只有Struts2基础（初学Hibernate/Spring第三天就想着整合），有些地方不是很懂，看了网上大部分的例子、blog，百分百的MyEclipse插件，本人不太习惯使用MyEclipse，主要是Eclipse使用的时间比较长，使用MyEclipse6.0.1时（第一次用）比如你要输入.getHibernateTemplate()时，输入点时就有提示，但是当我输入点后面的字母出错时，只能返回到输入点之前才按点“.”可以提示，按ALT+/也不会出现，是不是我不知道快捷键，或是其它的方式，总之我在Eclipse中输入一半错误时按ALT+/可以又出来提示，虽然不是特依赖提示功能，但是用起来还是不爽，毕竟每天都在使用它，哪位要是知道的话烦请告诉一声
bulktree@126.com。
仅仅看了两天的官方文档就写了这个整合的新闻发布系统，感觉蛮好的，是个好的开始 come on!
以下是一个新闻发布系统的登录模块：（两天看文档，一夜写成的，不是很完善，仅仅实现基本的增删查改功能，主要是整合练习）
首先配置三个框架，有人说要是使用MyEclipse自动生成会有顺序Spring->Hibernate->Struts,太依赖工具不是本人的习惯，这些是后话。
开发工具Eclipse J2EE Developer Tomcat6.0.13 Mysql 6.0
新建Dynamic Web Project
拷贝工程所需的jar包到WEB-INF/lib下
数据库创建脚本
DROPTABLE context;
CREATETABLE context
(
id VARCHAR(32) NOTNULLPRIMARYKEY,
title VARCHAR(100),
times DATETIME,
content VARCHAR(500),
author VARCHAR(50),
click INT,
typeVARCHAR(50)
);
DROPTABLEuser;
CREATETABLEuser
(
uid VARCHAR(50) NOTNULLPRIMARYKEY,
uname VARCHAR(50),
password VARCHAR(50) NOTNULL
);
在web.xml中配置Struts2和Spring
Struts2
org.apache.struts2.dispatcher.FilterDispatcher
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encodingFilter
UTF-8
Struts2
/*
org.springframework.web.context.ContextLoaderListener
项目中我使用的是Tomcat数据源配置如下，如果你不使用Tomcat数据源也可以在下面的配置文件中配置：
也在在配置applicationContext.xml文件中配置数据源
在applicationContext.xml中配置sessionFactory
class="org.springframework.jndi.JndiObjectFactoryBean">
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
org/bulktree/ssh2/news/vo/User.hbm.xml
org/bulktree/ssh2/news/vo/News.hbm.xml
hibernate.dialect=org.hibernate.dialect.MySQLDialect
3. 开始编码：
我们必须明确Spring框架的体系结构，新建以下几个包
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类同包下即org.bulktree.ssh2.news.vo新建User.hbm.xml文件
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
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 {
/**
*增加一个用户
*@throwsException
*/
publicvoid addUser(User user) throws Exception;
/**
*根据uid/password查询User
*@paramuid
*@parampassword
*@return
*@throwsException
*/
public User queryByUidAndPassword(String uid, String password) throws Exception;
/**
*删除用户
*@paramuid
*@throwsException
*/
publicvoid delete(String uid) throws Exception;
/**
*查询全部用户
*@returnList
*@throwsException
*/
public List queryAll() throws Exception;
}
UserDaoImpl.java接口实现类
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;
/**
* 继承HibernateDaoSuppor类实现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 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 users = this.getHibernateTemplate().find(hql, str);
if (users != null && users.size() >= 1) {
return users.get(0);
} else {
return null;
}
}
}
Service层，新建一UserService.java接口
package org.bulktree.ssh2.news.service;
publicinterface UserService {
/**
*添加一个用户
*@paramuid
*@paramuname
*@parampassword
*@return新增用户的uid
*@throwsException
*/
public String addUser(String uid, String uname, String password) throws Exception;
/**
*验证登录
*@paramuid
*@parampassword
*@returnuid
*@throwsException
*/
public String isLogin(String uid, String password) throws Exception;
}
接口实现类
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实现类
*
* @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;
}
}
}
最后我们新建一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;
/**
* 登录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", "登录ID不能为空");
return INPUT;
}
if (isInvalid(user.getPassword())) {
this.addFieldError("password", "密码项不能为空");
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", "登录ID或密码错误");
return INPUT;
}
}
private boolean isInvalid(String value) {
return (value == null || value.length() == 0);
}
}
下来就是login.jsp页面文件了
tooltip="ENTER YOUR PASSWORD" />
REGIST NEW COUNT
下来就是applicationContext.xml文件的配置
·bean的id属性就是对应类class的实例
·property元素的name属性为bean的class属性对应类的属性名，
·ref为引用bean，引用的是bean的id
Struts.xml文件完整配置
"-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
"http://struts.apache.org/dtds/struts-2.0.dtd">
/addNews.jsp
/login.jsp
/login.jsp
/regist.jsp
/newsList.jsp
/addNews.jsp
listall
/addNews.jsp
·form表单的action对应struts.xml文件中的action的name属性，由于Strust由Spring管理，struts.xml文件中的action元素class属性对应的是applicationContext.xml文件中bean元素id属性
最后贴上完整的applicationContext.xml文件
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
class="org.springframework.jndi.JndiObjectFactoryBean">
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
org/bulktree/ssh2/news/vo/User.hbm.xml
org/bulktree/ssh2/news/vo/News.hbm.xml
hibernate.dialect=org.hibernate.dialect.MySQLDialect
·applicationContext.xml文件默认加载路径classpath下，也就是WEB-INF下
·整个工程没有用到hibernate.cfg.xml文件，Spring管理了hibernate,这个文件不起什么作用了，但是最好还是加上
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
org.hibernate.dialect.MySQLDialect
package="com.bulktree.ssh2.vo" resource="com/bulktree/ssh2/vo/User.hbm.xml"/>
