文章主要探究了web容器中实例化spring的相关配置简单介绍,接下来我们看看具体内容。
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>
总结
以上就是本文关于web容器中实例化spring相关配置解析的全部内容,希望对大家有所帮助.
