一、新建web项目
1.创建web项目ssh2
2.将项目添加到tomcat中
<context path=”/ssh2” docBase=“H:workspace201306ssh2WebRoot”
reloadable=”true”/>
3.测试 http://localhost:8080/ssh2/
二、给项目添加jar包
1.手动添加struts所需jar
commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
commons-logging-1.0.4.jar（在hibernate中存在可以不添加）
freemarker-2.3.15.jar
ongl-2.7.3.jar
struts2-core-2.1.8.jar
struts2-spring-plugin-2.1.8.jar(主要用于sptruts与spring的整合)
xwork-core-2.1.6.jar
2.通过myEclipse的add hibernate Capabilities添加hibernate3.2的jar包
注意:
1)勾选copy checked Library Jars to project and add to build-path
2)commons-logging-1.0.4.jar在hibernate及struts中同时存在保留一个
3.通过myEclipse的add spring Capabilities添加spring2.5的jar包
Spring2.5 AOP Libraries(选中第三项时自动勾选)
Spring2.5 Core Libraries
Spring2.5 Persistence Core Libraries
Spring2.5 Web Libraries
注意：
1）Copy checked Library contents to project folder(TLDS always copied)
2）applicationContext.xml必须指定放到WebRoot/WEB-INF目录下
3)不要勾选Create Spring SessionFactory that references
4)asm.jar是由hibernate引入的jar,asm-2.2.3.jar是spring引入的jar,它们是同
一个jar,必须进入WebRootWEB-INFlib文件夹中删除一个就行，我删除后面的一个.
4.添加连接池
Commons-dbcp-1.3.jar
Commons-pool-1.5.5.jar
5.添加数据库
ojdbc14.jar
6.添加日志支持
slf4j-api-1.5.8.jar
slf4j-log4j12-1.5.8.jar
并将log4j.properties拷贝到src目录下
三、修改及添加配制文件
1.web.xml
<?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">
<!-- 下面是struts过滤器 -->
<filter>
<filter-name>struts2</filter-name>
<filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter
</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- 下面是spring的监天器 -->
<listener>
<listener-class>
org.springframework.web.context.ContextLoaderListener
</listener-class>
</listener>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
2.添加applicationContext.xml
3.添加struts.xml
四、创建项目包
1．com.test.action
2．com.test.bean
3．com.test.dao
4．com.test.dao
5．com.test.dao.impl
6．com.test.service
7．com.test. service.impl
8. com.test.util
五、代码编写
1.编写bean和相应的映射文件
User.java
package com.test.bean;
public class User {
private int id;
private String firstname;
private String lastname;
private int age;
public int getId() {
return id;}
public void setId(int id) {
this.id = id;}
public String getFirstname() {
return firstname;}
public void setFirstname(String firstname) {
this.firstname = firstname;}
public String getLastname() {
return lastname;}
public void setLastname(String lastname) {
this.lastname = lastname;}
public int getAge() {
return age;}
public void setAge(int age) {
this.age = age;}
}
User.hbm.xml
<?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>
<class name="com.test.bean.User" table="users">
<id name="id" column="id" type="int">
<generator class="native">
</generator>
</id>
<property name="firstname" column="firstname"
type="string"></property>
<property name="lastname" column="lastname"
type="string"></property>
<property name="age" column="age"
type="int"></property>
</class></hibernate-mapping>
2.编写持久层dao及daoimpl
UserDAO.java
package com.test.dao;
import java.util.List;
import com.test.bean.User;
public interface UserDAO {
public void saveUser(User user);
public List<User> findAllUsers();
public void removeUser(User user);
public void updateUser(User user);
public User findUserById(Integer id);}
UserDAOImpl.java
package com.test.dao.impl;
import java.util.List;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import com.test.bean.User;
import com.test.dao.UserDAO;
public class UserDAOImpl extends HibernateDaoSupport implements UserDAO {
public void saveUser(User user) {
this.getHibernateTemplate().save(user); }
@SuppressWarnings("unchecked")
public List<User> findAllUsers() {
String hql = "from User user order by user.id desc";
return (List<User>) this.getHibernateTemplate().find(hql); }
public void removeUser(User user) {
this.getHibernateTemplate().delete(user); }
public void updateUser(User user) {
this.getHibernateTemplate().update(user); }
public User findUserById(Integer id) {
User user = (User) this.getHibernateTemplate().get(User.class, id);
return user; }
}
3.编写业务层service及serviceimpl
UserService.java
package com.test.service;
import java.util.List;
import com.test.bean.User;
public interface UserService {
public void save(User user);
public List<User> findAll();
public void delete(User user);
public User findById(Integer id);
public void update(User user);
}
UserServiceImpl.java
package com.test.service.impl;
import java.util.List;
import com.test.bean.User;
import com.test.dao.UserDAO;
import com.test.service.UserService;
public class UserServiceImpl implements UserService {
private UserDAO userDao;
public void save(User user) {
userDao.saveUser(user);// 完成业务逻辑 }
public List<User> findAll() {
return this.userDao.findAllUsers(); }
public UserDAO getUserDao() {
return userDao; }
public void setUserDao(UserDAO userDao) {
this.userDao = userDao; }
public void delete(User user) {
this.userDao.removeUser(user); }
public User findById(Integer id) {
return this.userDao.findUserById(id); }
public void update(User user) {
this.userDao.updateUser(user); }
}
4.编写action
SaveUserAction.java
package com.test.action.user;
import com.opensymphony.xwork2.ActionSupport;
import com.test.bean.User;
import com.test.service.UserService;
public class SaveUserAction 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 {
//调用service相关的方法,完成实际的业务逻辑处理
userService.save(user);
return this.SUCCESS;
}
}
ListUserAction.java
package com.test.action.user;
import java.util.Map;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.test.service.UserService;
public class ListUserAction extends ActionSupport {
private UserService userService;
public UserService getUserService() {
return userService; }
public void setUserService(UserService userService) {
this.userService = userService; }
@Override
public String execute() throws Exception {
Map request= (Map)ActionContext.getContext().get("request");
request.put("list", this.userService.findAll());
return this.SUCCESS; }
}
RemoveUserAction.java
package com.test.action.user;
import com.opensymphony.xwork2.ActionSupport;
import com.test.bean.User;
import com.test.service.UserService;
public class RemoveUserAction 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 {
userService.delete(user);
return this.SUCCESS;}
}
UpdatePUserAction.java
package com.test.action.user;
import com.opensymphony.xwork2.ActionSupport;
import com.test.bean.User;
import com.test.service.UserService;
public class UpdatePUserAction 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 {
user = userService.findById(user.getId());
return SUCCESS; }
}
UpdateUserAction.java
package com.test.action.user;
import com.opensymphony.xwork2.ActionSupport;
import com.test.bean.User;
import com.test.service.UserService;
public class UpdateUserAction 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 {
userService.update(user);
return this.SUCCESS; }
}
5.配制applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

6.配制struts.xml
<?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">
