Struts1.2+Spring2.5+Hibernate3.2框架搭建（四）

3.2. 配置 web.xml 文件

     在web.xml文件中配置监听器以及web应用的初始化参数：

    <!-- 向监听器类中传递初始化参数，以获取beanFactory对象 -->

    <context-param>

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

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

    </context-param>

    <!--

       使用监听器初始化Spring的beanFactory,并将其放入到Context中，在使用时将其取出，以获取IOC容器中的bean

    -->

    <listener>

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

    </listener>

在web.xml文件中配置Spring中的过滤器解决中文乱码问题

    <!-- 使用Spring中的过滤器解决中文乱码问题 -->

    <filter>

       <filter-name>characterEncodingFilter</filter-name>

       <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

       <init-param>

           <param-name>encoding</param-name>

           <param-value>UTF-8</param-value>

       </init-param>

       <init-param>

           <param-name>forceEncoding</param-name>

           <param-value>true </param-value>

       </init-param>

</filter>

    <filter-mapping>

       <filter-name>characterEncodingFilter</filter-name>

       <url-pattern>/*</url-pattern>

</filter-mapping>

在web.xml文件中配置Spring中的过滤器解决hibernate延迟加载的问题

    <!-- 解决hibernate延迟加载带来的异常，配置过滤器使Session在请求完成之后再关闭 -->

    <filter>

       <filter-name>OpenSessionInViewFilter</filter-name>

       <filter-class>

           com.zlk.util.OpenSessionInViewFilter</filter-class>

       <init-param>

           <param-name>singleSession</param-name>

           <param-value>true</param-value>

       </init-param>

</filter>

    <filter-mapping>

       <filter-name>OpenSessionInViewFilter</filter-name>

       <url-pattern>/*</url-pattern>

</filter-mapping>

注：我重写了org.springframework.orm.hibernate3.support.OpenSessionInViewFilter类

下面是我重写的类：

① com.zlk.override.OpenSessionInViewFilter

package com.zlk.override;

 

import org.hibernate.FlushMode;

import org.hibernate.Session;

import org.hibernate.SessionFactory;

import org.springframework.dao.DataAccessResourceFailureException;

import org.springframework.orm.hibernate3.SessionFactoryUtils;

 

public class OpenSessionInViewFilter extends

       org.springframework.orm.hibernate3.support.OpenSessionInViewFilter {

 

    protected void closeSession(Session session, SessionFactory sessionFactory) {

       // TODO Auto-generated method stub

        session.flush();

       super.closeSession(session, sessionFactory);

    }

 

    protected Session getSession(SessionFactory sessionFactory)

           throws DataAccessResourceFailureException {

       // TODO Auto-generated method stub

        Session session = SessionFactoryUtils.getSession(sessionFactory, true); 

        this.setFlushMode(FlushMode.COMMIT);

        return session;   

    }

 

}

② com.zlk.util.OpenSessionInViewFilter

package com.zlk.util;

 

public class OpenSessionInViewFilter extends

       com.zlk.override.OpenSessionInViewFilter {

 

}
