关于ssh2的配置
这个例子是在javaeye的某位大虾的博客中用的例子上整理而成的（地址为：http://lcj1112.iteye.com/blog/462673），在根据大虾的步骤做的时候，类库和代码中还遇到了一些配置问题，所以这里再进行整理了一遍。
所以代码上面基本和大虾一样，还有一些没被调用的方法，这里因为只是整理ssh2的配置，因此没有清理。大家心里知道就好。
eclipse里面配置好server，然后新建web工程。
工程中导入jar包
1.修改web.xml
2.新建三个简单的jsp页面
若login页面出现不了输入框，则是没有倒入struts2包。
3.新建一个user的bean
4.新建一个action类。
5.在src的目录下建立一个struts.xml。
若启动时出现语法错误，则是xml的schema有错误或者没有schema。
6.新建一个PoUser的bean作为hibernate的映射对象
7.新建一个*.hbm.xml写上具体的映射方式
8.新建一个pouser的hibernate具体实现类，接口这里不贴出了。
9.新建一个bo业务类，接口类就不贴出来了。
10.在web-inf下新建一个applicationContext.xml,配置spring
11.检查一下工程，然后测试。

eclipse里面配置好server，然后新建web工程。

1.修改web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <display-name>TestSSH</display-name> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <filter> <filter-name>struts2</filter-name> <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>index.html</welcome-file> <welcome-file>index.htm</welcome-file> <welcome-file>index.jsp</welcome-file> <welcome-file>default.html</welcome-file> <welcome-file>default.htm</welcome-file> <welcome-file>default.jsp</welcome-file> </welcome-file-list> </web-app>
2.新建三个简单的jsp页面
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<s:form action="action_executeFunction" namespace="/">
名称:<s:textfield name="user.name"/>
密码：<s:textfield name="user.password"/>
<input type="submit" value="submit"/>
</s:form>
</body>
</html>
若login页面出现不了输入框，则是没有倒入struts2包。
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
this is success page!
</body>
</html>
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
this is faild page!
</body>
</html>
3.新建一个user的bean
package bean;
public class User {
private int id ;
private String name ;
private String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
4.新建一个action类。
package action;
import service.ILoginBo;
import bean.PoUser;
import bean.User;
import com.opensymphony.xwork2.ActionSupport;
import com.sun.corba.se.spi.orbutil.fsm.ActionBase;
import com.sun.corba.se.spi.orbutil.fsm.FSM;
import com.sun.corba.se.spi.orbutil.fsm.Input;
public class LoginAction extends ActionSupport{
public String getSUCCESS() {
return SUCCESS;
}
public void setSUCCESS(String sUCCESS) {
SUCCESS = sUCCESS;
}
public String getERROR() {
return ERROR;
}
public void setERROR(String eRROR) {
ERROR = eRROR;
}
public String getINPUT() {
return INPUT;
}
public void setINPUT(String iNPUT) {
INPUT = iNPUT;
}
private User user;
private ILoginBo loginBo ;
private String SUCCESS = "success";
private String ERROR = "error";
private String INPUT = "input";
public String input() throws Exception {
this.user.setName("root");
// return INPUT;
return SUCCESS;
}
public void validateExecuteFunction() throws Exception{
if(user.getName() == null || user.getPassword() == null ){
this.redraw();
}
}
public String executeFunction() throws Exception {
//ILoginBo loginBean = (ILoginBo)this.appContext.getBean("LoginBo");
if(!loginBo.isExits(user.getName())){
loginBo.addUser(user);
return SUCCESS;
}
return ERROR;
}
public String redraw() throws Exception {
return ERROR;
}
public ILoginBo getLoginBo() {
return loginBo;
}
public void setLoginBo(ILoginBo loginBo) {
this.loginBo = loginBo;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
5.在src的目录下建立一个struts.xml。
若启动时出现语法错误，则是xml的schema有错误或者没有schema。
<?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>
<!-- 配置中文支持 -->
<constant name="struts.custom.i18n.resources" value="alternate" />
<!-- 配置Spring-->
<constant name="struts.objectFactory" value="spring" />
<package name="user" namespace="/" extends="struts-default">
<global-results>
<result name="message">/WEB-INF/page/message.jsp</result>
</global-results>
<action name="action_*" method="{1}"
class="action.LoginAction" >
<result name="input">login.jsp</result>
<result name="error">error.jsp</result>
<result name="success">success.jsp</result>
</action>
</package>
</struts>
6.新建一个PoUser的bean作为hibernate的映射对象
package bean;
public class PoUser {
private int id ;
private String name ;
private String password ;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
7.新建一个*.hbm.xml写上具体的映射方式
<?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="bean.PoUser" table="user" >
<id name="id" type="java.lang.Integer">
<column name="id" length="4" />
</id>
<property name="name" type="java.lang.String" not-null="true">
<column name="username" length="30" />
</property>
<property name="password" type="java.lang.String">
<column name="password" length="30" />
</property>
</class>
</hibernate-mapping>
8.新建一个pouser的hibernate具体实现类，接口这里不贴出了。
package dao.hibernate;
import org.springframework.orm.hibernate3.support.HibernateDaoSupport;
import dao.IUserDao;
import bean.PoUser;
public class UserDaoImpl extends HibernateDaoSupport implements IUserDao{
@Override
public void saveUser(PoUser poUser) {
this.getHibernateTemplate().saveOrUpdate(poUser);
}
public PoUser getUser(){
return (PoUser) this.getHibernateTemplate().find("select 1 from user");
}
}
9.新建一个bo业务类，接口类就不贴出来了。
package service.impl;
import bean.PoUser;
import bean.User;
import dao.IUserDao;
import service.ILoginBo;
public class LoginBoImpl implements ILoginBo {
private IUserDao userDao ;
public IUserDao getUserDao() {
return userDao;
}
public void setUserDao(IUserDao userDao) {
this.userDao = userDao;
}
@Override
public boolean isExits(String name) {
// TODO Auto-generated method stub
if(name.equals("htc")){
return true;
}
return false;
}
@Override
public void addUser(User user) {
// TODO Auto-generated method stub
try{
PoUser poUser = new PoUser();
poUser.setId(0);
poUser.setName(user.getName());
poUser.setPassword(user.getPassword());
this.userDao.saveUser(poUser);
}catch(Exception ex){
ex.printStackTrace();
}
}
}
10.在web-inf下新建一个applicationContext.xml,配置spring
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:amq="http://activemq.apache.org/schema/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<!-- 这里scope="prototype"代表Action层不是单例模式，每次请求都会新创建一个对象 -->
<bean id="loginActionBean" class="action.LoginAction"
scope="prototype">
<property name="loginBo" ref="loginBo" />
<property name="user" ref="userBean" />

<!--Dao事务代理Bean的配置 -->
<bean id="daoTemplate"

</beans>
11.检查一下工程，然后测试。
