SSH最新集成

        首先，我想声明一点，本人是个极度菜鸟，SSH纯靠自学。所以我做的笔记将是最基本的，大家不要见笑。我会的我想师兄姐们一定一看就会。
        下面我以spring-framework-2.5.6.SEC01，struts-2.2.1，hibernate-distribution-3.5.5-Final为例一步步的集成。

一、下载SSH的个子压缩文件，并解压
    spring：     http://www.springsource.org/download
    hibernate：  http://www.hibernate.org/downloads.html
    struts：     http://struts.apache.org/download.cgi
二、新建一个web项目，比如我以SSHTest为例。
三、开始引入相应的jar包。（将所需要的包copy到web项目的lib目录下）
    1，引入struts相关的jar包（8个）：
        commons-logging-1.0.4.jar
        freemarker-2.3.16.jar
        struts2-core-2.2.1.jar
        xwork-core-2.2.1.jar
        ognl-3.0.jar
        commons-fileupload-1.2.1.jar
        commons-io-1.3.2.jar
        javassist-3.9.0.GA.jar
    注意：红色部分为该版本的struts所必需的jar包，红色加粗的在hibernate和spring中都有。
    2，引入hibernate相关的jar包（11个）：
        commons-collections-3.1.jar
        antlr-2.7.6.jar
        dom4j-1.6.1.jar
        hibernate-commons-annotations.jar //需下载
        hibernate-jpa-2.0-api-1.0.0.Final.jar
        hibernate3.jar
        jta-1.1.jar
        slf4j-api-1.5.8.jar
        slf4j-nop-1.5.2.jar  //需下载slf4j http://www.slf4j.org/download.html
       
        mysql-connector-java-5.1.13-bin.jar 数据库连接驱动（mysql）//需下载 http://dev.mysql.com/downloads/connector/j/3.1.html
    3，引入spring相关的jar包（2个）。
        spring.jar
        struts2-spring-plugin-2.2.1.jar  //此jar包在解压的struts中找，是struts和spring集成所需的
        提示：
          我们可以分别导入struts、hibernate、spring时配合后面所描述的第四步，逐步做个简单的测试。：
    四、配置对应的xml文件
        1，struts
          新建一包xml，xml包下新建struts.xml文件

<?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>
	<!--<constant name="struts.enable.DynamicMethodInvocation" value="false" />-->
	<constant name="struts.devMode" value="true" />

	<package name="default" namespace="/" extends="struts-default">
		<action name="login">
			<result>
				success.jsp
			</result>
		</action>
	</package>
</struts>

        1.1  WebRoot下新建一success.jsp文件
          1.2  将项目加载到tomcat并启动，在浏览器里输入http://localhost:8088/SSHTest/login验证是否配置正确
        2，hibernate
          2.1  xml包新建hibernate.cfg.xml,配置：

<?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>
		<!-- Database connection settings -->
		<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
		<property name="connection.url">jdbc:mysql://localhost:3306/test</property>
		<property name="connection.username">root</property>
		<property name="connection.password">root</property>

		<!-- JDBC connection pool (use the built-in) -->
		<property name="connection.pool_size">1</property>

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

		<!-- Enable Hibernate's automatic session context management -->
		<property name="current_session_context_class">thread</property>

		<!-- Disable the second-level cache  -->
		<property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

		<!-- Echo all executed SQL to stdout -->
		<property name="show_sql">true</property>

		<!-- Drop and re-create the database schema on startup -->
		<property name="hbm2ddl.auto">update</property>

		<mapping class="com.entity.User"/>

	</session-factory>

</hibernate-configuration>

          2.2  建一实体包com.entity,在该包里建一User实体类

package com.entity;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
public class User {
	private int userId;
	private String userName;
	private String userPassword;
	@Id
	@GeneratedValue
	public int getUserId() {
		return userId;
	}
	public void setUserId(int userId) {
		this.userId = userId;
	}
	public String getUserName() {
		return userName;
	}
	public void setUserName(String userName) {
		this.userName = userName;
	}
	public String getUserPassword() {
		return userPassword;
	}
	public void setUserPassword(String userPassword) {
		this.userPassword = userPassword;
	}
	
}

          2.1  写一测试类

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.AnnotationConfiguration;
import org.hibernate.cfg.Configuration;
import org.junit.Test;
import com.entity.User;

public class SshTest {
	@Test
	public void testHibernate(){
		Configuration cft = new AnnotationConfiguration().configure("xml/hibernate.cfg.xml");
		SessionFactory sf = cft.buildSessionFactory();
		Session s = sf.openSession();
		s.beginTransaction();
		User u = new User();
		s.save(u);
		s.getTransaction().commit();
	}
}

         如果运行后数据库生成了表，则表示配置成功。
        3，  spring
