ssh2整合记录

1. 下面给出整合开发时Struts 2、 Hibernate、Spring需要的JAR。

lib/required/*.jar

<3> hibernate 注解安装包下的(下载路径：www.hibernate.org，点击“Hibernate Annotations”右边的“Downloads”):

hibernate-annotations.jar

lib/ejb3-persistence.jar、hibernate-commons-annotations.jar

<4> Hibernate针对JPA的实现包(下载路径：www.hibernate.org，点击“Hibernate Entitymanager”右边的“Downloads”):

hibernate-entitymanager.jar

lib/test/log4j.jar、slf4j-log4j12.jar

<5> Spring安装包下的

dist/spring.jar

lib/c3p0/c3p0-0.9.1.2.jarlib/aspectj/aspectjweaver.jar、aspectjrt.jarlib/cglib/cglib-nodep-2.1_3.jar

lib/j2ee/common-annotations.jarlib/log4j/log4j-1.2.15.jarlib/jakarta-commons/commons-logging.jar

<6> MYSQL数据库驱动jar

2. 在源文件夹下新建Spring配置文件beans.xml，在配置文件中配置c3p0数据源：

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

<property name="driverClass" value="org.gjt.mm.mysql.Driver"/>

<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/itcast?useUnicode=true&amp;characterEncoding=UTF-8"/>

<property name="user" value="root"/>

<property name="password" value="123456"/>

<!--初始化时获取的连接数，取值应在minPoolSize与maxPoolSize之间。Default: 3 -->

<property name="initialPoolSize" value="1"/>

<!--连接池中保留的最小连接数。-->

<property name="minPoolSize" value="1"/>

<!--连接池中保留的最大连接数。Default: 15 -->

<property name="maxPoolSize" value="300"/>

<!--最大空闲时间,60秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 -->

<property name="maxIdleTime" value="60"/>

<!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 -->

<property name="acquireIncrement" value="5"/>

<!--每60秒检查所有连接池中的空闲连接。Default: 0 -->

<property name="idleConnectionTestPeriod" value="60"/>

</bean>

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">

..... 略 </bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">

<property name="dataSource" ref="dataSource"/>

<property name="mappingResources">

<list>

<value>cn/itcast/bean/Person.hbm.xml</value>

</list>

</property>

<property name="hibernateProperties">

<value>

hibernate.dialect=org.hibernate.dialect.MySQL5Dialect

hibernate.hbm2ddl.auto=update

hibernate.show_sql=false

hibernate.format_sql=false

</value>

</property>

</bean>

<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

<property name="sessionFactory" ref="sessionFactory"/>

</bean>

<tx:annotation-driven transaction-manager="txManager"/>

---

3. 实体bean配置模版.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 package="cn.itcast.bean">

<class name="Person" table="person">

<id name="id" type="integer" >

<generator class="native"/>

</id>

<property name="name" length="10" not-null="true"/>

</class>

</hibernate-mapping>

---

4. 在web容器中实例化spring容器和配置struts2

<1> <!-- 指定spring的配置文件，默认从web根目录寻找配置文件，我们可以通过spring提供的classpath:前缀指定从类路径下寻找 -->

<context-param>

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

<param-value>classpath:beans.xml</param-value>

</context-param>

<!-- 对Spring容器进行实例化 -->

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<2> 配置struts2

<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>

<3> struts2的配置文件模版struts.xml如下。常量struts.objectFactory=spring明确指出将由Spring负责创建Action实例。

<?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>

<!-- 默认的视图主题 -->

<constant name="struts.ui.theme" value="simple" />

<constant name="struts.objectFactory" value="spring" />

<package name="person" namespace="/person" extends="struts-default">

<global-results>

<result name="message">/WEB-INF/page/message.jsp</result>

</global-results>

<action name="action_*" class="personList" method="{1}">

<result name="list">/WEB-INF/page/persons.jsp</result>

<result name="add">/WEB-INF/page/add_person.jsp</result>

<result name="edit">/WEB-INF/page/edit_person.jsp</result>

</action>

</package>

</struts>

---

5. 为了能从spring容器中寻找到Action bean，要求action配置的class属性值和spring中bean的名称相同。如下:

<package name="itcast" namespace="/person" extends="struts-default">

<action name="list" class="personListAction">

.....

</action>

</package>
