Struts2.3.16.1+Hibernate4.3.4+Spring4.0.2 框架整合（转）

原文  http://blog.csdn.net/songanling/article/details/22454973

最新版Struts2+Hibernate+Spring整合

    目前为止三大框架最新版本是：

     struts2.3.16.1

     hibernate4.3.4

     spring4.0.2 

    其中struts2和hibernate的下载方式比较简单，但是spring下载有点麻烦，可以直接复制下面链接下载最新版spring

 http://repo.springsource.org/libs-release-local/org/springframework/spring/4.0.2.RELEASE/spring-framework-4.0.2.RELEASE-dist.zip  

 

一. 所需的jar包（其中aopaliance-1.0.jar，是spring所依赖的jar，直接复制粘贴到谷歌百度就有的下载）

框架

版本

所需jar包

Struts2

2.3.16.1

Hibernate

4.3.4

spring

4.0.2

其它

 无

CREATE TABLE `user` (

 `id` int(11) NOT NULL AUTO_INCREMENT,

 `user_name` varchar(20) DEFAULT NULL,

 `password` varchar(20) DEFAULT NULL,

 `address` varchar(100) DEFAULT NULL,

 `phone_number` varchar(20) DEFAULT NULL,

 `create_time` datetime DEFAULT NULL,

 `update_time` datetime DEFAULT NULL,

 PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULTCHARSET=utf8;

并插入一条数据

INSERT INTO `user` VALUES ('1', 'test','test', 'test', 'test', '2014-03-29 00:48:14', '2014-03-29 00:48:17');

三. 先看下myeclipse的目录结构

 

四. 配置文件

1. web.xml

<?xml version="1.0" encoding="UTF-8"?><web-app version="3.0"   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_3_0.xsd">  <display-name></display-name>    <!-- 添加对spring的支持 -->  <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>classpath:applicationContext.xml</param-value>  </context-param>    <listener>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  </listener>    <!-- 添加对struts2的支持 -->  <filter>    <filter-name>struts2</filter-name>    <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>  </filter>   <!-- 当hibernate+spring配合使用的时候，如果设置了lazy=true,那么在读取数据的时候，当读取了父数据后，  hibernate会自动关闭session，这样，当要使用子数据的时候，系统会抛出lazyinit的错误，    这时就需要使用spring提供的 OpenSessionInViewFilter,OpenSessionInViewFilter主要是保持Session状态    知道request将全部页面发送到客户端，这样就可以解决延迟加载带来的问题 -->   <filter>    <filter-name>openSessionInViewFilter</filter-name>    <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>    <init-param>      <param-name>singleSession</param-name>      <param-value>true</param-value>    </init-param>  </filter>    <filter-mapping>    <filter-name>struts2</filter-name>    <url-pattern>/*</url-pattern>  </filter-mapping>   <filter-mapping>    <filter-name>openSessionInViewFilter</filter-name>    <url-pattern>*.do,*.action</url-pattern>  </filter-mapping>    <welcome-file-list>    <welcome-file>index.jsp</welcome-file>  </welcome-file-list></web-app>

2. applicationContext.xml

3. db.properties

db.driverClassName=com.mysql.jdbc.Driverdb.url=jdbc:mysql://localhost:3306/testdb.username=rootdb.password=root

4. hibernate.cfg.xml

<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration>  <session-factory>    <property name="dialect">org.hibernate.dialect.MySQLDialect</property>    <property name="jdbc.batch_size">20</property>    <property name="connection.autocommit">true</property>    <!-- 显示sql语句 -->    <property name="show_sql">true</property>    <property name="connection.useUnicode">true</property>    <property name="connection.characterEncoding">UTF-8</property>    <!-- 缓存设置 -->    <property name="cache.provider_configuration_file_resource_path">/ehcache.xml</property>    <property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</property>    <property name="cache.use_query_cache">true</property>  </session-factory></hibernate-configuration>

5. struts.xml

<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-configuration PUBLIC  "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"><hibernate-configuration>  <session-factory>    <property name="dialect">org.hibernate.dialect.MySQLDialect</property>    <property name="jdbc.batch_size">20</property>    <property name="connection.autocommit">true</property>    <!-- 显示sql语句 -->    <property name="show_sql">true</property>    <property name="connection.useUnicode">true</property>    <property name="connection.characterEncoding">UTF-8</property>    <!-- 缓存设置 -->    <property name="cache.provider_configuration_file_resource_path">/ehcache.xml</property>    <property name="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</property>    <property name="cache.use_query_cache">true</property>  </session-factory></hibernate-configuration>
