  • springMVC+Hibernate配置

    本文描述下 sypro 项目中使用 springMVC+Hibernate配置，初学SpringMVC做下简单整理解。

    1.web项目首先我们要使用 web.xml文件将 spring配置引入进来

    部署applicationContext的xml文件，如果在web.xml中不写任何参数配置信息，默认的路径是”/WEB-INF /applicationContext.xml，在WEB-INF目录下创建的xml文件的名称必须是applicationContext.xml。 如果是要自定义文件名可以在web.xml里加入contextConfigLocation如下，在<param-value> </param-value>里指定相应的xml文件名，如果有多个xml文件，可以写在一起并一“,”号分隔

    Xml代码  收藏代码
    1. <display-name>sypro2.02</display-name>  
    2.     <context-param>  
    3.         <param-name>contextConfigLocation</param-name>  
    4.         <param-value>classpath:spring.xml,classpath:spring-hibernate.xml,classpath:spring-ehcache.xml,classpath:spring-apacheFtpServer.xml</param-value>  
    5.     </context-param>  
    6.       
    7.     <filter>  
    8.         <filter-name>openSessionInViewFilter</filter-name>  
    9.         <filter-class>org.springframework.orm.hibernate4.support.OpenSessionInViewFilter</filter-class>  
    10.         <init-param>  
    11.             <param-name>singleSession</param-name>  
    12.             <param-value>true</param-value>  
    13.         </init-param>  
    14.     </filter>  


    加载contextConfigLocation则交给监听来实现

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



    然后配置springMVC处理请求映射

    15.         <url-pattern>*.do</url-pattern>  
    16.     </servlet-mapping>  



    2.applicationContext.xml 文件常用配置，在该项目中使用的自定义写法 将 applicationContext.xml 重命名为： spring-mvc.xml ,注意如果不使用自定义写法applicationContext.xml则存放在 /WEB-INF/applicationContext.xml目录且不可重命名

    applicationContext.xml （spring-mvc.xml） 常用配置如下：
