Struts1+spring+hibernate整合时几个关键的类

一.当然是加载struts1的ActionServlet,在web.xml中配置

<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>

二.是加载spring的applicationContext的类,有三种方式,分别对应三个类

1.在web.xml中用ContextLoaderServlet加载

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/source-config.xml,/WEB-INF/dao-config.xml,/WEB-INF/action-config.xml</param-value>
</context-param>
<!--利用servlet加载,如果有多个spring配置文件,须设置全局的常量<context-param>
否则，spring配置文件必须是applicationContext.xml
-->
<ervlet>
<servlet-name>context</servlet-name>
<servlet-class>org.springframework.web.context.ContextLoaderServlet</servlet-class>
<load-on-startup>0</load-on-startup>
</servlet>

2.在web.xml中用ContextLoaderListener加载

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/source-config.xml,/WEB-INF/dao-config.xml,/WEB-INF/action-config.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

3.在strutx.xml中用ContextLoaderPlugIn加载

<plug-in className="org.springframework.web.struts.ContextLoaderPlugIn">
<set-property property="contextConfigLocation" value="/WEB-INF/source-config.xml,/WEB-INF/dao-config.xml,/WEB-INF/action- config.xml"/>
</plug-in>

三.struts到spring转发的两种方式,分别对应两个类

1.在struts.xml用DelegatinActionProxy转发

<action-mappings>
<action path="/register"
name="registerForm" type="org.springframework.web.struts.DelegatingActionProxy"
input="/register.jsp">
<forward name="success" path="/success.jsp"></forward>
</action>
</action-mappings>

action的path属性对应spring配置文件bean的name属性

2.在struts.xml用DelegatingRequestProcessor转发

<controller processorClass="org.springframework.web.struts.DelegatingRequestProcessor"></controller>

在action中不用配置type属性

四.spring和hiberante结合时几个类

1.初始化数据库连接的类,有几种方式

一是用spring提供的jdbc连接类DriverManagerSource,如下

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver"/>
<property name="url" value="jdbc:microsoft:sqlserver://localhost:1433;databasename=test"/>
<property name="username" value="sa"/>
<property name="password" value="129127"/>
</bean>

二是用c3p0连接池ComboPooleDataSource,如下:

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="com.mysql.jdbc.Driver"></property>
<property name="jdbcUrl" value="jdbc:mysql://localhost:3306/chuanqi"></property>
<property name="user" value="root"></property>
<property name="password" value="129127"></property>
<property name="minPoolSize" value="5"></property>
<property name="maxPoolSize" value="40"></property>
<property name="initialPoolSize" value="5"></property>
<property name="maxIdleTime" value="20"></property>
</bean>

三是用dbcp连接池BasicDataSource,jar包为common-dbcp-XXX.jar和c3p0配置差不多,但现在已不推荐使用.

2.SessionFactory类LocalSesssionFactoryBean

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource"/>
</property>
<property name="mappingResources">
<list>
<value>com/chuanqi/hibernate/vo/Classinfo.hbm.xml</value>
<value>com/chuanqi/hibernate/vo/Courseinfo.hbm.xml</value>
<value>com/chuanqi/hibernate/vo/Knowledgeinfo.hbm.xml</value>
<value>com/chuanqi/hibernate/vo/Question.hbm.xml</value>
<value>com/chuanqi/hibernate/vo/Userinfo.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.jdbc.batch_size">20</prop>
</props>
</property>
</bean>

3事务配置方式两种,一种是传统的TransactionProxyFactoryBean和HiberanteTransactionManager的结合

<bean id="transcationManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
<!-- 配置事务 -->
<bean id="proxyTemplate" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager" ref="transcationManager"></property>
<property name="target">
<ref bean="business"></ref>
</property>
<property name="transactionAttributes">
<props>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>

另一种是用拦截器TransactionInterceptor,HibernateTransactionManager和BeanNameAutoProxyCreator三个类完成

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>

<bean id="tranactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
<property name="transactionManager" ref="transactionManager"></property>
<property name="transactionAttributes">
<props>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
<prop key="*">PROPAGATION_REQUIRED</prop>
</props>
</property>
</bean>
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<list>

<!--这里可以配置多个业务逻辑-->
<value>userBusi</value>
</list>
</property>

<property name="interceptorNames">
<list>

<!--这里可以配置多个拦截器-->
<value>tranactionInterceptor</value>
</list>
</property>
</bean>
