好久没有搭建框架了,今天整理下以前的知识,整合下SSH,没想到手生了,一时半会各种异常出来,经过一番挣扎后,终于搞出来了雏形,

下面是我做整合框架的笔记,如果大家开发过程中又遇到的情况,可以参考下

首先是包的结构,(命名不算正规哈~,临时写的仓促了点)

框架是基于JAR包的基础上构建的,所以必须必备的jar包必须先下好,

如图:

没有的可以在本文源代码里下:

搭建框架:

修改web.xml, 加入 struts配置

<?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>

<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>

</web-app>

创建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">

<struts>

<package name="struts2" extends="struts-default">

<action name="login" class="test.action.loginAction">

<result name="success" type="redirect">index.jsp</result>

<result name="input">login.jsp</result>

<result name="error">login.jsp</result>

</action>

</package>

</struts>

接下来我们创建一个 测试用的ACTION类,loginAction

package test.action;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

public String username;

public String password;

public String execute(){

if(!username.equals("admin")){

super.addFieldError("username", "用户名错误!");

return ERROR;

}

if(!password.equals("001")){

super.addFieldError("password", "密码错误!");

return ERROR;

}

return SUCCESS;

}

public void validate(){

if(username==null||username.length()==0){

super.addActionError("用户名不能为空");

}

if(password==null||password.length()==0){

super.addActionError("密码不能为空");

}

}

}

为了方便我们调试strut是否有效,我们创建一个login.jsp  用于测试

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

<%@ taglib prefix="s" uri="/struts-tags" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>登录</title>

<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="cache-control" content="no-cache">

<meta http-equiv="expires" content="0">

</head>

<body>

<s:form name="form1" action="login" >

<s:textfield  name="username" label="username" ></s:textfield>

<s:password name="password" label="password" ></s:password>

<s:submit label="submit"></s:submit>

</s:form>

<s:actionerror/>

</body>

</html>

修改下index.jsp 页面 登陆成功则友好提示一下

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>

<%

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 'index.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">

</head>

<body>

login success. <br>

</body>

</html>

使用tomcat加载项目,如果启动时候不爆出异常,说明strust 基本配置完成,我们进入页面

如果登陆成功则转到

Index.jsp

接下配置spring 和hibernate

重新回归到  web.xml

我们在其中添加,spring的相关配置

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>

classpath:spring/applicationContext*.xml

</param-value>

</context-param>

<listener>

<listener-class>

org.springframework.web.context.ContextLoaderListener

</listener-class>

</listener>

创建applicationContext.xml 文件 我们在此使用注解驱动(其实说真的,spring到后面不用注解去写,也就失去它本身的意义,精髓就在于注解的简洁和易用)

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p"

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">

<aop:aspectj-autoproxy />

<context:annotation-config></context:annotation-config>

<context:component-scan base-package="test" />

<bean id="sessionFactory"

class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="configLocation">

<value>classpath:spring/hibernate.cfg.xml</value>

</property>

</bean>

<!-- 配置事务管理器 -->

<bean id="transactionManager"

<property name="sessionFactory">

<ref bean="sessionFactory" />

</property>

</bean>

<bean id="hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">

<property name="sessionFactory">

</property>

</bean>

<tx:advice id="smAdvice" transaction-manager="transactionManager" >

<tx:attributes>

<tx:method name="save*" propagation="REQUIRED" />

<tx:method name="del*" propagation="REQUIRED" />

<tx:method name="update*" propagation="REQUIRED" />

</tx:attributes>

</tx:advice>

<aop:config>

<aop:pointcut id="smMethod" expression="execution(* test.service.impl.*.*(..))" />

<aop:advisor pointcut-ref="smMethod" advice-ref="smAdvice" />

</aop:config>

</beans>

创建hibernate.cfg.xml  (用户名密码,可以自己修改一下)

<?xml version='1.0' encoding='UTF-8'?>

<!DOCTYPE hibernate-configuration PUBLIC

"-//Hibernate/Hibernate Configuration DTD 3.0//EN"

"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

<hibernate-configuration>

<session-factory>

<property name="connection.driver_class">com.mysql.jdbc.Driver</property>

<property name="connection.url">jdbc:mysql://localhost/test?characterEncoding=utf-8</property>

<property name="myeclipse.connection.profile">com.mysql.jdbc.Driver</property>

<property name="connection.username">root</property>

<property name="connection.password">123456</property>

<property name="dialect">org.hibernate.dialect.MySQLDialect</property>

<property name="show_sql">true</property>

<mapping resource="test/hibernate/TUser.hbm.xml" />

</session-factory>

</hibernate-configuration>

创建相关DTO类,以及hbm.xml 配置文件

TUser.java

package test.hibernate;

public class TUser implements java.io.Serializable {

private int userid ;

private String username;

private String allname;

private String address;

public String getUsername() {

return this.username;

}

public void setUsername(String username) {

this.username = username;

}

public String getAllname() {

return this.allname;

}

public void setAllname(String allname) {

this.allname = allname;

}

public String getAddress() {

return this.address;

}

public void setAddress(String address) {

this.address = address;

}

public int getUserid() {

return userid;

}

public void setUserid(int userid) {

this.userid = userid;

}

}

TUser.hbm.xml

<?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="test.hibernate.TUser" table="tuser">

<id name="userid" type="java.lang.Integer" column="userid">

<generator class="increment"></generator>

</id>

<property name="username" type="string" column="username" />

<property name="allname" type="string" column="allname" />

<property name="address" type="string" column="address" />

</class>

</hibernate-mapping>

由于测试关系,我们在这里就省略了DAO层,直接写service层类去测试 ,采用注解标记

创建相关service 接口以及实现类

IUserService.java

package test.service.imp;

import java.util.List;

import test.hibernate.TUser;

public interface IUserService {

public void saveTuser(TUser user);

public List<TUser> getUserById( String id);

}

UserServiceImpl.java

package test.service.impl;

import java.sql.SQLException;

import java.util.List;

import javax.annotation.Resource;

import org.hibernate.HibernateException;

import org.hibernate.Query;

import org.hibernate.Session;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.orm.hibernate3.HibernateCallback;

import org.springframework.orm.hibernate3.HibernateTemplate;

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Propagation;

import org.springframework.transaction.annotation.Transactional;

import test.hibernate.TUser;

import test.service.imp.IUserService;

@Service("userServiceImpl")

public class UserServiceImpl implements IUserService {

@Resource(name = "hibernateTemplate")

private HibernateTemplate hibernateTemplate;

public void saveTuser(TUser user) {

hibernateTemplate.save(user);

hibernateTemplate.flush();

}

@SuppressWarnings("unchecked")

@Transactional(propagation=Propagation.REQUIRED)

public List<TUser> getUserById(String id) {

final String ids = id;

//List<TUser> list = hibernateTemplate.find("from TUser where userid = ?");

List<TUser> list =hibernateTemplate.executeFind(new HibernateCallback() {

public List<TUser> doInHibernate(Session session) throws HibernateException,

SQLException {

Query query =  (Query) session.createQuery("from TUser where userid = ? ");

query.setString(0, ids);

return  query.list() ;

}

});

return list;

}

}

接下来我们写一个main 主类来测试我们的spring 和hibernate

SpringTest.java

package test.spring;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import org.springframework.stereotype.Component;

import test.hibernate.TUser;

import test.service.imp.IUserService;

@Component("springTest")

public class SpringTest {

@Resource(name = "userServiceImpl")

private IUserService userService ;

public static void main( String[] args ) {

//加载spring配置文件,初始化IoC容器

ApplicationContext ac = new ClassPathXmlApplicationContext("spring/applicationContext.xml");

//从容器 接管Bean

//        TUser user = (TUser) ac.getBean("TUser");

//输出欢迎信息

//        System.out.println( "Hello:" + user.getUsername() + ";u is in " + user.getAddress() + " ; and b is  " + user.getAllname() );

//        SessionFactory ss = (SessionFactory) ac.getBean("sessionFactory");

//        HibernateTemplate ht = new HibernateTemplate(ss);

//        HibernateTemplate ht = (HibernateTemplate) ac.getBean("hibernateTemplate");

//

//        List<TUser> list =    ht.find("from TUser ");

SpringTest st =(SpringTest) ac.getBean("springTest");

//        TUser tu = new TUser();

//        tu.setAddress("河西");

//        tu.setAllname("河西走廊");

//        tu.setUserid(45);

//        tu.setUsername("故乡");

//

//        st.userService.saveTuser(tu);

List<TUser> list = st.userService.getUserById("4");//ID在数据库内找到相应的

for(TUser xx : list){

System.out.println(xx.getAddress()+"||"+xx.getAllname()+"||"+xx.getUsername());

}

}

}

如果出现下面提示,说明你的配置已经完成
