罗嗦一下：经过struts，hibernate ，spring三个框架的非系统学习，，最后将三者整合起来，，今天下午开会完毕，晚上就再搞一下，尝试从简单着手，经过修改，最后搭建成功，具体步骤如下：
首先是整个web project的工程目录结构图，具体如下：
1，创建web工程，然后导入struts2,spring,hibernate的包，可以单独建立一个lib文件夹，放在其中，然后通过add jar 放到library中，，
2，创建domain包，然后创建名为UserVo.java的持久化类文件，创建名为UserVo.hbm.xml的持久化类映射文件,,,,,,（对应的数据库schema为fcshopping，表为uservo） 代码如下：
UserVo.java
View Code
package domain;
public class UserVo {
private Integer userId;
private String userName;
private String passWord;
public UserVo() {
}
public UserVo(String userName, String passWord) {
this.userName = userName;
this.passWord = passWord;
}
public Integer getUserId() {
return this.userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public String getUserName() {
return this.userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassWord() {
return this.passWord;
}
public void setPassWord(String passWord) {
this.passWord = passWord;
}
}
UserVo.hbm.xml:
View Code
<?xml version="1.0" encoding="utf-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="domain.UserVo" table="uservo" catalog="fcshopping"> <id name="userId" type="java.lang.Integer"> <column name="userID" /> <generator class="native"></generator> </id> <property name="userName" type="java.lang.String"> <column name="userName" length="20" not-null="true" /> </property> <property name="passWord" type="java.lang.String"> <column name="passWord" length="20" not-null="true" /> </property> </class> </hibernate-mapping>
3，在dao包中创建持久化类的接口以及该接口的实现类，具体如下：
接口UserDAO.java:
View Code
package dao; import java.util.List; import domain.UserVo; public interface UserDAO{ public List<UserVo> findByProperty(String userName,String userPsw); }
接口实现类UserDAOImpl.java:
View Code
package dao; import java.util.List; import domain.UserVo; import org.springframework.orm.hibernate3.support.HibernateDaoSupport; public class UserDAOImpl extends HibernateDaoSupport implements UserDAO{ @SuppressWarnings("unchecked") public List<UserVo> findByProperty(String userName,String userPsw){ String sql="from UserVo u where u.userName='"+userName+"'and u.passWord = '"+userPsw+"'"; List<UserVo> list=(List<UserVo>)getHibernateTemplate().find(sql); return list; } }
4,在service包中创建业务层的接口以及该接口的实现类，具体如下：
接口UserService.java:
View Code
package service;
import domain.UserVo;
public interface UserService {
public UserVo validateUser(String userName,String userPsw);
}
接口实现类UserServiceImpl.java:
View Code
package service;
import dao.UserDAO;
import domain.UserVo;
public class UserServiceImpl implements UserService{
private UserDAO userDAO;
public UserDAO getUserDAO() {
return userDAO;
}
public void setUserDAO(UserDAO userDAO) {
this.userDAO = userDAO;
}
public UserVo validateUser(String userName,String userPsw){
if(userDAO.findByProperty(userName, userPsw).size()!=0){
return userDAO.findByProperty(userName, userPsw).get(0);
}
return null;
}
}
5,在action包中创建用户登录模块的action类LoginAction.java:
View Code
package action;
import service.UserService;
import domain.UserVo;
import com.opensymphony.xwork2.ActionSupport;
@SuppressWarnings("serial")
public class LoginAction extends ActionSupport {
/**
* @return
*/
private UserVo user;
private UserService userService;
public UserVo getUser() {
return user;
}
public void setUser(UserVo user) {
this.user = user;
}
public UserService getUserService() {
return userService;
}
public void setUserService(UserService userService) {
this.userService = userService;
}
public String execute()throws Exception {
// TODO Auto-generated method stub
UserVo u=userService.validateUser(user.getUserName(), user.getPassWord());
if(u!=null){
return SUCCESS;
}
else{
return ERROR;
}
}
}
6,为解决中文乱码问题，在包filter中创建过滤器：
CharacterEncodingFilter.java:
View Code
package filter;
import java.io.IOException;
import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
public class CharacterEncodingFilter implements Filter {
private String characterEncoding;//编码方式在web.xml中
private boolean enabled;//是否启动filter，初始值在web.xml中
@Override
public void init(FilterConfig config) throws ServletException {
// TODO Auto-generated method stub
//初始化时加载参数
//从配置文件中读取设置到编码方式
characterEncoding=config.getInitParameter("characterEncoding");
//启动该过滤器完成编码方式到修改
enabled="true".equalsIgnoreCase(characterEncoding.trim())
||"1".equalsIgnoreCase(characterEncoding.trim());
}
@Override
public void doFilter(ServletRequest request, ServletResponse response,
FilterChain chain) throws IOException, ServletException {
// TODO Auto-generated method stub
if(enabled||characterEncoding!=null){
request.setCharacterEncoding(characterEncoding);//设置request编码方式
response.setCharacterEncoding(characterEncoding);//设置response编码方式
}
chain.doFilter(request, response);//doFilter将修改好的request和response参数向下传递；
}
@Override
public void destroy() {
// TODO Auto-generated method stub
characterEncoding=null;
}
}
7,Struts2配置文件代码如下：
struts2.xml:
View Code
<?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> <include file="struts-default.xml"></include> <package name="main" extends="struts-default"> <action name="login" class="action.LoginAction"> <result name="success">/success.jsp</result> <result name="error">/error.jsp</result> </action></package></struts>
struts.properties:
View Code
struts.objectFactory=spring
struts.action.extension=action
struts.locale=en_GB
8,applicationContext.xml文件的代码如下：
View Code
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" 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"> <bean id="datasource" class="org.apache.commons.dbcp.BasicDataSource"> <property name="driverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost:3306/fcshopping"></property> <property name="username" value="root"></property> <property name="password" value="lpshou"></property> </bean> <bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"> <property name="dataSource"> <ref bean="datasource"></ref> </property> <property name="hibernateProperties"> <props> <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> </props> </property> <property name="mappingResources"> <list> <value>domain/UserVo.hbm.xml</value> </list> </property> </bean> <bean id="userDAO" class="dao.UserDAOImpl"> <property name="sessionFactory"><ref local="sessionFactory"/></property> </bean> <bean id="userService" class="service.UserServiceImpl"> <property name="userDAO"><ref bean="userDAO"></ref></property> </bean> <bean id="login" class="action.LoginAction"> <property name="userService"><ref bean="userService"></ref></property> </bean> </beans>
9，在web.xml文件中配置Spring,Sturts2的监听，具体：
View Code
<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- struts2过滤器 --> <filter> <filter-name>struts</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> <init-param> <param-name>struts.action.extension</param-name> <param-value>action</param-value> </init-param> </filter> <filter-mapping> <filter-name>struts</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 字符集过滤器 --> <filter> <filter-name>characterEncodingFilter</filter-name> <filter-class>filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>characterEncoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>enable</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- spring的监听 --> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/classes/applicationContext.xml</param-value> </context-param> </web-app>
10，用户登录模块，包含三个部分，分别时login.jsp, success.jsp, error.jsp,具体如下：
login.jsp:
View Code
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="struts" %> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>登录页面</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <center> <h2>用户登录</h2><p> <struts:form action="login" method="post"> <struts:textfield name="user.userName" label="帐号："></struts:textfield> <struts:password name="user.passWord" label="密码:"></struts:password> <struts:submit value="登录"></struts:submit> </struts:form> </center> </body> </html>
success.jsp:
View Code
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <%@ taglib uri="/struts-tags" prefix="struts" %> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'success.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> <center><h2>欢迎登录</h2></center><br/> 你好！用户：<struts:property value="user.userName"/>登录成功 </body> </html>
error.jsp:
View Code
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <base href="<%=basePath%>"> <title>My JSP 'error.jsp' starting page</title> <meta http-equiv="pragma" content="no-cache"> <meta http-equiv="cache-control" content="no-cache"> <meta http-equiv="expires" content="0"> <meta http-equiv="keywords" content="keyword1,keyword2,keyword3"> <meta http-equiv="description" content="This is my page"> <!-- <link rel="stylesheet" type="text/css" href="styles.css"> --> </head> <body> 登录失败 </body> </html>
11,启动tomcat，发布工程即可，测试成功。
