web容器中实例化spring相关配置说明

web容器中实例化spring相关配置说明:

 要想在web容器实例化时加载spring容器,web.xml文件中配置如下:

 <context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>classpath:bean.xml</param-value>
</context-param>
<!-- 对Spring容器进行实例化的监听器s -->
<listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

 

说明:

     默认情况下spring实例化时加载的是/WEB-INF/下的applicationContext.xml

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

 <param-value>classpath:bean.xml</param-value>指定了spring需要加载的文件(类路径下的bean.xml文件)

   如果配置文件有多个配置如下:

     <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            classpath*:conf/spring/applicationContext_core*.xml,
            classpath*:conf/spring/applicationContext_dict*.xml,
            classpath*:conf/spring/applicationContext_hibernate.xml,
            classpath*:conf/spring/applicationContext_staff*.xml,
            classpath*:conf/spring/applicationContext_security.xml
            classpath*:conf/spring/applicationContext_modules*.xml
            classpath*:conf/spring/applicationContext_cti*.xml
            classpath*:conf/spring/applicationContext_apm*.xml
        </param-value>
    </context-param>

 

或者(使用空格隔开,如下配置:)

          <CONTEXT-PARAM>
         <PARAM-NAME>contextConfigLocation</PARAM-NAME>
         <PARAM-VALUE>
               applicationContext-database.xml  applicationContext.xml
         </PARAM-VALUE>  
     </CONTEXT-PARAM>
