|
·bean的id屬性就是對(duì)應(yīng)類(lèi)class的實(shí)例
·property元素的name屬性為bean的class屬性對(duì)應(yīng)類(lèi)的屬性名，
·ref為引用bean，引用的是bean的id
Struts.xml文件完整配置
|
<?xml version="1.0"
encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
"-//Apache Software Foundation//DTD Struts Configuration
2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.i18n.encoding"
value="UTF-8" />
<package name="SSH2"
extends="struts-default">
<action name="login"
class="loginAction">
<result>/addNews.jsp</result>
<result name="input">/login.jsp</result>
</action>
<action name="regist"
class="registAction">
<result>/login.jsp</result>
<result name="input">/regist.jsp</result>
</action>
<action name="listall"
class="listallAction">
<result>/newsList.jsp</result>
<result name="input">/addNews.jsp</result>
</action>
<action name="notice"
class="noticeAction">
<result type="redirect-action">listall</result>
<result name="input">/addNews.jsp</result>
</action>
</package>
</struts>
|
·form表單的action對(duì)應(yīng)struts.xml文件中的action的name屬性，由于Strust由Spring管理，struts.xml文件中的action元素class屬性對(duì)應(yīng)的是applicationContext.xml文件中bean元素id屬性
最后貼上完整的applicationContext.xml文件

|
·applicationContext.xml文件默認(rèn)加載路徑classpath下，也就是WEB-INF下
·整個(gè)工程沒(méi)有用到hibernate.cfg.xml文件，Spring管理了hibernate,這個(gè)文件不起什么作用了，但是最好還是加上
|
